Abstract
Objective: Comparing the clinical efficacy and safety of 0. 33% ropivacaine and 1% lido-caine epidural anesthesia for breast surgery. Method: Selected the 40 cases of ASA I ~ II elective breast cancer surgery randomly divided into two groups, all the patients were given T3-4 space catheterization. Group I was injected 0. 33% ropivacaine, the other group was injected 1% lidocaine. Comparison the two groups before anesthesia block, block after 10,20,30min while HR,SBP,DBP,SpO2 and VC, FVC, FEV1, MVV changes in the parameters. The onset time of anesthesis, the range and anesthesis block were also compared. Result; ①When blocked the two groups after 10, 20,30 min, HR was significantly slower than block (P<0. 05) , but SBP,DBP and SpO2 between groups was not statistically significant (P>0. 05). ②The two sets of indicators have decreased pulmonary function , however, the indicators of groups II decreased significantly compared with group I ,the difference was significant ( P<0.05) . ③The two groups of patients in the anesthesia onset time, block scope and effect of anesthesia was no significant difference (P>0.05). Conclusion: 0.33% ropivacaine hydrochloride epidural anesthesia in radical mastectomy is better than 1% lidocaine towards the pulmonary function.关键词
