Is the Examination of a Single Night PolysomnographySufficient for a Diagnosis of OSAS in AdolescentPatients?

Abstract

Objective: The objective of the study was to evaluate the first night effect (FNE) on sleep architecture and respiratory pa rameters of adolescent patients with suspected obstructive sleep apnea syndrome (OSAS). Materials and Methods: A retrospective investigation was made of a total of 88 patients (51 males and 37 females, meanage 15.52±1.30 years, range 13–17 years) applied with polysomnography (PSG) because of suspected OSAS betweenMarch 1, 2016, and August 31, 2019. PSG was applied on two consecutive nights. The presence of OSAS was evaluatedseparately on the two consecutive nights and diagnostic accuracy was compared. Results: When the patients were investigated in respect of sleep architecture, there was seen to be a significant differencebetween the two nights in the values of total sleep time (min) (p=0.001), time in bed (min) (p=0.001), sleep latency (min)(p=0.001), and rapid eye movement (REM) latency (min) (p
