Evidence and rationale supporting return of bowel sounds as an unreliable indicator of the end of postoperative ileus after abdominal surgery are provided.
A loss of gastrointestinal motility, commonly known as postoperative ileus (POI), occurs after abdominal surgery. Since the 1900s, nurses and other clinicians have been taught to listen for return of bowel sounds to indicate the end of POI. Evidence-based nursing literature has challenged this long-standing traditional nursing practice.
The purpose of this study was to provide evidence from a randomized clinical trial and rationale supporting evidence-based inquiry concerning return of bowel sounds as an unreliable indicator of the end of POI after abdominal surgery.
Time (days) of return of bowel sounds after abdominal surgery was compared to the time (days) of first postoperative flatus, an indicator of the end of POI, in 66 patients recovering from abdominal surgery randomized to receive standard care compared to those who received standard care plus a rocking chair intervention.
Pearson's correlation between time to first flatus and return of bowel sounds for combined groups was not significant (r = 0.231, p = 0.062, p < 0.05) indicating that time to return of bowel sounds and time to first flatus were not associated.
The results of this study provide support to evidence-based inquiry that questions the relevance of traditional nursing practice activities such as listening to bowel sounds as an indicator of the end of POI.
提供了支持肠鸣音恢复作为腹部手术后术后肠梗阻结束的不可靠指标的证据和理论依据。
腹部手术后会出现胃肠动力丧失,通常称为术后肠梗阻(POI)。自20世纪以来,护士和其他临床医生一直被教导要听诊肠鸣音恢复情况以指示POI的结束。循证护理文献对这种长期存在的传统护理实践提出了挑战。
本研究的目的是提供一项随机临床试验的证据以及理论依据,以支持关于肠鸣音恢复作为腹部手术后POI结束的不可靠指标的循证探究。
将66例接受腹部手术的患者随机分为两组,一组接受标准护理,另一组接受标准护理加摇椅干预,比较腹部手术后肠鸣音恢复的时间(天)与术后首次排气的时间(天),术后首次排气是POI结束的一个指标。
合并组首次排气时间与肠鸣音恢复时间之间的Pearson相关性不显著(r = 0.231,p = 0.062,p < 0.05),表明肠鸣音恢复时间与首次排气时间无关。
本研究结果为循证探究提供了支持,该探究质疑了诸如听诊肠鸣音作为POI结束指标等传统护理实践活动的相关性。
