A prospective randomized controlled study included 104 patients with MV who met inclusion criteria in multiple hospital ICU units and were randomly divided 1:1 into PNS and conventional groups. The PNS group received neuromuscular electrical stimulation in addition to routine airway management, early activity and respiratory muscle training. It was verified that early non-invasive PNS could increase the number of days without mechanical ventilation for 28 days, delay disused diaphragm atrophy and improve inspiratory muscle strength.
the early application of non-invasive PNS in MV patients can increase the number of days without mechanical ventilation, delay disuse phrenic atrophy, and improve the strength of inspiratory muscle.
