Filter by:Background - Assessment of the percentage of lung collapse is crucial in the therapeutic decision-making of pneumothorax. - The methods normally used to this purpose are radiological. Computerized tomography scan (CT) is highly accurate because it allows the exact evaluation of the volume of the air layer. However, in clinical practice assessment of the volume of pneumothorax mainly relies on the measurement of the inter-pleural distance at conventional chest radiography (CXR). This latter method is inaccurate. - Lung ultrasound is a new method highly accurate in the first diagnosis of pneumothorax, with a sensitivity superior to CXR and similar to CT in case of traumatic pneumothorax. - The scientific community is actually debating about the usefulness of lung ultrasound in the quantification of pneumothorax []. Lung ultrasound can assess the superficial extension of the pneumothorax, but cannot evaluate its volume. Aim - Main purpose of the study is to compare measurement of the superficial extension of pneumothorax on the chest wall obtained by lung ultrasound, to the evaluation of the air volume performed by CT in patients with pneumothorax. - The main hypothesis of the study is that the cut-off between small (<11% of lung collapse) and large (>11% of lung collapse) pneumothorax can be identified by a lung ultrasound evaluation of the superficial extension of pneumothorax. - Second purpose of the study is to compare the accuracies of lung ultrasound and CXR in predicting the volume of pneumothorax assessed by CT. - Secondary hypothesis is that lung ultrasound demonstrates greater accuracy in the prediction of volume of pneumothorax and percentage of lung collapse. Methods - Patients with a diagnosis of pneumothorax confirmed at CT are prospectively enrolled and submitted to lung ultrasound within 20 min from the CT study. - Different locations of the sonographic "lung point" on the chest wall (i.e. the point on the chest wall where the sonographic pattern of the normally aerated lung alternates with the pathologic sonographic pattern of pneumothorax) are compared with different volumes of pneumothorax measured by CT.
Discharging patients home with air leak and chest tube to portable drainage device after thoracic resection is cost effective and safe without compromising patients outcome or satisfaction. Despite good outcomes this practice is not done universally by thoracic surgeons.
A small 14-French(F) pigtail catheter (PC) has been shown to work equally well with traditional 32-40F chest tube (CT), especially in traumatic pneumothorax. There are no clinical data on tube-site pain. The investigators hypothesize that PC tube site pain is less than CT.
The purpose of this study is to investigate whether if KatGuide (a new developed medical device) improves the placing of a large bore chest tube in the pleural cavity compared to the conventional method.
The purpose of this study is to: 1. Evaluate the validity of using abnormal characteristics of the pneumothorax line, as evaluated from chest X-ray film, as the operative indications for video-assisted thoracic surgery (VATS) on primary spontaneous pneumothorax (PSP). 2. Through a randomized double blind controlled trial on patients whose PSP was caused by lung bullae, evaluate the effectiveness of pleurodesis in terms of the rate of recurrence of PSP and the trauma of the operation on patients. 3. Based on the findings, establish selection standards for the timing of surgery to treat PSP by VATS and establish technical specifications for performing operations on different types of lung bullae. The goal is to improve the diagnosis and treatment of PSP so as to reduce the recurrence rate of pneumothorax, reduce the trauma of operation, shorten hospital stays and postoperative recovery time, and provide better services for returning to everyday life and improving the quality of life for patients.
A retrospective study to demonstrate the optimal depth of right side bronchial blocker for complete right lung separation. Data were collected from all patients who completed right side VATS with right side BB from Jan 2010 through Nov 2010.
Spontaneous breathing supported by nasal continuous positive airway pressure (nCPAP) is thought to have some advantages compared with mechanical ventilation in premature infants. In addition, early surfactant administration has been shown to be superior to delayed use. The aim of this pilot study was to describe the feasibility of TAKE CARE (early administration of surfactant in spontaneous breathing) procedure and compare its short-term and long-term results with InSurE procedure.
The investigators conducted a prospective randomized study to compare axillary minithoracotomy versus a modified two-port thoracoscopic technique for surgical pleurodesis in patients with recurrent spontaneous pneumothorax operated in a single institution. The main objective of the study was to investigate possible differences regarding short- and long-term clinical outcome between the two different techniques.
Primary spontaneous pneumothorax most commonly occurs in young, tall, lean males. The estimated recurrence rate is 23-50% after the first episode and increases to 60% after the second pneumothorax. The pathogenesis of this benign disease remains unclear. Generally, rupture of the emphysematous change or blebs in the apex of the lung is considered as the cause of pneumothorax. The main purpose of this study is to investigate the molecular pathogenesis of blebs formation or emphysematous change of the lung in these young, healthy patients.
The purpose of this study is to examine the efficacy of prophylactic antibiotics in patients with chest tubes for management of thoracic injuries in the reduction of the incidence of empyema as compared to placebo.
