Efficacy of Liposomal Bupivacaine Scalp Nerve Block for Postoperative Pain Management After Supratentorial Craniotomy

Sponsor: Beijing Tiantan Hospital

Summary

This is a prospective, randomized, controlled trial conducted at Beijing Tiantan Hospital to evaluate the efficacy and safety of liposomal bupivacaine for scalp nerve block in managing postoperative pain after elective supratentorial craniotomy. A total of 118 eligible patients (aged 18-64, ASA I-III) will be randomly assigned in a 1:1 ratio to one of two groups. The intervention group will receive a scalp nerve block using liposomal bupivacaine. The control group will receive a scalp nerve block using standard 0.5% bupivacaine. All patients will undergo standardized general anesthesia. The primary outcome is postoperative pain intensity, measured by the Numerical Rating Scale (NRS) at multiple time points: 2, 12, 24, 48, and 72 hours after surgery. Secondary outcomes include the Glasgow Coma Scale (GCS) score, patient satisfaction, cumulative opioid consumption, and the incidence of adverse events. The study aims to determine if a single administration of liposomal bupivacaine provides superior and prolonged analgesia compared to conventional bupivacaine, potentially improving pain management and recovery for craniotomy patients. The study duration is from October 2024 to May 2027.
