Anesthetic management of conjoined twins undergoing one-stage surgical separation: A single center experience

Objective: to summarize our experience in the anesthetic management of conjoined twins undergoing one-stage surgical separation. methodology: medical records of conjoined twins admitted to our hospital for treatment and considered for surgical separation from 1996 to present were retrospectively reviewed. four cases of conjoined twins underwent one-stage surgical separation under general anesthesia. preoperative evaluation was performed to determine the extent of anatomical conjunction and associated anomalies. anesthesia was simultaneously induced in all conjoined twins. the intubation procedure was successfully performed with the head slightly rotated to each baby’s side, followed by the administration of vecuronium. anesthetic agents were administered according to the estimated weight of each baby. one case of conjoined twins underwent surgical separation with cardiopulmonary bypass due to shared hearts. results: all conjoined twins were successfully separated. no significant respiratory or cardiac events occurred during surgery except for one twin, which died after separation because of complicated congenital heart disease. conclusions: accurate preoperative evaluation, respiratory and circulatory management, and close cooperation of the multidisciplinary team are important aspects of anesthetic management of conjoined twins surgery.
