title: The influence of obesity on the relationship between body mass index and the distance to the epidural space from the skin.
abstract: This study confirms that distance to the epidural space from the skin at the L3-4 interspace is only moderately correlated with body mass index in obstetric patients. A similar moderate linear correlation was found in the non-obstetric patients. However, in obese patients (BMI > 25), distance to epidural space from the skin correlated poorly with body mass index.
