Active clinical trials for "Respiratory Aspiration"

The aim of the current study is to compare the efficacy and safety of Salmeterol/Fluticasone 50/500 mcg Inhalation Powder treatment administered via Capsair twice daily and original product Seretide Diskus 500 mcg Inhalation Powder treatment twice daily in patients with moderate-severe COPD. Spirometric measurements will be performed at 12 different time points at pre-treatment and post-treatment (5. min, 15. min, 30. min, 1. hr, 2. hr, 3.hr, 4.hr, 6.hr, 8.hr, 10.hr and 12.hr) during the treatment visits of 11-weeks study period.

The purpose of this study is to evaluate the quantity of propofol administered with Xenon in two inspiratory concentrations, to maintain comparable depth of anaesthesia during the maintenance period of general anaesthesia.

In this study, patients who are ready for extubation and indicated for high-flow nasal cannula therapy after extubation will be enrolled, the investigators would measure the patient peak tidal inspiratory flow (PTIF) pre and post extubation to explore the correlation between the two PTIFs. Moreover, different HFNC flows would be applied, to explore the patient response in terms of oxygenation and lung aeration to different flow ratios that matched and are above post-extubation PTIF.

The objective of the present study is to obtain information about the safety and tolerability of multiple increasing doses of BIIX 1 XX and to obtain preliminary pharmacokinetic data

In this clinical trial will be checked, whether 2 hour ventilation with xenon has neuroprotective effects in patients with out of hospital cardiac arrest and successful cardiopulmonary resuscitation

This study will examine whether treatment of inferior turbinates in patients with continued symptoms of obstructive sleep apnea, sleep related breathing disorder, snoring, disturbed sleeping, open mouth breathing, and upper airway resistance syndrome after tonsillectomy and adenoidectomy will improve these symptoms and should be included in the treatment paradigm for treatment of sleep related breathing disorders in infants, children, and adolescents.

The mechanical ventilation weaning must begin as early as possible to limit its complications and requires a spontaneous breathing trial (SBT) before the separation from the ventilator to the patient. However, some patients fail this test and cannot be extubated. The main causes are pulmonary edema and diaphragmatic dysfunction. Predicting the risk of failure before carrying out the SBT makes it possible to anticipate a failure of the extubation and to adapt the therapies as well as possible. To assess the risk of pulmonary edema, cardiac preload, which corresponds to the end-diastolic filling volume of the ventricle, can be estimated using simple tests as the passive leg raising test before an SBT. However, this test requires tilting the patient's trunk and raising the lower limbs to 45°, and is not practical, especially in intensive care. The Müller maneuver, which allows maximum inspiratory pressure measurement via a one-way valve connected to the intubation tube, is currently used in routine care for diaphragmatic assessment. The endothoracic depression induced by this test is likely increasing venous return and cardiac output in patients with a reserve of preload, i.e. in preload-dependent patients. This test would be an easy alternative to the passive leg raising test used in current practice. The objectif is to assess whether the presence of an independant prelaod state, as detected by the absence of increased cardiac output during the Müller maneuver, is associated with the occurence of pulmonary edema during weaning from mechanical ventilation. The study consist in the measurement of cardiac output before and after the passive leg raising test and the Müller maneuver, then measurement of cardiac output before and after an SBT. A transthoracic ultrasound and a blood sample with dosage of proteins and hemoglobin will be carried out initially and then at the end of the SBT as part of routine care. The investigators hypothesize: The Müller maneuver induces a greater increase in cardiac output in patients in a state of preload dependancy than in patients in a state of preload independancy. The absence of documented preload dependancy during a Müller maneuver is associated with the occurrence of pulmonary edema during an SBT. The investigators included patients : > 18 years old, conscious patient, with health insurance, placed under mechanical ventilation for at least 24 hours ; In whom it was decided to perform a passive leg raising test and an SBT. The investigators excluded pregnancy, patient with chest tube, particpation in another interventional study, tracheostomy, patient under legal protection.

This study is a randomized controlled trial to evaluate whether EEG-guided calibration of inhalation agents can reduce occurrence of EEG discontinuity in infants during general anesthesia.

The usefulness of re-oxygenation after inhalation of 50% nitrous oxide and 50% oxygen premix (Kalinox 170 bar) during dental care is studied and the pollution resulting from administration of Kalinox is also investigated.

The purpose of this study is to determine if, once a favorable dose of TI Inhalation Powder is established for either a type 1 or 2 patient, based on a average diabetic meal, the patient's favorable dose can be used safely, regardless of change in meal carbohydrate content. Patients were randomly assigned to various carbohydrate loads (0%, 50%, 100%, 150% or 200%). The 100% carbohydrate load was determined based upon their standard insulin dose for their normal meal.
