Abstract:
Objective To investigate the effect of patient-controlled intravenous analgesia (PCIA) with dexmedetomidine mixed with sufentanil on the sleep quality after spinal surgery.Methods Eighty patients of both sexes, aged 21-72 yr, weighing 48-100 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , scheduled for elective spinal surgery, were randomly assigned into sufentanil group (group S) and dexmedetomidine mixed with sufentanil group (group DS) with 40 cases in each group.In group S, PCIA solution contained sufentanil 2 μg/kg and tropisetron 6 mg in 100 ml of normal saline.In group DS, PCIA solution contained sufentanil 2 μg/kg, dexmedetomidine 3 μg/kg and tropisetron 6 mg in 100 ml of normal saline.The PCA pump was set up with a 0.5 ml bolus dose, a 15 min lockout interval and background infusion at a rate of 2 ml/h.Sufentanil 5 μg injected intravenously and celecoxib 200 mg given orally were used as rescue analgesics, and numeric rating scale (NRS) score at rest was maintained ≤4 within 48 h after surgery.Ramsay sedation scores were recorded at 1, 2, 6, 12, 24 and 48 h after surgery.Sleep quality was evaluated using the Medical Outcomes Study Sleep Scale (MOS-SS), and the average time of daily sleep and Sleep Problems Index (SPI) were recorded at week 1 before and after surgery.Patient's satisfaction with sleep was assessed on the night of surgery and 1st day after surgery.The requirement for rescue analgesics was recorded.Results There was no significant difference in the requirement for rescue analgesics between group S and group DS (P＞0.05).Compared with the value before surgery, the average time of daily sleep was significantly shortened, and SPI was increased at week 1 after surgery in group S (P＜0.05 or 0.01), and no significant change was found in group DS (P＞0.05).Compared with group S, the Ramsay sedation scores were significantly increased at 1, 2, and 6 h after surgery, the average time of daily sleep was prolonged at week 1 after surgery, the SPI was decreased at week 1 after surgery, and the degree of satisfaction with sleep was increased on 1st day after surgery in group DS (P＜0.05 or 0.01).Conclusion PCIA with dexmedetomidine mixed with sufentanil is helpful in improving the sleep quality after spinal surgery in the patients.
