[Expert consensus on the clinical application of inhaled nitric oxide in the perioperative period of adult surgical procedures (2026 edition)].

Nitric oxide is a selective pulmonary vasodilator. In recent years, inhaled nitric oxide (iNO) has garnered significant attention for its application in adult perioperative care. To standardize its application during the adult perioperative period, the Chinese Society of Anesthesiology of Chinese Medical Association, the Critical Care Branch of Beijing Perioperative Medicine Study Society, the Critical Care Medicine Branch of Beijing Medical Association, and National Alliance of Geriatric Anesthesiology have jointly developed the"Expert consensus on the clinical application of inhaled nitric oxide in the perioperative period of adult surgical procedures (2026 edition)"based on Chinese clinical practice and the latest research advances. This consensus document addresses key aspects of iNO use in the adult perioperative setting, including dosing range, clinical benefits, equipment setup, patient assessment, and safety monitoring. The consensus presents 11 recommendations, aiming to standardize and enhance clinical understanding and practical competency regarding iNO therapy among relevant disciplines. This document serves as a guidance reference for the clinical use of iNO in the perioperative management of adult surgical patients.
