心电监护在低钾型周期性麻痹患者补钾中的意义

目的分析心电监护在低钾型周期性麻痹(HOPP)患者补钾中的意义。方法将我科收治的87例HOPP患者随机分为两组:试验组(50例)行心电监护,对照组(37例)行心肌监护,给予积极补钾治疗,每小时测定血钾和肌力一次。观察两组患者补钾后的血钾浓度及高钾T波例数。结果补钾1 h后,室性心律失常均消失。补钾2 h后,患者血钾水平普遍上升,补钾过程中未出现严重心律失常。心电监护T波正常时血钾水平低于肌力恢复达到4级时血钾水平(P<0.05)。结论心电监护在HOPP患者补钾的监护中高效安全,T波改变的识别是监护技术的关键。

Significance of ECG Monitoring in Potassium Supplementing of Patients with Hypokalemic Periodic Paralysis

Objective To investigate the clinical value for electrocardiogram(ECG)monitoring in potassium supplementing of patients with hypokalemic periodic paralysis(HOPP).Methods 87 patients of HOPP in our office were divided into two groups:experiment group(50 cases)and control group(37 cases).The experiment group accepted ECG while the control group accepted cardiac muscle monitor during potassium-supplement.ECG was needed when supplementing potassium.Hypokalemia and muscle strength were checked one time each hour.The serum potassium and cases of hyperkalemia T wave after potassium supplement were observed.Results After 1 h potassium supplementing,all ventricular arrhythmia disappeared.After 2 h,serum potassium levels generally increased,no severe arrhythmia appeared during the potassium supplementing process.Serum potassium level during normal ECG T wave was lower than that when the muscle strength recovered to grade 4(P<0.05).Conclusion ECG monitoring in potassium supplementing of HOPP patients is efficient and safe,and T-wave changes identification is the key to the monitoring technology.
