ABSTRACT
Objective: The aim of the study was to evaluate the sleep depth of patients at the minimum oxygen saturation (minSO2) level and the level of airway obstruction during drug-induced sleep endoscopy (DISE). To also evaluate the effects of polysomnography (PSG) and DISE findings on surgical planning and patient outcome. Material and Methods: Analysis of patients who presented with Obstructive Sleep Apnea Syndrome between July 2017-and-December 2019 was performed in a tertiary referral hospital. With a Bispectral Index (BIS) monitoring, the sleep depth of the patients at the level of airway obstruction detected during DISE and at minimum oxygen saturation (minSO2) was recorded by Bispectral Index (BIS) monitoring. Clinical characteristics, PSG results, physical examination, and DISE findings were assessed. Results: Obstruction was most common in the retropalatal region in patients who underwent DISE. The BIS values during the minSO2 of all patients during DISE ranged from 41-80, with an average of 59.76±7.21. The BIS values during snoring were between 38-85, with an average of 70.94±8.00. The BIS value during obstruction ranged from 38-85, with an average of 61.58±7.00. Conclusion: DISE is a valuable diagnostic tool for examining the upper airway during sedation mimicking sleeping, to identify structures that contribute to airway obstruction. Our study showed that as the sleep depth of the patients changes, the level and degree of obstruction detected in DISE will change. Therefore, it is important to evaluate the patients in the sleep depth closest to physiological sleep during DISE.
ÖZET
Amaç: Çalışmanın amacı, ilaçla indüklenen uyku endoskopisi [drug-induced sleep endoscopy (DISE)] sırasında hastaların minimum oksijen satürasyon düzeyindeki ve hava yolunda obstrüksiyon saptanan seviyedeki uyku derinliğini değerlendirmektir. Polisomnografi (PSG) ve DISE bulgularının cerrahi planlama ve hastanın sonucu üzerindeki etkilerini de değerlendirmektir. Gereç ve Yöntemler: Temmuz 2017-Aralık 2019 arasında obstrüktif uyku apne sendromu ile başvuran hastaların analizi üçüncü basamak bir sevk hastanesinde yapıldı. Hastaların DISE sırasında hava yolunda obstrüksiyon saptanan seviyede ve minimum oksijen satürasyonu [minimum oxygen saturation (minSO2)] sırasındaki uyku derinliği Bispektral İndeks [Bispectral Index (BIS)] monitörizasyonu yapılarak kaydedildi. Hastaların klinik özellikleri, PSG sonuçları, fizik muayene bulguları ve DISE bulguları değerlendirildi. Bulgular: DISE sırasında hastalarda en çok saptanan obstrüksiyon seviyesi, retropalatal bölge olarak izlendi. DISE sırasında hastaların minimum oksijen satürasyon seviyesindeki BIS değerleri, ortalama 59,76±7,21 ve 41-80 arasında değiştiği izlendi. Horlama sırasındaki BIS değerleri 38-85 arasında değişmekte ve ortalama 70,94±8,00 idi. Obstrüksiyon sırasında BIS değerleri 38-85 arasında değişmekte olup ortalama 61,58±7,00 idi. Sonuç: DISE, uykuyu taklit eden sedasyon sırasında üst solunum yolunu muayene etmeyi sağlayan ve hava yolu obstrüksiyonu izlenen seviyeyi saptamaya yarayan bir tanı yöntemidir. Çalışmamız hastaların uyku derinliği değiştikçe DISE’de saptanan obstrüksiyon düzeyi ve derecesinin değişeceğini göstermiştir. Bu nedenle DISE sırasında fizyolojik uykuya en yakın uyku derinliğinde değerlendirilmesi önemlidir.
