Mild hypothermia has been shown to improve neurological outcome and reduce mortality following out of hospital cardiac arrest. In animal models the application of hypothermia with induced coronary occlusion has demonstrated a reduction in infarct size. Consequently, hypothermia has been proposed as a treatment, in addition to Primary Percutaneous Coronary Intervention (PPCI) for ST segment elevation myocardial infarction (STEMI). However, there is incomplete understanding of the mechanism and magnitude of the protective effect of hypothermia on the myocardium, and limited outcome data...

Although previous research has demonstrated that traumatic brain injury (TBI) accelerates the proliferation of neural stem cells in dentate gyrus of the hippocampus, most of these newborn cells undergo apoptosis in a traumatic microenvironment. Thus, promoting the long-term survival of newborn cells during neurogenesis is a compelling goal for the treatment of TBI. In this study, we investigated whether mild hypothermia (MHT) therapy, which mitigates the multiple secondary injury cascades of TBI, enhances the survival of newborn cells...

Bloodletting at Jing points has been used to treat coma in traditional Chinese medicine. Mild induced hypothermia has also been shown to have neuroprotective effects. However, the therapeutic effects of bloodletting at Jing points and mild induced hypothermia alone are limited. Therefore, we investigated whether combined treatment might have clinical effectiveness for the treatment of acute severe traumatic brain injury. Using a rat model of traumatic brain injury, combined treatment substantially alleviated cerebral edema and blood-brain barrier dysfunction...

Although therapeutic hypothermia is an effective treatment for post-resuscitation brain injury after cardiac arrest (CA), the underlying mechanism remains unclear. Vacuolar H(+)-ATPase (V-ATPase) plays a key role in cellular adaption to a hypoxic environment. This study sought to evaluate the effect of mild hypothermia on V-ATPase and its involvement in neuroprotection after CA. Male Sprague-Dawley rats were subjected to a 6-min CA, resuscitated successfully, and then assigned to either the normothermia (NT) group or the hypothermia (HT) group...

Mild physical hypothermia after stroke has been associated with positive outcomes. Despite the well-studied beneficial effects of hypothermia in the treatment of stroke, lack of precise temperature control, intolerance for the patient, and immunosuppression are some of the reasons which limit its clinical translation. Pharmacologically induced hypothermia has been explored as a possible treatment option following stroke in animal models. Currently, there are eight classes of pharmacological agents/agonists with hypothermic effects affecting a multitude of systems including cannabinoid, opioid, transient receptor potential vanilloid 1 (TRPV1), neurotensin, thyroxine derivatives, dopamine, gas, and adenosine derivatives...

BACKGROUND AND PURPOSE: Therapeutic hypothermia is a promising strategy for treatment of acute stroke. Clinical translation of therapeutic hypothermia, however, has been hindered because of the lack of efficiency and adverse effects. We sought to enhance the clinical potential of therapeutic hypothermia by combining physical cooling (PC) with pharmacologically induced hypothermia after ischemic stroke. METHODS: Wistar rats were subjected to 90-minute middle cerebral artery occlusion by insertion of an intraluminal filament...

BACKGROUND: Patients admitted to the hospital after primarily successful cardiopulmonary resuscitation (CPR) are at a very high risk for neurologic deficits and death. Targeted temperature management (TTM) for mild therapeutic hypothermia has been shown to improve survival compared to standard treatment. Acute cardiovascular events, such as myocardial infarction (MI), are a major cause for cardiac arrest (CA) in patients who undergo CPR. Recent findings have demonstrated the importance and impact of the leukocyte response following acute MI...

UNLABELLED:  Abstract  PURPOSE: several therapeutic options are used in emergency situations, when heart and/or lung functions acutely fail. Because of the poor results of conventional treatments, the use of an extra-corporeal life support (ECLS) systems able to completely assume the heart and lung functions in emergency situations is becoming a viable alternative. We have developed a unique ECLS system for patients needing extended respiratory and/or circulatory support and controlled hypothermia...

The presence of a pathologic mass in the right ventricle (RV) may lead to hemodynamic consequences and to a life-threatening incident of pulmonary embolism. The diagnosis of an unstable thrombus in the right heart chamber usually necessitates intensive treatment to dissolve or remove the pathology. We present a report of an unusual complication of severe ketoacidosis: thrombus in the right ventricle, removed from the tricuspid valve (TV) apparatus. A four-year-old boy was diagnosed with diabetes mellitus (DM) type I de novo...

The use of mild therapeutic hypothermia (MTH) in adult patients remaining in a coma following cardiac arrest, regardless of its mechanism and location, is recommended by the European Resuscitation Council. The study presents a case of a 52-year-old man in whom MTH was used following successfully resuscitated out-of- hospital sudden cardiac arrest caused by ventricular fibrillation. On the basis of this case it was indicated that the use of low temperatures may be an effective method of neuroprotective treatment since such activity is compatible with later observed great possibility of the brain to compensate and with the maintenance of brain plasticity which is crucial for neuropsychological rehabilitation...

In the last fifteen years mild therapeutic hypothermia became an accepted and widespread therapeutic method in the treatment of successfully resuscitated patients due to sudden cardiac death. Based on the available evidence therapeutic hypothermia is part of the resuscitation guidelines, however, many aspects of its therapeutic use are based on empirical facts. In particular, the subjects of intense debate are the ideal target temperature and the benefit of hypothermia in patients found with non-shockable rhythm...

Pediatric cardiac arrest (CA) often leads to poor neurologic outcomes, including deficits in learning and memory. The only approved treatment for CA is therapeutic hypothermia, although its utility in the pediatric population remains unclear. This study analyzed the effect of mild therapeutic hypothermia after CA in juvenile mice on hippocampal neuronal injury and the cellular model of learning and memory, termed long-term potentiation (LTP). Juvenile mice were subjected to cardiac arrest and cardiopulmonary resuscitation (CA/CPR) followed by normothermia (37°C) and hypothermia (30°C, 32°C)...
