Incidence of postoperative nausea and vomiting following neurosurgical procedures in postanesthesia care unit

Abstract

Objective To study the incidence of postoperative nausea and vomiting(PONV) after different neurosurgical procedures in the postanesthesia care unit (PACU).Methods 5 078 adult patients who had undergone neurosurgical procedures enrolled into PACU were divided nine groups.The incidence of PONV were recorded and treated.Results The overall incidence of PONV following neurosurgical procedures was 15.7％.The incidence of PONV in patients undergoing craniopharyngioma、ventricular tumor、infratentorial craniotomy、intracranial aneurysm and arteriovenous malformation、supratentorial tumor、epilepsy、transsphenoidal surgery of pituitary tumor、spinal cord tumor and others was 28.4％ 、26.7％、24.2％ 、20.8％、19.3％、15.8％、8.9％、8.4％ and 7.5％,respectively.Conclusions The overall incidence of PONV in PACU following neurosurgical procedures is approximately 16％.The incidence of PONV following neurusurgical procedures is different and craniopharyngioma、ventricular tumor and posterior fossa tumor are high risk factors for PONV.Strategies for the prevention of PONV following neurusurgical procedures are required.
