Abstract
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.

Description of the data and file structure
We compared the efficacy of 0.1 mg of intrathecal morphine to peripheral nerve blocks in pain control after various types of foot ankle surgeries by using propensity score analysis. Side effects of low dose intrathecal morphine were also recorded.

Human subjects data
Identifying numbers are eliminated including medical record numbers. Demographic data included only age and gender.
We include patients who received SB and peripheral nerve blockade (SBPNB) and patients who received SB with 0.1 mg of ITMO (SBMO). The primary endpoint was the proportion of patients who required rescue analgesics during the first 24 hours. Secondary outcomes were mean pain scores at the 6th, 12th, and 24th hours after surgery, side effects from ITMO and peripheral nerve blocks. Propensity score matching was performed, and the standardized mean difference (SMD) was used to measure the magnitude of differences in clinical characteristics, prognostic factors, and potential confounders. Cox’s proportional hazard regression was used to compare the proportion of patients who required rescue analgesic medication. Mean difference regression was used to compare pain scores at 6th,12th, and 24th hours.
