AbstractAlthough postoperative nausea and vomiting and pain after supra- and infratentorial craniotomy have been evaluated in multiple studies, there are few data regarding pain or postoperative nausea and vomiting after transsphenoidal procedures. Therefore, we reviewed the perioperative records of 877 patients undergoing transsphenoidal surgery by the same surgeon. The overall incidence of postoperative emesis was 7.5%, significantly less than most studies of neurosurgical patients. An intraoperative cerebrospinal fluid leak and subsequent fat grafting, the use of lumbar intrathecal catheter, and patients presenting for the resection of a craniopharyngiomas all had a significantly increased incidence of postoperative emesis (11.4%, 17.1%, and 18%, respectively). Interestingly, antiemetic prophylaxis did not decrease the risk of vomiting overall or in any cohort of patients; however, both droperidol and ondansetron decreased the incidence of nausea in the postanesthesia care unit (PACU). Regarding pain and morphine consumption, patients who later developed diabetes insipidus had a significant increase in morphine requirements in the PACU. No other disease state was associated with increased pain or morphine consumption in the PACU.
