Active clinical trials for "Nasal Obstruction"

Awake intubation is a recommended safety procedure in specific cases where the intubation or ventilation before general anesthesia is at risk. Numerous techniques to allow awake intubation have been described, such as pure awake technique, local anesthetics or intravenous sedation for example. Hypnosis is used for various operating room techniques and surgeries. The investigators aim to analyze the feasibility of awake laryngoscopy and intubations on patients placed under hypnosis alone.

Intubation with an unchanneled videolaryngoscope mandates the use of a stylet. The Gliderite is a stylet specially designed for videolaryngoscopes. The investigators aim to compare the efficacy of a new designed bougie for intubation in patients with simulated difficult airways.

Airtraq sp has been proven effective for intubating patients presenting with difficult airway. The Airtraq sp allows visualisation of the tracheal inlet only for the intubator. By adding a smartphone with a dedicated app (Airtraq Mobile) to the Airtraq sp, the visualisation of the tracheal inlet is possible for all the airway providers. The investigators aim to demonstrate that the addition of the Airtraq Mobile app improves success rate of intubation (primary endpoint), as well as confort of the airway provider, shortens time for intubation and reduces injury to the patients.

Nasal obstruction is one of the majors concerns in reduction rhinoseptoplasty, because it affects quality of life and surgical outcomes. Is the association of middle third grafts with reduction rhinoseptoplasty responsible for an increase in quality of life related to nasal obstruction when compared to reduction rhinoseptoplasty without the placement of these grafts?

Patients suffering from pathology of posterior eye chamber such as diabetic retinopathy, retinal detachment, traumatic eye injury, retained lens fragments, macular hole, pucker, dislocated intraocular lens after cataract surgery or vitreomacular traction are often subjected to pars plana vitrectomy (PPV). PPV is minimally invasive endo-microscopic operation usually performed in topical anesthesia combined with sub-Tenon or retrobulbar block done by surgeon, supplemented by intravenous analgo-sedation given by anesthesiologist. Continuous infusion and dose adjustment of intravenous anesthetics applied should procure moderate sedation and preservation of patients' spontaneous ventilation. However, despite carefully applied anesthetics and standard low-flow nasal oxygenation (LFNO) (5 L/min O2 via nasal catheter), inadequate spontaneous breathing can occur leading to low blood oxygen level (hypoxia). Obese patients are susceptible to hypoxia and hypercapnia (high CO2 blood level) during analgo-sedation. Respiratory instability of obese patients is often associated to their subsequent circulatory instability (heart rate and blood pressure disorders). On the other hand, high-flow nasal oxygenation (HFNO) is usually used during anesthesia induction when difficult maintenance of airway patency is expected, in intensive care units during weaning patients from mechanical respirator and in postanesthesia care units during awakening from anesthesia. It can deliver 20 to 70 L/min, up to 100% inspiratory fraction of O2 (FiO2) to patient. High oxygen/air flow produces 3-7 cmH2O of continuous pressure in patients' upper airways therefore providing better oxygenation. Oxygen/air mixture delivered by HFNO is humidified and heated, thus more comfortable to patient than dry and cold LFNO. Aim of this study is to compare effect of HFNO to LFNO during intravenously applied standardized analgo-sedation given for PPV in obese adult patients. Investigators hypothesize that obese patients, whose breathing pattern is preserved, receiving HFNO vs. LFNO during standardized analgo-sedation for PPV will be more respiratory and circulatory stable, preserving normal blood O2 and CO2 level, breathing pattern, heart rate and blood pressure.

The purpose of this clinical trial is to evaluate safety and efficacy of TnR mesh for patients who need nasal septoplasty for septal deformity with nasal obstruction.

Pathological-anatomical changes in the nasal cavity (nasal septum/perforation, mucosal hypertrophy) negatively affect nasal airflow, increase resistance - cause nasal obstruction and are often an indication for surgery. The aim of the study is to examine nasal airflow parameters after septoplasty and turbinoplasty .

Sixty subjects will take part in this study. The subjects will be randomly assigned in a 1:1 ratio between the two arms of study. (Group A: Solution of Luffa Nasal Operculate 5mg/mL, Group B: saline). The subjects will use the study medication or comparative, according to their randomization, for a treatment period of 3 to 7 days. A follow-up visit will be made 15 days after initiation of treatment.

Gastroesophageal(GERD) reflux disease is a very common problem among pediatric population and has be proved to contribute in numerous otolaryngological manifestations. Trails of empirical treatment of antireflux medications is often used as a diagnostic test. However, the investigators believe GERD can cause rhinitis and nasal obstruction. Nasonex is considered as first line treatment for nasal obstruction. Hence, the proposed study aims to define the relationship between GERD and rhinitis using randomize control trial where one group of patients will receive nasonex and placebo, while the other group will receive nasonex and antireflux medications.

Pain is an unpleasant sensory experience associated with actual or potential tissue damage. Acute pain management is an important aspect of perioperative anesthetic care. Moreover, it is the most important factor related to patient discomfort after surgery. Adequate pain management, ideally resulting in the complete absence of postoperative pain, not only provides comfort to patients, but may also contribute to improved healing and a reduction in the incidence of postoperative complications. Inadequate postoperative analgesia has been shown to contribute to adverse outcomes, including, but not limited to, immunosuppression, hyperglycemia, poor rehabilitation, and progression to chronic pain.
