In Pediatric Surgery, always remember:“Call Early, Call Often”
“Children are NOT little adults”
“You don’t know what you don’t know”
“Bilious vomiting is a surgical emergency until proven otherwise”
“A baby has no language but a cry”
“Primum non nocere”
“Before anything else, do no harm”
“But also, do some GOOD”
“To cure sometimes, to CARE always”
476-2538 - 24/7/365
Prayer of the Newborn Undergoing Surgery:Let them keep me warm,
Let them keep my airway clear,
Let them maintain my blood volume,
And please LORD, let them get me right the first time.
IntroductionThis manual is intended to serve as an orientation to the Pediatric Surgical Service at Parnassus. Wesee and treat a wide breadth of problems on this service. Management of pediatric surgical patientsrequires constant attention to detail with little margin for error. The tempo of disease processes inchildren can be quite rapid. Be careful when ordering medications and intravenous solutions—dosages for pediatric patients are based on mg/kg. There are always plenty of resources available,particularly if the care of children is new to you. For any problem that arises, always err on the sideof too much communication rather than too little communication with the attending. You may not knowwhat you don’t know when it comes to the care of children. Remember, children are NOT littleadults!
FTC/Pediatric Surgery OfficeThe FTC/Pediatric Surgery Office is located at 400 Parnassus, 1st floor, Room A-123 (next to theclinical lab). Our office staff and nurses are located in this area. There may be times when you arepaged by the Nurse Practitioner to see a patient here. There is one exam room with limited supplies.This area is only used for drop-in or urgent patients. Sometimes the attending surgeon may alsoschedule a patient to be seen here during non-clinic hours.
Important Phone NumbersAll numbers are area code 415 unless stated otherwise.

Resident ResponsibilitiesPlease meet with Dr. Hirose 3 times during your rotation (start, middle, end)
The residents on the Pediatric Surgery team are responsible for the following activities:
Patient ListPlease confirm the patient lists on APEX daily: short list and active list.
Keep inactive surgical patients on short list until discharge.
Do not sign off on surgical patients without consulting with attending.
HoursResident work hours must be logged on a weekly basis.
Hours will be reviewed at Wednesday am conference.
No full weekend call is permitted.
Submit schedule to Dr. Hirose before starting.
RoundsPatient rounds and notes should be completed prior to AM cases starting in the OR. Attending walkrounds will be done on a daily basis. Page the surgical nurse (443-4088) to “15” at the beginning ofdaily rounds.
Please notify the attending surgeon of all significant changes in patient condition, regardless of thetime of day.
AdmissionsPromptly inform attending surgeon of any new admissions & consults. The majority of outsidereferrals are received directly by the attending surgeon, via the answering service (476-2538), or bythe hospitalist service. If you receive a call directly from an outside pediatrician/hospital, please taketheir name, hospital and contact number and promptly report to attending. Do not accept any patientsto the pediatric surgical service without approval of the attending surgeon.
All accepted inter-facility intensive care transports are to be referred to the fellow of the neonatalICU (3-1565) or the pediatric ICU (3-1352), as appropriate, for coordination of admission. Aneonatal transport is considered for any patient under 30 days of age. Emergent admissions to thepediatric acute care floor should be coordinated with the pediatric transfer center (1-877-UC
CHILD).
Attending PhysicianThe schedule for the attending physician changes weekly and may also include differentnight/weekend coverage. Please check with the office or attending on service regarding the on callschedule.
Attendings: Phone CallsCall attending directly or positively ascertain attending has been notified upon the followingsituations:
Death (even if expected)Cardiac arrestRespiratory failure either requiring intubation or significantly increased O2 demands.Severe respiratory distressAirway issuesTransfer to ICU or higher level of careConcern that patient needs a procedure or operationA new need for acute dialysisBleeding requiring transfusionHypotension/hemodynamic instabilitySymptomatic and severe hypertensionSignificant new arrhythmiaSuspected MISuspected PENew onset severe chest painNew onset severe abdominal painAbrupt deterioration in neurologic exam or profound decreased mental statusSignificant change in neurovascular exam of extremityPatient or family wishes to speak to the attendingPatient wishes to be discharged AMA
Plus
Any other significant change in clinical status of patient that is of major concernAny new admissionThe arrival of a patient accepted in transfer from another institution
ConsultationsPerform consultations requested by other services including the Pediatric and Neonatal ICUs. The
consultation template must include the name of the requesting attending physician (even if a residentrequests the consult).
ICN ConsultationsWhen rounding in the ICN, remove lab coat and jewelry (watches, bracelets, and rings). Roll upsleeves. Scrub hands prior to patient contact once in the AM. Check with nurse before examiningpatients.
Operating RoomThe pediatric surgery service has block time in the main OR on the following days: Monday all day,Tuesday AM, Thursday all day, Friday all day. Residents should check the OR schedule ahead oftime and review the relevant imaging, learn the patient history, and read about operative managementprior to each case.
Provide operating room coverage as assigned. Residents must be in the OR by 7:15 am for first cases.A clinic letter (in APEX for patients evaluated at UCSF) will suffice as the H&P, provided that thephysical exam has been updated. Our service is not to be the reason for any delays into the OR (i.e.no H&P or consent).
Cases may be scheduled through our office (Brian at 6-2539 or 6-8080) up to 11 am the day prior.After this time, cases are placed as add-ons at the front desk after 3 pm the day prior (353-1545).Some prenatally diagnosed cases may be scheduled under the mother’s medical record number. Thisinformation will need to be updated after the infant is born.
All operative forms and operative dictations are to be completed by the attending surgeon.
Patient ManagementThe surgical team works closely with the PICU and ICN teams for any surgical patient in these units.Management plans are discussed with these primary services on a daily basis. If a surgical procedureis performed on a patient and we are NOT the primary team covering this patient, a transfer orderform is required in the PACU to return the patient to the floor.
Following communication from our team regarding the surgical procedure and care, the primary teamwill complete the remaining orders. It is very important to call the primary team after all operationsso that they can prepare to accept the patient back on the ward. In general, if there are any questions,consult the attending surgeon regarding to which team a patient belongs.
All patients less than 40 kg require PEDIATRIC order forms. This is a home call service; however,verbal orders are RARELY accepted. The SOD and/or pediatric on call resident may also be willingto write routine orders for you if you are on home call. If there is any question, it is probably mostprudent to try to clarify orders prior to leaving the hospital.
This may be the first “home call” experience for some residents. New consults require return to thehospital for evaluation. It is less clear when to return to evaluate inpatients and it is difficult to create
specific guidelines for each clinical scenario. Certainly, any significant change in vital signs wouldprompt a return, as would airway, breathing, or bleeding issues. When in doubt, come in. If an hourviolation would result, call attending and inform him/her of problem.
ClinicAttend outpatient clinic Wednesday at 1:00 pm. The clinic is located on the second floor of theAmbulatory Care Center. Patients are seen in consultation with the attending surgeon. All clinicdictations are performed by the attending surgeon.
Discharge plansDiscuss anticipated discharge plan with the family on rounds early. The goal of the pediatric floors isto have discharges by 11 am. Notify the discharge planner and pharmacist on call 48 hours prior toplanned discharge. The discharge planner will help to set up follow-up clinic appointments, medicalsupplies, and home nursing. The on-call pharmacist will help complete the prescription forms, callthe prescriptions into the pharmacy, and resolve any pharmacy-related issues (i.e. insurance).
Note: There are no pediatric pharmacists here on the weekend. Please call and notify the pharmaciston Friday for anticipated weekend discharges. Discharge orders should be written early in themorning on the day of discharge. Patients must be discharged by 11 am, or the family will be chargedfor an additional day of hospital stay.
Most patients do not need to return to the office for a follow-up visit and are discharged to the care oftheir primary provider. Those patients who require a specific postoperative intervention need toreturn for a clinic visit (such as patients who undergo anorectal operations and require anal dilation).When in doubt about the need for a clinic visit, ask the attending or surgical nurse.
For inpatients, the discharge coordinator will schedule follow-up clinic appointments. Foroutpatients and 23 hour stays, the parents are asked to call our office at 476-2538 to schedule anappointment or contact the surgery team for postoperative questions and/or phone follow-up in 2weeks. Please give each family our business card.
Patients who only need phone follow-up/no clinic visit are:
Umbilical hernia, epigastric hernia, inguinal hernia (lap and open), simple non-perf’d appy, pyloricstenosis, lap chole, lumps/bumps, urachal remnants, hydrocele.
No phone follow-up/no clinic visit: lines.
LIFE ClinicLong-term Infant-to-adult Follow-up and Evaluation
LIFE clinic is available for patients with CDH, Hirschsprung’s disease, imperforate anus, esophagealatresia, sacrococcygeal teratomas, choledochal cysts/biliary atresia and CCAM/CPAM andpulmonary sequestrations. These clinics are offered monthly to annually. Contact the pediatric surgery
NP to determine if a patient is eligible for a LIFE clinic appointment at the time of discharge.
Social WorkerPediatric Surgery has an assigned social worker to assist families during their hospitalization. Shecan assist our families with questions about housing, insurance and community resources. Our socialworkers can be reached at 443-3988 and 443-8663 (pager). In the ICN: 443-9603 (pager).

SedationAvoid painful procedures in children. We use the OR and general anesthesia liberally in children.Conscious sedation can also be performed by the sedation team. There are pediatric guidelines forpainful procedures like blood drawing and tube removal/dressing changes. Please ask the nurse fordetails.
Procedural SupportFor any anticipated invasive, painful, or anxiety-provoking procedures at the bedside, please callChild Life and the bedside nurse before the procedure to prepare the child and family. Please use the
treatment room for patients on the pediatric floor.
Family SupportChild life services and social workers are available to support patients and families through thehospital experience. Please make referrals as needed.
Bowel PreparationPlease check with the attending of the week before starting the prep.
In House:Infants may be admitted the day prior for bowel preps.
IV hydration is required for this age group during the prep.
Begin at noon or sooner:
1. Start IV: D5 1/2 NS with 20 meq KCl/L at maintenance2. Place NG tube3. Begin golytely 25 ml/kg/hr via NG tube for 4-6 hours, or until stool is clear4. Pedialyte or clear liquids ad lib until patient NPO for OR
Ask attending for maximum fluid limit for golytely prep and additional instructions re: stoma/rectalirrigations.
Outpatient: Bowel preps can be done at home for older patients, however we may need to admit them if they arenot tolerating the prep:
Miralax Cleanout Instructions (5 days)5 days prior – Miralax 1 capful in 8 ounces of water or juice Q am and pm daily2 days prior – clear liquid diet1 day prior – 14 capsuls of Miralax in 64 ounces of Gatorade. Finish by early afternoon.Dulcolax 5 mg pill at 3pm and 9 pm. If unable to take Dulcolax pill, can take Senna ex-lax 7.5 mgat 3pm and 9pm. Clear liquid diet until NPO after midnight.
Rectal IrrigationRectal irrigation volumes should be 10-15 ml/kg of normal saline. Infants can become severelyhyponatremic if tap water enemas are performed!

Guidelines for RBC transfusionDo not order any blood product transfusion without consulting with the attending surgeon first.Anemia is well-tolerated by otherwise healthy children. Blood consent will be required.
All patients: Hemorrhagic shock not responding to 2 crystalloid fluid boluses (20 cc/kg x 2).Infants and children: Hct < 21%Neonates:
Hct < 30% if receiving < 35% Fi02, if on CPAP or mechanical ventilation, if having A&Bspells, if P > 180 or RR > 80, or if undergoing surgeryHct < 35% if receiving > 35% Fi02 or on mechanical ventilation with MAP 6-8 cm H20Hct < 40% for critically ill neonatesHct < 45% for critically ill hypoxic (pa02 < 60) neonates or neonates with cyanotic congenitalheart disease
Note: no absolute indications for transfusion based on Hct. If patient is stable and no further bloodloss is expected, transfusions may be held.
Table for amount of transfusion based on current hct, target hct, and body weight is in Harriet Lane.
Generally, 10cc/kg is roughly equivalent to tranfusion of 1 unit in an adult.
Central LinesPlease clarify with the referring service to determine what the line is for and what type of line isneeded. The requesting attending should document the type of line needed in APEX prior to the OR.Not all patients require a CXR in the PACU following line placement, please consult with theattending surgeon.
Broviac (1 or 2 lumens, power or silastic)Portacath
Vascath for dialysis/pheresisPermacath for dialysis/pheresis Look at fever curveCheck CBC and platelet count especially if the patient is on chemotherapy
Central line problemsClotted: A hospital policy is in place, based on tPA administration. Available from thepharmacy.Broken: Repair broken broviac catheters with appropriate repair kit. Each type of broviaccatheter has its own specific type of repair kit based on size and number of lumens. They arelocated in the 6Long Treatment room Pyxis.Infected: Treat the patient with systemic antibiotics (through the line) to “sterilize” the line ifpossible. Remove the line, after discussion with the chief resident or attending, if the patient is inseptic shock, the infection persists for > 3 days, a tunnel infection is present, or if the gram stainis positive for yeast, fungi, or AFB.
Central Lines/Broviacs/PortsIn general, we place lines in the operating room with ultrasound and fluoroscopy. Occasionally, wewill place them at the bedside in a NICU or PICU patient.
Central lines are percutaneously placed, using seldinger technique and are held in place withsutures. Removal does not need a trip to the OR.Broviacs are tunneled catheters that can be left in place long term. Initially, a nylon suture is usedto keep them in place, but ultimately, they are held in place by tissue ingrowth around asubcutaneous cuff. Removal usually requires a trip to the OR or at least sedation in the NICU orPICU.Ports are completely subcutaneous devices that are connected to a subcutaneously tunneledcentral catheter. These are all placed in the OR and removal requires a trip to the OR.
Appendix
Colonic irrigation with normal salineFor treatment of Hirschsprung’s Enterocololitis
ManagementFECES, solid or liquid, cannot be sterilized. Abnormalities of the colon, such as Hirschsprung’sDisease (HD) can lead to chronic constipation, megacolon, fecal stasis and eventually bacterialovergrowth and enterocolitis. If not treated promptly, and adequately, the infant/child withenterocolitis can rapidly deteriorate into septic shock. This may occur preoperatively in the proximalmegacolon or postoperatively in the pulled-through colon.
Mainstays of treatment of Hirschsprung’s enterocolitis are NPO, NGT, IVFs, and Metronidazole.
Always remember TUBES:
Nasogastric TUBE for gastric decompressionUrethral TUBE for monitoring urine outputCentral venous TUBE for rapid IV Fluid and Electrolyte resuscitationTrans-anal Colonic TUBE for Colonic Decompression/Irrigation
Colonic irrigation may be used in the hospital as part of the treatment of HD enterocolitis. It may alsobe used at home for patients with abdominal distention in the following circumstances:
Abdominal distension occurring 4-6 weeks post-pull through, AFTER BOWEL MOVEMENTSHAVE BEEN WELL ESTABLISED.
Colonic irrigation with normal saline solution Irrigations should only be initiated and continued under the direct supervision of the attendingsurgeon. Indications are abdominal distention due to retained liquid stool and air.
PreparationPrior to starting, evaluate for fecal impaction by digital rectal exam. If present, disimpaction undergeneral anesthesia may be necessary.
SuppliesSilicone Foley catheter the size of the child’s thumb (16 Fr. for children under one year of age toa maximum of 24 Fr. for children over one year of age). It may be necessary to put additionalholes on the side of the catheter. The Foley balloon is NEVER inflated. DO NOT USE REDRUBBER CATHETERS. They are too stiff and lumen is too small vis a vis the outside diameter.
Use a 60ml catheter tip syringe.Normal Saline (NS).2 basins (or equivalent) and a large plastic bucket.Water soluble lubricant
Standard Procedure1. Lubricate catheter and gently insert 10-12cm into the rectum (10cm for children less than 1 yr of
age and 12cm for children more than 1 yr of age).2. The tip of the catheter is in the right place when there is a gush of air/liquid stool through the
catheter.3. DO NOT INFLATE THE FOLEY BALLOON.4. Test the catheter position by pushing/pulling with the plunger of the syringe. Air should freely
move in and out of the syringe. If this does not occur, pull back on the catheter and test again untilair moves freely.
5. If air does not move freely, discontinue the procedure and consult with the attending physician.6. Fill the clean basin with NS.7. Aspirate 20 ml NS from the clean basin with the syringe and irrigate the catheter.8. Pull back on the plunger to allow the stool and saline to return. If there is no return flow,
disconnect the syringe from the catheter and allow fluid to drip into the dirty basin. If return flowis slow, remove the catheter, clear the holes of stool and reinsert the catheter.
9. If drainage is unsatisfactory, discontinue the procedure and consult with the attending physician. 10. If drainage is satisfactory, you may proceed.11. Repeat the process making sure the volume of fluid drained is greater than or equal to the volume
of fluid introduced. By the time the clean basin is empty of NS, the soiled basin should be filledwith an equivalent volume of effluent.
12. Refill clean basin with NS and empty dirty basin into the large plastic bucket. 13. Continue irrigation until return flow is clear.
This treatment may be repeated as ordered by the attending physician.

Nasogastric tubesSmallest sump tube is 6 Fr Replogle
6- 10 Fr for neonatesReplogle tube preferred in infants because the two holes are near the tip of the tubeThe air vent on the sump tube will reduce the likelihood of occlusion of the tube—commonproblem in small suction tubes
The approximate size of an NGT is the size of the child’s forefinger.
If a bigger tube is needed, insert an OGT The approximate size of an OGT is the size of the child’sthumb.
Gastrostomy TubesThere are many types of g-tubes
Low profileLie flush with the abdominal wall, need to be attached to a tube for feeds and drainageBard button and microvasive—no balloon Mic-key, Ross, AMT minibutton--inflates with a balloon
G tubes with outer tubesFoley catheter (cut off the rounded tip)Peg tube—flanged tubeMic tubes-inflatable balloon (5, 20 ml)Malecot - flanged tube (you will need a butterfly introducer; an anal fistula probe can also beused)
Guidelines for Replacing a G-tubeThe most important fact to know before replacing a G-tube is how long ago it was placed and ifplaced open, laparoscopically, or PEG (by Internist – possibility of bowel between the stomach andabdominal wall)
1. If the g-tube was placed 2 weeks to 2 months ago, tube can be replaced and a g tube study may benecessary.
2. If the g-tube was placed less than 2 weeks ago, notify senior resident/attending, tube may need tobe replaced operatively.
3. If there is any question after replacing a G-tube, obtain a G-tube study (use water soluble radio-opaque dye)
Leaking G-tubesLeaking G-tubes may be addressed as follows:
1. Place more fluid in the balloon.2. Secure G-tube in place with nipple or tape under a little tension. If these do not work call the
surgical nurse before doing #3.3. Replace with larger G-tube.4. Remove G-tube for 24 hrs, let tract close down, and then replace
The surgical nurse or attending should be consulted before attempting these maneuvers.

Muscle biopsy protocolMuscle biopsies are frequently performed by our service. Preferred sample size is 0.5 x 0.5 x 2 cm.Biopsies must be received by the pathology department before 4:30 pm on weekdays. Specimensshould be left on gauze which is dampened with saline and wrung out, then placed in a plastic screw-top specimen container with a label.
If muscle biopsy is needed for a neuro-muscular problem, biopsy should be done under localanaesthesia

Conditions & Procedures
Ovarian Cysts A. Etiology
1. Neonatal: Maternal hormonal stimulation in-utero can result in a cyst on the fetal ovary2. Prepubertal: enlargement of cystic follicle; rare because gonadotropin stimulation of the
ovary decreases in infancy and early childhood and increases with the onset of puberty3. Postpubertal: failure of the maturing follicle to ovulate and involute
B. Epidemiology 1. Uncommon between the neonatal period and puberty2. Common between menarche and 18 years of age
C. Clinical presentation1. Prenatal: prenatal ultrasound2. Neonatal: Pelvic mass 3. Prepubertal- can be hormonally active and result in precocious pseudopuberty (McCune-
Albright syndrome)- premature vaginal bleeding, abdominal mass or increasing abd girth,feeling of bloating or abd fullness, urinary retention or frequency
4. Postpubertal – can by asymptomatic or cause menstrual irregularities, pelvic pain, or if large,can cause constipation, urinary frequency, and pelvic heaviness
5. Rupture: intraabdominal pain and bleeding (range from minor to severe)D. Workup
1. Pelvic ultrasound2. Detailed menstrual and sexual history3. Pregnancy test4. CBC
E. Treatment1. If simple, small and detected as incidental finding can be observantly managed. 2. If they are symptomatic, greater than 3-5 cm in diameter, or have solid components or
septations, resection with ovarian sparing is initial surgical therapyF. Outcome
1. Pelvic ultrasound in 3 months with clinic appt2. No further follow-up needed
Ovarian TorsionA. Etiology
1. Can occur with ovarian cyst of any size and normal ovaries 2. since ovary descends to the true pelvis by puberty, the ovary is an abdominal organ
susceptible to torsion during the prepubertal periodB. Clinical presentation
1. Lower abd pain of sudden onset, nausea, vomiting, low grade fever, pallor, leukocytosis(with left shift), followed by less severe localized pain
2. several presentations of abd pain:3. chronic aching abdominal pain (periumbilical or lower quadrant) 4. acute severe pain simulating appendicitis or peritonitis 5. intermittent pain from intermittent torsion
C. Workup1. Pelvic ultrasound- size discrepancy in ovarian volumes with classic peripheralization of
follicles2. Doppler ultrasound – to eval blood flow to ovary 3. CT or MRI – have been used but value of these have not been established
D. Treatment1. Surgery at time of diagnosis to salvage ovary by untwisting vascular pedicle
E. Outcome/follow-up1. Ultrasound in 3 months with clinic appt2. No further follow up needed
CCAM/CPAM/SequestrationA. Type
1. Pulmonary sequestration – a non-communicating mass comprised of lung parenchyma, withinthe lung (intralobar) or outside of the lung (extralobar). May be found above, below or rarelywithin diaphragm. Distinguished by an abnormal arterial blood supply.
2. Congenital cystic adenomatoid malformation/congenital pulmonary airway malformation – asolid or cystic lung mass comprised of an overgrowth of bronchiolar tissue, immature alveoliand abnormal development of connective tissue and smooth muscle that does not functionnormally. Stratified into types I-IV.
B. Etiology - Uncertain but thought to be a congenital, not acquired, malformation of the foregutduring the first weeks of fetal development.
C. Epidemiology - Rare, approximately 1:30,000 live births.D. Associated Anomalies - May be found in patients with other anomalies such as Congenital
Diaphragmatic Hernia. E. Clinical presentation
1. Fetal diagnosis by ultrasound2. Patients are often asymptomatic3. Respiratory distress in the newborn period is possible but rare4. Pneumonia5. Asthma-like symptoms6. CHF for patients with large sequestration
F. Work up – CT scan of the chest with IV contrast performed between 3-6 months of life.G. Treatment
1. No intervention2. Surgical resection of mass - open or thoracoscopic
3. Hospital stay – approximately 72 hoursH. Outcome
1. Pathology results2. Annual follow up in LIFE clinic3. Non surgical outcomes may include: Pneumonia, asthma, malignant degeneration, CHF
possible with sequestration. 4. Postsurgical outcomes may include: Pneumonia, asthma, scoliosis, pectus deformities.
AppendicitisAppendicitis is by far the most common abdominal surgical problem in childhood. The diagnosis ofappendicitis can be quite difficult in children.
Intermittent abdominal pain turning to persistent; increasing in intensity; and epigastric painshifting to a specific quadrant, should make you suspect appendicitis.Localized and reproducible tenderness in a specific quadrant is the cardinal reliable sign ofappendicitis. Due to the rotation of the intestines in the fetus, the cecum and appendix may be inany of the 4 quadrants. Appendicitis may be accompanied by anorexia, nausea, and vomiting, but these are notdiscriminating signs. Conversely, a hungry child may mean it is not appendicitis. Diarrhea may bepresent with retrocecal appendicitis.The younger the patient, the more likely that rupture and peritonitis will be present on admission.Additional imaging by US or fine cut CT scan may be necessary.IV Zosyn should be initiated once the diagnosis is confirmed (use IV Gentamicin/Clindamycin ifallergic).(If allergic use Cipro/Flagyl)Be aware of appendicitis in any in patient admitted for another diagnosis who developsabdominal pain
Perforated Appendicitis Rare non-operative management dictated by surgeons

Inguinal herniaThe incarcerated inguinal hernia is a common emergency room/inpatient consultation. Incarceratedinguinal hernias occur most often in infants during the first year of life. Most, if not all, can bereduced manually, which obviates the need for emergency surgery.
Reduction techniquesOccasionally, holding the baby in very steep Trendelenburg reduces the hernia, due to the pull ofthe mesentery. The hernia will be nearly impossible to reduce in a crying child. If sedation is necessary, obtainassistance from the ER staff.Fingers of one hand should fix the internal ring while the other should put gentle ‘downwardtraction’ on mass and squeeze the contents (imagine squeezing out the contents of a sausage) untilit squirts back through the ring.In females, when the ovary is palpated in the sac, minimal manipulation can reduce it even if ithas been present for several days. It can be exceedingly difficult to distinguish between an ovaryand a lymph node unless the lymph node is lateral to the external ring.Emergency surgical intervention is required if the hernia cannot be reduced, or if there is post-reduction evidence of persistent intestinal obstruction, or nonviable bowel/testicle/ovary.It can be exceedingly difficult to distinguish between an incarcerated inguinal hernia and a cordhydrocele. Transillumination may help. A rectal exam will allow palpation of the inside of theabdominal wall at the level of the internal ring.
Foreign body in airway/esophagusGet a PA and lateral x-ray of the neck and chest
Position of coin on CXray/neck film tells location-esophagus or trachea
GI foreign bodiesCoins are the most common esophageal foreign body.If the coin is in the proximal to mid esophagus, it is removed in OR with esophagoscopy.If the coin is in stomach or intestine, generally, the FB will pass on its own.Frequently, patients with esophageal foreign bodies get discharged home from PACU postremoval.Patients with long-standing airway foreign bodies or copious airway secretions will stay in thehospital for observation.Difficult esophageal foreign body removals or esophageal dilations may require a bariumswallow- this is done at the discretion of the attending surgeon.
Check with attending about getting a CXR postoperatively on esophageal foreign bodies.
Airway foreign bodiesPeanuts are the most common airway foreign body.If foreign body in trachea and pt is talking and stable, pt goes to OR, NPO period will bediscussed with anesthesia team.If patient is not talking or in acute distress, perform Heimlich maneuver.Airway foreign bodies are generally admitted for observation.All airway foreign bodies should get CXR postoperatively.
Discharge parents should be instructed to bring the child back for the following:
High spiking feversS.O.B.Refusal to swallowSevere irritability
GERDGastroesophageal reflux disease is one of the most common consults. Patients need a UGI as the bareminimum for a workup of fundoplication. The UGI is not to determine reflux but to look for anatomicanomalies that may be contributing to reflux (e.g. pyloric stenosis, duodenal web, etc.).
Additionally, a pH probe is usually needed to assess the degree of reflux. This should be done off ofGI meds. Occasionally, in lieu of a pH probe, other tests may determine significant reflux. Abronchoalveolar lavage that shows lipid-laden macrophages is nearly pathognomonic for GERD.Tube feeds that have been marked with dye that shows up in tracheal aspirates may also be sufficientcause for a fundoplication. Additionally, a neurologically impaired child who needs a G-tube willfrequently require a fundoplication.
Laparoscopic fundoplication and G-tube A. Pre Op: obtain UGI with limited SBFT B. If the patient is in house: Check NPO guidelines C. Post-op orders laparoscopic nissen + G-tube
1. NPO, G-tube to straight drain overnightD. Start clears via GT bolus/drip feeds
1. POD #1 if patient is not distended 2. Begin tube feeds later on POD #1 with advancement to full feeds by next AM
E. Post-op orders, laparoscopic nissen1. Clears postoperatively if not distended2. Post-nissen diet POD # 2
Post fundoplication Diet (first 3 months post-op)A. 1st 2 weeks: liquids only
1. avoid carbonated beverages or gum 2. (pt may not be able to burp or vomit- do not allow carbonated beverages or gum until pt able
to burp) 3. ex: water, milk, milkshakes, soup, jello, pudding, pureed baby food, yogurt
B. 3rd and 4th weeks: soft foods1. ex: mashed potatoes, pasta, rice, bread, fish, crackers, cereal, ground beef, cheese, peanut
butterC. Next 2 months: can resume his or her normal diet with some exceptions
1. Avoid choking hazard foods: hotdogs, steak, chicken, pizza, nuts
Medscan stop reglan or ranitidine right after operationProton-pump inhibitor – continue for 1 week at ½ dose, then 1 more week at ¼ orig dose, thenstop
Other ordersNutrition consult G-tube teaching per surgical nurseGI referral for outpatient appointmentG-tube supplies for homeEmergency supplies need to be placed at bedside post-op: foleys (one same size fr as GT and onesmaller), lubricant, extra GT of same size, 5ml syringe, tape, blue Kelly clamp)MIC-Key GT and Malecot GT will be first changed 2 months post-op Hollister Drain tube Holder device PMM# 2078 or bottle nipple with tip cut off is used to holdmalecot GT in place.

2. Staging done on exploratory laparotomy except 4SF. Treatment
1. Surgery; In stage 4S, primary tumor (usually adrenal gland) is resected; no need to debulkliver mets.a. Resect if possible, otherwise biopsy and stageb. Debulking not beneficial initially (maybe considered after chemotherapy).
c. Definite role for “2nd look” resection after chemotherapy (need over 95% gross totalresection).

Dose Reduction
In the event that a subject has a potential expected or unanticipated side effect of the study
drug/placebo (such as irritability) but there is no indication to stop the study drug/placebo, theclinical site PI will have the option to reduce the dose of the study drug/placebo by 50%. The subjectwill then be monitored for improvement in these symptoms. If the symptoms improve within 48 hours,the subject will be maintained at the reduced dose for the remainder of the days planned for theoriginal dose, as well as for the duration of treatment with this dose according to the normal taperschedule. If symptoms do not improve/resolve, a further reduction by 50% of the new dose will beconsidered by the clinical site PI. If the symptoms persist beyond 48 hours and the clinical site PIjudges it necessary that the study drug/placebo be discontinued, the tapering and discontinuationprotocol will be followed.

“sandwich” layer) plexib. Lack of non-adrenergic, noncholinergic inhibitory fibers (NO)c. Failure of relaxation of involved segment down to the internal anal sphincter
(condensation of most distal circular muscle fibers of rectum)
B. Epidemiology1. Incidence: 1:4000 - 1:7000 live births2. Male:female = 4:1 (Long-segment M:F = 1:1)3. Siblings of female index cases have 360X more risk than general population4.

b. Absent in 20-30% of short segment HD in newborns; may be absent in long segment (Lcolon or total colonic) aganglionosis
c. Normal caliber colon in patient with distal obstruction (think total colon Hirschsprung’s -TCA)
d. Failure to evacuate barium on 24 hour delayed film – presumptive evidence of HD innewborns; in older children, may be due to psychogenic constipation
3. Anorectal manometrya. Failure of relaxation of internal sphincter with rectal distensionb. Not diagnostic in young infants
4. Rectal biopsya. Suction biopsy is a bedside procedure
1. Submucosal (Meissner’s plexus – H&E stain; acetylcholinesterase staining)2. Biopsy at least 2 cm above dentate line (“physiologic” aganglionosis <2cm)
b. Full-thickness biopsy is an operative procedure; Gold Standard1. For older infants and children
c. Evaluate for absence of ganglion cells (Auerbach’s plexus), hypertrophic nerves,and/or
increased acetylcholinesterase staining5. The absence of proof of ganglion cells is proof of the presence of Hirschsprung’s Disease.
F. Treatment1. Decompression after histologic diagnosis of HD

Commonly Used MedicationsNever guess the dose of medication for infants and children. Making an estimate based on adultdosages is dangerous.
A child’s dose is NOT half the adult dose.
Please refer to the Harriet Lane Handbook, the inpatient pharmacist or UCSF website (http://meds) toconfirm dosages. All medications are based on the weight of the patient; no ranges are to be utilizedfor pain medications. Medications must be ordered on a mg/kg basis with proper avoidance ofabbreviations (i.e. when in doubt spell it out).
Be very careful about decimal points.Check if mg/kg dose is per 24 hrs or per dose (and bid or q12hrs; tid or q8hrs; qid or q6hrs)Check if dose is PO or IV (sometimes oral meds are put in syringes to facilitate giving smallvolumes)
Emergency DrugsApproximate size of a child’s trachea is the size of the child’s small (5th) finger
Atropine 0.02 mg/kg/dose IVP
Min single dose = 0.1mgMax single dose children = 0.5mg, adolescents = 1mg)May repeat x 1 doseEndotracheal administration: 0.03 mg/kg
Flumazenil 0.01mg/kg/dose IVP
Max single dose = 0.2mg, Max TOTAL dose = 1mgMay repeat every 1 minDextrose 2-4ml/kg (1-2 grams/kg) D25W IVP over 5 minutesMax adult dose: 50-100ml (25-50 grams)
Naloxone 0.1mg/kg IVP (up to 20kg)
> 5 years or > 20kg give 2mg rapid IVPMay repeat every 2-3 minutesEndotracheal administration: double dose
Analgesics/Narcotics
Guide to Initial Management of New-Onset PainNot intended for use in neonates 0-28 days
Codeine is NOT a recommended pain medication.
Metabolism to the active form is inefficient, producing many side-effect-inducing metabolites.10% of patients lack the enzyme to metabolize codeine and thus get no analgesia1-2% of patients are ultra-rapid metabolizers, and may suffer severe opiate intoxication
Methadone and Fentanyl should only be used with attending guidance.

Key Principles of Pain ManagementFor OPIATE NAÏVE PATIENTS – Start with low initial doses and re-assess and adjustfrequentlyCarefully consider monitoring options and frequency of vital signsBe wary of OVERSEDATION when combining opiates with benzodiazepines, Benadryl®, orother opiatesUse MORE THAN ONE class of pain med for moderate to severe pain
Acetaminophen or NSAIDS can greatly reduce the amount of opiate neededFor patients with sustained pain, provide BOTH background pain control AND PRN forbreakthrough
Around-the-clock Tylenol or Ibuprofen may be adequateConsider scheduled ketorolac, tramadol or a long-acting opiates (non-opiate-naïve patients) forpatients with moderate to severe pain
When ordering multiple PRN medications, specify sequence of drugs (i.e. for mild pain vs.moderate pain) ALWAYS include non-pharmacological adjunctive treatments when possible
Child lifeExercise/physical activityWarm packs, massage, etc.Biofeedback (HeartMath®)Acupuncture and/or Acupressure
Address Sleep Disturbances, Anxiety, and Nausea
Patients who have these symptoms will experience pain more severely and require larger dosesof pain medicationsA large percentage of hospitalized children suffer major sleep disturbance. Consider:Limiting unnecessary nighttime interventions (vital signs, etc)Emphasizing environmental factors such as “lights out”, “TV off”, establishing bedtime and wakeup scheduleMelatonin (starting dose 0.5 – 3 mg enterally at bedtime, depending on age of patient)Anxiety and sleep disturbances are not the same. Benzodiazepines are useful for anxiety but NOTas sleep agents (they induce non-restful sleep).
When using opiates, proactively address opiate Side EffectsConstipation – Start a bowel regimen before constipation sets in; pay attention to stool pattern andescalate as needed. Start with Miralax® daily, increase to BID dosing as needed. If constipationpersists, add Senna. If refractory to other treatments, consider oral naloxone (see dosing below)
Itching – Benadryl is not the treatment for most opiate-induced itching. The itching associated withmorphine and dilaudid is not histamine-mediated. Consider switching opiates or starting a low dosenaloxone infusion (consult pain service and/or pharmacy).
Nausea – Common, particularly with morphine, dilaudid, and hydrocodone. Give oral opiates withfood if possible.
Sedation – This is a precursor to more severe problems. Consult attending and/or pain serviceimmediately and adjust medication regimen.
Hypoventilation – Pay attention to resting respiratory rate and quality of respirations. Lowrespiratory rate, even in awake patients, is a sign of opiate intoxication. Immediately consultattending and/or pain service.

Naloxone (Narcan®) DosingOpiate intoxication (oversedation)
1 – 5 mcg/kg/dose (0.001-0.005mg/kg) IV, repeat q2-3 min as needed. Doses at the high end of this range may lead to reversal of analgesia.
Respiratory Arrest (code blue)0.1mg/kg (max 2mg) IV or IM
NOTIFY ATTENDING IF NARCAN® IS GIVEN
Low dose naloxone infusion for itching0.25 – 2 mcg/kg/hr (start at 0.25mcg and titrate by0.5 mcg/kg/hr to max dose of 2 mcg/kg/hour).
Oral naloxone for severe constipationStart at 0.5-1 mg/dose PO q 6hr (not weight based) Titrate up as needed to max of 4mg PO q6hr.Seek assistance before dosing young infantsMonitor for reversal of analgesia
