Epidural Space Depth Clinical Trial
Official title:
Ultrasound Guidance for Epidural Analgesia and Anesthesia
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.
