Anaesthesia and intensive care
-
We present our approach to management of awake craniotomy for epilepsy surgery for an adolescent. The importance of patient selection and preoperative preparation is stressed. Anaesthetic management included regional scalp block and preincisional surgical infiltration of local anaesthetic and light sedation with propofol, fentanyl and midazolam. The patient remained responsive to voice for all but a small part of the procedure.

Randomized Controlled Trial Comparative Study Clinical TrialTracheal intubation without muscle relaxant--a technique using sevoflurane vital capacity induction and alfentanil.
This randomized controlled study examined intubating conditions and haemodynamic changes following sevoflurane nitrous oxide induction in four groups: three different doses of alfentanil compared with low-dose alfentanil and suxamethonium. All patients received atropine 0.3 mg i.v. before induction of anaesthesia with vital capacity breaths of sevoflurane 8% (more than 7% in the inspiratory gas) in 60% nitrous oxide and oxygen. Patients were allocated randomly to four groups of intravenous supplements: group SA20, alfentanil 20 microg x kg(-1); group SA25, alfentanil 25 microg x kg(-1); group SA30, alfentanil 30 microg x kg(-1); group SSA, alfentanil 10 microg x kg(-1) and suxamethonium 1 mg x kg(-1). ⋯ Mean arterial pressure decreased significantly and similarly after induction in all groups. Two minutes after intubation the mean arterial pressure was increased significantly (P<0.05) compared to the post-induction value in group SSA. The intubating conditions obtained with sevoflurane plus alfentanil 30 microg x kg(-1) were comparable to those provided by the sevoflurane, suxamethonium and alfentanil 10 microg x kg(-1) combination.
