-
Describe emergence phase
Anesthesiologist begins to awaken the patient from the anesthesia and extubation occurs for independent breathing
-
Describe recovery phase
Patient enters PACU, phase lasts until patient becomes fully responsive to commands
-
At what level is a spinal anesthetic administered?

Just outside the dura mater in the epidural space of the spine
-
Describe regional anesthesia
