PACU
Pronunciation: PACK-you
Also written as: PACU — Post-Anesthesia Care Unit
Post-Anesthesia Care Unit, the specialized recovery area where patients are monitored immediately following emergency surgery until they meet discharge criteria.
Full Definition
The Post-Anesthesia Care Unit (PACU) is a specialized nursing unit designed for the immediate postoperative care of patients recovering from anesthesia and surgical procedures. In emergency surgery settings, PACU serves as a critical transition point where patients are closely monitored for complications related to anesthesia emergence, pain management, and early surgical complications. PACU nurses are specially trained to recognize and manage common postoperative issues including airway obstruction, hemodynamic instability, emergence delirium, and inadequate pain control. Patients typically remain in PACU until they meet specific discharge criteria including stable vital signs, adequate pain control, and return of protective reflexes. For emergency surgery patients, PACU stay may be prolonged due to hemodynamic instability or the need for continued intensive monitoring before transfer to appropriate inpatient units.
