Bartholin Gland Abscess I&D

Rapid Review

  • Background
    • Common techniques for incision and drainage of bartholin gland abscesses include marsupialization and fistulization with word catheter
  • Indications
    • Symptomatic abscesses that are at least 1 cm in diameter
  • Contraindications
    • No absolute contraindications. Relative contraindications include complex abscesses requiring general anesthesia.
  • Complications
    • Recurrence (30%), bleeding, infection.

Pearls

  • Keep the incision posterior to the labia minora to prevent any noticeable scarring.
  • Word catheterโ€™s can be inserted after drainage to reduce the rates of recurrence, though they will need to stay in for at least 2-4 weeks. Keep the initial incision small so that the Word catheter does not fall out.

Normal Spontaneous Vaginal Delivery

Rapid Review

  • Background
    • Uncomplicated, vaginal delivery of full-term (37-42 week) newborn. Represents the majority of births across the world.
  • Indications
    • Spontaneous labor mediated by hormone cascade or induction; rupture of amniotic/chorionic membranes.
  • Contraindications
    • Prolapsed cord, face/breech presentation, abnormal fetal heart patterns (bradycardia/tachycardia)
  • Complications
    • Premature rupture of membranes, failure to progress, postpartum hemorrhage

Pearls

  • Once the head presents itself, check immediately for a nuchal cord and reduce as needed. If unable to pull the cord over the infantโ€™s head, clamp/cut the cord once the infantโ€™s face is cleared from the perineum. 
  • Newborns can be very slippery post-delivery. Hold them close to your body to avoid dropping them. Do not clamp the umbilical cord until at least 30-60 seconds after delivery.

Pelvic Exam

Rapid Review

  • Background
    • Speculum examination of the vaginal walls and cervix, as well as a bimanual examination to evaluate the cervical os and evaluate for adnexal masses 
  • Indications
    • Vaginal bleeding (if hemodynamically unstable)
    • Acute urinary retention (evaluate for prolapsed organ)
  • Contraindications
    • Lack of consent
  • Complications:
    • Anxiety, pain

Pearls

  • Pelvic exams can be extremely uncomfortable for women, especially if they have any history of sexual assault. Go slow, communicate, and consider pre-treatment with a short-acting benzodiazepine for anxiolysis if needed.
  • If you donโ€™t have a bed with foot rests, rotate the speculum handle towards the ceiling instead of the floor.

Resuscitative Hysterotomy

Rapid Review

  • Background
    • Previously known as โ€œperimortem cesarean sectionโ€. Involves delivering a fetus from a gravid mother through an abdominal incision during or after maternal cardiopulmonary arrest. Potentially life-saving for both the mother and the fetus.
  • Indications
    • Maternal cardiac arrest w/o ROSC within 4 minutes
  • Contraindications
    • Gestational age < 24 weeks, ROSC within 4 minutes
  • Complications
    • Fetal injury, hemorrhagic shock

Pearls

  • Chest compressions should continue during this procedure as long as it can be accomplished safely.
  • If the placenta is encountered when entering the uterus, incise through it.

Shoulder Dystocia Management

Rapid Review

  • Background
    • Shoulder dystocia occurs when one or both shoulders become impacted against the bones of the maternal pelvis, preventing vaginal delivery. Management techniques include the McRobertโ€™s, Rubin, Jacquemier, and Woods maneuvers.
  • Indications
    • Any clinically significant shoulder dystocia
  • Contraindications
    • Fundal pressure, strong lateral traction, and head rotation beyond 90 degrees should be avoided.
  • Complications
    • Clavicle fracture, brachial plexus injury

Pearls

  • For a step-wise approach to shoulder dystocia, you can use the โ€œALARMERโ€ mnemonic (Ask for help, Legs to chest, Anterior shoulder disimpaction by suprapubic pressure, Release posterior shoulder, Maneuver of wood, Episiotomy, Roll on all fours)
  • If conservative measures fail, fracture the babyโ€™s clavicles with direct pressure over the middle of the clavicle to facilitate easier passage.
