Mallampati class change has not been well evaluated during the cesarean delivery. Various factors regarding to cesarean delivery might influence this changes. The aim of this study was to evaluate the Mallampati class before and after cesarean delivery and to identify predictive factors of the changes..
Study Type: Observational Cross-sectional study
Mallampati class, thyromental distance, neck circumference, and upper lip bite test were evaluated at four time intervals : during pre-anesthetic visit (T0), 1-hour (T1), 6-hour (T2), and 24-hour after delivery (T3).
