🗡Severe pain ( > 4 on a 0–10 scale) is commonly experienced during the first 48h with an incidence of nearly 70% on the first postoperative day and 48% on the second postoperative day
🗡 Women, younger patients and patients who required opioid analgesics preoperatively report significantly greater levels of postoperative pain
🗡 Infratentorial procedures are associated with more severe pain than supratentorial procedures
🗡Reduced pain has been reported with a translabyrinthine as opposed to a suboccipital approach for acoustic neuroma resection
🗡The amount of muscle damage from resection of the temporalis and posterior cervical muscles may also influence the degree of postoperative pain
🗡Preoperative Gabapentin, parecoxib and lornoxicam may reduce opiate-induced hyperalgesia
🗡the addition of ondansetron to PCA has not been shown to reduce nausea and vomiting after craniotomy
🗡evidence suggests that NSAIDs should be stopped prior to neurosurgery and avoided in patients with cardiovascular disease.
🗡 Gabapentin given 7 days prior to surgery results in significantly lower postoperative pain scores and morphine consumption during the first 48 postoperative hours compared to phenytoin
🗡 Preoperative use of nerve blocks or local anesthetic infiltration reduces intraoperative analgesic requirements and may help to reduce pain in the early postoperative period
