sensory block

Group C produced longest duration of sensory block among the four groups, and the time of motor recovery was not different with group B, but shorter than group A.

四组中，C组感觉阻滞持续时间最长，与其他组比较差异有显著性（P0.05），运动阻滞时间与B组比较没有差异（P0.05），明显比A组短（P0.05）。

The onset and duration of sensory and motor block, the block height, degree of abdominal muscle relaxation, anesthetic efficacy and side effects were recorded.

观察感觉阻滞起效时间、感觉阻滞达到的最高平面和时间、感觉阻滞持续时间、运动阻滞起效时间、运动阻滞持续时间、腹部肌肉松弛程度、麻醉效果、清醒程度及不良反应。

Both the duration of sensory and motor block and the level of motor block were positively related to the dose of ropivacaine.

感觉和运动阻滞持续时间以及运动阻滞深度与剂量呈正相关。

Results There were no significant differences between three groups in reacting time, maintaining time and the highest block level of sensory block after subarachnoid block ( P> 0.05).

结果：3组病人的感觉阻滞起效时间、维持时间、最高阻滞平面差异无显著性（P>0.05）；

Sensory and motor block, incidence of hypotension, blood gases of umbilical venous blood, Apgar score and NACS score of the neonates were investigated.

观察感觉和运动阻滞情况、血压的变化、新生儿脐静脉血气和Apgar、NACS评分。

These anaesthetics block sodium channels and thereby the excitability of all neurons, not just sensory neurons.

这些局麻剂可以阻断钠通道, 因此不仅仅阻滞了感觉神经元,也同时阻滞了几乎所有其他神经元的兴奋性.
