Methods: From 2019 to 2021, 64 patients with esophageal cancer underwent video-assisted thoracoscopic surgery in the same surgical treatment group. The pressure of CO<sub>2</sub> artificial pneumothorax was randomly divided into Group A (pressure 6 mmHg), Group B (pressure 8 mmHg), and Group C (pressure 10 mmHg). Heart rate (HR), mean arterial pressure (MAP), end-expiratory CO<sub>2</sub> partial pressure (PETCO<sub>2</sub>), arterial blood pH and PaCO<sub>2</sub>, operation time, intraoperative blood loss, and anesthesia resuscitation time were recorded at different time points. Observe the changes in inflammatory indexes, coagulation function, and the incidence of complications in the three groups, and statistically analyze and compare the differences among the three groups of patients. Results: Sixty-four patients with esophageal cancer were included in this clinical study. There were no significant differences in gender, age, lung function, BMI, and coagulation function among the three groups (P > 0.05). There were significant differences in PETCO<sub>2</sub>, arterial pH, and PaCO<sub>2</sub> in T2, T3, and T4 among the three groups (P < 0.05). The arterial blood gas index at T5 in Group A was significantly different from that in Group C (P < 0.05). The time of thoracic operation in Group A was significantly longer than that in the other two groups (P < 0.05), and the time of tracheal intubation and extubation was earlier in Group A (P < 0.05). The incidence of subcutaneous emphysema, thoracic tube time, and prothrombin time in Group A was significantly different from those in Group B and C (P < 0.05). There were no significant differences in hospitalization days, pulmonary infection, and other complications (P > 0.05). Conclusion: The artificial pneumothorax with 6 mmHg pressure and 8 L/min flow rate can satisfy the operation, and its safety and postoperative recovery are also better.展开更多

The patients of two groups were all given standard treatments with anti-tuberculous drugs. Treatment group received artificial pneumothorax to help the cure. Results showed that the frequency and quantity of drawing liquid in the treatment group were obviously less than those in the control group and the duration of the complete liquid absorption was shortened markedly in the treatment group and that total effective rate in treatment group (92.5%) was obviously higher than that of the control group (83.33%). We found that the artificial pneumothorax could raise the intra-pleural pressure by 0.20-0.39 kpa, reduce leakage in parietal pleurae and increase the absorption in visceral layer evidently. As it can isolate the two layers of pleurae from one another by the air in thorax, the incidence of pleurae adhesion can be decreased.展开更多
