Context: Awake craniotomy is increasingly performed the world over. We share our experience of performing craniotomy awake with our anesthetic protocol. Aims: To evaluate and analyze the anesthesia records of the patients who underwent awake craniotomy at our institution. Settings and Design: University teaching hospital, Retrospective study. Materials and Methods: We reviewed records of the 42 consecutive patients who underwent awake craniotomy under conscious sedation using Fentanyl and

All patients received scalp blocks with a mixture of bupivacaine and lignocaine with adrenaline. Haloperidol and ondansetron were administered in all patients at induction of anesthesia. Results: All patients completed the procedure. One patient each needed endotracheal intubation and LMA for airway control during closure, while another required CPAP perioperatively because of desaturation to <80%. There was signiÞ cantly decreased use of anesthetics (P<0.001) and a trend towards reduction in complications (e.g. respiratory depression and deep sedation) (P>0.05) with the use of BIS as compared to without BIS. Intraoperative complications were hypertension (19%), tight brain (14.2%), focal seizure (9.5%) respiratory depression (7.1%), deep sedation (7.1%), tachycardia (7.1%) and bradycardia. Two patients desaturated to <95%. 23.8% patients developed transient neurological deÞ cits. The most frequent postoperative complications were PONV (19%) and seizures (16.6%). Conclusions: With the use of advanced monitoring and newer anesthetics, awake craniotomy is a relatively safe procedure with an accepted rate of complications.
