Details and patient eligibility

About

The purpose of this study is to describe the diaphragm electromyographic activity (Edi) in healthy lung patients due to obtain a reference to guide the weaning in those patients

Full description

We obtained the Edi recording data at each NAVA level during the weaning in NAVA group, and we compared the respiratory parameters between the PSV and NAVA groups

Enrollment

40 patients

Sex

All

Ages

18 to 80 years old

Inclusion criteria

Patients who were scheduled for elective major surgery in which admission to the CCU (critical care unit) for postoperative care and short-term mechanical ventilation with rapid weaning were anticipated.

Exclusion criteria

Preoperative altered central nervous system, neuromuscular or lung disease and ASA (american society of anesthesiologists) classification group IV or NYHA (New York heart association) class IV in the case of cardiac patients. At the CCU, before randomisation, we also excluded patients requiring reoperation, and those who exhibited significant postsurgical bleeding, the development of myocardial infarction, and hemodynamic instability.
