老年慢性心力衰竭患者低钠血症的相关因素分析及护理
Analysis of related factors and nursing methods for hyponatremia in the elderly patients with chronic heart failure
目的 探讨老年慢性心衰患者发生低钠血症的相关因素,为临床防治低钠血症及护理提供依据.方法 选择解放军总医院老年心内科住院的65岁以上慢性心力衰竭患者143例,其中低钠组47例,非低钠组96例;低钠组中年龄≥80岁高龄患者29例,年龄65 ~ 79岁老年患者19例;比较各组患者临床资料及特点.结果 低钠组年龄(88.5±4.8)岁,非低钠组年龄(82.5±7.5)岁,差异有统计学意义(t=4.895,P<0.01);低钠组患者高血压、肺部感染、糖尿病患病率、急性左心衰发生率及利尿剂、鼻饲使用率均高于非低钠组,两组比较,差异有统计学意义(x2值分别为26.034,14.492,5.385,10.881,12.674,5.389;P <0.05).高龄老年组补钠至正常值所需时间(11.7 ±3.0)d,老年组补纳至正常值所需时间为(7.6±2.1)d,差异有统计学意义(t=5.069,P <0.01).结论 老年慢性心衰患者发生低钠血症易诱发急性左心衰;高龄慢性心衰患者发生低钠血症时症状常不典型,容易被忽视,提示护理人员在护理时注意观察,及时监测血钠,以免延误病情.
更多Objective To study the related factors of hyponatremia in the elderly patients with chronic heart failure in order to provide evidences for preventing and nursing of hyponatremia.Methods Clinical data of 143 patients over 65 years old were investigated.The patients were divided into hyponatremia group (n =47)and control group (n =96).There were 29 cases with more than 80 years older and 19 cases with 65-79 years older in hyponatremia group.The data from the two groups were compared.Results The patients in hyponatremia group were significantly older than these in control group [(88.5 ± 4.8) vs (82.5 ± 7.5),t =4.895,P <0.01),and the incidences of hypertension,pneumonia,diabetes and acute heart failure,as well as the usage of diuretics and nasogastric tubes in hyponatremia group were significantly higher than that in the control group(x2 =26.034,14.492,5.385,10.881,12.674,5.389;P < 0.05).Very elderly patients needed longer time to achieve normal natrium level in blood serum than that elderly patients (t =5.069,P < 0.01).Conclusions Hyponatremia of the elderly patients with chronic heart failure was related to hypertension,pneumonia,diabetes,acute heart failure,usage of diuretics and nasogastric tubes.The symptoms of hyponatremia in very elderly patients is atypical,which are very likely to be neglected.We should pay more attention to the special population.
