超声胃镜检查前口服链霉蛋白酶对检查清晰度的影响及护理

Effects of oral pronase before ultrasound gastroscopy on visibility and nursing

目的：探讨超声胃镜检查前口服链霉蛋白酶对检查清晰度的影响及总结护理要点。方法选择行超声胃镜检查的患者200例，按预约就诊顺序随机分为观察组和对照组，每组各100例。对照组患者内镜检查前15～30 min给予常规口服二甲硅油散，观察组患者在检查前15～30 min给予口服链霉蛋白酶及二甲硅油散。比较两组患者超声胃镜检查时胃镜下视野清晰度、胃镜操作时间及患者恶心呕吐情况。结果两组患者超声胃镜检查时视野清晰度、患者恶心呕吐程度、超声胃镜检查时间比较，均P＜0．01，差异具有统计学意义，观察组患者超声胃镜检查时视野清晰度明显优于对照组，恶心呕吐程度明显轻于对照组，超声胃镜检查时间明显短于对照组。结论超声胃镜检查前应用链霉蛋白霉可以去除胃黏液和泡沫，提高超声内镜的视野清晰度，缩短检查时间和提高患者舒适度。

Objective To explore the effects of oral pronase before ultrasound gastroscopy on visibility and summarize the key points of nursing. Methods Two hundred patients who received ultrasound gastroscopy were divided into observation group （n=100） and control group （n = 100） by random digit table. The patients in the control group routinely took dimethicone powder before endoscopy, while the patients in the observation group first took pronase 15 to 30 minutes before endoscopy and then dimethicone powder. The comparisons were done between the groups in terms of visibility, examination time, nausea and vomiting and adverse effects. Result Compared with the control group, the observation group showed significantly clearer visibility, shorter examination time, slighter nausea and vomiting and lower degree of intolerance （P〈0.01）. Conclusions Oral pronase before ultrasound gastroscopy examination can remove the mucus and bubbles in the stomach and improve visibility. It is good for shortening the examination and improving the patients′comfort level.
