To determine the feasibility and effect size of kangaroo care (KC) for pain from heel lance in preterm neonates provided by either the infant's mother (MKC) or an unrelated alternate female (AFKC).
Using a randomized crossover design, preterm neonates (n = 18) between 28 and 37 weeks gestational age within 10 days of life from two university-affiliated level III NICU's undergoing routine heel lance were assigned to receive KC 30 min before and during the procedure from either their mother (MKC) or an unrelated woman. In the second heel lance procedure at least 24 h later but within 10 days, the infants were crossed over to the other condition.
There was a 48% participation rate, with only 40 of 82 eligible cases having maternal consent. The main reason for refusal was discomfort with another woman providing kangaroo care. The effect sizes on the pain scores (PIPP) were small, ranging from .23 to .43 across the first 2 min of procedure.
The difference between nonrelated females and the mother in decreasing pain response is small, although not negligible. Given the high refusal rate, nonrelated females are a less desirable alternative to mothers than fathers.
确定由婴儿的母亲（MKC）或无亲属关系的女性（AFKC）进行袋鼠式护理（KC）对早产儿足跟采血疼痛的可行性和效果大小。
使用随机交叉设计，在两个大学附属三级 NICU 中，出生后 10 天内胎龄为 28 至 37 周的早产儿在接受常规足跟采血前 30 分钟内被分配接受 KC，由其母亲（MKC）或无亲属关系的女性（AFKC）进行。至少在 24 小时后但在 10 天内的第二次足跟采血过程中，婴儿交叉到另一种条件。
参与率为 48%，仅有 82 名符合条件的病例中有 40 名获得了母亲的同意。拒绝的主要原因是不喜欢另一个女性提供袋鼠式护理。疼痛评分（PIPP）的效果大小较小，在手术的前 2 分钟内范围从.23 到.43。
尽管不明显，但与母亲相比，非亲属女性在减轻疼痛反应方面的差异很小。考虑到高拒绝率，非亲属女性不如父亲更适合作为母亲的替代者。
