Filter by:The primary objective of this prospective observational physiological study is to evaluate the variation in regional distribution of intrapulmonary volume in the dependent and non-dependent lung regions in patients undergoing neurosurgical intervention between supine and Park-Bench position.
In thoracic surgery, the incidence of postoperative pulmonary complications is higher than for other surgeries. Indeed, thoracic surgery has the specificity of being carried out with single-lung ventilation and is thus a source of intraoperative atelectasis which persists postoperatively and gives rise to pulmonary complications, particularly infectious ones. During one-lung ventilation, mediastinal and abdominal compression on the ventilated lung leads to a drop in functional residual capacity (FRC) which will in turn lead to collapse of the small airways leading to the formation of atelectasis. Strategies exist to limit the appearance of atelectasis. One of the intraoperative strategies is alveolar recruitment. Alveolar recruitment is a dynamic process that can be defined by a transient increase in transpulmonary pressure beyond the critical opening pressure. Physiologically, alveolar recruitment corresponds to the re-aeration of poorly or non-aerated lung areas. In single-lung ventilation, intraoperative alveolar recruitment maneuvers are not performed systematically to prevent the formation of atelectasis. The General Electric Carescape R860 ventilator allows intraoperative monitoring of end-expiratory closing lung volume (EFVP), which corresponds to the CRF associated with positive expiratory pressure (PEEP). This spirometry incorporated in the ventilator continuously monitors the intraoperative variation of VPFE, thus making it possible to detect any significant decrease which would favor the formation of intraoperative atelectasis. Early detection of VPFE can therefore allow the anesthetist-resuscitator to initiate intraoperative alveolar recruitment maneuvers adapted to the patient. Alveolar recruitment maneuvers are then personalized and based on precise monitoring of the evolution of the VPFE. The effectiveness of recruitment maneuvers can be evaluated and quantified (with the Lung Ultrasound Score (LUS)) postoperatively using pleuropulmonary ultrasound. Thus, early ultrasound detection, from the post-interventional monitoring room (SSPI), would make it possible to undertake rapid therapeutic maneuvers to combat the atelectasis observed. A patient could benefit, for example, from prophylactic NIV from the recovery room, from a stricter postural program in a seated position, or from an earlier and/or more intensive respiratory rehabilitation program with the physiotherapy team.
Transfusion-related acute lung injury (TRALI) is a severe complication of blood transfusions. After a transfusion, TRALI develops in 0.08-15% of cases. The incidence of TRALI is 50-100 times higher in critically ill patients compared to the general hospital population. No biomarkers are yet known to detect TRALI. This study will compare blood samples of TRALI patients with blood samples of intensive care patients in order to find possible biomarkers for TRALI.
In this study, changes in new oxygenation indices investigated by Asar et al. will be compared with conventional oxygenation and saturation indices in patients undergoing robot-assisted laparoscopic surgery due to pneumoperitoneum and Trendelenburg position.
The goal of this clinical trial is to investigate the effect of perioperative administration of vitamin C on postoperative pulmonary complications, with the aim of providing a safe and effective medication regimen for the prevention and treatment of postoperative pulmonary complications in patients undergoing surgery for craniocerebral tumors. The main questions it aims to answer are: 1. To determine whether vitamin C can reduce pulmonary complications after surgery for intracranial tumors. 2. Does intraoperative vitamin C improve the prognosis of surgical patients Researchers will compare vitamin C to a placebo (saline) to see if vitamin C is effective for postoperative lung complications in patients undergoing surgery for cranial tumors. 1. Participants will be intravenously pumped with vitamin C for two hours after induction of anesthesia. 2. Participants will have intraoperative plasma sampling and recording of ventilator parameters, monitor parameters and perioperative data. 3. Participants will be followed up until discharge from the hospital to record symptoms and adverse events, and will be called at six months to check on their prognosis.
The goal of this study is to conduct a prospective, double-blind, randomized placebo-controlled clinical trial to investigate the safety and efficacy of mesenchymal stem cells treatment for Lung injury caused by major infectious diseases.
We aimed to compare different formulations of mechanical power using geometric methods at varying inspiratory rise and pause times.
This study investigates the relationship between intraoperative mechanical power and postoperative pulmonary complications in patients undergoing major abdominal surgery. We record mechanical ventilation parameters and surgical characteristics, assessing the incidence of pulmonary complications within 24 hours postoperatively
1. We collect lung tissues from patients with different ages and confirm that KLK8 expression is positively correlated with age. 2. We collect peripheral blood from patients with different ages and duration of mechanical ventilation to explore the correlation between the degree of endothelial/epithelial damage, age and duration of mechanical ventilation.
The Continuous Tracheal Gas Insufflation (CTGI) is a ventilation option of conventional ventilation to reduce or even cancel dead space due to respiratory prostheses. This objective is particularly interesting in the smallest preterm infants in which the volume of anatomical dead space due to prostheses is little different from the tidal volume. The principle of this option is to continuously blow an additional flow of 0.2 L/min at tip of endotracheal tube to purge expired CO2 trapped in the prostheses to have a CO2-free volume of gas available for subsequent insufflation.
