【摘要】 目的探讨不同时间使用硫酸镁湿热敷防治含钾药物所致静脉疼痛的临床效果。方法采用自身对照,将第一天静脉输注含钾药物后引起静脉疼痛的患者作为对照组,在该患者再次输注相同含钾药物的同时,局部使用硫酸镁湿热敷,按随饥顺序,在将输注相同药物的第2、3、4、5d热敷15min、30min、60min、120min作为实验组,并在不同时间段分别观察热敷疗效。结果对照组与实验组各时间段疼痛评估均有显著性差异(P<0.05),热敷15min组与其它三组有显著性差异。而热敷30min、60min、120min三组之间无显著性差异。结论同步湿热敷各组在不同时间段止痛效果优于疼痛后再做湿热敷组;同步热敷硫酸镁30min与60min组、120min组相比,疼痛评估降至微疼以下。且硫酸镁湿热敷时间短,更容易被患者接受。更多还原

【Abstract】 Objective To investigate the effect of MgSO4 hot wet dressing at different time to prevent the pain caused by intravenous injection of medicine that contains K+. Method Patients with pain after intravenous injection of K+ solution were treated with MgSO4 hot wet dressing following the days before giving intravenous injection of K+ solution. They were randomly divided into 4 groups, e. g. the 2nd day, 3rd day , 4th day and 5thday, and were treated with MgSO4 hot wet dressing for 15 min, 30min, 60 min, and 120 min respectively. The effect of different time were observed and analyzed. Result The pain were all released after treatment (P<0. 05), The degree of pain released in 30min, 60 min, and 120 min groups is significantly higher than that of 15 min group. But there is no significant difference in pain release among 30min, 60 min, and 120 min groups. Conclusion The effect of pain releasing is better when hot wet dressing is given before the injection of K+ solution. Thirty minutes treatment is more preferable for the patients.更多还原
