Arterial blood gases were analysed before and approximately one hour after premedication in two groups of 10 patients awaiting cardiac surgery. One group received intramuscular papaveretum and hyoscine, the other papaveretum and glycopyrronium. Similar, small but statistically significant reductions in mean arterial oxygen tension and oxygen saturation, and increases of arterial carbon dioxide tension occurred in both groups. Hypoxaemia in individual patients was unpredictable and in some was clinically relevant.
对两组等待心脏手术的10例患者，在术前用药前及用药后约1小时进行动脉血气分析。一组接受肌肉注射罂粟碱和东莨菪碱，另一组接受罂粟碱和格隆溴铵。两组患者的平均动脉血氧分压和血氧饱和度均出现类似的、轻微但具有统计学意义的降低，动脉血二氧化碳分压升高。个体患者的低氧血症无法预测，部分患者的低氧血症具有临床相关性。
