This study was performed to assess the severity and duration of hypoxia during and after prolonged upper gastrointestinal endoscopy. Twenty patients were studied using a non-invasive pulse oximeter. Significant reductions in oxygen saturation were noted during endoscopy and remained below the preexamination level during the one hour period after the examination. This study indicates that pulse oximetry is a useful monitor for detection of hypoxia during and after endoscopy.
本研究旨在评估长时间上消化道内镜检查期间及检查后的缺氧严重程度和持续时间。使用无创脉搏血氧仪对20名患者进行了研究。在内镜检查期间发现氧饱和度显著降低,并且在检查后的一小时内仍低于检查前水平。本研究表明,脉搏血氧测定法是检测内镜检查期间及检查后缺氧情况的有用监测手段。
