Active clinical trials for "Hypothermia"

Due to the rising incidence of renal failure and the improvement of organ transplantation technology, the shortage of donor organs has become one of the main problems limiting the development of kidney transplantation. Marginal donor is one of the important ways to extend the donor pool. Normothermic mechanical perfusion (NMP) is a new generation of organ preservation technology, which can maintain the blood supply and at the same time evaluate the marginal kidney function during the organ preservation. However, the clinical effect has not been proved. Hypothermic Machine Perfusion (HMP) is the mainstream organ perfusion technology. This study aims to compare the effectiveness of NMP with the HMP.

The purpose of the research is to determine if the Hepatitis B vaccine after birth provides enough protection after cooling for Hypoxic Ischemic Encephalopathy (HIE). To do this, Hepatitis B titers (blood sample) would be taken before, during, and after administering of the Hepatitis B vaccine series to measure efficacy of the vaccine.

The TIME study is a randomized, controlled trial to evaluate impact on early measures of neurodevelopment and the safety profile of therapeutic hypothermia in term neonates with Mild Hypoxic-Ischemic Encephalopathy who are < 6 hours of age. Neurodevelopmental outcome will be assessed at 12-14 months of age. The study will enroll 68 neonates randomized to therapeutic hypothermia or normothermia across 5 centers in California.

The primary objective of this study is to determine the feasibility and safety of receiving intravascular hypothermia treatment for patients experiencing endovascular treatment after acute ischemic stroke(AIS) due to a large vessel occlusion.

This study aims to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Based on this study the investigators aimed to explore the effect of perioperative hypothermia on postoperative pain.

The aim of our study is to evaluate the feasibility of applying transcutaneous CO2 monitoring (tcPCO2) in neonates receiving therapeutic hypothermia and to quantify the agreement between tcPCO2 and PCO2 in this population with or without respiratory support. Although, transcutaneous measurement of CO2 tension is the most commonly used non-invasive CO2 monitoring system in neonatal intensive care, to date tcPCO2 technique has not been evaluated systematically or used routinely in the intensive care of infants with neonatal encephalopathy receiving hypothermia treatment.

Perinatal hypoxia in the form of hypoxic-ischaemic encephalopathy (HIE) is a frequent cause of cerebral impairment in neonates. HIE occurs in 3 to 5 of 1000 neonates in developed countries and is significantly higher in developing countries at 25 of 1000 neonates. Despite developments in medicine, increasing understanding of HIE pathophysiology and progress in neonatal intensive care as well as treatment of moderate or severe perinatal asphyxia, HIE continues to be associated with significant mortality and late neurological sequelae. Episodes of ischaemia-hypoxia in the perinatal period as well as the changes in the redistribution of blood may lead to decreased perfusion and ischaemia of the cardiac muscle. Additionally, there is a negative impact from the reduced contractility of the cardiac muscle secondary to acidosis and hypoxia. Therapeutic hypothermia (TH) improves the late effects in moderate and severe cases of hypoxia-ischaemia encephalopathy (HIE). The direct impact of TH on the cardiovascular system includes moderate bradycardia, increased pulmonary vascular resistance (PVR), inferior filling of the left ventricle (LV) and LV stroke volume. The above-mentioned consequences of TH and episodes of HI in the perinatal period are therefore exacerbation of respiratory and circulatory failure. The impact of the warming phase on the cardiovascular system is not well researched and currently few data has been published on this topic. Physiologically, warming increases heart rate, improves cardiac output and increases systemic pressure. The effect of TH and the warming phase on the cardiovascular values has a decisive impact on the metabolism of drugs, including vasopressors / inotropics, which in turn affects the choice of medication and fluid therapy

The aim of this investigation is to provide guidance for assessing the influence of wet clothing, and its drying time, on body temperature responses during cold air exposure. Twelve healthy and fit adults (men and women aged 18-49) will complete this study. Four cold air exposures (41°F, 180 min) will be randomly conducted, each while wearing a different clothing ensemble that has been saturated by water. During each cold air exposure, you will be asked to rest for 60 min and perform weighted (38.5lbs) treadmill walking for up to 120 min.

A phase 1 study investigating the tolerability and pharmacokinetics of caffeine citrate in neonates with hypoxic ischemic encephalopathy receiving therapeutic hypothermia. This study is an essential first step to develop caffeine as a kidney protective medication in this in this vulnerable group of newborns.

The purpose of this study is to improve the ability of the investigators to monitor brain health in newborn babies at risk of brain injuries. The researchers will be using an investigational system of devices to non-invasively (that, is, without penetrating the skin), measure the amount of oxygen going to and being used by the brain. They will be taking some bedside research measurements during the babies' stay at the hospital. With these measurements, the intention is to study the role of oxygen in brain injury and test the efficacy of the research device and its potential as a permanent bedside diagnostic device.
