【摘要】 <正> 为阐明普鲁卡因混合液维持全身麻醉(以下简称普鲁卡因静脉复合麻醉)对正铁血红蛋白形成的作用,我们于1983年4月至1984年4月对部分病例取血测血气及血氧饱和度,借以间接了解此种麻醉正铁血红蛋白产生情况。一、麻醉诱导后及术终两个阶段血气、血氧饱和度比较(表一):术终血氧饱和度更多还原

【Abstract】 Patients’ arterial blood gases and oxygen saturation were determined directly for confirming induced methemoglobinemia during procaine balanced intravenous anesthesia. The results demonstrated that this method could affirmatively diagnose marked methemoglobinemia only. In addition, we also presented 5 cases with marked cyanosis during procaine balanced intravenous anesthesia, in whom the arterial oxygen tension was all above 144mmHg, but oxygen saturation of arterial blood was all under 87％. One of the cases was curedby methylene blue administration.更多还原
