Uterine Inversion
Considerations
-
Emergency situation
-
Postpartum hemorrhage with need for massive transfusion
-
Facilitation of uterine reduction: tocolytics (nitroglycerin, volatile anesthetics)
-
Treatment of uterine atony after reduction (medical & surgical)
-
Pregnancy considerations (difficult intubation, aspiration, ↓ time to desaturation, aortocaval compression, 2 patients)
Goals & Conflicts
-
RSI in the setting of a patient in hypovolemic shock
-
Safely manage airway avoiding aspiration & hypoxemia
-
Aggressive fluid resuscitation
-
Close communication with obstetrician during titration of tocolytic therapy
Management
-
Confirm diagnosis: postpartum hemorrhage, hypovolemic shock, mass in introitus/vagina
-
Mobilize resources, obstetrician STAT, establish management plan:
-
To OR for definitive treatment
-
Assemble skilled help
-
Notify blood bank, prepare for massive transfusion
-
-
Begin fluid resuscitation, large bore IV access, rapid transfuser, blood products to OR
-
Tocolytic therapy: nitroglycerin 100-400 mcg IV boluses (chase with phenylephrine boluses), volatile anesthesia following RSI (low dose or no ketamine)
-
Followed by uterotonic therapy:
-
Oxytocin 40 units per 1 L crystalloid or duratocin 100mcg IV slow push
-
Ergonovine 0.2mg IM & 0.2mg IV slow push
-
Carboprost (hemabate) 0.25mg IM or intramyometrial
-
Misoprostol 800-1200mcg rectal
-
