Overview
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.
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.
Eligibility
Inclusion Criteria:
- Age ≥18years and ≤80years;
- MV time ≤48h;
- MV duration is expected to be ≥72h;
- The sternocleidomastoid region and pectoralis major region were completely exposed.
- Patients or family members are willing to sign informed consent and participate in the study.
Exclusion Criteria:
- There are contraindications to PNS in vitro (Pneumothorax, active tuberculosis, pleural adhesions, installation of pacemakers and defibrillators, etc.);
- Neuromuscular disease (myasthenia gravis, etc.) or known anatomical abnormalities of the diaphragm;
- ECMO status;
- Hemodynamic instability;
- Uncorrected arrhythmias;
- Be pregnant;
- Clinical end-stage and palliative care patients.
