Protective Effect of Electroacupuncture on Lung in Patients Undergoing General Anesthesia

Objective to investigate the protective effect of preoperative electroacupuncture on lung function in patients with mechanical ventilation for more than 2 hours under general anesthesia

Randomized parallel control study. From September 1, 2021 to December 31, 2022, patients with mechanical ventilation time more than 2 hours will be randomly divided into electroacupuncture pretreatment group and blank control group. The blood gas index, ventilator parameters and serum inflammatory factor concentration of patients will be evaluated to evaluate whether electroacupuncture has protective effect on lung function of patients with mechanical ventilation.
