A previously healthy 29-year-old woman has the sudden onset of dyspnea and becomes unresponsive after the vaginal delivery of a male newborn who weighs 3570 g (7 lb 14 oz). Pregnancy was uneventful. Oxytocin was administered during labor to augment contractions. Examination shows no pulse and no spontaneous respirations. Which of the following is the most likely diagnosis?

A. Acute myocardial infarction
B. Amniotic fluid embolism
C. Eclampsia
D. Hemorrhagic cerebral stroke
E. Oxytocin overdose

My first guess was B. But after some research, i think E is also likely?:

"OXYTOCIN: Consider the information the doctor receives regarding the risks of Oxytocin. The manufacturer of Oxytocin warns the provider in the package insert:

"Maternal deaths due to hypertensive episodes, subarachnoid hemorrhage, rupture of the uterus, fetal deaths and permanent CNS or brain damage of the infant due to various causes have been reported to be associated with the use of parenteral oxytocic drugs for induction of labor or for augmentation in the first and second stages of labor."

In addition to the more benign effects of uterine stimulants, such as nausea and vomiting, the American manufacturer of Pitocin (Oxytocin) points out in its package insert that Oxytocin can cause:

(a) maternal hypertensive episodes

(b) subarachnoid hemorrhage

(c) anaphylactic reaction

(d) postpartum hemorrhage

(e) cardiac arrhythmias

(f) fatal afibrinogenemia

(g) premature ventricular contraction

(h) pelvic hematoma

(i) uterine hypertonicity

(j) uterine spasm

(k) tetanic contractions

(l) uterine rupture

(m) increased blood loss

(n) convulsions

(o) coma

(p) fatal induced-induced water intoxication

The following adverse effects of maternally administered Oxytocin have been reported in the fetus or infant:

(a) bradycardia

(b) premature ventricular contractions and other arrhythmias

(c) low 5 minute Apgar scores

(d) neonatal jaundice

(e) neonatal retinal hemorrhage

(f) permanent central nervous system or brain damage

(d) fetal death"
