Clinical Report: Effects of Closed-System Suctioning on Self-Reported Breathlessness

Overview

This study investigates the impact of closed-system suctioning on dyspnea in mechanically ventilated patients. Results indicate a transient worsening of dyspnea immediately after suctioning, despite improved oxygen saturation levels.

Background

Dyspnea is a prevalent symptom in mechanically ventilated patients, often exacerbated by procedures like endotracheal suctioning. Understanding the acute effects of suctioning on patients' respiratory experiences is crucial for improving care in intensive care settings. This study aims to quantify these effects and their relationship with physiological parameters.

Data Highlights

Time PointD-VAS Score (Mean ± SD)
T0 (Before Suctioning)2.8 ± 1.9
T1 (Immediately After Suctioning)6.4 ± 2.1
T2 (5 min Post-Suctioning)3.2 ± 1.7

Key Findings

  • D-VAS scores increased significantly from 2.8 at T0 to 6.4 at T1 (P < 0.001).
  • 92.5% of suctioning procedures resulted in worsened dyspnea at T1.
  • 15.1% of patients had not returned to baseline dyspnea levels at T2.
  • SpO2 increased from 97.2% to 99.1% at T1, despite worsened dyspnea.

Clinical Implications

The study highlights the need for individual dyspnea assessments during routine suctioning in mechanically ventilated patients.

Conclusion

Closed-system suctioning may lead to transient increases in dyspnea, independent of oxygenation status.
