78例剖宫产病人随机分为 3组 , 、 组各 30例 , 组 18例 ,硬膜外穿刺置管 , 组分次注入 1.5 %盐酸利多卡因 ,p H4.83; 组分次注入 1.73%碳酸利多卡因 ,p H7.3; 组为单硬 ,一次性注入 1.73%碳酸利多卡因 13ml～ 15 ml(3组药液均含 1∶ 2 0万 u肾上腺素 )。结果 :与 组比较 , 组麻醉起效时间 ,阻滞完善时间 ,有非常显著缩短 (P<0 .0 1) ;镇痛持续时间3组无明显差异 (P>0 .0 5 ) ;HR减慢 组显著 (P<0 .0 5 ) ,SPO2 、MAP3组无明显差异 (P>0 .0 5 )。说明碳酸利多卡因可安全地用于剖宫产 ,且效果优于盐酸利多卡因
78 cases of cesarean section were randomly divided into 3 groups, 30 cases in each group, 18 cases in group, epidural catheterization, sub-injection of 1.5% lidocaine hydrochloride, p H4.83; % Lidocaine carbonate, p H7.3; group of single-hard, one-time injection of 1.73% lidocaine carbonate 13ml ~ 15ml (3 groups of liquid contains 1: 20000u epinephrine). Results: Compared with the group, the time of onset of anesthesia and the time of complete block were significantly shortened (P <0.01); there was no significant difference in duration of analgesia between the three groups (P> 0.05) Slow group (P <0.05), SPO2, MAP3 group no significant difference (P> 0.05). Description of lidocaine carbonate can be safely used for cesarean section, and the effect is better than lidocaine hydrochloride
