Clinical effect of pulmonary rehabilitation combined with diaphragm pacemaker therapy in the treatment of severely ill patients with mechanical ventilation.

To investigate the effect of pulmonary rehabilitation combined with diaphragm pacemaker therapy on the diaphragm function of severely ill patients on mechanical ventilation. Forty patients were randomly divided into the control group (CG; n = 20) and experimental group (EG; n = 20). The CG was given basic ICU nursing and conventional rehabilitation treatment. The EG added a diaphragm pacemaker and pulmonary rehabilitation therapies along with basic ICU nursing and conventional rehabilitation treatment. The relevant indexes were compared at baseline and postintervention, including the Glasgow Coma Scale (GCS), Acute Physiology, Chronic Health Evaluation II (APACHE II) scores, diaphragm mobility and thickness. The indexes of mechanical ventilation time, ICU and total hospital stays were compared between the two groups. There was no difference in the GCS and APACHE II scores, and diaphragm mobility and thickness between the two groups before treatment (P > 0.05). After 30 days of treatment, the GCS scores increased in both groups, the APACHE II scores decreased significantly, and diaphragm mobility and thickness decreased compared with before treatment (P < 0.05), but the improvement of each index in the EG was more evident than in the CG. Compared with the CG, the indexes of the EG, including offline, ICU and total hospitalization times, were significantly shorter (P < 0.05). Additionally, there were no adverse events such as accidental tube detachment or falling out of bed during treatment. Pulmonary rehabilitation combined with a diaphragm pacemaker is safe and effective in treating severely ill mechanically ventilated patients.
