When performing an epidural blood patch, you may not be concurrently medically directing or supervising an anesthetist for any type of case.  The epidural blood patch is considered a procedure, similar to a surgeon performing an operation.  You are allowed to be the physician of record on a labor epidural that is running.  Be sure to hand off any cases you are currently on prior to the start time for an epidural blood patch.
