A review of the arterial acid-base status on admission to hospital of 62 adults with severe salicylate poisoning showed that arterial pH was normal or high in most patients, but low in 8. The mean plasma salicylate concentrations of the acidaemic and nonacidaemic patients were similar and the difference in arterial pH was associated with a marked fall in standard bicarbonate in the former group. No significant difference of Pco(2) between the two groups was found, and hence no simple relationship exists between hypocapnia and the development of acidaemia in salicylate poisoning. Acidaemia is shown to be associated with impaired consciousness and to carry a grave prognosis.
对62例重度水杨酸盐中毒成人入院时的动脉酸碱状态进行回顾性分析发现,大多数患者的动脉pH值正常或偏高,但有8例偏低。酸血症患者和非酸血症患者的平均血浆水杨酸盐浓度相似,动脉pH值的差异与前一组标准碳酸氢盐的显著下降有关。两组之间的Pco(2)无显著差异,因此在水杨酸盐中毒中,低碳酸血症与酸血症的发生之间不存在简单的关系。酸血症与意识障碍有关,预后严重。
