罗哌卡因浸润麻醉联合地佐辛静脉麻醉对食管癌根治术患者全麻恢复期应激反应的影响

目的探讨罗哌卡因浸润麻醉联合地佐辛静脉麻醉对食管癌根治术患者全麻恢复期应激反应的影响。方法择期行食管癌根治术患者144例,男79例,女65例,年龄37~72岁,ASAⅡ或Ⅲ级,随机分为地佐辛组(D组,n=48),罗哌卡因组(R组,n=47)和罗哌卡因联合地佐辛组(RD组,n=49)。D组患者于切皮前10min用20ml生理盐水进行浸润麻醉(1∶200 000肾上腺素),R组和RD组患者于切皮前10min用20ml 0.5%罗哌卡因行浸润麻醉;R组患者于手术结束前30min静脉注射2ml生理盐水,D组和RD组患者于手术结束前30min静脉注射10mg地佐辛。记录三组患者术中出血量、手术时间、麻醉恢复时间、拔管时间、麻醉药物用量,分别于麻醉诱导前(T0)、术毕(T1)、拔管后即刻(T2)、拔管后10min(T3)、拔管后30min(T4)时,记录患者BP、HR,检测患者血丙二醛(MDA)、肾上腺素(E)和去甲肾上腺素(NE)的浓度,记录患者麻醉恢复期躁动及不良反应发生情况。结果 R组和RD组患者麻醉恢复时间和气管拔管时间明显短于D组,丙泊酚和舒芬太尼用量明显少于D组(P0.05);与T0时比较,T1~T4时三组患者SBP均明显升高,T3时D组和R组DBP明显升高、HR明显增快(P0.05);T3时RD组的DBP明显低于、HR明显慢于D组和R组(P0.05);与T0时比较,T1~T4时三组患者血糖、Cor、MDA、E和NE浓度均明显升高(P0.05);T1~T4时RD组的血糖、Cor、MDA、E和NE浓度均明显低于D组和R组(P0.05);三组患者麻醉期间均未出现头痛、头晕、呼吸抑制、咽喉疼痛等不良反应。RD组患者躁动和高血压发生率均明显低于D组和R组(P0.05)。结论罗哌卡因浸润麻醉联合地佐辛静脉麻醉应用于食管癌根治术可有效降低患者麻醉恢复期应激反应的发生,减少患者躁动的发生。

Effects of ropivacaine infiltration combined with dezocine intravenous on stress response during recovery from general anesthesia in patients undergoing esophageal cancer surgery

Objective To investigate the effects of ropivacaine infiltration combined with dezo-cine intravenous on stress response during recovery from general anesthesia in patients undergoing e-sophageal cancer surgery.Methods One hundred and forty-four patients of esophageal cancer under-going elective surgery were randomly divided into dezocine group (group D,n = 48 ),ropivacaine group (group R,n =47)and ropivacaine combined with dezocine group (group RD,n =49 ).Before slicing 10 min,patients in group D were taken 20 ml saline infiltration anesthesia (1∶200 000 epi-nephrine),while in group R and group RD were taken 20 ml 0.5% ropivacaine infiltration anesthesia. Patients in the group R were injected intravenously 2 ml saline,while in group D and group RD were injected intravenously 10 mg dezocine 30 min before the end of surgery.Peri-operative bleeding,oper-ation time,recovery time of anesthesia,extubation time and the dosage of propofol and sufentanil of three groups were recorded respectively.At the time points of before induction of anesthesia (T0 ), the end of the surgery (T1 ),removal trachea immediate (T2 ),10 min (T3 )and 30 min (T4 ),the blood pressures and heart rates were recorded,and the serum levels of malondialdehyde (MDA),epi-nephrine (E)and norepinephrine (NE)were detected.Results Recovery time of anesthesia and extu-bation time in group R and group RD were shorter than that in group D significantly (P <0.05).The dosage of propofol and sufentanil in group R and group RD were less than that in group D significantly (P <0.05).Compared with T0 ,SBP in three groups were elevated significantly at T1-T4 (P <0.05), DBP and HR in group D and group R increased significantly at T3 (P <0.05).DBP and HR in group RD at T3 were lower than that in group D and group R significantly (P <0.05).Compared with T0 , the levels of blood sugar,Cor,MDA,E and NE in three groups were elevated significantly at T1-T4 (P <0.05).The levels of blood sugar,Cor,MDA,E and NE in group RD at T1-T4 were lower than that in group D and group R significantly(P < 0.05 ).The incidences of agitation and elevation of blood pressure in group RD were lower than that in group D and group R significantly (P <0.05 ). Conclusion Ropivacaine infiltration combined with dezocine intravenous applied in the esophageal cancer surgery could effectively reduce the stress response during recovery from anesthesia,and de-crease the incidence of agitation.
