Filter by:Perioperative respiratory complications are a major source of morbidity and mortality. Postoperative atelectasis plays a central role in their development. Protective "open lung" mechanical ventilation aims to minimize the occurrence of atelectasis during the perioperative period. Randomized controlled studies have been performed comparing various "open lung" ventilation protocols, but these studies report varying and conflicting effects. The interpretation of these studies is complicated by the absence of imagery supporting the pulmonary impact associated with the use of different ventilation strategies. Imaging studies suggest that the gain in pulmonary gas content in "open lung" ventilation regimens disappears within minutes after the extubation. Thus, the potential benefits of open-lung ventilation appear to be lost if, at the time of extubation, no measures are used to keep the lungs well aerated. Recent expert recommendations on good mechanical ventilation practices in the operating room conclude that there is actually no quality study on extubation. Extubation is a very common practice for anesthesiologists as part of their daily clinical practice. It is therefore imperative to generate evidence on good clinical practice during anesthetic emergence in order to potentially identify an effective extubation strategy to reduce postoperative pulmonary complications.
This study will use lung ultrasounds (LUS) to evaluate the incidence and severity of intraoperative atelectasis in anesthetized children undergoing minor surgery using a laryngeal mask airway. The children will be randomly assigned to be left in spontaneous ventilation with a Positive End Expiratory Pressure (PEEP) of 5cmH2O or to be ventilated with a pressure support mode.
To investigate the hypothesis that an alveolar recruitment maneuver after the release of pneumoperitoneum would restore the lung compliance to the baseline values after a laparoscopic gynaecologic surgery.
The goal of this observational study is to learn more about the effect of obstetric epidural anesthesia on regional lung ventilation in healthy parturient women. The main question it aims to answer is whether the initiation or epidural analgesia improves or not regional lung ventilation in healthy women at term during labor. Participants will be subject to measurements of pulmonary impedance by electric impedance tomography before and after the start of epidural analgesia. No change will be applied to clinical care as a result of this measurement.
This study will investigate the distribution of gas during mechanical ventilation in patients undergoing robot assisted laparoscopic prostatectomy. The gas distribution of ventilation are monitored and data extracted using electric impedance tomography in different respiratory rates.
Single Use Flexible bronchoscopes have gained popularity in recent years and are becoming technologically more advanced. They are widely accepted and used in everyday practice for simple procedures. The aim of this study is to evaluate single use flexible bronchoscopes in more advanced settings, such as interventional pulmonary procedures.
This study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The Lunit INSIGHT CXR is a validation study that aims to assess the utility of an Artificial Intelligence-based (AI) chest X-ray (CXR) interpretation tool in assisting the diagnostic accuracy, speed, and confidence of a varied group of healthcare professionals. The study will be conducted using 500 retrospectively collected inpatient and emergency department CXRs from two United Kingdom (UK) hospital trusts. Two fellowship trained thoracic radiologists will independently review all studies to establish the ground truth reference standard. The Lunit INSIGHT CXR tool will be used to analyze each CXR, and its performance will be measured against the expert readers. The study will evaluate the utility of the algorithm in improving reader accuracy and confidence as measured by sensitivity, specificity, positive predictive value, and negative predictive value. The study will measure the performance of the algorithm against ten abnormal findings, including pulmonary nodules/mass, consolidation, pneumothorax, atelectasis, calcification, cardiomegaly, fibrosis, mediastinal widening, pleural effusion, and pneumoperitoneum. The study will involve readers from various clinical professional groups with and without the assistance of Lunit INSIGHT CXR. The study will provide evidence on the impact of AI algorithms in assisting healthcare professionals such as emergency medicine and general medicine physicians who regularly review images in their daily practice.
Children have a highly compliant chest wall and atelectasis formation occurs often during pediatric anesthesia. Inhalation induction is commonly performed in pediatric anesthesia but it is still unclear if this can have an effect on the development of atelectasis. Aim of this study is to investigate the impact of inhalation versus intravenous induction on atelectasis formation during anesthesia induction in children. Atelectasis will be evaluated with lung ultrasound before induction and right after induction.
To study the effect of high flow nasal cannula in comparisons with nasoprong used intraoperatively in patients oxygenation status
This study was divided into two parts, taking elderly patients undergoing general anesthesia surgery as the research subjects, through factorial design: 1. It was verified that in elderly patients undergoing general anesthesia surgery, innovative lung-protective ventilation strategies can reduce the occurrence of atelectasis and reduce the incidence of ventilator-related lung injury and postoperative pulmonary complications more than traditional lung-protective ventilation strategies; 2. On the basis of part one study proving that innovative lung-protective ventilation strategies can reduce the incidence of postoperative atelectasis and other complications in elderly patients undergoing general anesthesia surgery compared with traditional lung-protective ventilation strategies, further comparisons were made between the two factors of "positive pressure extubation" and "improved early postoperative respiratory training" in the innovative lung protective ventilation strategy, and whether there was an interaction between the two.
