ABSTRACT
Introduction: the diaphragm is the main respiratory muscle and its dysfunction in critically ill patients favors the development of respiratory complications, thereby increasing the days of mechanical ventilation.
Objective: to determine the correlation of diaphragmatic function measured by ultrasound in comparison with negative inspiratory force (NIF), as predictors of ventilatory weaning in critically ill patients in the Intensive Care Unit.
Material and methods: comparative study of diagnostic accuracy, observational, longitudinal, prospective, diaphragmatic excursion was measured with ultrasound upon admission and daily until withdrawal of mechanical ventilation; additionally, time to peak inspiratory amplitude of the diaphragm (TPIA) and NIF was measured. Withdrawal was considered successful when ventilatory support was not required again for a period of 48 hours.
Results: 50 patients were included: surgical and non-surgical neurological 23 (46%), non-cardiothoracic post-surgical 11 (22%), infectious nine (18%), cardiothoracic post-surgical five (10%) and primary respiratory disorders two (4%). Spontaneous ventilation test with T-piece was performed in 49 (98%) patients and CPAP/PS in one (2%). Success at removal was reported in 44 (88%) patients. Measurement of diaphragmatic excursion prior to extubation, AUC of 0.8 (p = 0.009), cut-off point to predict successful extubation was 1.09, sensitivity of 97.7%, specificity of 83.3%; TPIA, AUC 0.79, cut-off point 0.81 seconds, p = 0.002, sensitivity of 79.5% and specificity 83.3%; NIF, AUC 0.48, cut-off point -23.5, p = 0.9, sensitivity 27.3%, specificity 33.3; Tobin/Yang index, AUC of 0.32, cut-off point 79, p = 0.2, sensitivity 18%, specificity 66.7%. Correlation coefficient of admission diaphragmatic excursion of 0.23, p= 0.1, diaphragmatic excursion at 48 hours of 0.81, p = 0.001, TPIA of 0.9, p = 0.001.
Conclusion: both diaphragmatic excursion and the time to reach the peak inspiratory amplitude of the diaphragm, measured by ultrasound, present adequate sensitivity and specificity to predict successful extubation in the critically ill patient compared to negative inspiratory force.
