Enteral Feeding Composition and Acute Respiratory Failure

Acute Respiratory Failure

This study aimed to investigate the effect of enteral feeding's macronutrient composition on inflammatory mediators, oxidative stress and outcomes in Intensive Care Unit (ICU) patients with acute respiratory failure. In this double-blind randomized control trial, 42 patients of both sexes and diagnosed with acute respiratory failure in ICU that receive enteral feeding, will be randomly assigned to three groups of 14 each. First Intervention group; high-protein low-carbohydrate diet with high olive oil, the second intervention group; high-protein low-carbohydrate diet with high sunflower oil and control; high-protein kitchen formula. Intravenous levels of uric acid, high sensitive C-Reactive Protein (hs-CRP), Interleukin 6 (IL-6) and Total Antioxidant Capacity (TAC) measured at days 0 and 10. As well as, organ failure, duration of ventilation, length of ICU stay and mortality rates will be evaluated.

Pulmonary And Renal Support During Acute Respiratory Distress Syndrome

Acute Respiratory Distress SyndromeAcute Renal Failure

In patients presenting with the acute respiratory distress syndrome (ARDS), mechanical ventilation with low tidal volume (6 ml/kg predicted body weight) is the current gold standard for supportive care. However, despite a relative low tidal volume, approximatively one third of patients will experienced tidal hyperinflation, a phenomenon known to induce pulmonary and systemic inflammatory response. A further reduction of the tidal volume to 4 ml/kg (PBW) will prevent pulmonary area from tidal hyperinflation. As a result, hypercarbia and respiratory acidosis are commonly observed with such very low tidal ventilation. Extra corporeal CO2 removal is one of a mean to normalize arterial CO2 tension. Patients with ARDS also frequently develop acute renal failure which may required Renal Replacement Therapy. Some data suggests that starting early the RRT may favor outcome. The investigators hypothesized that a strategy combining ECCOR and RRT early in the course of patients presenting ARDS and acute renal failure will allow the tidal volume to be further reduced, providing lung protection, while avoiding the arterial CO2 tension to be increased. For this purpose, the investigators sought to evaluate the safety and efficacy of adding a membranel oxygenator within an hemofiltration circuit, either upstream or downstream of the hemofilter.

Effect of Different Ventilatory Strategies on Cardiac Function in Patients With Acute Respiratory...

Respiratory Distress Syndrome

Mechanical ventilation with low tidal volume (about 6 ml.kg-1) reduces mortality in ALI/ARDS patients respect to high tidal volume ventilation (about 12 ml.kg-1). This finding is usually explained by alveolar tidal overdistension associated to high tidal volume. Stretch-induced lung injury may trigger a cytokine-mediated inflammatory response. This may contribute to the development of systemic inflammatory response and multiple system organ failure and death. High tidal volume strategies might affect organ function by pathways not mediated by inflammatory response. It is well recognized the inverse relationship between tidal volume and cardiac output during mechanical ventilation. Nevertheless there are no clinical studies about cardiac output changes induced by low (6 ml.kg-1) and high tidal volume (12 ml.kg-1) in ALI/ARDS patients. The study hypothesis is that high tidal volume ventilation reduces cardiac output in ALI/ARDS patients respect to low tidal volume strategy. Thereafter reduced hemodynamic impact could explain beneficial effect of low respect to high tidal volume ventilation. If study hypothesis is confirmed, other studies should define the main cause of mortality reduction related to low tidal volume strategies and if appropriate hemodynamic monitoring and support should be required when low tidal volume strategies are harmful (i.e. traumatic brain injury).

Feeding the Critically Ill During Phases of Altered Redox Status

Acute Respiratory Distress SyndromeOxidative Stress2 more

The FEDOX trial is a prospective randomized clinical trial exploring oxidative stress as a mechanism of harm to explain the negative outcomes found in feeding trials that achieved caloric exposure commensurate with the nationally recommended guidelines. Due to its impact on energy metabolism, we will also explore low T3 syndrome's relationship to this mechanism. Finally, we will explore circadian patterns of diurnal/nocturnal TSH fluctuation as a potential biomarker to indicate this mechanism of harm has subsided. This 7-day prospective randomized clinical trial is designed to address the following specific aims (SA) in ICU patients (n=40) with systemic inflammatory response syndrome. SA1) Determine whether provision of enteral nutrition (EN) at 100% of levels in Nationally Recommended Guidelines NRG (25-30 kcals/kg, 100%NRG) early in critical illness increases reactive oxygen species (ROS) production compared to EN at 40% of NRG levels (10-12 kcals/kg, 40%NRG). Subjects will be fasted overnight and randomized to receive either 100% NRG or 40%NRG for 7 days. Plasma F2-isoprostanes will be measured daily and compared between groups through repeated measures analysis. SA2) Determine if EN at 100%NRG interrupts the critical illness induced low T3 syndrome and subsequently further increases the ROS production compared to 40%NRG. Serum thyroid parameters (T3, T4, rT3, TSH) with be measured daily and compared between groups as above. Mediation analysis will be used to determine the proportion of the effect of nutrition group on F2-isoprostane production explained by each thyroid parameter. SA3) Determine if the return of diurnal/noctural fluctuations in TSH is associated with decreased nutrition-induced ROS production. Plasma TSH will be measured twice per day at 0300 and 1800hrs to determine TSH fluctuation. The interaction effect between TSH fluctuation and nutrition group on F2-isoprostane production will be assessed through repeated measures analysis. This study provides vital mechanistic insight into the impact of feeding on oxidative stress during the first week of critical illness, represents an important first step in determining the safest timing and dosage of nutrition support, and sets the foundation for future larger clinical trials on these topics.

Breastfeeding Infants Receiving Respiratory Support Trial

Intensive CareNeonatal5 more

The purpose of this study is to assess whether two methods of breathing support in babies called 'Humidified High-Flow Nasal Cannula' oxygen (HHFNC) and 'nasal Continuous Positive Airways Pressure' (nCPAP) are compatible with breastfeeding. Many babies who are premature or unwell after birth require help with their breathing. This is often achieved by blowing a continuous flow of air through the nose and down into the lungs in order to reduce the amount of effort the baby needs to inflate the lungs during breathing. Currently some centres allow babies to breastfeed whilst undergoing breathing support whilst other centres do not in case there is an increased risk of choking or other harmful events. In the latter case, babies are fed using a nasogastric tube (NGT) that runs from the baby's nostrils into their stomach. At this centre, babies are allowed to breastfeed whilst simultaneously on either HHFNC or nCPAP. This is because the concerns over the choking risk are not evidence based. This study aims to conclusively prove that thisfeeding protocol is safe and then to expand into other areas of research to find out the following: Whether breastfeeding during nCPAP or HHFNC leads to babies establishing full breastfeeding sooner (and subsequently reduce the length of their stay in hospital) What the effects of breastfeeding of nCPAP or HHFNC are on a baby's parents (e.g. whether it enhances bonding) If nCPAP and HHFNC have different effects on breastfeeding As part of this study the investigators will observe stable babies on nCPAP or HHFNC during breastfeeding episodes. The investigators will monitor the babies for signs of distress or instability and whether they are more stable when breastfeeding is not occurring. This will be compared to an episode where the same baby is fed by NGT to see which technique is better.

Human Umbilical Cord Mesenchymal Stem Cells (MSCs) Therapy in ARDS

Acute Respiratory Distress Syndrome

Acute respiratory distress syndrome (ARDS) is a devastating inflammatory and destructive disease in critical ill patients. Preclinical studies have shown a promising perspective of mesenchymal stem cells (MSCs) therapies in ARDS. But the safety and efficacy of umbilical cord MSCs (UCMSCs) have not yet been convinced in clinical trails. This study will explore the safety and life-rescue potential of UCMSCs in refracotry ARDS.
