Filter by:The goal of this multicenter, double-blind, randomized controlled clinical trial is to compare the effect of intravenous lidocaine infusion on postoperative pulmonary complications in patients undergoing minimally invasive esophagectomy. The main question it aims to answer are whether intravenous lidocaine reduce postoperative pulmonary complications in patients undergoing minimally invasive esophagectomy. Participants will be given intravenous lidocaine infusion in lidocaine group or placebo in control group.
The aim of this study is to evaluate the effectiveness of intraoperative individualized positive end-expiratory pressure (PEEPIND) titration, compared to fixed positive end-expiratory pressure of 5 cmH2O, on oxygenation, hemodynamic variables, and early postoperative complications in obese patients undergoing laparoscopic bariatric surgery.
The current trend in most cardiac surgeries was to use rocuronium as it provides faster recovery in train-of-four ratio compared to other aminosteroid non-depolarising neuromuscular blocker. However, as most cardiac centres' standard of care does not perform any neuromuscular monitoring nor antagonism of neuromuscular blockade effect, residual neuromuscular blockade could potentially be the key to delayed extubation. As such, Cis-atracurium's organ-independent Hofmann elimination could be in favour.
The aim of this study is to evaluate the role of nitric oxide on pulmonary vasculature and right ventricular function in postoperative cardiac surgery patients.
This prospective randomized comparative study, to assess post-operative lung atelectasis by comparing calculated lung score using ultrasound between pediatric patients intubated with LMA (laryngeal mask airway) under volume versus pressure controlled modes of ventilation.
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.
Laparoscopic surgeries require carbon-dioxide into the abdomen which may occasionally lead to atelectasis. The extent of this atelectasis is not well documented in peri-operative period although it has been extensively researched in critical care set up. In this study, it is aimed to observe the ultrasonographic condition of lungs in laparoscopic pediatric surgeries. The hypothesis was the Lung Ultrasound Scores would worsen in those surgeries by the end of the operation. Aged between 1-18 years pediatric patients who are scheduled for laparoscopic surgeries will be included in the study to observe the changes in the lung visuals throughout the operation. For that, after safe endotracheal intubation first ultrasonography will be performed for the first (T1) time, and the second ultrasonography will be performed once the surgery is finished and before extubation (T2). Lastly, the third evaluation will be performed after 30 minutes in post anesthesia care unit (T3). Lung Ultrasound Score (LUS) is calculated as follows: Both hemi-thoraxes are divided into 6 different zones, and depending on the number of B-lines, which happens due to aeration loss in lung tissue, every zone is scored. If there is no B-line, it is zero points. If the B-lines in the visual lower than 4, the area is scored as 1 point. The areas with B-lines more than 3 is scored as 2 points. Furthermore, if there is any disruption on the pleural face, then the area is scored as 3 points. Accordingly, the worst case scenario refers 36 points, meaning the less the points the better the lung aeration. Primary outcome is defined as T2 LUS which will show the actual condition of at the end of the surgery. For that, T1 scores and T2 scores will be compared. The secondary outcomes include T3 LUS, (T3-T1)LUS, intraoperative hemodynamics, length of stay in Post Anesthesia Care Unite, postoperative aldrete scores for discharging to ward, and intraoperative ventilation variables.
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
1. Oxygenation index and bedside ultrasound would be used to evaluate the therapeutic effect of novel recruitment maneuver therapy in the patients with pulmonary atelectasis after cardiac surgery. 2. To establish a new therapy strategy for pulmonary atelectasis after cardiac surgery and to evaluate its effectiveness and safety for the cardiac patients complicated with postoperative pulmonary atelectasis.
