在多种情况下,都可能发生不可逆的低氧性脑损伤,这对于行将进行全身麻醉的任何病人,是一种潜在的危险,今将有关的病理学和可能的治疗处理摘述如下: 吸呼当血流通过大脑时,血的含氧量由19.6ml/dl降至12.9ml/dl,二氧化碳则由动脉血的48.2ml/dl增加到颈内静脉中的54.8ml/dl。对大脑来说,其呼吸商近乎1.0,亦即是说,葡萄糖很可能是大脑的第一能量来源。正常成人在平稳状态下大脑的氧代谢率为3.2～3.8mlO_2/min/100克。 Salford、Plum、Seisjo等学者在近来
In many cases, irreversible hypoxic brain injury can occur, which is a potentially dangerous condition for any patient undergoing general anesthesia. A summary of the relevant pathologies and possible treatments is summarized below: Suction As blood flowed through the brain, blood oxygen levels decreased from 19.6 ml / dl to 12.9 ml / dl and carbon dioxide increased from 48.2 ml / dl of arterial blood to 54.8 ml / dl in the jugular vein. For the brain, its breathing quotient is almost 1.0, which means that glucose is probably the first energy source in the brain. Normal adults in the steady state of brain oxygen metabolism rate of 3.2 ~ 3.8mlO_2 / min / 100 grams. Salford, Plum, Seisjo and other scholars in the recent
