Randomized Controlled Trial Comparative Study Clinical TrialA randomized, double-blind comparison of ondansetron versus placebo for prevention of nausea and vomiting after infratentorial craniotomy.
Ondansetron was compared with placebo for nausea and vomiting prophylaxis after fentanyl/isoflurane/relaxant anesthesia and infratentorial craniotomy. Eight milligrams intravenous ondansetron or vehicle was administered at skin closure. Nausea, emesis, and antiemetic use were recorded at 0, 0.5, 1, 4, 8, 12, 24, and 48 hours. ⋯ Nausea and vomiting are frequent and protracted after infratentorial craniotomy. Administration of single-dose ondansetron (8 mg intravenously) at wound closure was partially effective in reducing acute nausea and vomiting but had little delayed benefit. Scheduled prophylactic administration of antiemetic therapy during the first 48 hours after infratentorial craniotomy should be evaluated for efficacy and safety.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain management after supratentorial craniotomy.
The aim of this study was to compare the analgesic efficacy of three different postoperative treatments after supratentorial craniotomy. Sixty-four patients were allocated prospectively and randomly into three groups: paracetamol (the P group, n = 8), paracetamol and tramadol (the PT group, n = 29), and paracetamol and nalbuphine (the PN group, n = 27). General anesthesia was standardized with propofol and remifentanil using atracurium as the muscle relaxant. ⋯ More cases of nausea and vomiting were observed in the PT group but the difference was not significant (P < .06). In conclusion, pain after supratentorial neurosurgery must be taken into account, and paracetamol alone is insufficient in bringing relief to the patient. Addition of either tramadol or nalbuphine to paracetamol seems necessary to achieve adequate analgesia, with, nevertheless, a larger dose of tramadol to fulfill this objective.
