摘要
为探讨逆行胰胆管造影术（ERCP）中患者者氧发生原因及规律、吸氧的有效性及其适宜浓度，对290例ERCP受检者进行脉搏血氧饱和度（SPO2）监测术中，实验组患者检查前5min开始吸氧直至结束；对照组不吸氧。每5min记录一个血氧饱和度最低值。结果表明，两组患者在扬人十二指肠镜过程中SPO2皆明显下降，经术中给氧，实验组术中患者缺氧的发生率明显低于对照组（P＜0．05）；实验组氧流量2L／min时，16．5％的患者仍发生不同程度缺氧。作者认为（1）进镜过程是护主监测的一个重点；（2）镇静药作用下行ERCP检查，预防性吸氧可以降低ERCP检查中缺氧的发生率。
To explore the regularity of hypoxia, the effect of supplementary oxygen and the proper flow rate of oxygen, we studied saturation of pulse oxygen with a pulse oximeter in 290 patients undergoing endoscopic retrograde cholangiopancreatography. The patients were divided into two groups:the experimental group and the control group. The patients in the experimental group were given 2 liters of supplementary oxygen per minute,starting from 5min before the procedure to the end. The patients of the control group received no supplementary oxygen. The value of oxygen saturation was recorded every 5min. Saturation of pulse oxygen decreased remarkably in the process ofendoscope entering the upper digestive tract. The morbidity of hypoxia in the experimental group was significant lower than that in the control group, but there were still 16. 5 percent of the patients who suffered from hypoxia in the experimental group. So the period of inserting endoscope was very important for nursing. The morbidity of hypoxia during endoscopic retrograde cholangiopancreatography may be reduced by prophylactic supplementary oxygen. The appropriate amount of supplementary oxygen is 4 liters per minute during endoscopic retrograde cholangiopancreatography in patients who received conscious sedation.
