临床上伴有低血镁的顽固性低血钾并非少见,这种类型的低血钾用常规补钾的方法往往难以纠正,从而导致不良后果。本文报告3例诊治经验如下。 病例1:男性,23岁。原患有先天性尿崩症。此次因外伤性脾破裂,于1985年3月15日行脾切除术。术前血钾4.1mmol/L,术后因多尿未能得到控制,导致严重脱水伴深昏迷。虽然在术后4d内每日补钾6.0～12.0g,但血钾仍进行性下降到2.8mmol/L,心率40/min,心音弱,心律不齐。心电图示频发性P波缺失,QT延长,T波倒置,时
It is not uncommon for clinically low blood magnesium refractory hypokalemia that is often difficult to correct with this type of hypokalemia using conventional potassium supplementation, resulting in adverse consequences. This article reports 3 cases of diagnosis and treatment experience are as follows. Case 1: Male, 23 years old. The original suffering from congenital diabetes insipidus. The traumatic spleen rupture, in March 15, 1985 splenectomy. Preoperative serum potassium 4.1mmol / L, postoperative polyuria failed to be controlled, leading to severe dehydration with deep coma. Although in the postoperative 4d potassium daily 6.0 ~ 12.0g, but the progressive decline in serum potassium to 2.8mmol / L, heart rate 40 / min, weak heart sounds, arrhythmia. ECG showed frequent P wave loss, QT extended, T wave inversion, when
