Evaluation of effect of compound lidocaine cream in indwelling urethral catheter in cardiac operation / 重庆医学

ABSTRACT

Objective To evaluate the surface anesthesia and antibacterial effect of compound lidocaine cream in indwelling urethral catheter in order to seek the optimal indwelling urethral catheter scheme in cardiac surgery.Methods A total of 198 patients undergoing elective cardiac surgery in this hospital from November 2016 to January 2017 were selected and divided into the two groupsthe lidocaine cream group(L) and liquid paraffin control group(C).The visual analogue scale (VAS) and catheter-related bladder discomfort(CRBD) were used immediately after tracheal catheter extubation and at 2,4 h after extubation.The number of white blood cells and bacteria in urine were observed on postoperative 1,7 d.The urine culture results were observed on postoperative 7 d.Results The VAS and CRBD scores immediately after extubation in the group L was significantly lower than that in the group C(P＜0.05).The urine WBC count and bacterial count on postoperative 7 d in the group L were significantly lower than those in the group C(P＜0.05),the positive rate of urine culture on postoperative 7 d in the group L was significantly lower than that in the group C,the difference was statistically significant(5.05％ vs.13.13％,P＜0.05).Conclusion Compound lidocaine cream as lubrication indwelling urethral catheter can decrease the incidence rate of urinary tract infection on postoperative 7 d in the patients with cardiac operation,furthermore can prevent the wake agitation caused by indwelling urethral catheter.
