本文分析了１１２例创伤后多器官功能衰竭酸碱失衡与预后的关系。结果表明，单纯性酸碱失衡４９例，死亡２４例，占４８．９％；混合型酸碱失衡６３例，死亡４５例，占７１．４％，两者有显著性差异（ｐ＜０．０５）混合型酸碱紊乱中以三重酸碱失衡和呼吸性酸中毒并代谢性酸中毒病死率最高。血气参数中，ｐＨ是影响预后的重要因素，ｐＨ＜７．３０者病死率为８３．３％，而ｐＨ＞７．３０者为５３．７％。ＰａＣＯ２和ＨＣＯ３－值对预后的影响较小。
This article analyzes 112 cases of multiple organ failure after acid-base imbalance and prognosis. The results showed that there were 49 simple acid-base imbalances and 24 deaths, accounting for 48.9%. There were 63 mixed acid-base imbalances and 45 deaths (71.4%), both of which were significantly different (p <0. 05) mixed acid-base disorders in triple acid-base imbalance and respiratory acidosis and metabolic acidosis highest mortality. Blood gas parameters, pH is an important factor affecting the prognosis, the mortality of patients with pH <7.30 was 83.3%, while those with pH> 7.30 were 53.7%. PaCO2 and HCO3-value on the prognosis less.
