Assessment of Airway Changes During Pregnancy With Ultrasonography and Clinical Airway Screening Tests: A Prospective Observational Study

Abstract

Introduction: Ultrasonographic airway assessment is a promising adjunct to predict difficult intubation; however, it has been relatively less studied in obstetric cases. This study aimed to assess the progress of anatomical changes in the obstetric airway, through all the three trimesters, using ultrasound measurements and clinical screening methods.
