简要总结
Pregnant women, with a Body Mass Index (BMI) greater than 30 kg/m2, who receive epidural analgesia/anesthesia for childbirth will have epidural catheter placement per our standard procedure, which includes using the gravity flow technique to confirm that the tip (aperture) of the epidural needle is indeed located within the epidural space. The study procedure will be to use a cold stimulus (ice) to assess the subjects for hypesthesia the dermatomes of the lower abdomen between 10 and 30 minutes after the epidural catheter is inserted. Hypesthesia to cold will be taken a sign of successful lumbar epidural block.
详细描述
The purpose of this study is to quantify the reliability of the gravity flow technique to accurately validate the position of the epidural needle tip when performing lumbar epidural analgesia/anesthesia for childbirth (vaginal and cesarean delivery) in women with a BMI greater than 30 kg/m2.

结局指标
主要结局
Measure of bilateral decrease of sensation to cold with ice
时间窗: 30 Minutes Post Intervention
Loss of sensation to ice; Following epidural procedure, subjects will be assessed to see if their epidural analgesia is working by determining if they have hyperthesia to ice on lower abdomen.
