摘要
总结２６例新生儿休克病人的血气分析，电解质及阴离子间隙的变化后指出：新生儿休克轻度者多为单纯性代谢性酸中毒，中、重度休克常存在二重酸碱紊乱，多为代酸合并呼酸。休克程度愈重发生高ＡＧ酸中毒的比例愈大，提出高ＡＧ酸中毒病人应避免纠酸过量转为代谢性碱中毒成为更复杂的三重酸碱紊乱，顽固性酸中毒应注意纠正低氧血症、原发病治疗，热量供应减少乳酸血症及丙酮酸血症，注意肾功能，合并呼吸衰竭及时呼吸器治疗以提高新生儿休克的治愈率。
After summing up the variations of the blood gaw analyses, electrolyte and AG in 26 cases shock newborns, we leson that: pure metabolic acidosis almost happens in slight shock, while medium or serious shock often exists super-acid-base disorders, metabolic aci- dosis combining respiratory acidosis. Expecting substitute formula should be used when metabolic acidosis is main, combining respiratory acidosis. If Psa CO_2, goes beyond the maxi- mum of 2. 66 KP. (20 mmHg), and P_aO_2<5. 33kp_a when oxygen of 50% concentration is breathed, it is necessary that mechanical respiration treats shock when hypoxemia esists. The more serious the level of shock is the greater the proportion of high AG acidosis is. In high AG acidosis patients, it should be avoided that the acidosis is corrected excessively and changes into metabolic alkalosis, becoming more comples trinal-acid-base disorders.Hy- poxemai should be corrected, primary disease be treated, and reanal failure be attended in in- tractable acidosis. DCA has obvious curative effect in correcting acidosis, especially lactic acidosis, and it will ratise the cure rate of shock newborns.
