En jämförelse mellan respiratorisk polygrafi och perifer arteriell tonometri i diagnos av obstruktiv sömnapné

A comparison between Peripheral Arterial Tonometry and polygraphy in the diagnosis of Obstructive Sleep Apnea (English)
Abstract [sv]

Bakgrund: Obstruktiv sömnapné (OSA) är en av de vanligaste kroniska sömnsjukdomarna. Sjukdomen kännetecknas av återkommande episoder med andningsuppehåll under sömn. Detta ligger till grund för dagsömnighet och utveckling av systemsjukdomar. Det finna goda behandlingsalternativ för OSA som CPAP (continuous positive airway pressure), bettskena och kirurgi. Respiratorisk polygrafi (hädanefter presenterad som ”polygrafi”) är standardmetoden i Sverige för att diagnosticera OSA. Perifer arteriell tonometri (PAT) är en alternativ metod. Det finns olika kriterier för tolkning av polygrafi. Detta gör det svårt att jämföra studier. Svenska sömnapnéregistret (SESAR) och berörda specialitetsföreningar har därför tagit fram svenska nationella diagnoskriterier för sömnapné, SESAR-kriterierna. Syfte: Syftet med studien var att utreda om indexvärdena, AHI (apné-hypopné index) och ODI (oxygen desaturation index) överensstämmer i totalen och i olika positioner (rygg och icke-rygg) mellan PAT och polygrafi (tolkad med SESAR-kriterierna), samt att undersöka om det föreligger någon systematisk skillnad mellan dem. Material och metod: Elva patienter registrerades med polygrafi (NOX-T3) och PAT(WatchPAT) under en och samma natt. Registreringarna tolkades med SESAR kriterierna och WatchPAT scoring guidelines. Resultat: PAT visade en stark positiv korrelation med polygrafi (Spearman’s rho=0,771–0,963). Slutsats: Ingen signifikant skillnad hittades mellan PAT och polygrafi.

Abstract [en]

Background: Obstructive sleep apnea (OSA) is the most common chronic sleep disorder. The disease is characterized by recurrent episodes of respiratory arrest during sleep. This is the basis for daytime sleepiness and development of common systemic diseases. There are good treatment options for OSA including CPAP (continuous positive airway pressure), mandibular advancement splints and surgery. Respiratory polygraphy (hereinafter referred to as “polyhraphy”) is the standard method in Sweden for diagnosing OSA. Peripheral arterial tononometry (PAT) is an alternative method. There are different criteria for interpretation of polygraphy, thus making it difficult to compare studies. Svenska sömnapnéregistret (SESAR) and relevant speciality associations have therefore developed a Swedish national diagnostic criterion for sleep apnea, the SESAR-criteria. Purpose: To investigate if PAT and polygraphy (interpreted with the SESAR-criteria), correspond in apnea-hypopnea index (AHI) and oxygen desaturation index (ODI) and if there is any systematic difference between the methods in different positions (supine and non-supine). Material and methods: Eleven patients were registered with polygraphy (NOX-T3) and PAT (WatchPAT) for one night. The registrations were interpreted with the SESAR-criteria and the WatchPAT scoring guidelines, respectively. Results: PAT showed a strong positive correlation with polygraphy (Spearman’s rho=0,771-0,963). Conclusion: No significant difference was found between methods.
