To determine whether the use of a postural support nappy (PSN) would reduce the features of 'flattened posture' in the lower extremities of infants < 31 weeks gestation who are nursed prone.
Randomized, observer blind, controlled trial conducted at King Edward Memorial Hospital for Women, Perth, Western Australia. Infants were randomly assigned and stratified by gestational age to be nursed in a conventional nappy (n = 29) or a PSN (n = 31) when in the prone position. The features of 'flattened posture' were measured as angles and assessed by blinded observers prior to commencement of the intervention, 4 weeks post intervention, then bi-weekly until discharge.
A significant reduction in the features of 'flattened posture' occurred in the PSN group after 4-6 weeks of intervention and stabilized by 8 weeks until discharge. No changes were detected in the control group. No significant difference was observed between infants < 29 weeks gestation compared to infants of 29-30 weeks gestation in either treatment group.
Use of the PSN in infants < 31 weeks gestation who are nursed in the prone position significantly reduces the features of 'flattened posture' in the lower extremities. This is of benefit in the short term, and follow up of these infants into childhood will demonstrate whether the long-term effects of 'flattened posture' can be prevented.
确定使用体位支撑尿布（PSN）是否会减少妊娠小于31周且俯卧护理的婴儿下肢“扁平姿势”的特征。
在西澳大利亚珀斯的爱德华国王纪念医院妇女医院进行随机、观察者盲法、对照试验。婴儿按胎龄随机分组并分层，俯卧时使用传统尿布（n = 29）或PSN（n = 31）进行护理。“扁平姿势”的特征以角度测量，并在干预开始前、干预后4周，然后每两周一次直至出院时由盲法观察者进行评估。
干预4 - 6周后，PSN组“扁平姿势”特征显著减少，并在8周时稳定直至出院。对照组未检测到变化。在任何一个治疗组中，妊娠小于29周的婴儿与妊娠29 - 30周的婴儿之间均未观察到显著差异。
在妊娠小于31周且俯卧护理的婴儿中使用PSN可显著减少下肢“扁平姿势”的特征。这在短期内有益，对这些婴儿进行儿童期随访将证明是否可以预防“扁平姿势”的长期影响。
