About this trial
Supratentorial craniotomy is one of the most common neurosurgical procedures, with severe perioperative pain. Inadequate perioperative pain relief has been associated with increased blood pressure and intracranial pressure, favoring bleeding and cerebral cerebral hypoperfusion. The ideal analgesia for neurosurgery requires complete pain relief, eliminates the side effects of opioid drugs and no influence for neurological function. Previous studies have proposed a multimodal analgesic strategy, combining analgesics and local anaesthesia, it is expected to achieve the above benefits.
