Abstract: Background: Dexmedetomidine in combination with opioids has been used for postoperative analgesia. The purpose of this study was to investigate the impacts of dexmedetomidine supplemented intravenous analgesia on morphine consumption and subjective sleep quality in elderly patients after open abdominal surgery. Methods: This was a pilot randomized controlled trial. 58 elderly patients (age ≥ 60 years) who underwent open abdominal surgery were randomized to receive either dexmedetomidine supplemented morphine analgesia (0.5 mg/ml morphine plus 2 μg/ml dexmedetomidine in 100 ml normal saline, DEX group) or morphine analgesia (0.5 mg/ml morphine in 100 ml normal saline, CTRL group) for 72 hours after surgery. Patient-controlled analgesia pump was programmed to deliver a 2ml bolus with a lockout interval of 8 minutes and a background infusion at a rate of 1 ml/h. The primary endpoint was 72-hour morphine consumption. Secondary endpoints included pain intensity, subjective sleep quality, and 30-day complications and mortality after surgery. Results: The 72-hour morphine consumption was lower in the DEX group than in the CTRL group (median 39.0 mg [interquartile range 37.3, 41.0] in the DEX group vs. 49.0 mg [45.5, 50.0] in the CTRL group; median difference -9.0 mg [95% CI -10.0, -6.0], P
