Postoperative pain at rest and analgesic use in patients receiving intrathecal morphine or placebo. a Average NRS pain scores were obtained during the first 4 h after TKA surgery. Bars represent the median and all data points are shown. Intrathecal morphine reduced acute postoperative pain (p = 0.0049). b Postoperative opioid use (morphine equivalent dose) measured via patient controlled analgesia during the first 12 h after surgery. Bars represent the median and all data points are shown. Intrathecal morphine reduced postoperative opioid use (p = 0.001)
