ABSTRACT

Objective To investigate the optimum dose of dezocine combined with ropivacaine for elderly patient -controlled epidural analgesia(PCEA)after transurethal resection of prostate (TURP)surgery.Methods Totally 90 elderly patients underwent TURP surgery with ASAⅡ-Ⅲ were randomly divided into three groups,30 cases in each group.For postoperative epidural analgesia,they were treated with different mixed liquor as followinggroup Ffentanyl 0.3mg +1.192% ropivacaine 20mL +normal saline to 100mL,group D1dezocine 5mg +1.192% ropiva-caine 20mL +normal saline to 100mL,group D2dezocine 7.5mg +1.192% ropivacaine 20mL +normal saline to 100mL.VAS and Bruggrmann Comfort Scale(BCS)and sedation score at 4,8,12,24,36,48h and side -effects,sleep quality score and general satisfaction score at 24,48h after operation were recorded.The ratio of best analgesia was evaluated.Results VAS of 4,8,12,24,36,48h after operation had no significant differences among three groups (F =1.65,1.72,1.75,1.73,1.58,1.63,all P >0.05).BCS of all points had no significant differences among three groups(F =1.48,1.51,1.44,1.38,1.38,1.38,all P >0.05).Sedation score of all time points had no significant differences among three groups(F =1.55,1.60,1.61,1.00,1.00,1.00,all P >0.05).Sleep quality score of 24,48h after operation had no significant differences among three groups(F =1.76,1.84,all P >0.05).General satisfaction score of 24,48h after operation had no significant differences among three groups(F =1.73,1.72,all P >0.05).The excellent and good rates of analgesia in three groups were 90.0%,93.3% and 93.3% respectively,and there were no significant difference (χ2 =0.873,0.873,all P >0.05).Compared with group F and group D1,the incidence rates of nausea and vomit were significantly increased in group D2(χ2 =4.25,4.32,all P <0.05),and the incidence rates of dizziness were significantly increased in group D2 (χ2 =4.36,4.08,all P <0.05 ),and the incidence rates of drowsiness was significantly increased in group D2(χ2 =7.85,7.85,all P <0.05).There were no pruritus and respir-atory depression in three groups.Conclusion The optimum dose of dezocine combined with ropivacaine for elderly PCEA after TURP surgery is 5mg.It can provide adequate pain relief and higher satisfaction with less side -effects.
