| Sumario: | Background: Unloading the diaphragm by mechanical ventilation results in diaphragmatic dysfunction and atrophy, a condition recognized in critical care settings as ventilator-induced diaphragmatic dysfunction (VIDD). This condition contributes to prolonged mechanical ventilation, extubation failure and higher risk of mortality.The aim of The Study: The current study aimed to investigate the effectiveness of inspiratory muscle training in preventing or reversing diaphragmatic atrophy in mechanically ventilated COVID-19 patients.Materials and Methods: 55 intubated, mechanically ventilated patients with hypoxic respiratory failure due to COVID-19 were randomly assigned into study (n = 32) and control (n = 23) groups. The former received inspiratory muscle training with the routine physiotherapy programme and the latter received routine physiotherapy only. Diaphragmatic thickness was measured and compared in both groups using ultrasonography.Results: In the study group, diaphragmatic thickness at end of inspiration and expiration significantly increased by 14% and 8% respectively (p < 0.001). The increase in thickness fraction for this group (7.5%) was statistically insignificant (p > 0.05). In the control group, there was a significant decrease in all three parameters (p < 0.001).Conclusion: Inspiratory muscle training by adjusting the ventilator’s trigger sensitivity is a safe, effective and feasible method that can successfully prevent diaphragmatic atrophy in mechanically ventilated, COVID-19 patients. |
