摘要气管插管全身麻醉是目前临床主要的全麻方式，然而气管插管会导致声带损伤等相关并发症，用于短小手术时手术周转效率低。将经鼻湿化快速充气交换通气技术和新型肌松拮抗剂结合，即经鼻高流量支持下无气管插管深肌松麻醉(H-NIDP)，可以解决这一临床问题。该方法目前尤其适用于部分咽喉部短小手术。为进一步推广H-NIDP，中国心胸血管麻醉学会创新与推广分会组织专家制定了首部H-NIDP专家共识，该共识介绍了H-NIDP的应用范围、相关实施细则等规范。该共识虽历经专家反复修改讨论，但不足之处在所难免，欢迎读者提出意见和建议，以便进一步更新。

abstractsGeneral anesthesia with tracheal intubation is currently the most widely used anesthesia strategy. But it would still inevitably cause related complications, including vocal cord injury, blood pressure fluctuations, etc. The turnaround efficacy of surgery is low when it is used for minor surgeries. A new anesthesia strategy, which combined with transnasal humidified rapid insufflation ventilatory exchange and a new type of muscle relaxant antagonist, called non-intubated deep paralysis with high-flow nasal oxygen (H-NIDP), can solve this clinical problem. This strategy is particularly suitable for some minor surgeries in the throat. In order to further promote the H-NIDP technology, Chinese Society of Cardiothoracic Anesthesiology on Promotion Society of New Anesthesia Technology organized experts and made up a task force to formulate the first " expert consensus on non-intubated deep paralysis with high-flow nasal oxygen" . This consensus introduces the application scope of H-NIDP technology and formulates relevant implementation rules and specifications. Although the consensus has been repeatedly revised and discussed by experts, deficiencies are inevitable. Readers are welcome to provide opinions and suggestions for further updates in the future.
