Effect Observation of Different Dosages of Ropivacaine Dezocine Combined with Preemptive Analgesia in Laparoscopic Hysterectomy Postoperative Analgesia

Objective To compare the effects of different dosages of ropivacaine dezocine combined with preemptive analgesia in laparoscopic hysterectomy postoperative analgesia.Methods 90 patients were d randomly divided into Group A,Group B1 and Group B2 with 30 patients in each group.30 minutes before laparoscopic gynecologic operation with the hysterectomy stump suture,Group A received intravenous injection of dezocine 0.2mg/kg;Group B1 dezocine dosage 0.1mg/kg;Group B2 dezocine dosage 0.1mg/kg;while the two groups of B1 and B2 were sprayed with 0.5% ropivacaine around the cut before skin incision for blocking and 15ml of 0.25% ropivacaine before pulling the sleeve after pelvic operation;and the VAS scores after 0.5,2,6,12,24 hours were recorded in quiet and cough state,the recovery of postoperative spontaneous breathing extubation time,number of cases of the restlessness,restlessness of the situation of narcotic analgesics used,postoperative analgesia and adverse reaction of nausea and vomiting cases were recorded.Results Observed in a quiet state,compound medication on incision and abdominal pain of the two groups were good,the score of VAS4,no statistical significant difference(P0.05);postoperative nausea,vomiting occurrence rate of two groups were not statistically significantly different(P0.05).Postoperative extubation time was not statistically significant.Postoperative agitation incidence rate of three groups were not statistically significant.Group A and Group B pain after 2-6 hours of surgery had significant difference(P0.05).Conclusion Application of dezocine 0.1mg/kg joint Ropivacaine preemptive analgesia in gynecologic laparoscopic hysterectomy is safe and effective with few side effects;the application of small dose has small effect on postoperative recovery and can reduce postoperative agitation.
