Preemptive injection of local anesthetics can prevent postoperative pain at the incision site, but the analgesic effect is insufficient and is maintained only for a relatively short period of time. Diprospan is a combination of quick-acting betamethasone sodium phosphate and long-acting betamethasone dipropionate. Whether Diprospan as an adjuvant to local anesthetic can achieve postcraniotomy pain relief has not been studied yet.
