Ultrasound-guided scalp block to improve blood pressure, heart rate stability and pain after craniotomy

Official title: Efficacy of Scalp Block on Intraoperative Hemodynamic Responses and Postoperative Analgesia in Patients Undergoing Craniotomy

Run by Bangladesh Medical University · NCT07496632 · Data updated 2026-11-12

In adults having elective craniotomy, this study tests whether an ultrasound-guided scalp block reduces intraoperative heart-rate and blood-pressure changes and lowers pain and opioid needs in the first day after surgery.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-64 undergoing elective supratentorial craniotomy with ASA I-II and BM I range, BMI 18-30, GCS 9-15.

Probably not a fit

Patients who do not experience a notable reduction in intraoperative hemodynamic changes or postoperative pain may see no benefit from the scalp block.

What this trial studies

This randomized, interventional study compares an ultrasound-guided scalp block plus general anesthesia to standard surgical site infiltration with local anesthetic during elective supratentorial craniotomy. Primary questions are whether the scalp block smooths intraoperative hemodynamic fluctuations and decreases postoperative pain and opioid consumption within 24 hours. Participants receive general anesthesia and are assigned to receive either the scalp nerve block or the infiltration technique, with continuous monitoring of heart rate, blood pressure, and other vitals during surgery. Ultrasound guidance is used to improve accuracy and safety of the scalp block. The trial aims to determine if targeted regional anesthesia can improve perioperative stability and analgesia, potentially reducing systemic analgesic requirements.

Why it matters

Potential benefit: If successful, patients may experience more stable intraoperative vital signs and better pain control after surgery, with less need for opioids.

How similar studies have gone: Previous regional anesthesia approaches in cranial procedures have shown potential for improved analgesia and reduced opioid use, though results vary by technique and setting.
