Brief summary
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.
Detailed description
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.
Interventions
Some studies have shown that PNS can relieve diaphragmatic atrophy and reverse diaphragmatic dysfunction.
