Recent researches suggest that preterm infants understand pain and stress. Because of the wide range of effects of pain on infants, the present study was conducted on the effect of environmental and behavioral interventions on pain due to heel-prick blood sampling in preterm infants.
A clinical trial was conducted among 32 infants with gestational age of 32-37 weeks in the intervention and control groups. The effects of noise reduction by earplugs, light reduction by blindfolds, reduction of nursing manipulation, and creation of intrauterine position for neonates, 30 minutes before taking blood samples until 30 minutes after it, were measured during the intervention stage. Data were collected using the Neonatal Infant Pain Scale (NIPS) in 5 stages (before intervention, 2 minutes before sampling, during the sampling, and 5 minutes and 30 minutes after the sampling). The data were analyzed using analysis of variance (ANOVA) and paired -test in SPSS software.
The paired -test results showed no significant differences between the control and intervention stages in terms of pain scores at base time ( = 0.42) and 2 minutes before sampling ( = 0.12). However, at the sampling time ( = 0.0), and 5 minutes ( = 0.001) and 30 minutes after the sampling ( = 0.001), mean pain score in the intervention stage was significantly less than that in the control stage.
Based on the findings, environmental and behavioral interventions reduced pain and facilitated heel-prick blood sampling in preterm infants.
近期研究表明，早产儿能够感知疼痛和压力。鉴于疼痛对婴儿有广泛影响，本研究旨在探讨环境和行为干预对早产儿足跟采血所致疼痛的影响。
在干预组和对照组中，对32名孕周为32 - 37周的婴儿进行了一项临床试验。在采血前30分钟至采血后30分钟的干预阶段，测量了使用耳塞降噪、使用眼罩减少光线、减少护理操作以及为新生儿营造子宫内姿势等措施的效果。在5个阶段（干预前、采血前2分钟、采血期间、采血后5分钟和30分钟）使用新生儿疼痛量表（NIPS）收集数据。在SPSS软件中使用方差分析（ANOVA）和配对检验对数据进行分析。
配对检验结果显示，在基础时间（P = 0.42）和采血前2分钟（P = 0.12），对照组和干预组的疼痛评分无显著差异。然而，在采血时（P = 0.0）、采血后5分钟（P = 0.001）和30分钟（P = 0.001），干预组的平均疼痛评分显著低于对照组。
基于研究结果，环境和行为干预可减轻早产儿的疼痛，并有助于足跟采血。
