To investigate the different effects of mild hypothermia on pathological and physiological stress conditions in piglets, 30 pigs were randomized into four groups: cardiac arrest and mild hypothermia (CA-MH group), cardiac arrest and normothermia (CA-NH group), non-CA-MH (NCA-MH group), and a sham operation. The same hypothermia intervention was implemented in both CA-MH and NCA-MH groups. The CA-NH group did not undergo therapeutic hypothermia after resuscitation. The hemodynamic parameters were recorded. Cerebral metabolism variables and neurotransmitters in the extracellular fluid were collected through microdialysis tubes...

Targeted temperature management (TTM) is recommended as a standard of care for postcardiac arrest patients. Current TTM methods have significant limitations to be used in an ambulatory setting. We investigated the efficacy and safety of a novel noninvasive transnasal evaporative cooling device (CoolStat™). Eleven Yorkshire pigs underwent hypothermia therapy using the CoolStat device. CoolStat induces evaporative cooling by blowing dehumidified ambient air over the nasal turbinates in a unidirectional fashion...

Therapeutic hypothermia following neonatal encephalopathy is neuroprotective. However, approximately one in two cooled infants still die or develop permanent neurological impairments. Further understanding of variables associated with the effectiveness of cooling is important to improve the therapeutic regimen. To identify clinical factors associated with short-term outcomes of cooled infants, clinical data of 509 cooled infants registered to the Baby Cooling Registry of Japan between 2012 and 2014 were evaluated...

Targeted temperature management (TTM), or therapeutic hypothermia, is one of the most potent neuroprotective approaches after ischemic and traumatic brain injuries. TTM has been applied clinically with various methods, but effective achievement and maintenance of the target temperature remain challenging. Furthermore, timing of cooling and target body and brain temperature to optimize effectiveness for neuroprotection and to minimize side effects are yet to be standardized. Focal brain cooling is a potential strategy to minimize adverse effects of systemic TTM...

For better care of postcardiac arrest patients, objective serial assessments of brain injury severity are needed. We hypothesized that monitoring of cerebral energy metabolism based on arterio-jugular (AJ) differences of metabolites will provide serial details of brain injury and information about neurologic outcomes in patients. Measurements of lactate and glucose in addition to blood gas analyses were done every 6 hours from the radial artery and jugular bulb in postcardiac arrest patients throughout targeted temperature management (TTM)...

In patients with aneurysmal subarachnoid hemorrhage (aSAH), increased brain extracellular interleukin (IL)-6 levels measured by cerebral microdialysis (CMD) were associated with disease severity, early brain injury, delayed cerebral infarction, and axonal injury. In this study, we analyzed brain extracellular IL-6 levels of aSAH patients following parenteral diclofenac. Twenty-four mechanically ventilated poor-grade aSAH patients were included. Changes in cerebral metabolism, brain/body temperature, and CMD-IL-6 levels following intravenous diclofenac infusion (DCF; 75 mg diluted in 100 cc normal saline) were retrospectively analyzed from prospectively collected bedside data (at 1 hour before DCF = baseline; and at 2, 4, and 8 hours after DCF)...

Chipmunk as a food-storing hibernator naturally undergoes hibernation that is linked to great changes in systemic physiology and could protect the central nervous system during drastically reduced cerebral blood flow and low temperature in hibernation. Deep hypothermic circulatory arrest (DHCA) is associated with neurological dysfunction. We aim to test whether the euthermic chipmunk is resistant to injury from DHCA. Sprague-Dawley (SD) rats were used in a positive control. Ten euthermic chipmunks and 10 rats were subjected to 60-minute DHCA...

Ischemia-reperfusion (I/R)-induced oxidative stress is one of the main mechanisms of tissue injury after cardiac arrest (CA). A decrease in antioxidant defenses may contribute to I/R injury. The present study aims to investigate the influence of mild therapeutic hypothermia (MTH) on levels of nonenzymatic antioxidants after CA. We investigated antioxidant levels at 6, 12, 36, and 72 hours after CA in central venous blood samples of patients admitted to intensive care. The sample consisted of 31 patients under controlled normothermia (36°C) and 11 patients treated with 24 hours of MTH (33°C)...

Targeted temperature management (therapeutic hypothermia) is a treatment method used to prevent potential complications that can develop in relation to the increased temperature in the brain as a result of cardiac arrest. Due to costs and various health policies there is no comprehensive study in the world that has been able to guide the relevant literature on therapeutic hypothermia. We have presented a 25-year-old female patient in our study who developed cardiac arrest after the administration of propofol for sedation before undergoing a diagnostic upper gastroscopy procedure and received a successful therapeutic hypothermia therapy following a resuscitation of 19 minutes...

Cerebral arterial gas embolism (CAGE) shows various manifestations according to the quantity of gas and the brain areas affected. The symptoms range from minor motor weakness, headache, and confusion to disorientation, convulsions, hemiparesis, unconsciousness, and coma. A 46-year-old man was transferred to our emergency department due to altered sensorium. Immediately after a controlled ascent from 33 m of seawater, he complained of shortness of breath and rigid extremities, lapsing into unconsciousness...

Hyperpyrexia is a well-documented adverse effect of 3,4-methylenedioxymethamphetamine (MDMA) and is associated with a poor prognosis. There are currently limited published records of patients surviving a pyrexia of or greater than 43°C after MDMA intake. Rapid cooling and multiorgan support in an intensive care setting may offer patients the best chance of recovery. We present the case of a 16-year-old male who was admitted to our tertiary, adult intensive care unit (ICU) for unrecordable pyrexia (>43°C) after reported ecstasy intake...

Mild therapeutic hypothermia (MTH 33°C) post out-of-hospital cardiac arrest (OHCA) is widely accepted as standard of care. However, uncertainty remains around the dose and therapy duration. OHCA patients are usually kept sedated±paralyzed and ventilated for the first 24-36 hours, which allows for targeted temperature management, but makes neurological prognostication challenging. The aim of this study is to investigate the feasibility and safety of assessing the unconscious OHCA patient after 12 hours for early waking/extubation while continuing to provide MTH for 24 hours, and fever prevention for 72 hours by using an intravenous temperature management (IVTM) system and established conscious MTH anti-shiver regimens...

Brain herniation is most often the result of severe brain swelling and can rapidly lead to death or brain death. We retrospectively identified radiologic indicators to evaluate the effects of targeted temperature management (TTM) on the extent of cerebral edema and determine the cutoff values that best predict TTM outcomes in patients with large hemispheric infarction. We retrospectively reviewed brain computed tomography (CT) scans of 21 patients with large hemispheric infarctions, who were treated with TTM...

Deep and profound hypothermia is successfully practiced in the prevention of ischemic stroke consequences and aortic arch cardiac surgery accompanied by reduction of cerebral circulation. Hypothermia is a current neuroprotection standard in hypoxic/ischemic encephalopathy. Drug-hypothermia administration is proposed as a new approach in pharmacotherapy for neonatal seizures. Also, hypothermia is useful as neuroprotective approach in long-term interplanetary space missions. We recently revealed gradual dynamics of hypothermia-induced decrease in transporter-mediated release and uptake of L-[14 C]glutamate in presynaptic rat brain nerve terminals (synaptosomes), thereby confirming potent unspecific neuroprotective effect of hypothermia...

Therapeutic hypothermia is an established treatment in patients resuscitated from cardiac arrest. It is usually well-tolerated circulatory, but hypothermia negatively effects myocardial contraction and relaxation velocities and increases diastolic filling restrictions. A significant proportion of resuscitated patients are treated with long-acting beta-receptor blocking agents' prearrest, but the combined effects of hypothermia and beta-blockade on left ventricle (LV) function are not previously investigated...
