Análise da colapsabilidade das vias aéreas superiores em pacientes com doença renal em estágio terminal

Abstract

Introduction: Currently, end stage renal disease (ESRD) is one of the most serious public health problems, becoming a global epidemic. It is also known that the amount of nocturnal rostral fluid displacement from the lower limbs is related to increased neck circumference and the severity of obstructive sleep apnea (OSA) in patients with end-stage renal disease. Method: A cross-sectional study was carried out to verify the degree of upper airway collapsibility in patients with ESRD. Negative expiratory pressure and baseline nocturnal polygraphy will be performed before and after the hemodialysis session. Results: There was a significant difference in pre and post hemodialysis in the various apnea / hypopnea index, neck circumference, waist circumference, percentage of exhaled flow at the time of 0.2 seconds (V0.2) sitting and lying down. The VO, 2 sitting pre-hemodialysis presented a correlation with the pre-AHI (p = 0.047, r = -0.953) and post hemodialysis (p = 0.010; r = -0.990). In addition, V0.2 after hemodialysis showed a correlation with AHI after hemodialysis (p = 0.029; r = -0.971). Discussion: The NEP test was promising for clinical use, since it has a rapid application and presents information relevant to the collapse of the airway of patients with suspected OSA.
