Small-diameter Closed Thoracic Drainage Tube Fixation Method

Objective: To explore the design feasibility and application effect of triple-buffer-system-fixed small-diameter (18 F) thoracic closed drainage tubes following lung wedge resection. Methods: A total of 136 patients with indwelling thoracic drainage tubes following pulmonary wedge resection were recruited, with 70 patients allocated to the control group and 66 to the experimental group. The drainage tube in the experimental group was fixed with the triple-buffer system, while that in the control group was fixed using the conventional lifting platform method. The incidence of unplanned extubation, the indwelling time of the drainage tube and the time and material costs, as well as information regarding any subcutaneous emphysema and skin tension blisters, were recorded following the operation. The pain and degree of comfort were assessed using a chi-square test and a rank sum t-test to compare the differences between the two groups.

Inclusion Criteria:Single-port thoracoscopic wedge resection of the lung was performed for the first timeNo air leak in the lung tissue was detectedThe patient could communicate and cooperate normally.No local skin allergy or scar could be observed.Exclusion Criteria:Patients with wide adhesion of the whole thoracic mucosa.Patients with postoperative or intraoperative bleeding.Patients with severe postoperative hypoproteinaemia or chylothorax with massive pleural effusion.Patients diagnosed with emphysema.
