血压及血气分析对急性磷化铝中毒预后的影响

Effect of blood pressure and blood gas analysis on prognosis of patients with acute aluminum phosphide poisoning

目的观察急性磷化铝中毒患者的血压、血气分析对预后的影响.方法回顾性分析2012年2月-2016 年4月收治的24例口服磷化铝中毒患者的临床资料,按预后结局分成死亡组11例和存活组13例,分别统计住院时血压及血气分析数值,将两组结果进行对比.结果死亡组的血压、 pH、 HCO3^-值显著低于存活组,乳酸水平显著高于存活组,差异有统计学意义（P〈0.001）.结论严重的低血压状态和代谢性酸中毒预后极差,血压、血气分析对预后评价具有重要意义.

Objective To observe the effects of blood pressure and blood gas analysis on the prognosis of patients with a-cute aluminum phosphide poisoning. Methods Clinical data of 24 patients with acute aluminum phosphide poisoning admit-ted to hospital from February,2012 to April,2016 were analyzed retrospectively, and all patients were divided into death group（11 cases） and survival group（13 cases）.And then, blood pressure and numerical value of blood gas analysis during hospitalstay were calculated and compared between the two groups. Results Values of blood pressure, pH and HCO3^- in the deathgroup were obviously lower than those in the survival group, but lactic acid level was obviously higher than that in survivalgroup,so difference was statistically significant（ P 〈0.001）.Conclusion The prognosis of severe low blood pressure and met-abolic acidosis is very poor,and blood pressure and blood gas analysis are of great significance to the prognosis.
