麻醉后留置导尿在妇科手术中的应用

目的针对麻醉前后导尿对患者的生理反应、不适程度及非肾小球性红细胞检出率进行对照研究，探讨留置导尿的最佳时机。方法将100例妇科手术患者随机分为两组，每组50例，实验组患者手术室麻醉后留置导尿，对照组患者进入手术室前半小时在病房导尿。比较两组患者导尿前、导尿时的脉搏、血压、不适程度，监测导尿后尿液中非肾小球性红细胞的阳性结果。结果对照组患者插管时的脉搏、血压高于插管前，差异有统计学意义（P〈0．05）；实验组患者插管前后脉搏、血压无变化（P〉0．05）；对照组和实验组患者导尿后尿液中非肾小球性红细胞阳性检出率第1次分别为30．0％，12．0％，第2次分别为24．0％，6．0％，差异均有统计学意义（x2值分别为4．882，6．353；P〈0．05）；对照组患者导尿时不适程度高于实验组患者，差异有统计学意义（P〈0．01）。结论为了减少术前导尿引起的不适和尿道黏膜损伤，导尿宜选择麻醉后。

Application of the catheterization after anesthesia in gynecologic operative

Objective To explore the best time of catheterization so as to reduce patients＇ physiological responses,discomfort,and the detection rate of non-glomerular red blood cells caused by catheterization before and after anesthesia, and explore. Methods Totals of 100 cases received gynecological surgery were randomly divided into experimental group （n = 50 ） and control group （n = 50 ）. In the experimental group catheterization was applied after anesthesia, while in the control group half an hour before entered the operating room in the ward. The pulse, blood pressure, and discomfort of two groups were recorded before and after catheterized, and the positive of non-glomerular red blood cells in urine after catheterization were monitored. Results There was significantly difference in the plus systolic, blood pressure before and after catheterization in control group （ P 〈 0.05 ） , while no significantly difference was detected in experimental group （P 〉 0.05 ）. The positive rate of non- glomerular red blood cells in control group and experimental group respectively was 30.0% and 12.0% in the first test,and the second was 24.0% and 6.0% ,the difference was statistically significant （X2 =4.882,6. 353, respectively ;P 〈 0.05 ）. The discomfort level in control group was significantly higher than that in experimental group （ P 〈 0.01 ）. Conclusions In order to reduce the discomfort and mucosal injury caused by catheterization, the best time to be select is after anesthesia.
