The use of STOP-BANG questionnaire and other difficult airway determinants in difficult airway prediction and correlation

BACKGROUND: The primary objective of this study was to evaluate the use of STOP-BANG questionnaire in prediction of difficult airway. The secondary aim of this study is to evaluate the correlation of the questionnaire and other difficult airway determinant tests in predicting difficult airway.
METHODS: Two hundred American Society of Anesthesiologists’ Status I, II, and III patients under general anesthesia were enrolled in this prospective randomized study. Patients’ age, height, body weight, body mass index, neck circumference, inter-incisor distance when the mouth is fully open, sternomental and thyromental distance, mandibular length, neck length, biting the upper lip, STOP-BANG score, and Mallampati and Cormack–Lehane (C–L) grades were recorded. The first thing we want to find is to determine the usability of the STOP-BANG questionnaire as an indicator of the difficult airway. Comparing difficult airway with the other parameters was secondary objectives. The patients were divided into two groups as difficult and easy intubation with difficult and easy facial mask ventilation. The data were analyzed using an SPSS statistics 16.0 program. Statistical analysis was performed using, Chi-square and Spearman correlation analysis test.
RESULTS: Forty-five out of 200 patients had difficulty in intubation and 73 out of them had difficulty in mask ventilation. Between difficult airway and high STOP-BANG score was a moderate positive correlation (p<0.05). Furthermore, unnatural dental status, greater head circumference, greater neck circumference, Mallampati, and C–L classification were significantly positive correlated with a difficult airway (p<0.05).
CONCLUSION: In our study, the STOP-BANG questionnaire was found to be important in predicting the difficult airway and this test was found to be usable like other difficult airway parameters.

Zor havayolu tahmini ve korelasyonunda STOP-BANG anketinin ve diðer zor havayolu belirleyicilerinin kullanýlmasý

AMAÇ: Bu çalýþmadaki ilk amaç, zor hava yolunu tahmin etmede STOP-BANG anketinin kullanýmýný deðerlendirmektir. Çalýþmada ikincil olarak deðerlendirmek istenen zor hava yolunu tahmin etmede anketin ve diðer zor hava yolu belirleyici testlerin korelasyonunu deðerlendirmektir. GEREÇ VE YÖNTEM: Bu ileriye yönelik randomize çalýþmaya genel anestezi altýnda opere olacak iki yüz Amerikan Anesteziyologlar Derneði (ASA) skoru I, II ve III olan hastalar alýndý. Hastalarýn yaþý, boyu, vücut aðýrlýðý, vücut kitle indeksi, boyun çevresi, aðýz tam açýkken interinsizör mesafesi, sternomental ve tiromental mesafe, mandibular uzunluk, boyun uzunluðu, üst dudak ýsýrma testi, STOP-BANG skoru, mallampati ve Cormack Lehane derecesi notlarý kaydedildi. Ýlk olarak bulmak istediðimiz zor hava yolunun bir göstergesi olarak STOP-BANG anketinin kullanýlabilirliðini tespit etmektir. Zor hava yolunu diðer parametrelerle karþýlaþtýrmak ikincil hedefimizdi. Hastalar zor ve kolay yüz maskesi ventilasyonu ile zor ve kolay entübasyon olarak iki gruba ayrýldý. Veriler bir SPSS istatistik 16.0 programý kullanýlarak analiz edildi. Ýstatistiksel analiz Ki-kare ve Spearman korelasyon analizi testi kullanýlarak yapýldý.
BULGULAR: Ýki yüz hastadan 45’inin entübasyonda, yetmiþ üçünün ise maske ventilasyonunda zorluk görüldü. Zor hava yolu ile yüksek STOP-BANG skoru arasýnda orta derecede pozitif korelasyon vardý (p<0.05). Ayrýca anormal diþ yapýsý, büyük kafa çevresi, büyük boyun çevresi, mallam-pati, Cormack Lehane sýnýflandýrmasý zor hava yolu ile anlamlý pozitif korelasyon gösterdi (p<0.05).
TARTIÞMA: Çalýþmamýzda, STOP-BANG anketinin zor hava yolunu tahmin etmede önemli olduðu görülmüþtür ve bu test diðer zor hava yolu parametreleri gibi kullanýlabilir olduðu tespit edilmiþtir.
