Summary

In this study, the investigators hypothesize that preemptive scalp block in neurosurgical patients may decrease incidence of PONV after craniotomy through decreasing intraoperative inhalational agents' concentration and decreasing intraoperative opioids requirements, with better intraoperative hemodynamics and lesser recovery time

Description

Patients will be recruited after admission to the hospital for surgery. Randomization will be performed using computer-generated random number tables in opaque sealed envelopes prepared by an anesthesiologist who will be not part of the study

Patients will be randomly divided into two groups using a computer generated random number chart. Group S received scalp block with 20 ml of 0.5% bupivacaine, whereas Group C received scalp block using 20 mL normal saline and will be considered as control group.
