During insertion of epidurals, the epidural space was identified with loss of resistance technique using normal saline; the obturator was removed, however, we were then unable to pass arrow catheter into the epidural space.A different catheter not in the kit is used and passes without difficulty.This has happened multiple times to a variety of anesthetists and physicians over the last 3-4 months.They feel the separate catheter has more flexibility than the catheter contained in the kit.No patient harm during any of the insertions; working with the vendor.Manufacturer response for epidural catheter kit, arrow epidural catheter kit (per site reporter): vendor working with us, gave us other catheters to use; took our info and experience back to their research and development team.
