目的：探讨不同干预方式对早产儿足跟采血的疼痛缓解程度的区别。方法：选择2013年7月至2013年12月入住我院的早产儿156名进行完全随机分组，分为观察组A、观察组B、观察组C、对照组，观察组分别进行非营养性吸吮、营养补充性吸吮、抚触干预，对照组无安慰措施，根据早产儿对足跟采血穿刺过程中以及穿刺结束5 min后的疼痛评分(依据早产儿疼痛评分简表评测)和面部表情评分法进行评价，对比各组新生儿的评分情况进行分析。结果：观察组3个小组患儿在足跟采血的穿刺过程中，PIPP量表评分均低于6分，不需要镇痛治疗；在穿刺结束5 min后，其量表评分均有所降低，比对照组明显减轻；3个观察组患儿的疼痛表情均明显低于对照组评分；且观察组B的患儿评分几乎等于0，其面部表情评分最低，疼痛指数更佳，效果更好(P<0.05)。结论：通过对早产儿足跟采血进行不同的干预方法，对于疼痛均具有缓解作用，应用营养性吸吮效果更佳，临床中可以根据患儿具体情况，选择更合适的干预措施。
The comparative study of premature heel blood intervention to relieve pain
Objective: To investigate the effects of different interventions on premature heel blood pain relief. Methods: Selected 156 premature infants in our hospital from July 2013 to December 2013, randomly divided into observation group A, observation group B, observation group C and control group. The observation group A, B, C was respectively treated with non-nutritive sucking, nutritional supplement, sucking touch intervention; the control group was taken no relief measures. Evaluated the puncture pain score of premature infants on the process of the heel prick and 5 min after that (based on premature infant pain scores short table evaluation), and the facial expression score, compared the scores in each group. Results: During the heel prick on the children in the three observation groups, PIPP scores were all lower than 6, which showed no need for analgesic treatment; 5 min after the puncture, the scores all decreased and the difference was significant when compared with the control group. The pain expression scores in the three observation groups were significantly lower than those in the control group; the scores in group B is nearly 0, which has the lowest expression score, also has better pain index and effects (P<0.05). Conclusion: Different methods of intervention on premature heel lancing can alleviate the pain, and nutritive sucking has better effects. We should choose more appropriate intervention measures according to the specific situation of the children in the clinic.
