Data from: Efficacy and safety of intrathecal morphine compared to peripheral nerve blocks in patients underwent foot and ankle surgery: A propensity score analysis

Intrathecal morphine (ITMO) is one of the most effective analgesic techniques in various types of surgery. Spinal anesthesia (SB) is commonly used in lower extremity surgery; thus, adding 0.1 mg of morphine is easy. Ultrasound-guided peripheral nerve block requires skill and equipment, and the rebound pain is also of concern. This study aims to compare the efficacy of 0.1 mg ITMO and peripheral nerve blocks in postoperative pain control by using propensity score analysis to look back at real practice decisions.
