冠心病心绞痛介入治疗术后血钾浓度改变分析

Analysis of the postoperative change of serum potassium in the angina pectoris patients by interventional therapy

目的观察冠心病心绞痛患者介入治疗后患者血清钾离子浓度变化情况并初步分析其原因。方法选择接受冠心病心绞痛支架介入治疗患者106例,介入治疗前1d查静脉血钾浓度,术后3h复查血钾浓度,对比手术前后血钾浓度变化。结果 106例接受介入治疗患者,术后29例发生低钾血症,发生率为27.4%。术前血钾3.50～3.99mmol/L者78例,术后26例发生低钾血症;术前血钾≥4.0mmol/L者28例,术后3例发生低钾血症。手术前后血钾浓度变化差异有统计学意义(P<0.05)。结论冠心病心绞痛患者介入治疗后低钾血症发生率较高,术前应将血钾浓度控制于较高水平,术后应监测血钾浓度并酌情补钾。

Objective To observe the change of serum potassium concentration after pereutaneous coronary intervention in patients with angina pectoris and to analyze the reason. Methods To select 106 patients suffering by angina pectoris,who receive treatment by PCI,and to detect their venous serum potassium concentration respectively in one day before PCI and in 3 hours after PCI,and to compare the differences. Results 29 patients suffering by hypokalemia after the operation in 106 patients and the incidence rate was 27.4% （29/106）. 26 patients suffering by hypokalemia after the operation in 78 patients with serum potassium concentration from 3.5 mmol/L to 3.9 mmol/L. 3 patients suffered by hypokalemia after the operation in 28 patients with serum potassium concentration between higher than or equal to 4.0 mmol/L. The serum potassium concentration differences between preoperation and afteroperation were statistically significant. Conclusion Angina pectoris patients after PCI have a higher incidence of posloperative hypokalemia,and concentration of serum potassium should be controlled at higher levels preoperation, and patients should be monitored for potassium detection after the operation and he Supplied with potassium aDnropriatelv.
