Controversies surround the practice of prescribing potassium for ambulatory hypertensive patients who are being treated with diuretics. A chart review was conducted in a family medicine group practice to examine habits of potassium monitoring and supplement prescribing for patients receiving diuretic therapy for control of hypertension. Eighty-four percent of the 134 patients studied were monitored for serum potassium. For those with values obtained both before and after institution of diuretic therapy, mean potassium fell from 4.1 mEq/liter to 3.8 mEq/liter and 29 percent of patients had potassium levels fall to 3.5 mEq/liter or less. Almost half of patients received some type of potassium therapy, with diet enrichment and pharmacologic supplementation being the most common. When mean serum potassium values and percentage of patients with hypokalemia were compared for patients who were prescribed potassium therapy and for those who were not, there was little evidence that patients benefited from potassium prescribing.
对于正在接受利尿剂治疗的门诊高血压患者，是否开具钾剂存在争议。在一个家庭医学团体诊所进行了一项图表回顾，以检查接受利尿剂治疗以控制高血压的患者的钾监测习惯和补充剂开具情况。在研究的134名患者中，84%的患者接受了血清钾监测。对于那些在开始利尿剂治疗前后均获得钾值的患者，平均钾水平从4.1毫当量/升降至3.8毫当量/升，29%的患者钾水平降至3.5毫当量/升或更低。几乎一半的患者接受了某种类型的钾治疗，其中饮食强化和药物补充最为常见。当比较接受钾治疗的患者和未接受钾治疗的患者的平均血清钾值和低钾血症患者百分比时，几乎没有证据表明患者从开具钾剂中受益。
