About this trial
The aim of this study is to evaluate the use of the sagittal abdominal diameter (SAD) as a potential predictor of the skin to epidural space distance (SESD) and to compare its accuracy versus that of the BMI as a previously validated predictor

Treatments tested in this trial
Epidural block
Procedure/SurgeryEpidural catheter will be inserted at the L3-L4 or L4-L5 interspace in obese subjects scheduled for surgery on the lower extremities under epidural anesthesia. The sagittal abdominal diameter, BMI and skin to epidural space distance will be recorded.

Trial outcomes
Primary outcomes
1
Accuracy of the sagittal abdominal diameter for prediction of the skin to epidural space distance
Actual skin to epidural space distance will be determined and regressed on the sagittal abdominal diameter to determine accuracy of the latter for prediction of the former
Time frame
18 monthsSecondary outcomes
1
Accuracy of the BMI for prediction of the skin to epidural space distance
Actual skin to epidural space distance will be determined and regressed on the BMI to determine accuracy of the latter for prediction of the former
