Filter by:Patients were classified into two equal groups using the presence or absence of hypertension during pregnancy into: hypertensive group (BP>140/90) and normotensive group (BP≤140/90. The surgical time intervals are assessed and classified the patients accordingly into short and log time interval subgroups (induction of regional anesthesia to delivery (I-D), initial skin incision to delivery (S-D), and uterine incision to delivery (U-D)
The objective of the study is to determine whether adjunctive mask of our design (Double Trunk Mask - DTM) has an effect on increasing arterial pressure in Oxygen (PaO2) diagnosed with severe hypoxia.
- Patients with Motor Neurone Disease (MND) admitted to Lane Fox Unit /Royal Brompton Hospital and/or reviewed in Lane Fox Unit /Royal Brompton Hospital clinics and/or outreach review will be approached for participation in the study - Physiological assessment and measurement of arterial stiffness will be performed in all patients at baseline and after the use of non invasive ventilation for 6 weeks. - MND patients not requiring mechanical ventilation will serve as controls since non invasive ventilation cannot be withheld from MND patients in type II respiratory failure. - Data will be analysed to look for differences between groups, relationships in baseline or change from baseline in respiratory physiological measures, inflammatory indices, breathlessness, and arterial stiffness. - Age, Height, Weight - History and Physical Examination - Evaluation of dysponea: mMRC, Borg Scale (Seated-Supine) - Amyotrophic lateral sclerosis functional rating scale (ALSFRS-R) - Sleep Disordered Breathing in Neuromuscular Disease Questionnaire (SiNQ-5) - 24 hour blood pressure monitor - Carotid-femoral pulse wave velocity - Respiratory Muscle Strength - Maximal Inspiratory Pressure, Maximal Expiratory Pressure, and Sniff Nasal Inspiratory Pressure - Spirometry - FEV1 and FVC - Arterial Blood Gas - CRP and fibrinogen (clinically) - Breathe CO exhale
Multicenter, phase IV, non-superiority, registry-based, randomized controlled trial. Patients starting long-term oxygen therapy (LTOT) are randomized between LTOT prescribed 24 h/day or 15 h/day using the Swedish Register for Respiratory Failure (Swedevox). Clinical follow-up and concurrent treatments are according to routine clinical practice. The main endpoints of mortality, hospitalizations, and incident disease are assessed using Swedish registry data, with expected complete follow-up. Patient-reported outcomes are assessed using a posted questionnaire at 3 and 12 months. The study is managed by the Uppsala Clinical Research Centre (UCR).
The purpose of this study is to evaluate the oxygen saturation accuracy performance of Belun Ring Oximeter placed on the index fingers during non-motion conditions
The effect of biphasic positive airway pressure (Bi-PAP) at individualized pressures on the postoperative pulmonary recovery of morbidly obese patients (MOP) undergoing open bariatric surgery (OBS) and possible placebo device-related effects (sham-Bi-PAP) were investigated.
- Question: Ventilatory strategy to counterbalance the effect of one lung ventilation during thoracic surgery. - Findings: the open lung approach improved oxygenation and lung compliance, reducing respiratory system driving pressure and transpulmonary driving pressure. - Meaning: patients undergoing thoracic surgery during one lung ventilation may benefit of an open lung approach strategy to avoid ventilator lung injury.
SCENARIO: Hypoxemia is one of the most common adverse events during the induction of general anesthesia and may culminate with more serious complications such as cardiac arrest and death. Pediatric patients, due to their anatomical and physiological characteristics, are more likely to develop hemoglobin desaturation levels. Some preventive strategies are used during this period to reduce the chances of occurrence of adverse event. Continuous Positive Airway Pressure (CPAP) may be useful during anesthetic induction in delaying the drop in oxygen levels in the blood by increasing this body gas reserves. OBJECTIVES: To assess the effectiveness of CPAP during anesthetic induction in increasing apnea time until hemoglobin saturation falls to 95% in children undergoing general anesthesia for elective surgery. METHODS: Phase III, parallel, randomized clinical trial to be developed at the Teaching Hospital of the Federal University of Pernambuco. Patients (72) are divided into two groups (36 in each) in which all patients will spontaneously ventilate: group C will receive CPAP and group A will use the open system. Children of pre-school age with physical status I or II, according to the American Anesthesia Society, candidates for elective surgery under general anesthesia will be included. Patients with pre-existing parenchymal lung disease, cyanotic children or patients with oxyhemoglobin saturation <95% prior to anesthetic induction and recent history (<4 weeks) or active upper respiratory tract infection will be excluded. The descriptive statistical analysis will be carried out through measures of central tendency and dispersion for quantitative variables and via distribution of frequencies for qualitative variables. ETHICAL ASPECTS: This work will respect human rights, principles of bioethics, the resolution 466/2012 of the National Health Council and the statement from Helsinki. Submission and approval by the research ethics committee is required prior to data collection. KEYWORDS: Continuous Positive Airway Pressure, Hypoxia, General Anesthesia
THRIVE (Transnasal Humidified Rapid-Insufflation Ventilatory Exchange) refers to the use of high-flow nasal cannula to augment the ability to oxygenate and ventilate a patient under general anesthesia. The use of high-flow nasal cannula oxygen supplementation during anesthesia for surgical procedures has been a recent development in the adult population, with limited data analyzing the pediatric population. This study will determine whether high flow nasal cannula oxygen supplementation during surgical or endoscopic procedures can safely prevent desaturation events in children under anesthesia.
Aim of this study is to investigate the effects of an Oxymizer pendant nasal cannula in hypoxemic patients with idiopathic pulmonary fibrosis during walking.
