Abstract:
Objective:To evaluate the efficacy of S-ketamine mixed with hydromorphone for improving patient-controlled intravenous analgesia (PCIA) after lumbar spinal surgery.Methods:Ninety-six American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, aged 18-64 yr, with body mass index of 18.5-29.9 kg/m 2, scheduled for elective lumbar fusion surgery under general anesthesia, were divided into 2 groups ( n=48 each) using a random number table method: hydromorphone for PCIA group (group H) and S-ketamine mixed with hydromorphone for PCIA group (group S+ H). PCIA was performed at the end of operation.PCIA solution contained hydromorphone 0.05 mg/ml mixed with S-ketamine 0.25 mg/ml in group S+ H and hydromorphone 0.05 mg/ml in group H. The PCIA pump was set up to deliver a 2 ml bolus dose with a 10-min lockout interval, background infusion at 2 ml/h and total volume of 200 ml.When the numerical rating scale score ≥4 and analgesia was ineffective by pressing the PCA pump for 3 consecutive times, hydromorphone 0.2 mg was intravenously injected as rescue analgesic.The cumulative consumption of hydromorphone (consumption for analgesic pump and consumption for rescue analgesia) and occurrence of adverse reactions such as pruritus, respiratory depression, nausea, vomiting, drowsiness, dizziness, headache, hallucinations and nightmares within 48 h after operation were recorded.The patients′ satisfaction with analgesia was recorded at 48 h after operation.The time to first flatus after operation and quality of recovery (QoR-15 scale) at 24 and 48 h after operation were recorded. Results:Compared with group H, the cumulative consumption of hydromorphone within 48 h after surgery were significantly reduced, the patients′ satisfaction with analgesia was increased, the time to first flatus after operation was shortened, QoR-15 scores were increased at 24 and 48 h after operation ( P<0.05), and no significant change was found in the requirement for rescue analgesia and incidence of adverse reactions within 48 h after surgery in group S+ H ( P>0.05). Conclusions:Compared with PCIA with hydromorphone, S-ketamine mixed with hydromorphone can reduce postoperative consumption of hydromorphone, increase satisfaction with analgesia, and promote early postoperative recovery after lumbar spinal surgery.
