Acute postoperative pain is a common postoperative adverse reaction. It refers to acute pain that occurs immediately after surgery and usually lasts no longer than 3-7. Among the craniotomy approaches, patients undergoing supratentorial craniotomy with temporal approach had a higher incidence of moderate to severe pain within 24 hours. In the management of postoperative acute pain, multimodal analgesia is recommended. Liposomal bupivacaine was encapsulated by liposomal vesicles and released slowly, lasting up to 72 hours. The long action time also makes the time window of postoperative acute pain completely covered, thus helping patients better control pain. At present, there is an obvious lack of clinical studies on the effectiveness and specific duration of liposome bupivacaine for postoperative acute pain, especially in neurosurgical craniotomy population with transtemporal incision approach, which is a high-risk group for postoperative pain in neurosurgery.

After standardized anesthesia induction, bilateral scalp nerve block (supprorbital nerve, auriculotemporal nerve, major occipital nerve, minor occipital nerve) was performed with liposome bupivacaine stock solution, and 1-2ml was injected into each block site.
After standardized anesthesia induction, bilateral scalp nerve block (supraorbital nerve, auriculotemporal nerve, major occipital nerve, minor occipital nerve) was administered with 0.5% ropivacaine, and 1-2ml was injected into each block site.
