Filter by:After respiratory weaning, decannulation is sought. To do this, the tracheal cannula is first unblocked, so that patients no longer breathe in and out through the cannula, but (at least partially) "passing" the cannula by the natural route. In the presence of tracheal stenosis there is increased breathing effort, possibly restlessness and stridor. This constellation of symptoms suggests the suspicion of tracheal stenosis, so in the next step a tracheoscopy is performed to confirm or exclude tracheal stenosis. In case of symptomatic tracheal stenosis and at least 30-50% stenosis of the trachea (clinical symptoms can be expected from a 30-50% stenosis) then appropriate therapy (here: cryotherapy, other techniques only in exceptional cases) is planned. The goal is to be able to remove the tracheal cannula (long term) after successful therapy, so that patients do not have to be permanently provided with a tracheal cannula. There is no definitive/evidence-based standard therapy for the treatment of tracheal stenosis. Cryotherapy is a gentle therapy that has already been applied and described for the treatment of tracheal stenosis (see above). The examination is performed as part of an analgesic dose, as is routine for a bronchoscopy (in-house SOP). After treatment, a follow-up is planned for about 10 days later.
The study presents an alternative method of tracheal dilatation in pediatric patients with acquired tracheal stenosis. Dilatation is performed by the use of balloon catheter connected with manometer, that is bronchoscopic guided into trachea in the stenotic area, through the wide canal of supraglottic device i-Gel. Every dilatation cession consists of three consequent tracheal balloon dilatations of maximum 3 minutes duration each, followed by 10-15minutes interval of controlled ventilation. The balloon is inflated for 60 seconds to reach predefined pressure, and then deflated. This method is minimal traumatic for tracheal mucosa, and application of several dilatation procedures every 2-3months, in pediatric patients with acquired tracheal stenosis, may lead to a relative reopening of trachea and recession of clinical symptoms.For the right performance of the dilatation procedure, patients receive general anesthesia with cessation of spontaneous ventilation. During procedure, controlled ventilation-oxygenation is impossible, because the i-Gel canal is occupied by bronchoscope and balloon catheter, so patients will remain apneic for a short period of time. For pediatric patients is important to perform proper preoxygenation prior to procedure, and to maintain oxygenation as long as possible during procedure. This is achieved by application of apneic oxygenation, through a small catheter, connected to high flow oxygen. Participants are exposed during first dilation to no oxygenation, while during second and third dilatation to apneic oxygenation. Aim of the study is to investigate primarily whether application of apneic oxygenation, in pediatric patients during tracheal balloon dilatation, maintains regional cerebral oxygen saturation rSO2 in significant higher levels, compared with no application of oxygenation. rSO2 levels are a sensitive index of oxygenation efficacy of the brain, accordingly this refers to a safe procedure. Secondary issues are whether application of apneic oxygenation maintains pulse oximetry SpO2 and artierial oxygen partial pressure PaO2 in higher levels, and what are the effects on arterial carbon dioxide partial pressure PaCO2 and on haemodynamic parameters (heart rate, blood pressure), compared with no application of apneic oxygenation.
Multicenter randomized controlled trial comparing endoscopic laser resection vs dilatation in benign tracheal stenosis.
Define the actual incidence of tracheal stenosis in patients who underwent either prolonged intubation or tracheostomy and to compare incidence, clinical course and outcome between COVID-19 and non-COVID-19 patients.
The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on maintenance of oxygenation and removal of carbon dioxide during apnoeic period in pediatric patients undergoing general anesthesia with rigid bronchoscopy
The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on apnea in patients undergoing general anesthesia with rigid bronchoscopy compared with standard anesthesia methods.
In this study, we used the covered metallic segmented airway stent to treat malignant strictures involving carina and bronchi distal to carina and aimed to determine the feasibility, efficacy and safety of this technique.
The investigators propose a preliminary study performing exome sequencing on samples from patients and their biologically related family members with tracheal and esophageal birth defects (TED). The purpose of this study is to determine if patients diagnosed with TED and similar disorders carry distinct mutations that lead to predisposition. The investigators will use advanced, non-invasive magnetic resonance imaging (MRI) techniques to assess tracheal esophageal, lung, and cardiac morphology and function in Neonatal Intensive Care Unit (NICU) patients. MRI techniques is done exclusively if patient is clinically treated at primary study location and if patient has not yet had their initial esophageal repair.
Investigators aim to study the effectiveness and safety of inhaling hydrogen-oxygen which produced by a hydrogen generator with nebulizer to decreases inspiratory effort for the patients with tracheal stenosis.
