急诊洗胃后电解质紊乱的临床研究

Clinical study on electrolyte disturbance induced by emergency gastric lavage

目的探讨急诊清水洗胃后电解质及血浆渗透压的变化。方法 回顾性分析我院2012年10月~2014年9月急诊洗胃的患者273例,按年龄分为两组：A组（≥60岁）和B组（〈60岁）,洗胃前后进行抽血化验,对血钠、血钾、血浆渗透压结果进行比较,并进行BNP比较。结果 两组洗胃后血钾、血钠、血浆渗透压明显降低,与洗胃前比较,差异有统计学意义（P〈0.05）;≥60岁患者治疗前后BNP比较差异有统计学意义（P〈0.05）。结论急诊清水洗胃可导致电解质紊乱,少数患者出现严重并发症。

Objective To study the influence of emergency gastric lavage with pure water on the electrolyte and plasma osmotic pressure. Methods A total of 273 cases of patients in our hospital from October 2012 to September 2014 were sleeted, the serum sodium, serum potassium and the plasma osmotic pressure were measured and compared by using haemospasia before and after emergency gastric lavage with pure water. These patients were divided into two groups ac- cording to the age： Group A（≥60 years old） and Group B（〈60 years old ）, and the plasma brain natriuretic peptide （BNP） was determined and compared before and after therapy. Results After emergency gastric lavage with pure water, the serum sodium, the serum potassium and the plasma osmotic pressure of the patients were significantly reduced com- pared to the patients without treatment（P〈0.05）. In the group A, the BNP of the patients before and after therapy showed significant differences（P〈0.05）. Conclusion Emergency gastric lavage with pure water induces electrolyte dis- turbance, and even leads to severe complications in a few patients.
