Filter by:Preventing hypoxemia is one of the major goal of studies for bronchoscopic sedation. Dexmedetomidine is a sedative agents via α2 adrenergic agonist, with little respiratory suppression. In the preset study, we evaluate the safety and feasibility of the Dexmedetomidine in the specific bronchoscopic procedure, endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration.
Flexible bronchoscopy is a commonly performed procedure and is usually performed transnasally. The optimal topical anesthesia regimen for bronchoscopy is investigational. Topical Vasoconstrictors like xylometazoline produce decongestion of nasal mucosa and may make insertion of bronchoscope easier. The addition of topical vasoconstrictor to lignocaine may have advantage in terms of patient comfort and for reducing local complications. Although evaluated in the settings of nasal endoscopy and nasotracheal intubation, randomized trials on the role of topical vasoconstrictors during flexible bronchoscopy are not available. The aim of this randomized trial is to study the effect of topical nasal xylometazoline administration during flexible bronchoscopy.
The aim of this study is to evaluate the usefulness of the new Ambu® aScope ™ 4 bronchoscope, in the usual practice of low complexity diagnostic bronchoscopy managed by bronchoscopists who meet the minimum training requirements (having performed 100 supervised procedures [ 10]) and maintenance of competition (with more than 25 bronchoscopies per year [10]).
This study is designed as a prospective observational, non-controlled, non-interventional study. The aim of this study is to obtain a broad user perspective of the aScope™ 4 Broncho, focusing on the device functionalities within regular clinical practice and therapeutic use of flexible bronchoscopes in the OR and ICU. The study will include a minimum of 100 adult patients admitted to the operating room (OR) or Intensive Care Unit (ICU) undergoing at least one bronchoscopy procedure. The inclusion will stop when 100 fully evaluable patients or a maximum of 150 patients have been enrolled. The involved sites will include patients during a five months' period, from September 2017 to January 2018.
The purpose of this study is to investigate whether diagnostic bronchoscopy can be safely and potentially more effectively performed without the use of tracheal intubation or a supraglottic airway, under completely unobstructed surgical conditions afforded by THRIVE: Transnasal Humidified Rapid- Insufflation Ventilatory Exchange. THRIVE provides patient's gas exchange through rapid insufflation of high-flow oxygen via specialized nasal cannula.
A prospective, double-blind, randomized, placebo and active controlled, multi-center, parallel group study comparing remimazolam to placebo, with an additional open label arm for midazolam, in patients undergoing a bronchoscopy.
Retrospective analysis of data concerning anastomotic airway complications after lung transplantation.
Feasibility of using an extra bronchoscopic channel for supplementation of oxygen will be studied by comparing O2-supplementation by nasal cannulae versus O2-supplementation through aspiration channel of the bronchoscope.
Bronchoalveolar lavage (BAL) is a common technique among pulmonologists. Its goal is to collect cells from alveolar units. This is done by wedging a flexible bronchoscope in a bronchus, instilling saline, and removing the saline via suction. Two techniques are currently used for suctioning: syringe based and channel suction. The investigators concern is that channel suction creates too much force and there is collapsing of the airways which results in decreased fluid removal as well as cell sampling. The investigators propose that syringe based suctioning will not only return more of the instilled fluid but also more cells from the alveoli.
The purpose of this study is to find the best sedation necessary for patients undergoing bronchoscopy. Patients are randomized to three different regimes of sedation during bronchoscopy were studied: 1. - Group standard/control: local anesthesia only(C) 2. - Group alfentanil + local anesthesia(A) 3. - Group dexmedetomidine + local anesthesia(D) The primary endpoint is the bronchoscopy score. Secondary endpoints are: Level of sedation and tolerance bronchoscopy examination. Measured parameters on the safety of examination are: the lowest saturation, needs to supplemental oxygen, amnesia , choking sensation or chest pain and if the patient is ready or not to undertake bronchoscopy second time in his life if necessary. Endtidal CO2, Respiratory rate, Blood pressure, Heart rate, level of oxygen are collected every 5 minutes before, during and after the bronchoscopy.
