Anaphylactoid shock induced by oxytocin administration--a case report.

"Piton-S", a preparation of synthetic hormone of oxytocin, is the most common pharmacologic agent used for the induction and augmentation of labor, as well as preventing postpartum hemorrhage owing to its uterotonic properties. There are many adverse effects reported with oxytocin, including hypotension and tachycardia. Anaphylactoid reaction to oxytocin is extremely rare. Here we bring forth a case who sustained from anaphylactoid shock following oxytocin administration during the act of cesarean section. We would like to discuss the proper management of perioperative anaphylaxis after review of similar cases in the literature.
