Effects of electrical stimulation neuromuscular on mobility critical patients diaphragmatic in mechanical ventilation invasive: randomized controlled trial

Abstract

Introduction: Muscle weakness is one of the problems in patients with invasive mechanical ventilation, and in order to mitigate this comorbidity Neuromuscular Electro-stimulation (NMES) has been studied. Objectives: to verify the effects of NMES on diaphragmatic mobility and its association with accessory breathing muscles in critically ill patients. Methods: Randomized clinical trial (RCT), 24 mechanically ventilated patients, randomized into: intervention (G1) and placebo (G2). NMES applied 1 time / day, 30 minutes, in the pectoral and recumbent abdominal muscles using ultrasound for analysis of thickness. Results: significant difference (G1) in expiratory diaphragmatic mobility (p = 0.015), direct correlation between abdominal and pectoral rectus (rs = 0.607 and p = 0.048), abdominal rectus and diaphragmatic incursion (rs = 0.609 and p = 0.047), as well as (rs = 0.920 and p <0.001) and diaphragmatic excursion and diaphragmatic thickness (rs = 0.607 and p = 0.048). Conclusion: In this sample there was improvement in diaphragmatic mobility and correlation between studied muscles, suggesting preservation of the diaphragmatic mobility in the electrostimulated group.
