There is no current evidence to guide the choice of epidural catheter placement level during labor. In fact, placement either at the higher or lower intervertebral spaces is often based only on provider preference. Therefore, the authors of the present study devised a single-blind, randomized controlled trial to test the hypothesis that epidural catheters placed at a low level require less rescue analgesia than catheters placed at a high level when using patient-controlled epidural analgesia (PCEA).
