Filter by:The purpose of this randomized controlled study is to evaluate the extent to which injection of a small amount of fluid in the pleural cavity at the biopsy site may reduce the risk of pneumothoraces, in addition to patient positioning to allow biopsy in gravity-dependent areas of the lung.
During cardiopulmonary bypass (CPB), oxygenation of the patient on the pump can be left completely under pump control, or the lungs can be ventilated with low tidal volume to reduce atelectasis. In recent years, the concept of mechanical power has been used to determine the extent of ventilator-related lung damage. This concept of mechanical power, by which the energy transferred by the ventilator to the lungs can be calculated, will be measured at certain intervals in CPB surgery patients on the pump and compared between the two groups. The investigators aimed to investigate the effect of two different ventilation methods on mechanical power and its relationship with postoperative pulmonary complications.
Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life. Available drug treatments have moderate efficacy whereas surgical lung volume reduction can improve exercise capacity when offered to a very selected population but at the cost of significant morbidity and mortality. Endoscopic Lung Volume reduction with ZEPHYR® valves improves respiratory function at rest, exercise tolerance and quality of life in patients with little or no interlobar collateral ventilation. If this technique has therefore proven its effectiveness, it is not devoid of complications and is notably responsible for pneumothorax in 27% of cases. The management of this complication is clearly codified, ranging from patient monitoring to the removal of one or more valves. It is therefore a subject of major concern for multiple reasons: high incidence, lengthening of hospital stay, increase in the overall cost of care, potential loss of benefit for the patient in the event of permanent withdrawal. valves and above all a potentially fatal event. A new strategy for implanting ZEPHYR® valves in two stages has been developed in Limoges University Hospital. This innovative algorithm has been evaluated in several non-comparative single or multicenter studies. In those studies, pneumothorax' rate secondary to lung volume reduction with endobronchial valves is rated between 4.5 and 12%. The efficacy of the treatment appears to be comparable with the data found in the trials evaluating in which the entire lobe was treated in one procedure. Moreover, despite two procedures, there does not seem to be any increased risk of occurrence of other complications. Finally, the systematic scheduling of a thoracic computed tomography between the two procedures showed that 26.6% of patients presented a reduction in volume greater than 350mL despite incomplete treatment. These data seem promising but no direct comparison with standard one-step treatment has ever been conducted so far.
With the continuous strengthening of the concept of rapid rehabilitation, great progress has been made in minimally invasive thoracic surgery, and thoracoscopic surgery has developed rapidly. Double-lumen endotracheal(DLT) intubation is still the most reliable way of intubation in lung surgery. However, hypoxemia faced during double-lumen intubation still threatens the perioperative safety of thoracic surgery patients. In recent years, high-flow nasal oxygenation (HFNO) has great potential in the field of anesthesia, especially playing a new and important role in the prevention and treatment of short-term hypoxia and life-threatening airway emergencies. However, the use of HFNO in pulmonary surgery patients with poor pulmonary function lacks evidence-based basis, and there are few reliable clinical data. This study adopted a prospective, randomized, controlled, single-blind design. A total of 100 patients aged 18-60 years who underwent elective thoracoscopy-assisted pulmonary surgery were included and randomly divided into the experimental group: HFNO was used in the process of double-lumen intubation asphyxia; the control group: according to the traditional intubation process, No oxygen therapy equipment was used during intubation asphyxiation. The lowest blood oxygen saturation during intubation, the incidence of hypoxemia during intubation, perioperative complications, and postoperative hospital stay were compared between the two groups. This study explores the advantages of HFNO in complex endotracheal intubation, assuming that HFNO can improve the oxygen saturation of double-lumen intubation; optimize the intubation method of DLT, and tap its new potential to prevent and manage emergency airway crisis.
Assessment and evaluation of Pigtail application in drainage of pneumothorax and haemothorax.
All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.
This study aims to evaluate the efficacy of single dose analgesia in combination with local anesthesia to control pain during Trans Ultrasound guided procedures. It also aims to assess the effect of its use on procedure performance time and rate of complications occurrence compared to local anesthesia alone.
To compare between small sized tube thoracostomy and large sized tube thoracostomy regarding the need for another chest tube for the fear of obstruction (in hemomothorax) or ineffective drainage (in hemothorax, pneumothorax or hemo-pneumothorax) ,pain score or repositioning and need for thoracotomy.
There was no evidence that the number of chest tube do effect to the recurrence of pneumothorax, which placed after thoracoscopic wedge resection together with mechanical pleurodesis.This study evaluates the efficacy of single chest tube versus multiple tubes drainage in spontaneous pneumothorax after VATS bullectomy and pleurodesis. After routine procedure the participants will randomized to either placed single chest tube or multiple chest tubes
According to the problems of traditional closed thoracic drainage in clinical work, this study aims to further improve and improve the new closed thoracic drainage system by changing the material of drainage tube, increasing the regulating valve of external fixator and increasing the gas flow monitoring kit for special patients, so as to expand its clinical application scope and formulate its operation. Standardize. At the same time, through a randomized controlled study, the simplicity, effectiveness and safety of the new minimally invasive thoracic closed drainage system developed by the research group were deeply studied.
