The Effects of Scalp Block With Bupivacaine Versus Levobupivacaine

Summary

Ninety American Society of Anesthesiologists (ASA) Physical Status classification system I-II patients were recruited for a randomised, placebo-controlled, double-blind study and were randomly divided into three groups to receive either 20 ml of 0.5% bupivacaine (Group B; n=30), 20 ml of 0.5% levobupivacaine (Group L; n=30) or saline as a placebo (Group C; n=30). Scalp block was performed 5 min before head pinning. The primary outcome of the study was mean arterial pressure (MAP) and secondary outcomes were heart rate (HR), visual analogue scale (VAS) scores, additional intraoperative and postoperative drug use. Postoperative pain was evaluated using a 10-cm visual analogue scale (VAS).
