Scalp block versus general anesthesia for burr‑hole evacuation of subdural hematoma

Scalp Block Versus General Anesthesia in Patients Undergoing Evacuation of Subdural Hematoma Via Burr Hole

Not applicable Interventional Sohag University · NCT07143799

This trial tests whether using a scalp block instead of general anesthesia helps adults (18–75) having burr‑hole evacuation of a subdural hematoma.

What this trial studies

Adults with subdural hematoma who meet eligibility criteria will be assigned to receive either a scalp block (local anesthetic) or standard general anesthesia (including cisatracurium for muscle relaxation) for burr‑hole evacuation. The study will compare intraoperative stability, postoperative pain control, immediate complications, and early recovery measures between the two approaches. Key inclusion criteria include age 18–75, ASA II–III, and GCS ≥8, while patients with coagulopathy, local infection, significant heart block, or known drug sensitivity are excluded. The procedure and assessments are conducted at a single center (Sohag University Hospital).

Who should consider this trial

Good fit: Adults 18–75 with subdural hematoma scheduled for burr‑hole evacuation who are ASA II–III, have GCS ≥8, and do not have coagulopathy, infection at the injection site, heart block, or known sensitivity to study drugs are ideal candidates.

Not a fit: Patients with GCS <8, impaired coagulation, active infection at the injection site, significant heart block, or allergy to the study drugs are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, this approach could reduce anesthesia‑related risks and improve pain control and early recovery after burr‑hole evacuation.

How similar studies have performed: Scalp block has been used in cranial surgery to reduce pain and blunt hemodynamic responses, but evidence specifically for burr‑hole evacuation is limited.
