Abstract
Background: In critically ill patients,physiotherapy and inspiratory muscle training are considered important components of pulmonary rehabilitation;as they enhance the weaning process and help patients to return to their optimal functional capacities. The aim of this work was to compare the possible benefits and risks of delivering multimodal physiotherapy (PT) to mechanically ventilated patients to improve patients’ outcome. Patients and Methods: Forty mechanically ventilated patients with acute or acute on top of chronic respiratory failure from ZUH (RICU) were enrolled in a randomized controlled clinical trial. The patients were classified equally into test group and control group, control group patients were subjected to conventional PT, while test group patients were subjected to inspiratory muscle training in addition to conventional PT. Pre and post assessment of SAPSII and Barthel index scores, PImax, RSBI and weaning outcomes were done for both studied groups. Results: Both patients’ groups were matched together as regards age, sex, ABG, diagnosis and comorbidities. The test group had a high significant lower frequency of conventional PT sessions in relation to control group 8 and 12 sessions respectively (P 0.05).There was high significant improvement in PImax post-PT in the test group when compared to control group (-34.3 6.02 cmH2O) versus (-24.6 2.45 cmH2O) respectively (P 0.05).The weaning success was (90% &70%) in test group versus control group, while the duration of MV, duration of weaning and length of ICU stay were significantly reduced in test group (5, 4.5 and 8.8 ± 2.22 days) versus control group (6, 6 and 11.95 ± 3.4.2 days), (P<0.05, P<0.01 and P<0.001), respectively. Conclusion: Conventional chest physiotherapy is safe ICU intervention with few complications. Adding inspiratory muscle training (using a threshold pressure device) to the conventional physiotherapy can improve maximum inspiratory pressure,functional capacity and RSBI, with potential reductions in length of ICU stay and the duration of invasive mechanical ventilation.
