Abstract:
Objective To observe the clinical effect of dexamethasone combined with dezocine on the ultrasound guided interscalene brachial plexus block.Methods Accordance with the random number table,80 patients with ASAⅠ ~Ⅱ undergoing upper extremity operations were divided into four groups,with 20 cases in each group:group A was treated with 0.45% ropivacaine mesylate 20mL;group B was treated with 0.45% ropivacaine mesylate combined with dexamethasone 0.1mg/kg 20mL;group C was treated with 0.45% ropivacaine mesylate combined with dezocine 0.1mg/kg 20mL;group D was treated with 0.45% ropivacaine mesylate combined with dexamethasone 0.1mg/kg and dezocine 0.1mg/kg 20mL.The onset time,maximum block time,analgesia duration and the incidence of adverse reactions were recorded in the four groups.Results The onset time of group C and group D were faster than group A and group B[group C(3.65 ±0.88)min vs.group A(5.60 ±0.88)min,group B(5.35 ±0.81)min,t =7.303, 6.367,all P =0.000;group D(3.30 ±0.80)min vs.group A,group B,t =8.614,7.678,all P =0.000],the maximum block time of group C and group D were faster than those of group A and group B[group C(8.45 ±1.19)min vs. group A(12.75 ±2.05)min,group B(12.65 ±1.90)min,t =8.583,8.383,all P =0.000;group D(7.80 ±0.89)min vs.group A,group B,t =9.880,9.680,all P =0.000].The analgesia duration of the other groups were longer than those of group A[group B(430.50 ±30.86)min,group C(435.00 ±38.46)min,group D(534.50 ±46.73)min vs. group A(314.50 ±33.32)min,t =9.696,10.072,18.388,all P =0.000],group D was the best(group D vs.group B,group C,t =8.693,8.317,all P =0.000),there were no significant differences between group B and group C (group C vs.group B,t =0.376,P =0.708).In the 80 patients,only one case of group C had postoperative nausea and vomiting symptoms,there were no significant differences between the groups(all P >0.05).Conclusion Dexa-methasone combined with dezocine on the ultrasound guided interscalene brachial plexus block is a method with faster onset time,shorter maximum block time,longer analgesia duration,and it has less adverse reactions and better anesthetic effect,and it is more suitable for upper extremity operations.
