摘要
目的 探讨纠正和避免静脉补钾性疼痛的有效方法。方法 选择 16 0例补钾患者随机分为A、B、C、D 4组 ,每组 40例。A组实施常规穿刺法进行不同浓度、滴速、时间和剂量补钾的疼痛测定 ;B、C、D组分别应用常规穿刺法、抬高针尾法和翻转针柄法穿刺固定补钾测定疼痛 ,并另把B、C组疼痛患者作为E组 ,实施二次翻转针柄固定 ,测其缓痛情况。结果 含钾 0 15 %和 0 3%浓度的疼痛发生率分别为 75 0 %和 95 0 %(P <0 .0 1) ;滴速 30滴 /min和 6 0滴 /min疼痛发生率分别为 6 7 5 %和 95 0 %(P <0 .0 1) ;持续补钾 2h和 4h疼痛发生率分别为 85 0 %和97 5 %(P <0 .0 5 ) ;持续补钾 2 g/d和 4g/d疼痛发生率分别为 87 5 %和 97 5 %((P <0 .0 5 )。 3种穿刺固定方法的疼痛发生率分别为 95 0 %、90 0 %和 12 5 %(P <0 .0 1) ,具有显著差别 ;发生疼痛患者二次翻转针柄缓痛率为96 7%,且缓痛时间多为 (80± 42 )s。结论 钾离子是致痛因子 ,单位时间内流经血管的钾离子数目和疼痛的发生呈正相关。钾离子和血管组织的距离及药物流向与疼痛发生相关 ,翻转针柄法是纠正和避免静脉补钾疼痛的有效方法。
Objective In order to study the effective method of relieving the patients from pain caused by intravenous.Supplencent of potassium.Method 160 patients were randomized into four groups(A,B,C,D).There were 40 patients in each group.The routine puncture method was used in group A of different,time and drop velocity.Routine puncture medthod,elevating needles tail and reversing needle's handle were used in group B,C,D respectively.The pain was weasured in these four groups respectively.Result The incidence of pain was high when the was high,the time was long and the drop velocity was high.The incidence of pain was 95.0%,90.0% and 12.5%(P<0.01) respectively wity these three methods were used.Conclusion K + is the factor that cause the pain.And the close of K + is positive with the incidence of pain.The method of reversing the needle's handle is effective to relieve pain.
