Summary

This study aims to evaluate the effect of scalp block timing-whether administered preoperatively or postoperatively-on postoperative recovery quality in patients undergoing craniotomy. The recovery quality will be assessed using the validated Quality of Recovery-40 (QoR-40) questionnaire. A total of 60 patients, aged 18-80 years, classified as ASA I-III and with a Glasgow Coma Scale (GCS) score of 15 upon admission to the recovery unit, will be enrolled. The primary outcome is the QoR-40 score. Secondary outcomes include hemodynamic changes and pain intensity measured by the Visual Analog Scale (VAS).

Conditions

  • Scalp Block
  • Regional Anesthesia
  • Craniotomy Surgery
  • QoR-40

Interventions

PROCEDURE

Early Scalp Block Group

Following induction of general anesthesia and prior to head pinning (Mayfield clamp placement), a scalp block was performed under aseptic conditions using 20 mL of 0.25% bupivacaine. The block targeted six sensory nerves that innervate the scalp: Supraorbital nerve, Supratrochlear nerve, Auriculotemporal nerve ,Zygomaticotemporal nerve, Greater occipital nerve, Lesser occipital nerve. Each nerve was infiltrated subcutaneously at its anatomical location using a 25-gauge needle, with the total volume distributed evenly or proportionally across the injection sites.

PROCEDURE

Late Scalp Block Group

In the pre-emergence group, the scalp block was performed at the end of surgery but before emergence from general anesthesia, while the patient was still under deep anesthesia. Under strict aseptic conditions, 20 mL of 0.25% bupivacaine was administered to block the following six sensory nerves innervating the scalp: Supraorbital nerve, Supratrochlear nerve, Auriculotemporal nerve, Zygomaticotemporal nerve, Greater occipital nerve, Lesser occipital nerve. The local anesthetic was injected subcutaneously at the anatomical landmarks of each nerve using a 25-gauge needle. The total volume was distributed evenly or proportionally depending on the area. No additional surgical stimulation occurred after the block, and extubation followed routine emergence from anesthesia.
