Epidural Space Depth
Conditions
Brief summary
Most women delivering by cesarean at BC Women's receive regional anesthesia; which includes spinal, epidural, or combined spinal-epidural anesthesia. In all these techniques a needle is placed in the lower back and local anesthetic is injected to freeze the body. Normally, before the needle is placed in a patients' back, the anesthesiologist will feel between their back bones with his/her fingers to find the right spot for the needle. This study will be evaluating if the distance from the skin to the appropriate spinal space measured with a novel 3D Ultrasound will equal the actual depth of the needle insertion.
Detailed description
The investigators will be evaluating if the distance from the skin to the appropriate spinal space measured with a novel 3D Ultrasound will equal the actual depth of the needle insertion.
Interventions
Parturients backs will be scanned using 3D ultrasound to measure the depth to the epidural space
