微量泵静脉注射补钾3种缓解疼痛方法的比较

目的 比较3种方法 缓解微量泵静脉补钾疼痛的效果.方法 选择120例需静脉补钾的患者,随机分为3组,药物热敷组30 例,采用20 g/L 利多卡因热敷静脉穿刺上方部位;输液稀释组35例,采用留置针同一静脉连接液体和微量泵补钾;常规护理组33例,仅采取常规护理措施.比较3组疼痛程度及有无静脉炎发生和静脉炎级别.结果 3组患者微量泵静脉补钾时疼痛程度差异有统计学意义,输液稀释组与药物热敷组比较(Z=3.338,P<0.001),输液稀释组与常规护理组比较(Z=6.554,P<0.001),药物热敷组与常规护理组(Z=3.974,P<0.001),差异均有统计学意义,输液稀释组疼痛程度最轻,其次是药物热敷组.3组患者微量泵静脉补钾时静脉炎发生情况比较差异有统计学意义,输液稀释组与药物热敷组比较(Z=4.966,P<0.001),输液稀释组与常规护理组比较(Z=6.410,P<0.001),差异均有统计学意义,输液稀释组静脉炎发生率最低.结论 输液稀释法和药物热敷法都能有效缓解疼痛,输液稀释法疼痛程度和静脉炎发生率低于药物热敷法,且方法 简便,安全可行,避免再次穿刺血管的痛苦,患者易于接受,减少护士的工作量.

Comparison of 3 Pain-relief Ways of Potassium Supplementation with Micro Pump

Objective To compare the effects of 3 pain-relief ways of potassium supplementation through intravenous infusion with micro pump.Methods 120 patients were randomly divided into 3 groups,including hot-compress-with-medicine group(n=30) with 20g/L lidocaine in venous puncture point through hot compress,dilution-through-injection group(n=35),and conventional-nursing group(n=33).Pain degree,incidence and degree of phlebitis in three groups were compared.Results There were statistical significances of the compar...
