Early passive orthostatic training can prevent diaphragm atrophy and dysfunction in ICU patients on mechanical ventilation.
Background: Intensive care unit (ICU) patients on mechanical ventilation (MV), who are always bedridden, easily develop diaphragm atrophy and dysfunction. However, few studies have assessed diaphragmatic thickness and functional changes after early passive orthostatic training. Objectives: This is the first study to investigate the efficacy of early passive orthostatic training in preventing diaphragm atrophy and dysfunction in ICU patients on MV.Methods: In this randomized retrospective case-control study, 81 ICU patients on MV for 8 days or longer were enrolled. Forty-four patients received early passive orthostatic training initiated within 72 h of MV initi-ation (training group), and 37 patients did not receive training (no-training group). The protocol was per-formed for seven days, once a day for 30 min. The primary outcomes were diaphragmatic thickness and diaphragm contractile fraction (TFdi). The ventilatory parameters were secondary outcomes. Results: This study included 81 (45 male) ICU patients on MV [(mean +/- SD) age = (60.63 +/- 7.88) years]. The training group had a larger diaphragmatic thickness at end-expiration (Tdi,ee) and a smaller magnitude of decrease in Tdi,ee and TFdi (p = 0.001, 0.029, and <0.001, respectively) than the no-training group after 7 days of training. The mean arterial pressure, fraction of inspired oxygen, and white blood cell levels were decreased in the training group compared with the no-training group (p = 0.003, 0.001, and 0.026, respec-tively), but lactic acid levels decreased slightly in the training group with no significant difference (p = 0.708).Conclusions: Early passive orthostatic training is suitable to ameliorate diaphragm atrophy and dysfunction in ICU patients on MV.(c) 2023 The Authors.
