logistic regression and chi using SPSS program (Windows, version 12.0). During the first 24 hours 87% of the patients experienced pain (NRS 1 to 3: 32%, NRS 4 to 7: 44%, NRS 8 to 10: 11%). For postoperative analgesia, the opioid piritramide (a mu-receptor agonist) was administered to 70% and nonopiod analgesics to 73% of the patients. The probability of experiencing postcraniotomy pain was reduced by 3% for each year of life. Maintenance of anesthesia with sevoflurane increased the probability of suffering from postcraniotomy pain by 147% and the absence of corticosteroids by 119%. Other investigated parameters did not influence pain after craniotomy. This study shows that pain is experienced by the majority of patients after craniotomy, despite conventional pain management, emphasizing the necessity for improved and individualized pain management in this special group of patients.

The overall incidence of PONV within 24 hours after craniotomy was approximately 50%. One possible reason is that intracranial surgeries pose an additional and independent risk factor for vomiting, especially in female patients. Patients undergoing craniotomy should be identified as high-risk patients for PONV.
