Objective:To investigate the effects of dezocine combined with sufentanil on continuous epidural analgesia after cesarean section.Methods:Eighty-six pregnant women who were scheduled for cesarean section in Guoyang Hospital of Traditional Chinese Medicine from February to December 2021 were included in this randomized controlled study. These women were divided into an observation group and a control group ( n = 43/group). The women in the observation group underwent epidural analgesia with dizocine, sufentanil, and ropivacaine, while those in the control group underwent epidural analgesia with dizocine and ropivacaine. The visual analogue score, Ramsay sedation score, Bruggrmann comfort scale score, and the incidence of adverse reactions were compared between the two groups. Results:At 4, 8, 12, 24 hours after surgery, the visual analogue score (VAS) in the observation group was significantly lower than that in the control group ( t = 2.34, 5.89, 15.36, 16.23, all P < 0.05). At 4, 8, 12, and 24 hours after surgery, Ramsay sedation score in the observation group was significantly higher than that in the control group ( t = -6.31, -7.64, -7.49, -7.41, all P < 0.001). At 4, 8, 12, and 24 hours after surgery, Bruggrmann comfort scale score in the observation group was significantly higher than that in the control group ( t = -7.60, -10.40, -14.53, -13.80, all P < 0.001). There was a significant difference in the number of effective analgesic pump compressions between the observation and control groups [(3.00 ± 1.41) times vs. (7.23 ± 1.31) times, t = 14.42, P < 0.001]. No adverse reactions were observed in the observation group within 24 hours after surgery. Conclusion:Dezocine combined with sufentanil for epidural analgesia can effectively improve the analgesic effects after cesarean section and is highly safe.

Objective To evaluate the effect of dexmedetomidine on postoperative outcomes in pa-tients undergoing off-pump coronary artery bypass grafting ( OPCABG) . Methods One hundred and twen-ty-two patients of both sexes, aged 40-75 yr, with body mass index of 18. 5-32. 0 kg∕m2 , of American So-ciety of Anesthesiologists physical status Ⅲ or Ⅳ, with New York Heart Association Ⅱ or Ⅲ, with lelf ventricular ejection fraction>40％, scheduled for elective OPCABG, were divided into 2 groups ( n=61 each) using a random number table method: dexmedetomidine group ( group D) and control group ( group C) . Dexmedetomidine was intravenously infused in a loading dose of 0. 6μg∕kg at 15 min before anesthesia induction, followed by a continuous infusion of 0. 4 μg · kg-1 · h-1 until the end of surgical procedure in group D. The equal volume of normal saline was given instead in group C. The emergence time, extubation time, length of intensive care unit stay and postoperative length of hospital stay were also recorded. Results Compared with group C, the extubation time, length of intensive care unit stay, and postoperative length of hospital stay were significantly shortened, and the emergence time was prolonged in group D ( P<0. 05) . Conclusion Dexmedetomidine can promote postoperative outcomes in the patients undergoing OPCABG.
