Accidental hypothermia could be listed as an 'orphan disease,' since mild hypothermia is common but has no severe medical consequences, whereas severe hypothermia is rare and life-threatening. In order to increase our knowledge, find new outcome predictors, and propose better guidelines for the treatment of deep accidental hypothermia victims, we created the International Hypothermia Registry (IHR: https://www.hypothermia-registry.org), which will allow us to gather a large number of cases in order to achie...
Perioperative hypothermia decreases nutrient and oxygen delivery to tissues and, in adult studies, increases the risk of infectious complications (ICs). Gastroschisis (GS) places newborns at risk for hypothermia by nature of exposed viscera and excessive heat loss. Although hypothermia is a known cause of mortality in GS, the rate of ICs in this at-risk cohort has not yet been delineated.
We provide the first complete biophysical study of surfactant by captive bubble surfactometry from a neonate with meconium-stained amniotic fluid under controlled whole body hypothermia. Surfactant function improves after 48 hours of hypothermia, as surfactant cholesterol decreases. These findings partially explain positive effect of hypothermia on respiratory outcomes during meconium aspiration syndrome. A larger study including several neonates with or without lung disease is being conducted to better def...
Treatment with therapeutic hypothermia has challenged the use of amplitude-integrated electroencephalography in predicting outcomes after perinatal asphyxia. In this study, we assessed the feasibility and gain of somatosensory evoked potentials (SEP) during hypothermia.
Patients with severe accidental hypothermia require active rewarming. External rewarming may not be successful in severe hypothermia, and use of invasive techniques is limited to regional centers and is associated with vascular access site and other complications. We present a patient with severe accidental hypothermia who was successfuly rewarmed using a novel esophageal heat transfer device. A 55-year-old male (175 cm, 71 kg) was admitted with the first recorded temperature 23.3°C. Rewarming using re...
Clinical studies measuring cerebral blood flow in infants during deep hypothermia have demonstrated diminished cerebrovascular pressure autoregulation. The coexistence of hypotension in these cohorts confounds the conclusion that deep hypothermia impairs cerebrovascular pressure autoregulation.

Mild therapeutic hypothermia is argued being beneficial for outcome after cardiac arrest.
The benefit of whole-body hypothermia in preventing ischemic injury during cardiac surgical operations is well documented. However, application of hypothermia during in vivo total artificial heart implantation has not become widespread because of limited understanding of the proper techniques and restrictions implied by constitutional and physiological characteristics specific to each animal model. Similarly, the literature on hypothermic set-up in total artificial heart implantation has also been limited. ...
Redox regulation has recently been recognized as an important factor in acute illnesses as well as in chronic diseases. It has also become a target for neuroprotection in acute intensive care. Despite its well-known therapeutic effects, therapeutic hypothermia has recently been re-evaluated for its potential use in emergency and critical care medicine. Hypothermia is an undesirable physiological condition that can increase oxidative stress and decrease anti-oxidative potency. However, many studies have show...
The selective α2-adrenoreceptor agonist dexmedetomidine has shown neuroprotective, analgesic, anti-inflammatory, and sympatholytic properties that may be beneficial in neonatal encephalopathy (NE). As therapeutic hypothermia is only partially effective, adjunct therapies are needed to optimize outcomes. The aim was to assess whether hypothermia + dexmedetomidine treatment augments neuroprotection compared to routine treatment (hypothermia + fentanyl sedation) in a piglet model of NE using magnetic resonanc...
Prior studies suggest hypothermia may be beneficial in acute respiratory distress syndrome, but cooling causes shivering and increases metabolism. The objective of this study was to assess the feasibility of performing a randomized clinical trial of hypothermia in patients with acute respiratory distress syndrome receiving treatment with neuromuscular blockade because they cannot shiver.
Mild hypothermia improves survival and neurological recovery after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). However, the mechanism underlying this phenomenon is not fully elucidated. The aim of this study was to determine whether mild hypothermia alleviates early blood-brain barrier (BBB) disruption. We investigated the effects of mild hypothermia on neurologic outcome, survival rate, brain water content, BBB permeability and changes in tight junctions (TJs) and adherens junctions (AJs) ...
The postmortem diagnosis of hypothermia remains problematic even in the era of molecular and digital diagnostic advances. Gross hemorrhages in iliopsoas muscles have been regarded as a helpful diagnostic sign in hypothermia fatalities; nevertheless, they have received marginal attention since their original description. The present study attempts to fill that void by examining occurrence, localization, and diagnostic significance of the bleeding into the core muscles as evidence of death due to hypothermia ...
The protective effects of induced or even accidental hypothermia on the human body are widespread with several medical uses currently under active research. In vitro experiments using human cell lines have shown hypothermia provides a radioprotective effect that becomes more pronounced at large, single-fraction doses common to stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS) treatments. This work describes the development of a system to evaluate local hypothermia for a radioprotive ...
Hypothermia reduces reperfusion injury and infarct size in animal models of acute myocardial infarction if started before reperfusion. Human studies have not confirmed benefit, probably due to insufficient myocardial cooling and adverse systemic effects. This study assessed safety and feasibility of a novel method for selective, sensor- monitored intracoronary hypothermia.
During the last decade target temperature management has become an integral part of postresuscitation care. Within recent years there was a strong debate about the optimal target temperature, which might have effects on the preclinical induction of hypothermia. The present investigation focuses on the use of mild therapeutic hypothermia by emergency services in the state of Baden-Württemberg (Germany) and compares it to results of a prior study in 2008.
The reliability of somatosensory evoked potentials (SSEPs) in predicting outcome in comatose survivors of cardiac arrest treated with therapeutic hypothermia (TH) has been questioned. We investigated whether the absence of cortical (N20) responses was a reliable predictor of a nonawakening in the setting of TH.
Global cerebral ischemia is a cause of poor prognosis after resuscitation from cardiac arrest. Various attempts have been made to minimize global cerebral ischemia but none been more effective than mild hypothermia induction. A few studies have shown the effect of mesenchymal stem cells on global cerebral ischemia, but no studies have compared this effect with mild hypothermia or assessed any possible interaction. We aimed to show the effect of mesenchymal stem cells on delayed neuronal death after global c...
Accidental hypothermia is an unintentional drop in core temperature to 35°C or below. Core temperature is best measured by esophageal probe. If core temperature cannot be measured, the degree should be estimated using clinical signs. Treatment is to protect from further heat loss, minimize afterdrop, and prevent cardiovascular collapse during rescue and resuscitation. The patient should be handled gently, kept horizontal, insulated, and actively rewarmed. Active rewarming is also beneficial in mild hypothe...
Transcatheter Aortic Valve Replacement (TAVR) procedures at our institution were complicated by perioperative hypothermia despite use of the standard of care forced-air convective warming device (the BairHugger, Augustine Medical Inc, Eden Prairie, MN, USA). To remedy this problem, we initiated a quality improvement process that investigated the use of a conductive warm water-circulating device (the Allon ThermoWrap, Menen Medical Corporation, Trevose, PA, USA), and hypothesized that it would decrease the i...
The present study was undertaken to investigate the influence of hypothermia on endothelium-independent vascular smooth muscle contractility and to determine the mechanism underlying the relaxation. Denuded aortic rings from male rats were used and isometric contractions were recorded and combined with molecular experiments. Hypothermia significantly inhibited fluoride-, thromboxane A₂-, phenylephrine-, and phorbol ester-induced vascular contractions regardless of endothelial nitric oxide synthesis, sugge...
Occlusive body wrap using polyethylene plastic applied immediately after birth had been shown to reduce hypothermia among preterm infants. Various adjunct methods have been studied in an attempt to further reduce the incidence of hypothermia. This study was conducted to determine whether polyethylene cap is more effective than cotton cap as an adjunct to polyethylene occlusive body wrap in reducing hypothermia among preterm infants.
Hypothermia is an important complication in joint arthroplasty. Commonly, forced air warming (FAW) devices are used intraoperatively to maintain body temperature in patients undergoing surgery. However, it is believed that these convective warming systems could increase the risk of deep surgical site infections due to disruption of unidirectional downward laminar airflow. Conductive warming devices have no noticeable effect on ventilation airflow. Nevertheless, the effectiveness of the self-warming (SW) bla...
