导尿时机选择对血流动力学的影响

The Effect on Timing Catherization for Haemodynamics

为选择全麻病人导尿最佳时机，减少导尿的不良刺激所导致血流动力学改变。本文选择６０例病人分三组，Ⅰ组全麻诱导用药后５ｍｉｎ，Ⅱ组全麻诱导用药后１０ｍｉｎ，Ⅲ组全麻诱导用药同时经尿道注入２％利多卡因３ｍｌ、石蜡油２ｍｌ，５ｍｉｎ后导尿，观察心率、血压的改变，其结果Ⅰ～Ⅲ组插尿管后心率、血压与入手术室后基础值比较，Ⅰ组Ｐ＜００５，Ⅱ组血压不仅不上升，而且下降Ｐ＜００５，Ⅲ组则平稳。本文认为导尿最佳时机应在麻醉后１０ｍｉｎ，若加强局部麻醉和尿道润滑作用效果会更佳。

To chose the best time of catherization for patients with general anesthesia, reduce the changes of haemody namics by side stimulation of catherization, we selected 60 cases divided into three groups: Ⅰ group was purposed doping of general a nesthesia in five minutes,Ⅱ group was in ten minutes,Ⅲ group was when Purposed doping of general anesthesia injected 2% gravocain 3ml and liquid paraffin 2ml by urethral Canal, then catheterized in five minutes. Heart ratel and blood pressure were observed. The result showed:after intubation the heart rate and blood pressure compared with the basic value when went into operation room, Ⅰ group was P <0 05,Ⅱ group's blood pressure were not raised but decreased( P <0 05),Ⅲ group were stablized. So the artical suggested the best time of catheterization be in ten minutes after anesthesia and if reinforced local narcosis and lubrication at urethral canal, the effect will be much better.
