Cerebral Perfusion and Acute Respiratory Failure
Cerebral Blood Flow and Neonates During Acute Respiratory FailureThe most common reason for admitting babies and infants to an intensive care unit is due to respiratory distress (breathing difficulties). At present there are a number of different treatments for respiratory distress. These include drug treatments; non-invasive ventilation, where oxygen is given at high pressure to push it through the baby's lungs: ventilation where the baby is put on a breathing machine; or Extracorporeal Membrane Oxygenation (ECMO). This works by taking the blood from the body via a tube (usually) in the baby's neck, redirecting through a machine that oxygenates the blood, then returning it to the baby through another tube. Currently we know little about how different treatments have a different impact on brain perfusion (how much oxygen the brain gets). Using specialist, noninvasive ultrasound and doppler techniques, we are proposing to monitor the effect of these treatments on the brain.

Postoperative Respiratory Abnormalities
Respiratory FailureRespiratory Arrest18 moreThe study aims to determine how historical cases of respiratory abnormalities are documented by clinicians in the electronic health records (EHR) of Memorial Hermann Healthcare System (MHHS) inpatient facilities. The knowledge gained from this study will support the design of modern data-driven surveillance approach to continuously collect, monitor and timely recognize postoperative respiratory abnormalities using electronic healthcare recorded data.

Acute-on-chronic Respiratory FailureThe purpose of this study is to determine whether the new Boussignac-system of non-invasive ventilation is as good as the conventional non-invasive System in patients presenting with acute hypercapnic respiratory failure.
Magnesium for Neonatal Neuroprotection and Mothers
Premature BirthSedation During Labor and Delivery; Complications2 moreMagnesium is a treatment for mothers to protect brains of babies born early. This study investigates combined effects of magnesium and spinal or epidural anesthesia on mothers having cesareans. The investigators will use a scoring system to measure sedation and devices that subjects breath in and out of to measure breathing strength. The investigators hypothesize the combination of magnesium and anesthesia will reduce breathing strength and cause sedation. This is an observational study comparing those having magnesium and anesthesia with those just having anesthesia. Routine medical care will not be altered. Results will hopefully allow anesthesiologists to provide better patient care.
Etiologies and Outcomes of Acute Respiratory Failure in Community
Respiratory FailureAcute respiratory failure (ARF) remains a common reason for admission to the intensive care unit (ICU). ARF to be present in 32% of patients on ICU admission, with a further 24% of patients developing ARF during the ICU stay. A total of 56% of all ICU admissions for a length of >48 h had ARF at some point during their stay. The incidence of ARF was from 88.6 to 137.1 hospitalizations per 100,000 residents. The incidence of ARF was found to increase nearly exponentially with each decade until age 85 years. However, there is still paucity data about etiology and outcomes of acute respiratory failure happened in community. Mortality of ARF in critically ill patients is between 40% and 65%. Independent hazards for ARF mortality include older age, severe chronic co-morbidities (HIV, active malignancy, cirrhosis), certain precipitating events (trauma, drug overdose, bone marrow transplant), and multiple organ system failure (MOSF) [7-9]. Mortality has also been associated with acute lung injury or bilateral infiltrates on chest radiograph, and with an elevated acute physiology score. ARF patients form a large percentage of all ICU admissions and many factors might influence the final outcomes. With the high incidence of ARF in ICU, any improvement in the outcome of such population is likely to have marked effect on intensive care resource allocation. We wish this study may provide some valuable information about acute respiratory failure in community and improve the outcome of these patients.
Is Venous to Arterial Conversion (v-TAC) of Blood Gas Reliable in Critical Ill Patients in the ICU?...
Respiratory InsufficiencyMetabolic Disease5 moreObjective: 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.
Conduct of Nasal High Flow Oxygen in Acute Respiratory Failure
Acute Respiratory Failure With HypoxiaHypoxemiaAlthough many studies have investigated the clinical benefits of nasal high flow during acute hypoxemic respiratory failure, there is no data (and even less so recommendations) on how to best conduct this technique, including its initiation and its weaning periods. Investigators will assess in a multicenter, observational study, the way clinicians use nasal high flow therapy in patients with acute respiratory failure in order to try identify one or more strategies that may be then compared in an interventional study.
