水果补钾预防PCI围手术期低钾血症的效果观察

Effect of fruit potassium supplement on preventing hypokalemia at peri-PCI

目的探讨水果补钾预防经皮冠状动脉支架植入术(percutanous coronary intervention,PCI)围手术期低钾血症的效果。方法选择2011年7～12月本院收治的90例低钾血症拟行PCI的冠心病患者,在常规口服药物补钾治疗基础上,给予吃橙子和香蕉,每天各吃500g,分早、中、晚3次进食,持续至术前。观察患者入院时及手术当天、术后第1d、第3d血钾情况。结果患者术前口服水果补钾时间为12～45h,平均(28.84±11.70)h;患者手术当天及术后第1d、第3d血钾水平比入院当天明显升高(均P<0.05),而且维持在正常水平。结论进食香蕉和橙子可帮助患者快速纠正低钾血症,有效预防PCI围手术期低钾血症。

Objective To investigate the effects of fruit potassium supplement on hypokalemia at in the perioperative period of percutanous coronary intervention（PCI）.Methods Ninety cronary herat disease patients with hypokalemia undergoing PCI during July to December 2011 involved the study.Since admission,the patients were administered with oranges and bananas each 500 g daily until the third day after PCI,on the basis of oral administration of potassium.Serum potassium was assessed in all patients at time points of the day at PCI,the first day and third day after PCI.Results The time range for the patients to take potassium supplement by eating fruits was 12-45 hours,averaged（28.84 ± 11.70） hours.The serum potassium levels on days 1 and 3 were significantly higher than that on the day for the admission（P 0.05 for both） and even maintained at the normal level.Conclusion The oral complement of potassium by eating bananas and oranges can help patients to correct and prevent hypokalemia during the perioperative period of PCI.
