The limited literature on closed-system suctioning suggests a need for further research in this area. Information is lacking about the frequency of use of the closed versus the open system of suctioning and about the current patterns of practice of closed-system suctioning among nurses.
To determine the frequency of use of closed- versus open-system suctioning by critical care nurses and to describe the endotracheal suctioning practices of nurses who use closed-system suctioning, in particular the current practice of hyperoxygenation and hyperinflation.
A survey developed by the investigators was mailed to a stratified proportional sample of 241 critical care nurses who are members of the American Association of Critical-Care Nurses in a tristate area in the mid-Atlantic region of the United States. The 19-item questionnaire included both open and forced-choice items. The response rate was 50%.
Closed-system suctioning is common in the critical care setting, and current nursing practices of closed-system suctioning vary. Use of hyperoxygenation is more common than use of hyperinflation with closed-system suctioning. Nurses had knowledge deficits about the proper performance of hyperoxygenation and hyperinflation.
Further research on closed-system suctioning is warranted, especially on the practices of hyperoxygenation and hyperinflation and the effect of these interventions on the prevention of suctioning-induced hypoxemia.
关于封闭式吸痰的文献有限,这表明该领域需要进一步研究。目前缺乏关于封闭式吸痰与开放式吸痰使用频率以及护士当前封闭式吸痰操作模式的信息。
确定重症监护护士使用封闭式吸痰与开放式吸痰的频率,并描述使用封闭式吸痰的护士的气管内吸痰操作,特别是当前的预充氧和肺复张操作。
研究人员编制的一份调查问卷被邮寄给美国中大西洋地区一个三州区域内241名美国重症护理护士协会成员的分层比例样本。这份包含19个条目的问卷既有开放式问题,也有多项选择题。回复率为50%。
封闭式吸痰在重症监护环境中很常见,当前封闭式吸痰的护理操作各不相同。在封闭式吸痰中,预充氧的使用比肺复张更常见。护士在预充氧和肺复张的正确操作方面存在知识欠缺。
有必要对封闭式吸痰进行进一步研究,特别是关于预充氧和肺复张操作以及这些干预措施对预防吸痰引起的低氧血症的影响。
