Filter by:This study will be conducted to determine the advantages and limitations of sonography compared with chest radiography, in the detection of post procedure iatrogenic pneumothorax in patients underwent to Pectus Excavatum (PE) with Nuss repair.
During general anesthesia, functional residual capacity (FRC) is reduced. If the FRC is lower than the minimum volume required to maintain the opening of the airways, there is a derecruitment of the lung parenchyma, leading to the phenomenon of expiratory flow limitation (EFL). The Driving Pressure (DP) is the difference between the plateau pressure (Pplateau) and the Positive End-Expiratory Pressure (PEEP), and estimates the lung strain. The incidence of EFL and the importance of DP are not known in adult cardiac surgery, so it's necessary a study to assess both. The primary end-point of the study is to evaluate the correlation of DP and EFL with PPCs in adult cardiac surgery. The secondary end-point of the study is to evaluate: the mechanical ventilation time, the length of ICU and hospital stay, the rehospitalization and mortality. It will be a prospective, observational, non-pharmacological study. It will enroll 200 patients undergoing elective adult cardiac surgery.
Background: Insertion of a central venous catheter (CVC) could lead to a variety of complications. To detect those complications, Chest X-ray (CXR) is still the reference standard. However, there are major limitations in performing CXR's in the critical care setting. Aim/objectives: The objective of this study is to compare the use of bedside ultrasound (US) to conventional CXR in visualization of accuracy and safety of the CVC placement. The aim is to eventually replace X-ray with bedside ultrasound as gold standard for the confirmation of CVC-placement in critically ill patients, thereby reducing radiation exposure and unnecessary delay before CVC use. Methods: The bedside US will be performed by the student or attending physician, who is blinded for CXR findings. After US examination, the attending physician (or student) will fill in a structured form, based on an established protocol. CXR will be performed before or after US examination and assessed by a radiologist. The radiologist will be blinded for the findings of the bedside ultrasound to prevent any biases. Final diagnosis will be determined after examination of the complete medical chart.
This clinical trial is conducted within the research project 'Computerized Lung Sound Analysis'. The research goal is the development of a system enabling the automatic classification of lung sounds, which will result in a decision support system for physicians. The objective of this trial is to create a small lung sound corpus, enabling the development of a prototype of the described system. Therefore, investigators record lung sounds with several lung sound transducers distributed on the posterior chest of human test subjects.
Lung isolation technique is useful for lung or heart surgeries for better visualization. Double lumen endobronchial tube and bronchial blocker are available for lung isolation. Adding disconnection technique before lung isolation is helpful to accelerate the lung deflation. However, the utility of disconnection technique has never been evaluated in comparison of double lumen tube and bronchial blocker. Therefore, the utility of disconnection technique in two different lung isolation technique, double lumen tube and bronchial blocker will be evaluated
Patients with chest trauma undergo ultrasound to detect a collapsed lung. Two techniques have been described. A single view for each hemi-thorax, and multiple views for each hemithorax. The investigators are comparing these two techniques in a randomized prospective trial.
The objective of this multi-center, non-randomized, prospective pilot study is to examine the rate of successful primary spontaneous pneumothorax (PSP) resolution using the simple aspiration technique. In this study, eligible subjects diagnosed with PSP at eleven participating large children's hospitals (members of the Midwest Pediatric Surgical Clinical Research Consortium) will be enrolled and offered a choice of management with either the simple aspiration protocol or management according to their surgeon's preference, which may include simple aspiration, chest tube placement, or rarely, an operation.
Traditional closed thoracostomy exhibit certain shortcomings. Blind dissection is a lengthy process that is difficult for unskilled physicians, whereas the use of a traditional trocar is relatively likely to damage internal organs. In this study, investigators developed a new trocar and examined its usefulness.
Monocentric observational study of needle exsufflation for pneumothorax in the ICU.
Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo abdominal and limb operations. In a pilot study arm electrical impedance tomography is tested in patients receiving osteosynthesis of serial rib fractures.
