Anesthesiologists order epidural infusions which are prepared by pharmacy and administered by nurses trained in epidural infusion pumps. Nurses maintain and modify infusion rates as ordered, can administer bolus doses up to 10ml, and must change tubing every 72 hours and solutions every 24 hours. Blood thinners are not used or given when a patient has an epidural in place due to risk of bleeding. Nurses should address any side effects by following protocols before contacting anesthesia.
