Filter by:Despite few scientific evidence that could support the use of ketamine in adult patients undergoing acute bronchospasm requiring mechanical ventilation (MV), ketamine is largely employed in this setting. The aim of this study is therefore assess more definitively the real benefit of using ketamine in patients with severe bronchospasm, requiring ICU stay and need for MV in order to establish or refute the use of this drug as "standard therapy" in these cases.
Asthma is characterized by recurrent episodes of bronchospasm, bronchial hyperresponsiveness and chronic airway inflammation and pharmacological treatment for this condition is done with bronchodilators and anti-inflammatory.
Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo lung and flail chest surgery.
Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo abdominal and limb operations. In a pilot study arm electrical impedance tomography is tested in patients receiving osteosynthesis of serial rib fractures.
The purpose of this study was to evaluate whether 2 puffs of fixed combination of aerosolized 120 mcg salbutamol sulphate (equivalent to 100 mcg of the base) + 20 mcg ipratropium bromide confers significant additional protection against metacholine induced bronchoconstriction in asthmatic atopic patients when compared to 2 puffs of aerosolized 100 mcg salbutamol alone.
Background There is no unanimous opinion about a lung-protective strategy in cardiac surgery. Small randomized clinical and animals trials suggest that ventilation during cardio-pulmonary bypass (CPB) could be protective on the lungs. This evidence is based on surrogate end-points and most of studies are limited to elective coronary surgery. According to the available data, an optimal strategy of lung protection during CPB cannot be recommended. The purpose of the CPBVENT study is to investigate the effectiveness of different ventilation strategies during CPB on post-operative pulmonary complications. Trial design The CPBVENT study will be a single-blind, multicenter, randomized controlled trial. We are going to enroll 780 patients undergoing elective cardiac surgery with planned use of CPB, aortic cross-clamping and two lung ventilation. Patients will be randomized into three treatment groups: 1) no ventilation during CPB; 2) continuous positive airway pressure (CPAP) with positive end-expiratory pressure (PEEP) of 5 cmH2O during CPB; 3) ventilation with 5 acts/minute with tidal volume of 2-3 ml/Kg and a PEEP of 3-5 cmH2O during CPB. The primary end-point will be the incidence of a PaO2/FiO2 ratio <200 until the time of discharge from the ICU. The secondary end-points will be the incidence of post-operative pulmonary complications and 30-days mortality. Patients will be followed-up to 12 months after the date of randomization. Summary The CPBVENT Trial will determine whether different ventilation strategies during CPB will improve pulmonary outcome in patients undergoing cardiac surgery.
The purpose of the study is to compare the pharmacokinetics of nebulized amikacin administered with three vibrating mesh nebulizers coupled with a single limb circuit bilevel ventilator in healthy volunteers. Following our previous in vitro study, our hypotheses are that the pharmacokinetics varies among the devices tested and that a most efficient device can be identified.
The study will be conducted in two hospitals of the same geographic area. It will be included children <3-years-old with recurrent wheezing attacks, confirmed by the review of the medical records, in the previous 12 months or a shorter time for those younger than one year.
This will be a double-blind placebo-controlled study in which we plan to study 40 competitive endurance athletes. We will conduct an exercise test to evaluate maximal oxygen uptake and 2 exercise challenge tests to provoke EIA. Prior to the exercise challenge tests the athletes will randomly receive inhaled placebo or inhaled ipratropium bromide. We will compare the athletes' airway response to the exercise challenge with and without the active drug.
There is increased frequency of asthma in obese patients. This study is trying to find out if there is a difference in the presence of bronchospasm during anesthesia in obese and non obese patients.
