The following explanation is discussed. Changing the patient's position may have lead to a compression of the inferior vena cava and thus to an increased collateral flow in the internal vertebral venous plexus. A bolus of local anesthetic, which had accumulated there due to sluggish blood flow, thereby may have been ejected from the venous plexus into the general systemic circulation.
