Perioperative Nursing

🏥 Perioperative Nursing

Perioperative nursing encompasses the comprehensive care provided before, during, and after a surgical procedure. It integrates physiologic assessment, legal and ethical preparation, intraoperative safety monitoring, anesthesia management, and postoperative complication surveillance. Nurses serve as patient advocates, safety guardians, and early detectors of hemodynamic or respiratory instability. Effective perioperative management reduces surgical morbidity, prevents sentinel events, and promotes optimal recovery outcomes. Strong clinical anticipation and systematic assessment are essential in ensuring patient safety across all surgical phases.
