不同时机留置导尿对全麻病人的影响分析

目的 探讨不同导尿时机对全麻病人的影响. 方法 将200例普外科择期手术的全麻病人,随机分为两组,每组100人.实验组是病人进入手术室麻醉后,进行留置导尿.对照组为患者进入手术前30 min,在病房进行留置导尿.比较两组全麻病人导尿前、导尿后的心率、血压、尿道的影响程度. 结果 对照组全麻病人进入手术室后的血压、脉搏明显高于插管前,差异有统计学意义（P＜0.05）,实验组全麻病人插管前后的血压、脉搏无变化（P＞0.05）.实验组的全麻病人,尿道舒适度的影响明显高于对照组的病人,严重不舒适的程度明显少于对照组（x2=12.58,P＜0.01）.结论 选择全麻后30 min导尿,对全麻病人血流动力学影响小,提高了全麻病人的尿道舒适度.

Analysis on the Influence of Different Time Points of Catheterization in Patients Undergoing General Anesthesia Catheter

Objective To explore the impact of different time points of urethral catheterization in patients undergoing general anesthesia. Methods Two hundred patients scheduled for selective operation and underwent general anesthesia in de- partment of general surgery were randomly divided into two groups （each n = 100）. The patients of study group underwent ure- thral catheterization after anesthesia in the operating room, while the patients of control group underwent urethral catheterization in the ward at 30 minutes before surgery~ Before and after catheterization, the impact of urethral catheterization on the heart rate, blcocl pressure and comfort degree of detaining urethral catheter was compared between the two groups. Results Among the patients under general anesthesia in control group, blood pressure and pulse rate were significantly higher than those of before in- tubation, and the difference was statistically significant （P 〈 0.05）. Among the patients under general anesthesia in study group, no alteration was found in blood pressure and pulse rate between before and after intubation （P 〉 0.05）. The comfort degree of detaining urethral catheter in patients under general anesthesia in study group was significantly better than that in patients under general anesthesia in control group, but severe uncomfortable degree was significantly less than that of control group （X2= 12.58, P 〈 0.01）. Conclusions Urethral catheterization performed at 30 minutes after general anesthesia is a better choice because that could relieve the comfortlessness of dwelling urinary catheter and has little influence on cardiovascular hemodynamies of the patients.
