急性心肌梗死行介入治疗术后低血钾原因分析及护理

Main factors of hypokelemia after PCI for acute myocardial infarction

目的探讨急性心急梗死冠脉介入术后患者低钾血症发生原因,并总结护理要点。方法观察分析96例急性心肌梗死行冠脉介入患者术后发生低血钾情况及原因。结果 57例发生低钾血症,发生率为59.4%(57/96),给予饮食补钾、口服补钾、雾化吸入补钾及静脉补钾后,患者血钾恢复正常。低钾血症发生与术后摄入不足、排出过多、分布异常及造影剂的使用有关。结论急性心肌梗死介入治疗后患者较易发生低钾血症,术后应密切观察患者病情变化情况,针对原因采取多种补钾方式纠正患者低钾血症。

Objective To explore the main factors of hypokalemia in the patients with acute myocardial infarction after PCI.Method The clinical data of ninety-six patients with myocardial infarction after PCI were analyzed to look into the reasons for hypokalemia.Results Fifty-seven patients contracted hypokalemia,with a rate of 59.4%.The complication was cured by dietetic supplementation of potassium,oral supplementation of potassium,and potassium supplementation by atomization inhalation and intravenous infusion.The reasons for hypokelemia included inadequate input,over-ejectment,abnormal distribution of potassium and use of contrast agent.Conclusions Patients with myocardial infarction after PCI are more susceptible to hypokalemia.Therefore,it is a need to correct hypokelemia by means of potassium supplementation.
