The purpose of this research was to examine the effects of containment (restraint of an infant's movements) on premature infants' postsuctioning transcutaneous PO2 values. The hypothesis was that premature infants receiving containment would have significantly different postsuctioning transcutaneous PO2 levels than infants receiving no containment. Premature infants with respiratory disease require suctioning to remove excess secretions from their lungs. Research studies document a variety of infant responses to suctioning; hypoxia, hypoxemia, increased blood pressure, bradycardia, increased intracranial pressure, and increased cerebral blood flow velocity. Most studies have examined only a few isolated variables and the magnitude and duration of hypoxemia in response to suctioning. Our sample comprised 24 infants less than 72 hours of age, who had respiratory distress syndrome and had been born at between 24 and 33 weeks' gestational age. The setting was a neonatal intensive care unit of a large county hospital. The same nurse performed the suctioning and containment procedures in all subjects. Student's t-tests and analysis of variance were carried out to determine the effect of the technique.
本研究的目的是检验约束（限制婴儿活动）对早产儿吸痰后经皮氧分压值的影响。假设是接受约束的早产儿吸痰后的经皮氧分压水平与未接受约束的婴儿有显著差异。患有呼吸系统疾病的早产儿需要吸痰以清除肺部过多的分泌物。研究记录了婴儿对吸痰的多种反应；包括缺氧、低氧血症、血压升高、心动过缓、颅内压升高和脑血流速度增加。大多数研究仅考察了少数几个孤立变量以及吸痰后低氧血症的程度和持续时间。我们的样本包括24名年龄小于72小时、患有呼吸窘迫综合征且胎龄在24至33周之间的婴儿。研究地点是一家大型县医院的新生儿重症监护病房。同一名护士对所有受试者进行吸痰和约束操作。采用学生t检验和方差分析来确定该技术的效果。
