Filter by:The purpose of this study is to investigate the effect of using the McMurray Enhanced Airway (MEA) which is a flexible extended-length distal pharyngeal airway on improving oxygen delivery compared to standard nasal cannula.
The goal of this Prospective Trial of Paclitaxel-Coated Pulmonary Balloon for the Treatment of Benign Airway Obstruction (OXYGEN-1) is to evaluate clinical safety and potential efficacy of the Airiver Pulmonary DCB in the treatment of benign central airway stenosis.
Thermal ablation (use of treatment modalities that generate heat) has become a widely used tool for treatment of central airway obstruction (e.g. laser, electrocautery, radiofrequency, and argon plasma coagulation). However, this method carries with it an increased risk for airway fire - a surgical fire that occurs in a patient's airway and could also include a fire in the attached breathing circuit. To decrease the risk of airway fire during mechanical ventilation with an endotracheal tube, the concentration of inspired oxygen (FiO2) is set below 40% while waiting for end tidal oxygen concentration (EtO2) to fall below 40% prior to starting thermal ablation. There is no published literature describing O2 concentration within the airways (AiO2) during jet ventilation with rigid bronchoscopy. The co-investigators of this study have recently collected data on AiO2 during rigid bronchoscopy using manual low frequency jet ventilation/high frequency jet ventilation with a period of apnea. The intent of this study is to measure the time taken for the central airway oxygen concentration to drop from 90 to 40% when the "laser mode" is activated on the Monsoon jet ventilator. Ventilation is continued during "laser mode."
The objective of ILAN is to assess the safety, feasibility and bronchodilator efficacy of in-line bronchodilator nebulizer delivery with VMN via HFNC system in hypoxemic respiratory failure patients treated with bronchodilators and compare this method to standard-nebulization using a jet nebulizer with a facial mask. The investigators hypothesized that aerosol nebulization using HFNC/VMN represents safer and more convenient approach in hypoxemic respiratory failure patients in comparison to conventional therapy while providing similar bronchodilator efficacy.
Sedoanalgesia is applied to patients during gastrointestinal endoscopy. Sedoanalgesia may cause respiratory depression and hypoxia in patients. During these procedures, patients should be given oxygen support to reduce the incidence of hypoxia.This study aimed to compare the efficacy and procedural performance of two different airway devices (Wei Nasal Jet Tube vs Nasal Cannula Oxygen Support) in Gastrointestinal Endoscopy
Would patients using an anti-snoring appliance intraoperatively require less airway manipulation, interventions, and rescue maneuvers during anesthetic sedation cases compared to those who do not? The investigators will use anti-snoring appliance devices (specifically the FDA approved Zyppah) to attempt to relieve tissue obstructions that cause snoring during sleep. The application of the devices to the body is less invasive than other common intraoperative rescue airway devices (e.g. nasal trumpets and oral airways) which are not designed to be patient specific.
The Novapak study is a prospective, observational, multi-site, non-controlled, non-randomized, case-series, with a 2 week and 1-month follow-up in adults undergoing nasal/sinus surgery with Novapak Nasal Sinus Packing and Stent device used as indicated post-operatively and is being conducted to obtain clinical data on the safety and effectiveness of the Novapak device under use as intended in the device indications.
The goal of this four-part preclinical [I-II] and clinical [III-IV] trial is to compare, with randomised crossover study design [I-IV], a new medical airway device with standard procedure (biteblock or no device) for upper airway patency during sedation with intravenous propofol [I-IV]. - Page 1 of 9 [DRAFT] - The two main questions it aims to answer are if this new airway device is superior to standard procedure with respect to - maintenance of spontaneous ventilation [I] and upper airway volumes [II] at moderate and deep steady-state levels of sedation in healthy volunteer study participants, and - fewer and less lasting bedside signs of respiratory depression [III-IV], and less adjuvant use of manual airway support [III-IV] during procedural sedation (PS) according to standard of care(SOC) in study patients scheduled for colonoscopy or ureteral catheterisation under PS. Owing to the crossover study design used throughout the trial, there are no comparison groups of study participants [I-II] or study patients [III-IV].
The goal of this clinical trial is to observe the effect of low dose continuous infusion of esmolol on perioperative stress response in patients undergoing airway intervention .
Nowadays, anesthetists may encounter many patients who are not diagnosed with obstructive sleep apnea syndrome (OSAS) to undergo elective surgery. Recognition of these patients by anesthesiologists and taking necessary precautions will significantly reduce perioperative complications and mortality. STOP-BANG is a questionnaire used to predict high risk of OSAS. The aim of our study is to evaluate the clinical use of the oxygen reserve index as an early warning of possible desaturation in patients with low and high risk of OSAS according to the Stop Bang score.
