136例重危神经外科患者中的严重碱中毒

Severe alkalosis in 136 critically ill neurosurgical patients

从136例神经外科重危病人中获得544个血气测定与 pH 测定标本。各种硷中毒是最常见的酸硷平衡失调,在全部病人中有109例,占80.15%;而各种酸中毒仅10例,占7.35%;正常17例,占12.50%。死亡率与硷中毒程度之间存在着明显的关系。提示,无论硷中毒怎样产生或为何产生,尽快对他进行预防或纠正是非常重要的。

A retrospective study was undertaken to elucidatethe changes of acid-base in critically illneurosurgical patients.544 samples of arterialblood gas and pH determinations were obtained from136 neurosurgical patients.17 of 136 cases werenormal in acid-base balance,occurring in 12.5%.During hospitalization,alkalosis of all kinds wasthe most common acid-base disturbance as hasbeen observed in 109 of 136 patients(80.15%),while different acidosis occurred in 10 of 136patients(7.35%)and normal acid-base balancewas found in 17 patients(12.50%).A significantcorrelation was present between mortality and thedegree of alkalosis.Regardless of how or why thesevere alkalosis develops,it appears to beimportant to prevent or correct it as soon aspossible.
