目的:分析白噪声干扰法对缓解早产儿穿刺疼痛的临床效果.方法:选取78例住院早产儿,按住院号尾号奇偶数分为实验组38例和对照组40例.实验组采用白噪声干扰法,对照组采用常规体位安抚法.使用早产儿疼痛评分简表(PIPP)和患儿啼哭发生率观察护理干预的临床效果.结果:实验组早产儿穿刺后心率最大值明显低于对照组(P<0.05),血氧饱和度最低值明显高于对照组(P<0.05),两组PIPP得分有统计学差异(P<0.05).对照组穿刺操作后啼哭发生率为80.0％,实验组为65.8％,差异具有统计学意义(P<0.05).结论:白噪声干扰法能明显缓解早产儿穿刺疼痛.“,”Objective: To analyze the effect of white noise interference method in relieving puncture pain of premature infants. Methods: Totally 78 premature infants were recruited in this study, 38 infants in experimental group and 40 infants in control group. White noise interference method was used in experimental group, and posture comfort method was implemented in control group. The Premature Infant Pain Proifle (PIPP) and cry incidence after puncture were used to evaluate the effect. Results: There were significant differences in heart rate, oxygen saturation and PIPP scores between experimental group and control group (P<0.05). The cry incidence was higher in control group than that in experimental group (80％ vs 65.8％,P<0.05). Conclusion: The white noise interference method could be useful in relieving puncture pain of premature infants.
