[目的]探讨无痛条件下(静脉麻醉下)超声微探头在上消化道疾病检查的安全性。[方法]对入我院内镜中心的200例上消化道病变患者,在静脉麻醉下行超声胃镜检查,对术中发生的血氧饱和度(SpO2)改变、心率下降、呛咳、呃逆等情况进行分析。[结果]在静脉麻醉情况下,食管、胃、十二指肠病变出现SpO2<90%的发生率分别为8/90,9/90,3/20;心率<60次/min的发生率分别为8/90,9/90,3/20;呛咳2例均发生在食管上段和胃底部,2例呃逆发生在胃底部。[结论]在正确的体位和祛泡剂、适当的麻醉深度和严密监护下,结合内镜操作技巧,静脉麻醉下的超声胃镜检查安全、舒适。
[Objective] To investigate the safety of ultrasound microprobe in the diagnosis of upper gastrointestinal diseases under painless conditions (intravenous anesthesia). [Methods] The 200 patients with upper gastrointestinal tract who entered the endoscopy center of our hospital underwent ultrasound gastroscopy under intravenous anesthesia. The change of oxygen saturation (SpO2), heart rate, cough, hiccup and so on Analyze. [Results] The incidence of SpO2 <90% in esophageal, gastric and duodenal lesions was 8 / 90,9 / 90,3 / 20 and the incidence of heart rate <60 beats / min 8/90,9 / 90,3 / 20; choking 2 cases occurred in the upper esophagus and stomach, 2 cases of hiccup occurred in the bottom of the stomach. [Conclusion] Under the correct posture and anti-foaming agent, appropriate depth of anesthesia and strict monitoring, combined with endoscopic operating skills, intravenous anesthesia under endoscopy ultrasonography safe and comfortable.
