– However, injuries to adjacent structures may cause ileus

» Ribs, pelvis, spine

– Percussion

• Pain with slight mov’t of ABD wall = peritonitis

• Tympanic Sound = Free Air

• Dull Sound = Hemoperitoneum

1/00 59

Initial Evaluation

• Physical Exam

Blunt Abdominal Trauma

• Most Commonly Injured Organs

1. Spleen

2. Liver

3. Small Intestine

4. Large Intestine

• Two Primary Mechanisms

– Compression

– Deceleration

1/00 64


• Compression Injury

– Result from direct blows or external compressionagainst a fixed object (lap belt, spinal column).

– Subcapsular Hematomas to Solid Organs

• Caused by small tears

• Most common injury

– Hollow Organ Rupture

• Transient pressure ↑ = Intraluminal Pressure ↑ = Rupture

1/00 65


• Deceleration Injury

– Result from a differential movement of fixed andnon-fixed parts of the body.

– Tears occur @ Junction of Support Structures

• Ligamentum Teres = Liver Laceration

• Mesentery of Bowel = Mesenteric Tear

• Retroperitoneum = Renal Artery Laceration

1/00 66


• Pre-Hospital Management

– ABC’s

– IV Access

• 2 Large Bore peripheral IV (if possible)

• Never delay transport for IV Access

– IVF Crystalloid Resuscitation

• Titrate Volume to Patient’s Clinical Response (VS)

• Goal BP Mgt = SBP 90-100

• Be Wary of Over Resuscitation = Hemodilution

1/00 67



– Prolonged Transport Times & Hypotension

• May be role for Pneumatic Anti-Shock Garments

• Especially in case of Pelvic Fracture & Shock

• Remember…More fluids may not be the answer– These Patients need definitive treatment at a Hospital

1/00 73

Shock Classification

• Class I Hemorrhage (loss of 0-15%)

– Minimal Tachycardia

– No BP change

• Class II Hemorrhage (loss of 15-30%)

– Tachycardia

– Delayed cap refill

– Cool clammy skin

– Anxiety

1/00 74


• Class III Hemorrhage (loss of 30-40%)

– Marked Tachycardia

– Marked Tachypnea

– Hypotension

– Change Mental Status

– Agitation &/or Anxiety

1/00 75


• Class IV Hemorrahge (loss of >40%)

– Marked Tachycardia

– Marked Tachypnea

– Hypotension

– Narrow Pulse Pressure

• Or immeasurable diastolic BP

– Cold/Pale skin

– Change in MS or Unconscious

1/00 76


• Caveat:

– Compensatory mechanisms prevent Hypotension

• So look for Tachycardia

– Patients on B-blockers will not be Tachycardic!!

– Elderly patients may not Compensate well

• ie. HR

1/00 77


• GSW

– Missile with high-energy transfer

– Unpredictable extent of intra-abdominal injury

• Missile track

• Secondary missiles– Bullet fragments

– Bone fragments

• Stab Wounds

– More predictable regarding injured organs

1/00 78



– ABC’s

– IV Access

• 2 Large Bore peripheral IV (if possible)

• Never delay transport for IV Access

– IVF Crystalloid Resuscitation

• Titrate Volume to Patient’s Clinical Response (VS)

• Goal BP Mgt = SBP 90-100

1/00 79



– Do not remove impaled objects or probe wounds

– Patients should be delivered to Level I or next bestfacility

– As always, unstable patients should go to closest ED

Wound Ballistics

• Wound Ballistics

– A very mystifying and often factitious specialty

– Often entangles terms such as “projectile-tissueinteractions” and “stopping power”

– Tough field to study, because not many people arevolunteering to be shot in the name of “science”

1/00 81

Wound Ballistics

• Simplest Convention(for me)

“Bullet Velocity”

Velocity to:

Penetrate Skin = 163 fps

Break Bone = 213 fps

** Other factors are important**

Popular Weaponry

9mm = 1155 fps

.357 magnum = 1450 fps

AK-47 = 2400 fps

– Trauma is leading cause of Morbidity & Mortality inpediatric population

– Abdominal Trauma associated with 8.5% Mortalityrate

– 8-10% of all Trauma admissions in children

1/00 84


• Pathophysiology

– Unique Anatomy to Pediatric Patients

• Thinner musculature & padding = less protection

• Ribs are more flexible = less dissipation of energy

• Solid organs are comparatively larger than adult

• Kidney more mobile = more commonly injured

• Duodenal Hematoma

– Classic Case:

• Kid falls off bike and strikes abdomen on end ofhandlebar…complaining continuing pain after

– Duodenum

• Located in mid-epigastric reagion

• Fixed portion of bowel to retroperitoneum

– Medical Issue

• Hematoma can cause obstruction

• Worst case = Hematoma leads to bowl wall necrosis

1/00 87


• Spleen Rupture

– Commonly Seen:

• Blunt Trauma to LUQ/Flank

• Football Players, Snowboarder/Skier

– Why so High Risk?

• Anatomic Position (with ribs overlaying)

• Thin Capsule

• Predisposition– Mononucleosis, Malaria, etc. lead to Splenomegaly

1/00 94

Blood products include:

Red blood cells:

• Blood bank

• Autologous (cell saver)

• Whole blood

• Fresh frozen plasma

• Platelets

• Fibrinogen concentrate/cryoprecipitate

1/00 95

Managing Blood Loss ThroughTransfusion

Always ask:

• Is fluid resuscitation indicated?

• Is the patient hemodynamically stable?

1/00 96

Fluid Resuscitation Goals

Within the first 24 hours, fluids must be provided untilacidosisis under control:

• Lactate <2.5 mmol/L or

• Base deficit <2

Targets for blood tests:

• Hemoglobin >8 and <10 g/dL

• INR <1.5, PT <16 seconds, APTT <30 seconds

• Fibrinogen >1 g/L

• Platelets >50 x 109/L

1/00 97

Hemodynamic Stability:The 90 mmHg Cutoff

Patients are hemodynamically unstable if

• SBP <90 mmHg or

• Maintaining SBP >90 mmHg requires massivefluids or vasopressor support

Patients are hemodynamically stable if

• SBP >90 mmHg for 1 hour without thesemeasures

• SaO2 ≤90% or PaO2 <60 mmHg at oxygensupplementation

• Respiratory rate >35 breaths per minute

• Respiratory distress (defined as marked use ofaccessory muscles or paradoxical breathing)

Goals Of Ventilator Management AndWeaning Guidelines

1. Ensure low tidal volumes (Vt) are used:

• Limiting ventilation volumes (Vt) to 6 ±2 mL/kg PBW

2. Provide a lung-protective strategy for all ventilated patients:

• Limiting plateau airway pressures to ≤30 cm H2O wheneverpossible

3. Provide guidelines for the use of positive end-expiratorypressure (PEEP):

• Decreasing PEEP and FiO2 as early as possible givenoxygenation guidelines to move to spontaneous breathing trial(SBT) as soonas possible

Goals Of Ventilator Management AndWeaning Guidelines

4. Ensure extubation or discontinuation ofmechanical ventilation at earliest possible time:

• Attempting to wean on an ongoing basis, atleast once daily when weaning criteria met

5. Avoid the use of muscle relaxants, exceptwhere specifically indicated.

Predicted Body Weight

PBW calculated as follows:

• For males: PBW (kg) = 50 + .91 [height (cm) –152.4]

• For females: PBW (kg) = 45.5 + .91 [height (cm)– 152.4]

Initiating Ventilator Procedures:

Oxygenation goal:

• PaO2 55–80 mmHg or

• SpO2 88–95%

PEEP:

• Must be <35 cm H2O

• Percent O2/PEEP ratio should be = 5±1

Example: FiO2 0.50; PEEP 12 (50/12 = 4.1)

Continuing Ventilator Management:pH Guidelines

Adjust for pH goal 7.25–7.45 (if possible):

• Use resp rate (RR) if possible (≤35/min):

• Keep PaCO2 ≥25 mmHg

• Bicarb infusion can be given at discretion ofbedside physician

• If pH ≤7.15, then Vt can be increased by 1mL/kg to achieve pH >7.15, and target plateaupressure (Pplat) may be exceeded
