Pregnancy – L&D

Two Patients

  • Any time after 24 wks gestation needs assessment/monitoring of fetus as well as the mother
  • This includes continue monitoring of the fetus

Late Bleeding

  • DDx Previa vs abruption
  • US to localize placenta
  • No cervical exam until previa ruled out
  • Large bore access, transfusion, DIC labs

Labor and Delivery

  • Need sterile exam cervical check to evaluate stage of labor
  • Presentation – occipital fontanelle has 3 suture lines extending vs anterior fontanelle which has 4
  • After full dilation (10 cm) probably not ok to transfer b/c delivery imminent in next 20-60 min
  • Late and variable decels are signs of fetal distress
  • Feel for cord as the head is delivered and reduce over head if needed
  • Pull down to deliver anterior shoulder then up to deliver posterior shoulder

Shoulder Dystocia

  • Push mom’s legs back to extreme lithotomy (McRoberts)
  • Suprapubic pressure
  • Roll to hands and knees position
  • Rotational maneuvers
    • Put fingers behind the anterior shoulder and push forward
  • Deliver posterior arm
    • Get under the posterior arm and sweep it up in front of the face

Breech

  • Let the butt deliver without pulling in order to facilitate dilating the cervix
  • Rotate body so butt is facing the sky
  • Put fingers along babies chin/maxilla and control head to not allow neck extension while delivering the body and applying suprapubic pressure
  • Important thing to avoid is neck hyperextension or flexion

Cord

  • Delay clamping for 1 min in babies not requiring resus
  • Clamp 4-5 cm from baby’s abdomen and cut

Post Partum Hemorrhage

  • >500 ml in the 1st hr after delivery = PPH
  • Oxytocin 40 units in 1 L at 500 ml/hr
  • Misoprostol 800-1000 mcg rectal
  • TXA – 1 gm over 10 min
  • Methylergonovine 0.2 mg IM
  • Carboprost 0.25 mg IM q 15 min to 2 mg max
  • Can sweep the uterus
  • Bakri Balloon – Inflate w/ saline start with 250-500 ml but can accomodate up to 800 ml
  • Blakemore tube – Max volume ~ 500 ml

Resus C-section

  • Within 4 minutes of arrest is best
  • Vertical midline incision
  • Open uterus with scalpel and then midline incision with scissors
