Clinical Trial Summary

Pain is common for the first 2 days after major craniotomy. A majority of patients would suffer from moderate-to-severe postoperative pain after undergoing craniotomy. Inadequate analgesia induced sympathetically mediated hypertension may lead to an increased risk for post-operative complications, such as arterial hypertension, intracranial hemorrhage, prolonged hospital stay, and mortality. Adequate pain control is essential for patients' prognosis and their postoperative life quality. Pain after craniotomy derives from the scalp and pericranial muscles. Local anesthetics administered around the incision have been performed clinically. However, some studies revealed that the analgesic effect of local anesthetics was not unsatisfactory due to its short pain relief duration. Pain is common for the first 2 days after major elective intracranial surgery, and the relatively short analgesic time of scalp infiltration does not seem to meet the requirements of craniotomy. Steroid such as diprospan as an adjuvant to local anesthetics intra-articular injected locally ameliorated pain intensity in knee osteoarthritis or in total knee arthroplasty. However, there has not been reported about local application of diprospan on scalp infiltration. Thus, the investigators suppose that pre-emptive scalp infiltration with steroid (diprospan) plus local anesthetic (ropivacaine) could relieve postoperative pain after craniotomy in adults.
