The most common method for preventing ventilator-associated pneumonia is maintaining airway clearance for efficient gas exchange, achieved by removing secretion through endotracheal or tracheal suctioning. Clearing the airway can be effectively achieved through various techniques, including thoracic squeezing. Thus, this study aimed to determine the effectiveness of thoracic squeezing on airway clearance, and respiratory parameters among mechanically ventilated patients.
A true experimental study was conducted with 60 mechanically ventilated patients who met the inclusion criteria in the ICUs and were randomly assigned to the study group ( = 30) and the control group ( = 30). Pre-intervention assessments of airway secretion, oxygen saturation, respiratory rate, and heart rate were measured before suctioning for both groups. Thoracic squeezing was administered to the study group 5 minutes before suctioning, while the control group received the hospital's routine care practices. Post-intervention assessments 1 and 2 were measured immediately and 15 minutes after suctioning, and the same process continued for three days in both groups.
The mean scores of airway secretion, respiratory rate, oxygen saturation, and heart rate from the pre- and post-intervention assessments 1 and 2 were compared using repeated measures ANOVA. The results revealed a high level of statistical significance ( < 0.001) for airway secretion and oxygen saturation and statistical significance ( < 0.05) for respiratory rate. However, no significant changes were observed in heart rate. An unpaired -test revealed that participants in the study group were significantly ( < 0.001) more effective in airway secretion and oxygen saturation than in the control group participants.
The current study's findings concluded that thoracic squeezing before endotracheal and tracheal suctioning enhances secretion removal, oxygen saturation, and respiratory rate without significant changes in heart rate among mechanically ventilated patients. Its notable influence could provide policymakers with valuable insights to make well-informed decisions, focused on improving healthcare systems and outcomes, especially within intensive care units.
预防呼吸机相关性肺炎最常用的方法是保持气道通畅以实现有效的气体交换,这可通过经气管内或气管吸引清除分泌物来实现。通过包括胸部挤压在内的各种技术可以有效地清除气道。因此,本研究旨在确定胸部挤压对机械通气患者气道清除和呼吸参数的有效性。
对重症监护病房中符合纳入标准的60例机械通气患者进行了一项真实实验研究,将其随机分为研究组(n = 30)和对照组(n = 30)。两组在吸痰前均对气道分泌物、血氧饱和度、呼吸频率和心率进行干预前评估。研究组在吸痰前5分钟进行胸部挤压,而对照组接受医院的常规护理措施。干预后评估1和评估2分别在吸痰后立即和15分钟进行测量,两组均持续三天进行相同的过程。
使用重复测量方差分析比较干预前评估1和评估2以及干预后评估1和评估2的气道分泌物、呼吸频率、血氧饱和度和心率的平均得分。结果显示,气道分泌物和血氧饱和度具有高度统计学意义(P < 0.001),呼吸频率具有统计学意义(P < 0.05)。然而,心率未观察到显著变化。非配对t检验显示,研究组参与者在气道分泌物和血氧饱和度方面比对照组参与者显著更有效(P < 0.001)。
本研究结果得出结论,在经气管内和气管吸痰前进行胸部挤压可增强分泌物清除、血氧饱和度和呼吸频率,而机械通气患者的心率无显著变化。其显著影响可为政策制定者提供有价值的见解,以便做出明智的决策,重点是改善医疗保健系统和结果,特别是在重症监护病房内。
