Effect of Scalp Block on Intraoperative Hemodynamics and Postoperative Pain in Craniotomy Patients"

The goal of this clinical trial is to learn if an ultrasound-guided scalp block can improve intraoperative hemodynamic stability and provide better postoperative pain relief in adult patients undergoing elective supratentorial craniotomy. The main questions it aims to answer are: Does ultrasound-guided scalp block reduce changes in heart rate and blood pressure during surgery compared with surgical site infiltration? Does ultrasound-guided scalp block decrease postoperative pain and opioid requirements in the first 24 hours after craniotomy? Researchers will compare patients receiving an ultrasound-guided scalp block to those receiving standard surgical site infiltration to see if the scalp block provides better perioperative hemodynamic control and postoperative analgesia. Participants will: Receive general anesthesia with either ultrasound-guided scalp block or surgical site infiltration Have heart rate, blood pressure, and other hemodynamic parameters monitored throughout surgery Receive standard postoperative pain management, with pain scores recorded at 0, 2, 6, 12, and 24 hours Receive opioids as needed based on pain scores, with total opioid consumption and time to first analgesic dose recorded Be monitored for adverse events, including nausea, vomiting, sedation, and block-related complications
