Filter by:The management of spontaneous large pneumothorax is not consensual. The current management involves the establishment of a Fuhrman catheter and an outpatient monitoring in pneumology consultation. Another alternative is widespread: simple exsufflation. However, no study has looked at the direct prospective comparison of these 2 treatments.
Lung cancer is the deadliest of all cancers, and its incidence is on the rise. The importance of accurate and efficient lung biopsy without complications will only increase in importance going forward. Pneumothorax is a common complication of CT-guided lung biopsy. The purpose of this study is to assess the efficacy of using Gelfoam slurry in preventing pneumothorax from lung biopsy in a randomized controlled trial. Gelfoam (Pfizer, New York, NY, USA) is gelatin product approved by the Food and Drug Administration (FDA) for hemostasis during various procedures. In the study group, the needle track will be laced with Gelfoam slurry following biopsy, and will be compared to standard lung biopsy without any other interventions. Both groups will be followed up with chest x-ray for pneumothorax.
The investigators evaluate the effect of postural change on the bronchial cuff pressure (BCP) of double-lumen endotracheal tube (DLT) in patients undergoing thoracic surgery, by observing the pressure of the bronchial cuff before and after lateral decubitus positioning.
Primary spontaneous pneumothorax (PSP) defines as presence of air in chest cavity occurs most commonly in young, tall, and smoker men without underlying lung disease. Trends for PSP treatment tend toward more invasive procedures. Thoracotomy with pleurectomy and bullectomy is definitive treatment of PSP which significantly reduces recurrence probability. This procedure has been reported to cause high rate of morbidity and mortality. Thus video-assisted thoracoscopic surgery (VATS) has become the preferred method for treatment of PSP with recurrence rate of 5-10%. For persistent or recurrent cases, mechanical or chemical pleurodesis have been suggested. Based on guidelines patients with large size of lesions in CT or with unstable condition should undergo surgical procedure for recurrence prevention but Patients with small lesion size and stable condition can be only observed. Conservative management of PSP is safe and effective, but as mentioned this method has high recurrence rate. On the other hand fear of recurrence can negatively affect patients' quality of life, so that some patients prefer surgical intervention to observation management. Also some studies recommend invasive treatments because of cost effectiveness of this methods. As mentioned above, chemical pleurodesis is a usual method for treatment in patients with persistent or recurrent spontaneous pneumothorax. This method has been done using variety of chemical agents including tetracycline, minocycline, blood, and talc to irritate pleura. According to different studies tetracycline has the highest efficacy between irritant agents. In current study, the investigators have aimed to assess tetracycline chemical pleurodesis through tube thoracostomy in prevention of spontaneous pneumothorax in symptom free patients with normal CT-scan following first episode of PSP.

The study aims to evaluate the association between spontaneous pneumothorax onset and weather parameters.

Transthoracic lung biopsy (TLB) provides a histological diagnosis of nodule or lung mass. Pneumothorax is the main complication of TLB with an average of 20%. Many risk factors, whether clinical, computed tomography or related to TLB, are described in the literature. The British Thoracic Society recommends monitoring for 2 hours after the procedure with a possible discharge if the chest X-ray is normal. There is no French or European recommendation for monitoring the occurrence of pneumothorax after TLB. In the university center of Besançon, France, a minimum supervision of 4 hours is recommended and approximately one in two patients is hospitalized until the following day to reach this minimum time of 4 hours. The objective of the SPOT study is to perform a predictive score of pneumothorax from a retrospective cohort of patients for whom a transthoracic lung biopsy was performed and to validate this score on a prospective cohort. The expected goal is to select patients who can benefit from outpatient care by shortening the post-procedure surveillance period and to monitor more long-term only high-risk patients.
Currently chest X-ray (CXR) is the modality used to assess for pneumothorax after transthoracic lung biopsy at the Ottawa Hospital. Recently bedside Ultrasound (US) has become a useful rapid imaging modality to assess chest for pneumothorax in emergency rooms with reported sensitivity, specificity and diagnostic accuracy were 88%, 97% and 97%, respectively (ref. 2). Our team will be comparing the diagnostic accuracy of US to CXR in diagnoses of pneumothorax post transthoracic lung biopsy. The purpose of the study is to compare the diagnostic accuracy of US to CXR post-biopsy to confirm the presence of a pneumothorax.
