Gender Rather Than Choice of Intermediate Duration Opioids Affects Emergence After Craniotomy for Large Intracranial Tumors

摘要

Background:Opioid-based anesthetic techniques are commonly used during neurosurgical procedures. In the present randomized prospective study, we studied emergence after 4 anesthetic regimens combining intermediate duration opioids with isoflurane and nitrous oxide (N2O), in patients undergoing craniotomy for large (> 30 mm diameter with intracranial mass effect) intracranial tumors.
