NCT05629819

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.

Study Arms (2)

PNS group

EXPERIMENTAL

In addition to conventional respiratory therapy and pulmonary rehabilitation, neuromuscular electrical stimulator was used for PNS * Device Settings Strength: Maximum current tolerated by the patient (0-100mA, commonly used below 13mA) ; Stimulation time: 1.0s; Frequency: 40Hz; * Location: The stimulation electrodes were attached to the left and right sides of the neck under the outer margin of the sternocleidomastoid muscle 1/3; The reference electrodes were attached to the surface of both pectoralis major muscles. * Treatment frequency: 30 at a time, Bid, until withdrawal/death/for 4 weeks.

Device: Non-invasive phrenic nerve stimulation

conventional group

NO INTERVENTION

* conventional respiratory therapy and pulmonary rehabilitation, including airway management, early activity, and respiratory muscle training. * No intervention

Interventions

Some studies have shown that PNS can relieve diaphragmatic atrophy and reverse diaphragmatic dysfunction.
