Filter by: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.
To compare the duration of mechanical ventilation and the weaning period between two groups of patients managed with either Standard Care or with mechanical ventilation adjusted according to the Beacon Caresystem, in patients receiving mechanical ventilation for more than 24 hours
ICU care of patients considered "palliative" but without contraindications to admission to intensive care, for whom a do-not intubate order decision was made upon admission represents a particular target for non-invasive oxygenation techniques. The benefits of non invasive ventilation (NIV) in this population are debated especially in cancer patients. The more recently used nasal humidified high flux canula oxygenation (HFNC) therapy may have benefits over NIV in these patients. It is supposed to have better tolerance and could allow better compliance and thus higher efficiency. These potential benefits are major for such a population for which tolerance and symptomatic relief are priority goals
Controlled mechanical ventilation may lead to the development of diaphragm muscle atrophy, which is associated with weakness and adverse clinical outcome. Therefore, it seems reasonable to switch to partially supported ventilator modes as soon as possible. However, in patients with high respiratory drive, the application of partially supported modes may result in high lung distending pressures and diaphragm injury. Recently, the investigators published a study that demonstrated that a low dose of neuromuscular blocking agents (NMBA) facilitates lung-protective ventilation and maintains diaphragm activity in intensive care unit (ICU) patients. That study was conducted in a small (N=10), selected group of patients and partial neuromuscular blockade was applied for only 2 hours (proof-of-concept study). Therefore, further research has to be done before this strategy can be applied in clinical practice. The primary goal is to investigate the feasibility and safety of prolonged (24 hours) partial neuromuscular blockade in patients with high respiratory drive in partially supported mode. The secondary goals are to evaluate the effect of this strategy diaphragm function, lung injury, hemodynamics and systemic inflammation.
Pulmonary transplantation (PT) is a therapeutic option now accepted in the management of selected patients who have reached the irreversible and terminal stage of their chronic respiratory insufficiency. Its main indications are: cystic fibrosis and other bronchial diseases, emphysema , interstitial lung diseases with idiopathic pulmonary fibrosis in the foreground, and severe pulmonary hypertension. The evocation of osteo-articular and musculotendinous pain symptoms in the aftermath of PT is frequent and very diversified. These complications are poorly codified and hinder the rehabilitation and early resumption of physical activity and sports. Few data are available on this subject in the literature. Following transplantation, improvements in respiratory function, quality of life, and exercise capacity are observed, with large inter-individual variations; Patients are encouraged to resume physical activity, initially as part of a rehabilitation exercise. Among the factors limiting exercise, some have been more widely studied, such as muscular deconditioning related to pre-existing chronic respiratory insufficiency , prolonged stay in intensive care, side effects of transplant-related treatments (corticosteroids and immunosuppressants). Pain is also a factor limiting the recovery of physical activity and quality of life. Pain related directly to thoracotomy surgery has been explored but there is little data available on musculoskeletal pain. The purpose of this study is to better understand the musculoskeletal pain occurring in the aftermath of a lung transplantation. Conducting this study for a period of 1 year will allow you to move away from the immediate post-transplant time, and the pain associated with the transplant will no longer have any interference. The main objective of our study is to better know the prevalence of algic manifestations of the musculoskeletal system (osteo-articular, musculotendinous ...) occurring in the year following a TP, and may constitute a brake on the rehabilitation of the musculoskeletal system. effort and recovery of physical activity or sport.
Children who are in a hospital with respiratory distress often have difficulty breathing, have thick mucus, and may find it hard to eat normally. Sometimes physical therapy is used to treat these children, but it is not entirely known which methods help the children's condition. The aim of this study is to evaluate the most common physiotherapy treatment method that is currently in use in Sweden for infants who are hospitalized with a lower respiratory infection.
Humidified high flow nasal oxygen therapy decreases dilution of the inhaled oxygen and, by matching patient's peak flow, allows accurate delivery of the set FiO2 throughout the whole inspiratory phase.The purpose of this study is to determine the impact of hign-flow nasal therapy on pediatric hypercapnic respiratory failure by comparing with nasal continuous positive airway pressure.
Objective: Arterial blood gas (ABG) is essential in the clinical assessment of potential acutely ill patients venous to arterial conversion (v-TAC), a mathematical method, has recently been developed to convert peripheral venous blood gas (VBG) values to arterialized VBG (aVBG) values. The aim of this study is to test the reliability of aVBG compared to ABG in an intensive care unit (ICU) setting. Method: Consecutive patients admitted to the ICU with pH values <7,35 or >7,45 are included in this study. Paired ABG and aVBG samples are drawn from patients via arterial catheter, central venous catheter and/or peripheral venous catheter and compared.
The failure of extubation in pediatric resuscitation is most often described as the need for reintubation within 48 hours after extubation. The failure rate of extubation in pediatric intensive care varies in the literature there is between 4 and 22% failures. These failures result in increased mortality, morbidity with a use of larger tracheostomy, a prolonged residence time. The extubation is codified in adult resuscitation and tends to be increasingly in pediatric resuscitation. In the pediatric intensive care unit of Hautepierre, a extubation protocol already exists for some time, and was prepared to go. the current literature data. It allows the harmonization of practices in service (previously left to the discretion of each doctor). The investigators are looking to see if the protocol used systematically in the service enables a reduction in the incidence of occurrence of failures of extubation.
The failure of extubation in pediatric resuscitation is most often described as the need for reintubation within 48 hours after extubation. The failure rate of extubation in pediatric intensive care varies in the literature there is 4 to 22% failure. These failures result in increased mortality, morbidity with a use of larger tracheostomy, a prolonged residence time. Some risk factors are well defined in the literature as the duration of intubation, ENT and neurological history, the persistence of a respiratory disease, a high level of sedation. Other factors are more controversial as age, ventilatory parameters just before extubation before extubation blood gases, the interest of a leak test. Also pediatric populations are extremely heterogeneous, so the investigators would like to highlight to extubation failure risk factors in Hautepierre pediatric ICU to better support these high-risk children.
