Precision Medicine in Anesthesia: Genetic Component in Opioid-induced Respiratory Depression
Respiratory DepressionThe concept of precision medicine - taking individual variability into account when planning preventions and interventions - is not new but is quickly gaining attention in this age of powerful methodology of patient characterization and development of tools to analyze large sets of data. Oncology is the most obvious field in which this information has been readily applied. Increasing focus, nationally and internationally, on developing broad databases of patient genetic information and research efforts evaluating those data will, hopefully, lead to the development and application of evidence-based data enhancing the practice of all fields of medicine. It has yet to become obvious how this information can best be applied to the field of anesthesiology. Most genomics work in anesthesia has been focused in the area of pain medicine. There is a known genetic influence on the potency of opioid-induced analgesia, however; a genetic component of opioid-induced respiratory depression has yet to be thoroughly evaluated. Respiratory depression plays a role in clinical care - from procedures requiring sedation with monitored anesthesia care to treating post-opertative pain and chronic pain - but perhaps its largest current role in the public arena is the unfortunate deaths caused by side effects due to drug overdose. Personalized medicine remains on the horizon for the field of anesthesia, but, as genetic testing becomes more affordable and mainstream in clinical practice, the potential applications are broad. Most readily would be its incorporation into development of patient specific pain regimens. Respiratory depression is a potentially lethal side effect of opioid therapy. In light of the opioid epidemic and CDC-scrutiny of opioid use, determining genetic profiles susceptible to respiratory depression could prove useful in further tailoring the treatment of pain both in the perioperative setting and in the chronic pain management setting.
Effectiveness of Bronchodilator Nebulization With and Without Noninvasive Ventilation in COPD
Chronic Obstructive Pulmonary Disease (COPD)Type 2 Respiratory FailureThe study aim to evaluate effectiveness of two bronchodilator nebulization strategies in patients with acute decompensated type 2 respiratory failure due to acute exacerbation of chronic obstructive pulmonary disease..
HEAVEN Criteria: Prediction of Difficult Airway for In- Hospital Emergency Airway Management
Respiratory FailureThe HEAVEN criteria were found valid to predict difficult airways during preclinical emergency intubations in a retrospective study. The acronym stands for Hypoxemia, Extremes of size, Anatomic abnormalities, Vomit/blood/fluid, Exsanguination/anaemia, and Neck mobility issues. This is a monocentric prospective observational study to assess the validity of the HEAVEN criteria in the in-hospital setting at a level I adult and pediatric emergency university-based hospital.
Risk Stratification of COVID-19 Using Urine Biomarkers
Covid19Urine2 moreCoronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and in infected patients, it produces symptoms which range from completely asymptomatic to those expressing severe illness. Early recognition of those developing severe manifestations allows for rapid and appropriate intervention, including admission to intensive care unit and intensive care therapy, such as mechanical ventilation. A current problem is that only limited data exist predicting the clinical course of COVID-19. This study will determine whether non-invasive urinalysis is useful in assessing and predicting the severity or clinical course of patients with COVID-19.
Treatment of Dyspnea in Do-not-intubate Patients
Acute Respiratory FailureAcute on Chronic Respiratory Failure1 morePatients with severe chronic diseases are often admitted to the hospital complaining of shortness of breath. Some of these patients decide that they do not want placement of a breathing tube in the windpipe to assist their breathing. In this situation, these patients are treated with oxygen, a variety of medications like morphine or masks that are connected to breathing machines, something called bilevel positive airway pressure (BiPAP) or noninvasive ventilation (NIV), to help with their breathing. Not much is known about how much noninvasive ventilation helps these patients, especially how comfortable they feel with it and how much their families think it helps. Our aim is to monitor use of ways to help breathing in patients who don't want a breathing tube, see how often noninvasive ventilation is used and ask surviving patients, patient's families and caregivers about their experience with noninvasive ventilation and how much it seemed to help. With our findings, we hope to improve the use of noninvasive ventilation in these patients and come up with ways to relieve their shortness of breath and provide as much comfort as possible.

Caffeine to Reduce Mechanical Ventilation in Preterm Infants
PrematurityApnea1 moreMost premature infants require mechanical ventilation for prolonged periods of time and a significant proportion of them develop Bronchopulmonary Dysplasia (BPD). Caffeine is a stimulant of the respiratory center and has been used for the treatment of Apnea of Prematurity in infants not requiring mechanical ventilation or to facilitate weaning from mechanical ventilation by starting therapy shortly before extubation. Recently the use of Caffeine in ventilated infants has been initiated earlier because of the reported reduction in BPD. However there is paucity of data supporting this practice. Because protracted mechanical ventilation and supplemental oxygen increase the risk of developing BPD, a therapy that would facilitate the reduction of the respiratory support and shorten its duration is desirable. Therefore, it is of importance to evaluate the effects of early Caffeine initiation and administration during the course of mechanical ventilation in preterm infants by means of a randomized placebo-controlled trial. Hypothesis: The primary hypothesis of this study is that early use of caffeine in mechanically ventilated preterm infants will reduce the time to first elective extubation and secondarily, that this will reduce the total duration of mechanical ventilation and oxygen supplementation, and reduce the incidence and severity of BPD. Objective: The objective of this trial is to evaluate the effects of early caffeine use during mechanical ventilation on the time to first elective extubation, total duration of mechanical ventilation and oxygen supplementation, and the incidence of BPD. Study Design: This will be a single-center prospective, randomized, double-blind, placebo controlled clinical trial. Population: Premature neonates born between 23 and 30 completed weeks of gestation, who require mechanical ventilation within the first 5 days of life will be enrolled. Infants with major congenital anomalies or small for gestational age will be excluded. Methods: Infants will be randomized within the first 5 days to receive a study drug consisting of either blinded Caffeine citrate or blinded Placebo (equivalent volume of normal saline). Infants will continue to receive the study drug until the first elective extubation.
Supplemental Parenteral Nutrition in Pediatric Respiratory Failure
Acute Respiratory Failure With HypoxiaMalnutritionOptimal delivery of nutritional support during critical illness is central to appropriate intensive care unit management, and yet fundamental gaps in knowledge exist regarding timing, route, dose, and type of nutritional support for critically ill infants and children. Understanding how to optimize nutritional support during pediatric critical illness is important because even brief periods of malnutrition in infancy result in permanent negative effects on long-term neurocognitive development. Optimized nutrition support is a way to improve morbidity for survivors of pediatric critical illness. Parenteral nutrition (PN) supplementation could improve long-term neurocognitive outcome for pediatric critical illness by preventing acute malnutrition, but has unknown effects on intestinal barrier function; a proposed mechanism for late sepsis and infectious complications during critical illness. While randomized controlled trials (RCT) support early PN in premature infants and late PN in critically ill adults, the optimal time to begin PN is unknown for critically ill infants and children. Acute malnutrition may develop within 48 hours of admission in critically ill infants and children, and repleted energy stores are predictive of survival. And yet, due to concerns for PN-associated infectious morbidity, current PICU standard of care is to supplement with PN only in children who fail to enterally feed, as late as 7 days into their admission. Delays in nutrition may have long-term effects on cognitive outcome in older infants and children. In premature infants, PN begun within hours of birth results in improved 18-month neurocognitive outcome without an increase in infectious complications. An RCT is needed to determine if early PN in critically ill infants and children prevents acute malnutrition and improves short and long-term outcomes of PICU hospitalization. The central hypothesis of this proposal is that optimized early protein and calorie delivery will improve nutritional outcomes and intestinal barrier function for critically ill infants and children. The overall purpose of this study is to evaluate the efficacy and safety of early PN as a supplement to enteral nutrition to improve nutritional delivery, nutritional outcomes, and intestinal barrier function for infants and children with acute respiratory failure who are mechanically ventilated in the pediatric intensive care unit.
Early Stage Amyotrophic Lateral Sclerosis Phrenic Stimulation
Amyotrophic Lateral SclerosisRespiratory InsufficiencyALS is is characterized by a progressive degeneration of motor neurons, leading to progressive weakness of muscles, including respiratory muscles, the diaphragm. Although specific therapy is lacking, correct respiratory therapy improves quality of life and increases survival. Substituting the failing respiratory muscles by non invasive mechanical ventilatory assistance (NIV) is the current standard of care. Intradiaphragmatic phrenic nerve stimulation is a new treatment and has been the object of a preliminary international proof-of-concept multicenter trial. This trial suggests that the intradiaphragmatic phrenic nerve stimulation slows down the rate of decline of the diaphragm. Our new hypothesis is that phrenic stimulation induces diaphragm conditioning and can delay the need for mechanical ventilation in ALS patients. We will study, during 24 months, 2 groups of 37 patients at the beginning of the respiratory dysfunction, using a intradiaphragmatic phrenic nerve stimulation in one group and a sham stimulation in the other group. Although, all the patients will be implanted, thus, at the end of the study, all the patients will receive effective stimulation.
Early Rehabilitation of COPD Patients in ICU
Chronic Obstructive Pulmonary DiseaseAcute Respiratory FailureTwenty per cent of the intensive care patients mechanically ventilated suffer from chronic obstructive pulmonary disease (COPD). These patients stay longer in Intensive Care which is more costly and they are more prone to nosocomial infection.In addition, they are longer bedridden and they develop muscular weakness.Prolonged inactivity results in respiratory and skeletal muscle weakness which curtails simple daily activity.The principal purpose of this study is to compare two types of muscular rehabilitation (electrical stimulation of the thigh and/or cycloergometer training) to classic passive mobilization of the leg.The second purpose is to analyse the effects of each type of rehabilitation on muscular fiber (structural and functional analysis) by muscular biopsies.Two hundred forty COPD patients admitted in the intensive care unit for acute respiratory failure will be randomized in 4: 1 fashion to receive passive mobilization of the legs(group 1, n=60), electrical stimulation of the thigh (group 2, n=60), cycloergometer training (group 3, n=60) or electrical stimulation of the thigh and cycloergometer training(group 4, n=60).The rehabilitation program will last 4 weeks with 5 sessions per week.In each group of patients, muscular biopsies will be done under local anaesthesia at the beginning and end of the rehabilitation programme and when they are discharged from the service.
