Transcutaneous Diaphragm Stimulation in ICU Patients

Sponsor: Karadeniz Technical University

Summary

The aim of this study is to compare the effects of transcutaneous electrical diaphragm stimulation (TEDS) on diaphragm thickness, duration of mechanical ventilation, length of ICU stay, and right/left heart functions between patient groups with low and high ejection fraction (EF) levels. This randomized controlled trial will record demographic data, diaphragm ultrasound measurements, and echocardiographic findings of patients who receive or do not receive TEDS for five consecutive days. Participants will be divided into four groups according to their EF levels and whether or not they receive diaphragm stimulation: Group 1: Patients with low EF who receive TEDS Group 2: Patients with high EF who receive TEDS Group 3: Patients with low EF who do not receive TEDS Group 4: Patients with high EF who do not receive TEDS Diaphragm thickness and echocardiographic assessments will be performed at baseline and at the end of the five-day TEDS intervention. TEDS Application Protocol In the ICU, TEDS is administered by a physiotherapist once daily for 20 minutes, five days a week, as part of the routine treatment protocol. The stimulation is delivered using the LGT-231 model device from the LONGEST brand. A transcutaneous current with a frequency of 30-50 Hz and a pulse width of 300-400 microseconds is applied to the diaphragm. The stimulation intensity is increased until visible muscle contraction is achieved. Electrode placement involves: The first pair of electrodes placed bilaterally between the 8th and 10th anterior intercostal spaces, lateral to the xiphoid process. The second pair placed along the mid-axillary line of the thorax, also between the 8th and 10th intercostal spaces.
