“…We found that ULBT classes showed an increasing trend with the progression of labor. Approximately one-fifth of the parturients experienced an increase in ULBT classes after delivery, which was lower than the 66.7% increase observed in the Mallampati class, as observed by Raza and Ismail ( 15 ). The proportion of parturients with ULBT classes 2–3 increased by 48% compared with early labor and the incidence of ULBT class 3 after delivery was 4.5% on average.…”

BackgroundThe difficult airway (DA) assessment and management of pregnant woman has always brought specific challenges. The aim of this study was to investigate the effect of labor on the airway by assessing changes in the upper lip bite test (ULBT) classes and to explore its correlation with the first trimester's body mass index (BMI).MethodsAccording to the BMI of the first trimester, 354 full-term women were divided into low BMI group, normal BMI group and high BMI group. The ULBT class and pregnancy outcome were recorded and compared at early labor, after delivery, and 48 h after delivery.ResultsThe ULBT class was increased in 75(21.1%) patients after delivery. Compared to the normal BMI group, the high BMI group had a higher probability of increasing (34.8 vs. 17.5%; P = 0.002). The number of women with ULBT class 2–3 increased to 157, which was 1.48 times that of early labor. The number of women with ULBT class 3 increased from 4 to 16, of which 7 (53.8%) were from the high BMI group. Binary logistic regression analysis showed that first trimester's BMI was associated with a significant increase in ULBT class after delivery (adjusted odds ratio [aOR] = 2.13 [0.91–4.98], P = 0.02). The ULBT classes of the three groups tended to return to their initial level 48 h after delivery (P > 0.05).ConclusionLabor results in an approximately one-fifth increase in ULBT class. Being overweight or obese in the first trimester is associated with an increased risk of DA during labor.Trial registrationThis study was registered in the Chinese Clinical Trial Registry (http://www.chictr.org.cn) on September 26, 2020. Registration number ChiCTR2000038643.

“…Although anaesthesiologists have been using predictors of difficult airway ( 10 ), there is little evidence to help predict the difficulty at epidural insertion for labouring parturient women. In the present study, we attempted to identify the predictors of difficult labour epidural placement in full-term parturient women.…”

Change in Mallampati class during labor: Hypertensive versus normotensive parturients

Abstract: Mallampati class showed 2-fold increase in hypertensive compared to normotensive parturients during labor; requiring additional caution during airway management.
