Abstract:Objective To study the feasibility of small-sized left-sided double-lumen tube for thoracic surgery anesthesia when combined with low tidal volume ventilation. Methods From October 2016 to February 2017, 30 cases of thoracic surgery patients with a single lung ventilation in the left-sided double-lumen tube in Nanjing First Hospital were selected as research objects, and divided into two groups by random number table, with 15 cases in each group. Patients of two groups were treated with different size left-sided double-lumen tubes. The trial group (group T) was applied to the small model, male application F35, female application F32. Control group (group C) was applied to the normal model, male application F37, female application F35. The resistance during intubating, airway trauma testified through fiberoptic bronchoscopy, intubation attempts and hemodynamic changes following intubation were compared between two groups. The airway peak-pressures at the beginning of double-lung ventilation following successful intubation and one-lung ventilation, together with the airway peak-pressure after one-hour′s one-lung ventilation, the oxygen saturation (SPO2) after one-hour′s one-lung ventilation were also compared between two groups. The lowest mean arterial pressure (MAP) and corresponding heart rate (HR) before intubation, the highest MAP and corresponding HR after intubation were recorded. The deviation value between the highest MAP and the lowest MAP, together with the corresponding deviation value of HR, were also compared between group T and group C. Results The resistance during intubating, airway trauma testified through fiberoptic bronchoscopy in group T were lower than those of group C, with statistically significant difference (P < 0.05). There was no statistical difference between two groups in intubation attempts (P > 0.05). During mechanical ventilation, there was no statistical difference between two groups in the double-lung ventilation following successful intubation, one-lung ventilation together with the airway peak-pressure after one-hour′s one-lung ventilation, SPO2 after one-hour′s one-lung ventilation (P > 0.05). In addition, the increased value of HR caused by intubation was less in group-T than in group C (P > 0.05) and the increased value of MAP was also less in group T than in group C (P > 0.05). Conclusion Small-sized left-sided double-lumen tube can satisfy the need of one-lung ventilation when combined with low tidal volume ventilation, and the respiratory tract injury caused by tracheal intubation was more stable.
