In December 2019, a sudden public health incident (the corona virus disease [COVID-19] epidemic) occurred in Wuhan, China. Clinical features of those with pneumonia include fever and cough, and in many cases a sudden and accelerating respiratory distress originated from interstitial pneumonia . Many hypotheses have explained hypoxemia in COVID-19 patients, such as hyperimmune reaction to viral infection and cytokine storm that leads to serious lung tissue and alveolar damage or even direct viral insult . Mortality are as high as 15% in critically ill patients requiring intensive care unit admission and oxygen therapy , suggesting an urgent need to try therapeutic interventions in addition to supportive treatment. There is more than one type of hemoglobin. In adults, Hb A or Adult hemoglobin which is the main hemoglobin in the blood. But there is another type of hemoglobin called fetal hemoglobin. Fetal hemoglobin (hemoglobin F, Hb F, or α2γ2) is the main oxygen carrier protein in the human fetus. and the levels remain high after birth until the baby is roughly 2-4 months old . Hemoglobin F has a different composition from hemoglobin A and higher affinity to oxygen . At birth, hemoglobin F accounts for 50-95% of the infant's hemoglobin and at around 6 months after birth, hemoglobin A becomes the predominant type.The key feature that allows hemoglobin F to bind more strongly to oxygen is by having γ subunits (instead of β, in Hb A for example). 2,3-BPG interacts much more with hemoglobin A than hemoglobin F . A hypothesis for the low incidence of the COVID-19 infection in pediatric is the presence of fetal hemoglobin (HbF) . In a preliminary study about the prevalence of hemoglobinopathies in different countries and the mortality rate of COVID-19, it appears that the mortality is lower in countries with a higher prevalence of hemoglobinopathies . Mice treated with GBT1118 (a compound that enhances the oxygen affinity of hemoglobin) showed a sustained significant increase in SpO2 over 4 h of hypoxia exposure. People with haemoglobinopathies like sickle cell anemia or beta-thalassemia attributed with high amount of fetal hemoglobin, become mostly asymptomatic or have mild symptoms . The volume of umbilical cord blood varies from 50 ml to 140 ml with a mean of 85 ml rich in fetal hemoglobin . Mesenchymal stem cells (MSCs) have been widely used in the clinical setting, not only for autoimmune diseases but also for infectious diseases , and their safety and effectiveness have been well elucidated . As a noninvasive treatment, hUC-MSC therapy is a very effective and promising method for clinical application and promotion to treat severe COVID-19 the investigators offer a solution by increasing fetal hemoglobin by cord blood containing fetal blood transfusion in the critical patients as a trial to combat the course of the disease and minimize the morbidity especially in sever cases who suffer from desaturation until suppression of the immune dysregulation and avoidance of the impending death.
This will be a five year study that will be a prospective, randomized, controlled trial (RCT) to assess the effect of a virtual early intervention care delivery model in the provision of therapy to enhance the neurodevelopmental trajectory of infants with brain injury. In addition, the investigators will enhance understanding of the social and parental contributors to outcomes and the early health economic impact of a virtual clinic. The results of this study will help inform the design of a larger, multi-center randomized controlled trial.
Vital signs of postoperative patient are monitored intensively in post-anesthesia care unit or intensive care unit, but the frequency of surveillance decreases in typical surgical wards. The continuous pulse oximetry in surgical wards is known to be useful in detection and prevention of hypoxemia, reducing complications caused by postoperative respiratory depression. However, continuous monitoring is not conducted, due to shortage of equipment and personnel. Recently, wearable device for measuring pulse oxygen saturation, which is inexpensive, applicable to patients with mobility, and can be monitored continuously through wireless connection, has been supplied. In this study, the investigators evaluate the effect of continuous monitoring of oxygen saturation with wireless device(MASIMO Radius-7) on postoperative patients who are transferred to general wards, and evaluate the effect of early intervention in reducing the event of hypoxemia.
evaluate the Efficacy of high flow nasal oxygen as a weaning strategy in mechanically ventilated patients with respiratory failure.
Purpose of Study: Apnoea of Prematurity (AOP) is common, affecting the majority of infants born <34 weeks gestational age (GA). Apnea is accompanied by intermittent hypoxia (IH), which contributes to multiple pathologies, including retinopathy of prematurity (ROP), sympathetic ganglia injury, impaired pancreatic islet cell and bone development, and neurodevelopmental disabilities. Standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and caffeine therapy. The objective of this device is to provide an adjunct to current AoP treatment to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements facilitate breathing. Methods Used: Premature infants (27+6 - 34+6 weeks GA) with clinical confirmed weeks with diagnosis of Apnoea of Prematurity. Caffeine therapy was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in a 6 hour ON/OFF sequence for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected.
In clinical practice discrepancies between overnight SpO2 recordings performed by 2 devices used simultaneously are regularly observed. However, this has not been systematically studied or quantified. It is therefore important to determine if these discrepancies are anecdotic, or frequent, and to what extent this may affect decisions in clinical practice such as implementing (or withdrawing) oxygen in subjects under noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP), or adjusting NIV settings.
Perinatal asphyxia is a major cause of hypoxic Ischemic encephalopathy (HIE), perinatal death and long term neurodisability. This can be devastating for the individual and their family; the healthcare and litigation costs notwithstanding. In recent years have attempted to quantify the effect, and wider impact of intrapartum compromise, as well as the underlying mechanisms for it. After a poor outcome related to intrapartum care parents and healthcare practitioners often strive to understand whether the event could have been predicted and/or prevented. This can be difficult to answer, at least partly related to the heterogeneous fetal response to perinatal asphyxia. Mothers and the maternity service are increasingly encouraged to personalize care and their choices around the birth process, however the information required to guide these choices is most often missing. This makes it difficult for women and professionals to make an informed choice about their care, including the safest mode of birth for them and their baby. Aim of the study: Identifying antenatal and intrapartum risk factors associated with neonatal hypoxic ischemic encephalopathy.
