Arterial blood gas tensions were measured before and during upper gastrointestinal endoscopy, with (group I) and without (group 2) sedation with intravenous diazepam. There was a highly significant fall in the PaO2, which occurred in both groups and was therefore not attributable to diazepam. Measurement of FEV, and FVC before endoscopy had no predictive value for those patients whose PaO2 fell the most.
在上消化道内镜检查前及检查期间,对两组患者测量动脉血气张力,第一组(I组)静脉注射地西泮进行镇静,第二组(2组)不进行镇静。两组患者的动脉血氧分压(PaO2)均出现极显著下降,因此这并非地西泮所致。在内镜检查前对第一秒用力呼气容积(FEV)和用力肺活量(FVC)进行测量,对于那些PaO2下降幅度最大的患者没有预测价值。
