Abstract:
ObjectiveTo investigate the feasibility,safety and efficacy of tracheal extubation with directly connected negative pressure suction. Methods86 patients with Ⅰ or Ⅱ degree of ASA,aged 18～65 years old,without history of respiratory disease,difficult airway and ventilation problems were involved in this study.All patients undergoing endotracheal general anesthesia were randomly divided into group A and B with 43 cases in each group.Group A used negative pressure directly connected to external side of the endotracheal tube before extubation.Group B used suction tube putting into the endotracheal tube before extubation.MAP,HR,ECG,SpO2,the condition of cough and expectoration and complicatons after extubation were recorded. ResultsIn group A the MAP,HR slightly increased,SpO2 slightly decreased,ECG showed no significant change,but the differences were not significant.In group B,MAP,HR,SpO2 showed significant difference compared with those before extubation and the corresponding period of group A. ConclusionsThe method that connecting negative pressure suction with endotracheal tube can effectively reduce the cardiovascular response during extubation,It also can avoid hypoxia,reduce the tracheobronchial injury and pulmonary complications.It's a practical good method in tracheal extubation.
