Abstract:

Objective To investigate the effect of bedside ultrasound-guided chest physiotherapy combined with fiberoptic bronchoscopy suction on airway clearance in critically ill patients receiving mechanical ventilation. Methods A total of 100 critically ill patients receiving mechanical ventilation who were treated at Tianjin Union Medical Center from December 2023 to March 2025 were prospectively enrolled. Using a random number table, the patients were divided into an observation group (50 cases) and a control group (50 cases). The control group received conventional airway clearance measures, whereas the observation group received bedside ultrasound-guided chest physiotherapy combined with fiberoptic bronchoscopy suction. Oxygenation indicators, lung ultrasound scores, airway clearance efficacy, clinical outcomes, and adverse reactions were compared between the two groups. Results After treatment, oxygenation index increased and lung ultrasound scores decreased in both groups. The observation group had significantly higher oxygenation index values and significantly lower lung ultrasound scores than the control group (P<0.05). After treatment, the observation group had significantly greater airway secretion clearance and higher sputum expectoration effectiveness scores than the control group (P<0.05). The observation group had significantly shorter mechanical ventilation time and intensive care unit length of stay than the control group (P<0.05). The incidence of adverse reactions was lower in the observation group than in the control group (P<0.05). Conclusion A bedside ultrasound-guided combined airway clearance strategy can effectively improve oxygenation, promote lung recruitment, shorten the duration of mechanical ventilation in critically ill patients receiving mechanical ventilation, and is safe and worthy of clinical promotion.
