Labor DystociaDifficult Labor: prolonged or abnormal labor Problem with Four Ps: Passage, Passenger, Power, Psyche

Risks Related to Labor DystociaMaternal- Infection - Exhaustion - Dehydration - Ketosis - Lacerations - Hemorrhage perfusion Psychological trauma

Fetal- Infection - Asphyxia - Cord prolapse - Insufficient - Placental - Shoulder dystocia - Birth trauma

Labor DystociaProlonged Latent Phase: > 20 hrs in nullip; > 14 hrs in multip.

Protracted Active Phase: < 1.2 cm dilation q hr in nullip.; < 1. 5 cm. q h multip

Active Phase Arrest: No cervical change in 2 - 4 hours

Aberrant Fetal Descent Patterns: > 1 - 2 cm descent / hour

Prolonged 2nd Stage: > 3 hrs in nullip; > 2 hrs inmultip.

Precipitous Labor: < 3 hours

Labor DystociaProblem with Powers Abnormal Uterine Contraction Pattern Hypertonic Contractions Hypotonic Contractions Precipitous Labor and Birth

Labor DystociaProblem with Passage Pelvic Contracture Non-Gynecoid Pelvis.

Problem with Passenger Malpresentation Macrosomia Fetal Anomalies

Management of Labor DystociaAugmentation of Labor Amniotomy Oxytocin Augmentation

Assisted and Operative Delivery Vacuum - Assisted Delivery Forceps Delivery Cesarean Birth

Induction or Augmentation of LaborProstaglandin E2 for cervical ripening

Amniotomy artificial rupture of membranes

Oxytocin (Pitocin) induction of uterine contractions

Cytotec Controversy

Induction or Augmentation of LaborRequires Maternal or Fetal Indication Favorable Cervix Bishop Score 5 or greater

Necessary Equipment/Supplies EFM (Toco & US) Mainline IV Start Pitocin IV Solution (10 - 20 U / L) Infusion Pump Terbutaline Rx

Induction or Augmentation of LaborBishop ScoreEvaluation of Readiness for Labor 0 1 2 Dilatation (cm) 0 1-2 3-4 Effacement (%) 0-30 40-50 60-70 Station -3 -2 -1,0 +1 Cervical Firm Med. Soft Consistency Cervical Position Post. ML Ant 3 5-6 80+

Augmentation of LaborPitocin Induction: Informed consent Discuss with family. Mainline IV Continuous maternal toco. Continuous fetal monitoring IV Solution: LR or D5LR with 10 - 20 Units pitocin Start Pitocin drip at 1 mu/ min per infusion pump. May increase every 20 - 60 minutes

Assisted and Operative DeliveryVacuum - Assisted Delivery Mechanism: Suction and Traction used to assistdelivery of presenting part.

Indication: Most commonly related to prolonged2nd Stage of Labor. Takes up less space and causes less injury that forceps. (CPD); Most malpresentations and malpositions; extreme prematurity.

Contraindications: Cephalopelvic Disproportion Nursing Responsibility: FHR checks q 5 minutes;Hand held suction pump. Pressure release between UCs; Assess neonatal head for caput resolution after delivery.

Assisted and Operative DeliveryForceps Delivery Mechanism: Traction and rotation of fetalpresenting part with curved metal tongs.

Indication: Prolonged 2nd stage (> 3 hrs); maternal Contraindications: Cephalopelvic Disproportion(CPD); Most malpresentations and malpositions; < +2 station.

exhaustion; Outlet: > +2 station and visible at vaginal introitus; low: > +2, but not visible.

Disadvantages: Maternal and fetal trama. Nursing Responsibility: FHR checks q 5 minutes;obtain forceps; assess neonate and mother for trauma. Increased legal liability.

Cesarean Birth25% of all births in U.S. Indication For Cesarean Birth Unsafe vaginal birth r/t maternal or fetal factors.

Complications Infection Pain GI Dysfunction Bladder Injury Coagulopathy Risks r/t Anesthesia (Epidural vs General) Psychological Trauma Risk to Maternal/ Infant Attachment

Cesarean BirthTypes of Cesarean Incisions Lower Uterine Segment (Low Transverse) Classical (Vertical Midline)Only L. Uterine Segment Cesareans allow a trial of labor with the next pregnancy. Classical is used for emergency Cesareans or for some mal presentations.

Pre-0p Activities and Prep Ethical/ Legal Issues

Anesthesia for Cesarean BirthEpidural Anesthesia Spinal Anesthesia General Anesthesia

Epidural Anesthesia for CesareanMechanism: Variety of Caine drugs administered in theepidural space at L-2 to L-4 with a T-8 to S-5 block

Nursing Responsibilities: Informed Consent Pre-hydration by IV bolus Assisting Anesthesiology with placement Comfort the patient. Monitor maternal / /fetal physiologic response including level of anesthesia.

Contraindications: Clotting disorders, agent allergies, hx ofspinal injuries

Adverse Effect: Maternal Hypotension; Inadvertent Spinal or systemic administration; Incomplete pain relief.

Spinal Anesthesia for CesareanMechanism: Variety of Caine drugs administered in thesubarachnoid space at L-3 to L-4 a block up to T-6.

Nursing Responsibilities: Informed Consent Pre-hydration by IV bolus Assist anesthesiology with positioning patient Comfort to patient. Monitor maternal / /fetal physiologic response including level of anesthesia. Protect from injury.

Contraindications: Clotting disorders, agent allergies, hxof spinal injuries; meningitis.

Adverse Effect: Maternal Hypotension; Inadvertent Spinal or systemic administration; Incomplete pain relief.

General Anesthesia for CesareanMechanism: Inhalation anesthesia such as nitrous oxide incombination with an IV short-acting barbiturate, such as thiopental sodium, rendering patient unconscious.

Nursing Responsibilities: Informed Consent Pre-hydration by IV bolus Assisting anesthesiology with cricoid pressure for intubation Circulation Nurse for the Cesarean.

Contraindications: Allergies, fetal compromise Adverse Effect: Neonatal respiratory depression Maternal response to general anesthesia

Case Study: Augmentation of LaborS/ O: 24 y.o. G1 P0 with ruptured membranes x 17hours. Normal Pregnancy. EFW: 8 1/2 lbs.. Cervix on admission: 2cm, 50% effaced, -1 station, ROM in elevator. Reports UCs x 2 hours
