NCT07267897
This prospective, randomized clinical trial aims to evaluate the effect of preoperative nebulized lidocaine and nebulized 3% hypertonic sodium chloride (NaCl) on the incidence of postoperative respiratory complications in pediatric patients undergoing adenoidectomy and/or adenotonsillectomy. Lidocaine, a versatile sodium channel blocker, has shown antitussive, bronchodilatory, and anti-inflammatory benefits when nebulized, and has been safely used in children for respiratory procedures. Hypertonic 3% NaCl is known to improve mucociliary clearance, reduce airway edema, and enhance secretion mobilization, particularly in pediatric respiratory conditions. Both agents have demonstrated individual safety and efficacy in respiratory management, yet their preoperative nebulized use for preventing postoperative respiratory adverse events (PRAEs) in pediatric airway surgery has not been previously studied. This trial seeks to determine whether preoperative nebulization with these agents can reduce postoperative respiratory complications, improve recovery, and enhance perioperative safety in this high-risk population.
NCT06234774
This secondary analysis aims to identify factors associated with the development of postoperative pulmonary complications (PPCs) in patients undergoing abdominal surgery, pooling and analyzing the data of two worldwide prospective studies, the 'Epidemiology, Practice of Ventilation and Outcome for Patients at Increased Risk of Postoperative Pulmonary Complications' (LAS VEGAS, NCT01601223) and the 'Assessment of Ventilatory management during general AnesThesia for Robotic surgery and its effects on postoperative pulmonary complications' (AVATaR, NCT02989415). The primary aim is to compare the incidence of PPCs between patients undergoing non-robotic surgery versus patients undergoing robot-assisted surgery. One secondary aim is to determine which factors are associated with the occurrence of PPCs. The investigators hypothesize that differences in the occurrence of PPCs between the two surgery groups are more driven by differences in duration of anesthesia than by the intensity of ventilation.
NCT03356496
Postoperative pulmonary complications (PPCs) are a source of much morbidity and mortality. Rates of PPCs exceed 30% in patients with multiple risk factors. Several studies have demonstrated reduced PPCs in patients who underwent preoperative inspiratory muscle training. These studies largely focused on cardiothoracic surgery and required the use of respiratory therapists. The investigators hypothesize that preoperative, self-administered respiratory therapy would reduce PPCs in patients with risk factors for PPCs undergoing any non-cardiothoracic surgery. This study is a randomized, controlled trial comparing preoperative use of an incentive spirometry device with usual care in patients undergoing non-emergent, non-cardiothoracic surgical procedures under general anesthesia.
NCT05224895
The aim of this study is to compare the changes in upper airway edema with the preoperative and postoperative ultrasonographic measurements of patients who undergo pobotic prostatectomy in the trendelenburg position. The secondary aim is to investigate the correlation between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
NCT04723433
The purpose of this randomized, controlled feasibility investigation is to characterize pharmacologically induced ventilatory depression after anesthesia and examine how is affected by the amount of supplemental oxygen patients are receiving in the immediate postoperative period.
NCT04860648
Postoperative pulmonary complications (PPCs) occur in many patients, especially those with high risks, and are associated with increased hospital length of stay, morbidity and costs of care. According to European Perioperative Clinical Outcome definitions, major pulmonary complications include atelectasis, respiratory infection, pleural effusion, and pneumothorax. Because identifying patients at high risk for PPCs may allow earlier treatment, predictive scores ( the Assess Respiratory Risk in Surgical Patients in Catalonia score \[ARISCAT\]) have been developed.Lung ultrasound (LUS) is more accurate than chest X-ray in diagnosing pulmonary complications, and lung ultrasound performed in the postanesthesia care unit may identify patients at higher risk for pulmonary complications. So we aimed to study if lung ultrasound can guide the prevention of PPCs in moderate to high risk patients.
NCT03585400
Neuromuscular blocking agents' (NMBA) use during surgery is associated with postoperative respiratory complications and increased risk of readmission to the hospital following ambulatory surgery. Residual neuromuscular block (rNMB) after surgery is difficult to identify. We have recently developed the REsidual neuromuscular block Prediction Score (REPS), that predicts the risk for postoperative rNMB. Our primary objective is now to assess the predictive ability of the REPS for respiratory complications within seven days following general anaesthesia. The secondary objective is to compare the predictive values of REPS and train-of-four (TOF)-ratio below 0.90 for respiratory complications.
NCT01441791
The purpose of this international, multicentre, double-blinded randomized controlled trial is to determine if the "open lung approach" providing recruitment maneuvers and PEEP(Positive End Expiratory Pressure) during general anesthesia reduces atelectasis formation and improves respiratory function in the immediate post-operative period after major abdominal surgery. Participating centres throughout the world will include a total of 900 adult patients undergoing general anesthesia for open abdominal surgery with high or intermediate risk for post-operative pulmonary complications. Patients are randomized and intra-operatively ventilated with either a lung protective strategy (PEEP at 12 cmH2O with recruitment maneuvers) or a conventional strategy (PEEP at maximum 2 cmH2O without recruitment maneuvers). Patients will be assessed on the first 5 post-operative days, on day of discharge and on day 90 post-operative. Primary endpoint is any post-operative pulmonary complication (see below). Secondary endpoints are post-operative extra-pulmonary complications, intra-operative mechanical ventilation related complications, unscheduled ICU (Intensive Care Unit) (re-) admission, and length of hospital stay.
