There is a paucity of evidence-based clinical research on safe maximal daily chest tube drainage prior to removal. Objectives: To describe the practice patterns of Canadian thoracic surgeons with respect to daily chest tube drainage after routine pulmonary surgery. Methods: A self-reported electronic questionnaire was administered to members of the Canadian Association of Thoracic Surgeons (CATS). Data was tabulated on the primary outcome of acceptable maximal daily pleural output prior to chest tube removal, and secondary outcomes of: years in clinical practice, academic versus community setting and rational for chest tube management. Descriptive and univariate analysis was conducted for each response by maximal daily pleural drainage category. Results: A total of 124 surveys were distributed. Response rate was 56%, with a 93% completion rate. Acceptable maximal pleural drainage among surgeons was highly variable. Rationale for tube removal was also variable, including individual clinical experiences (n = 23, 33%), evidence based guidelines (n = 18, 26%), and group practice pattern (n = 12, 17%). Academic surgeons comprised 72% of respondents. Community based surgeons were more likely to remove tubes at a lower mean volume. Years in clinical practice did not influence acceptable daily pleural drainage. Conclusion: There is great variability in post-operative management of chest tube fluid output among Canadian thoracic surgeons. Future research on this topic is warranted, with the aim of developing an evidence-based chest tube management algorithm incorporating daily chest tube drainage volumes as a key variable.展开更多

Unfortunately, there are few reports about the complications caused by position change of the chest tube until now. We presented an unusual case of a patient who underwent a transthoracic operation for esophageal cancer in our department on August 17, 2006, and a lot of intragastric material was found in his chest tube 17 days later, endoscopic examination suggested that the chest tube had inserted into the stomach. We tried to discuss the etiology and clinical management for this case as well.展开更多

Focus was placed on identifying the hemothorax size requiring tube thoracostomy.RESULTS A total number of 274 hemothoraces were studied. All patients with hemothoraces measuring above 3 cm received a chest tube. The 50% predicted probability of tube thoracostomy was 2 cm. Pneumothorax was associated with odds of receiving tube thoracostomy for hemothoraces below 2 cm(Odds Ratio:4.967, 95%CI: 2.225-11.097, P < 0.0001).CONCLUSION All patients with a hemothorax size greater than 3% underwent tube thoracostomy. Prospective studies are warranted to elucidate the clinical outcome of patients with smaller hemothoraces.展开更多

In each case, simple auscultation was used to guide SB tube insertion, with chest radiograph obtained only after complete inflation of the gastric balloon. Two patients died of hemorrhagic shock and one died of mediastinitis.The author suggests that confirmation of SB tube placement by auscultation alone may not be adequate.Routine chest radiographs should be obtained before and after full inflation of the gastric balloon to confirm tube position and to detect tube dislocation.展开更多

We propose a new approach for inserting tube thoracostomies to improve the safety of this procedure, termed guided blunt dissection. In this article, we compared the safety of this new approach with traditional blunt dissection and two commercially available Seldinger tube thoracostomy kits in an ex vivo model. Methods: We recruited 32 clinicians from a variety of medical specialties with a range of experience in performing tube thoracostomy. Each clinician was required to perform tube thoracostomy using all four approaches in a randomised order. Objectively, each insertion was categorised as “safe” if the lung remained intact and “unsafe” if the lung deflated. Subjectively, participants were asked to rank each approach in order of perceived safety on a four-point scale. Statistical analysis was performed using a Fisher’s exact test. Results: Objectively, guided blunt dissection was significantly safer than both Seldinger approaches (p 0.0001), but not traditional blunt dissection (p = 0.71). Subjectively, none of the approaches were felt to be superior. Conclusions: These data support the conclusions that, in this ex vivo model, the new guided blunt dissection approach provided a safe method for tube thoracostomy. Guided blunt dissection produced less lung deflations relative to competing methods, certainly when compared objectively to Seldinger techniques. Of note, the Seldinger approaches were perceived by the participants to be as safe despite there being an increased incidence of lung injury associated with their use in this model. This indicates that it was not always possible for the clinician to determine when lung injury had occurred. This potential for lung injury when using Seldinger approaches for tube thoracostomy should be emphasised.展开更多
