Summary

Pain management in patients undergoing neurosurgery is a very important issue. The effectiveness of USG-guided scalp blocks for pain management in craniotomy surgery is currently not known. The purpose of this clinical trial is to evaluate the effectiveness of ultrasound-guided scalp block when performed in patients who undergo supratentorial craniotomies.

Detailed description

The main research questions this trial will answer are: 1. In patients undergoing elective supratentorial craniotomy under general anaesthesia, does USG-guided scalp block affect postoperative pain compared to standard treatment? 2. In patients undergoing elective supratentorial craniotomy under general anaesthesia, does USG-guided scalp block affect postoperative opioid consumption compared to standard treatment? 3. In patients undergoing elective supratentorial craniotomy under general anaesthesia, does USG-guided scalp block affect intraoperative haemodynamic parameters (blood pressure and heart rate) compared to standard treatment? This clinical trial compares ultrasound-guided scalp block with ropivacaine 0.375% versus standard treatment. The findings of this clinical trial may potentially revolutionise the practice of regional anaesthesia and analgesia in intracranial surgeries. This will lead to better patient outcomes by improving the perioperative care of patients undergoing craniotomy surgery.

Conditions

• Pain, Postoperative
• Anesthesia

Interventions

Type	Name	Description
PROCEDURE	Ultrasound-guided scalp block with ropivacaine 0.375%	Scalp block will be performed under USG guidance, using the technique described by Tsan et al. The block needle used will be an echogenic block needle, with a length of 50 mm, and a diameter of 22 G. Trained personnel comprising of the investigators in this study will perform the scalp block. Using ultrasound to identify landmarks, ropivacaine 0.375% will be administered in volumes of 1.5 ml to 3 ml. The nerves targeted will be the supraorbital, supratrochlear, zygomaticotemporal, auriculotemporal, greater auricular, lesser occipital, greater occipital and third occipital nerves.
