Abstract
Background
In the case of critically sick patients, acute respiratory distress syndrome (ARDS) may be life-threatening and necessitates the need for ICU admission. Continuous monitoring is required for mechanical ventilation and recruitment movements as necessary. In this research, the goal is to investigate the use of ultrasonography in the evaluation of positive end exhalatory pressure-induced lung recruitment in ARDS patients.
Patients and methods
A total of 25 ARDS patients were included in this research, which was done in the hospital’s respiratory care unit. All of the patients were seen by a doctor, had a chest radiograph, and had laboratory tests. Mechanical ventilation was used in the care of all patients. Using positive end-expiratory pressure (PEEP) values of 5 and 15, we measured pressure–volume (PV) and lung ultrasound tracings. The PV curve approach was used to assess PEEP-induced lung recruitment. Between PEEP 5 and PEEP 15, there was an extremely strong positive connection between reaeration score and the change in lung volume (r=0.737, P=0.001).
Results
Between PEEP 5 and PEEP 15, there was a substantial (r=0.577, P=0.003) positive association between the reaeration score and the decrease in PaO2. There was a substantial negative association between reaeration score and mortality (rpb=-0.842, P=0.001), in which mortality reduces as the score increases.
Conclusion
For quantitative evaluation of PEEP-induced lung recruitment, bedside lung ultrasound is equal to the PV curve approach. In patients with ARDS, PEEP-induced lung recruitment may be assessed using ultrasonography. |
