ABSTRACT
Objective To observe the influence of dezocine used before end of operation on postoperative recovery and its inter-vention effect on postoperative pain in the patients with gynecological laparoscopic operation .Methods 60 patients(ASA Ⅰ - Ⅱ ) scheduled hysterectomy operation by gynecological laparoscopy were randomly divided into the observation group (dezocine group , n=30) and the control group(normal saline group ,n=30) .Remifentanil combined with propofol was intravenously given for con-ducting endotracheal intubation general anesthesia .The observation group was given dezocine 0 .1mg/kg(diluting to 10mL by nor-mal saline) at 30-40 min before the end of operation ,while the control group was given the same volume of physiological saline . Blood pressure ,heart rate(HR) ,recovery time ,adverse reactions during the recover period and postoperative pain before induction , after injection and before recovery were recorded .Results The elevation of mean arterial pressure(MAP) and the increase of HR during the recovery period in the observation group were lower than those in the control group (P0 .05) .PO2 ,PCO2 and SaO2 had no statistical difference between the two groups (P>0 .05);the postoperative agitation-sedation scores(PASS) and the visual ana-logue scale(VAS) scores in the observation group were significantly lower than those in the control group (P<0 .05) ,and the oc-currence rate of chills also was lower than that in the control group (P<0 .05) .Conclusion Intravenous dezocine before the end of operation in the gynecological laparoscopic operation can effectively inhibit the cardiovascular stress reaction ,does not affect the re-covery speed ,moreover can decrease the restlessness during the recovery period and postoperative pain .
