It is important for physicians treating children to be aware of unique presentation that require expertise and knowledge. Two areas of importance when caring for traumatized children are Thermal Burn Injuries, and Hypothermia. Burns commonly result in morbidity in children; as such, the appropriate identification of the severity of the burn and appropriate management are integral to minimize the complications of burns during the acute phase. Attention to proper fluid management is paramount. Knowledge of types of solutions to use during Burn treatment is important...

BACKGROUND: Extra-corporeal life support (ECLS) is a life-saving intervention for patients with hypothermia induced cardiac arrest or severe cardiovascular instability. However, its application is highly variable due to a paucity of data in the literature to guide practice. Current guidelines and recommendations are based on expert opinion, single case reports, and small case series. Combining all of the published data in a patient-level analysis can provide a robust assessment of the influence of patient characteristics on survival with ECLS...

AIMS: Currently, the decision to initiate extracorporeal life support for patients who suffer cardiac arrest due to accidental hypothermia is essentially based on serum potassium level. Our goal was to build a prediction score in order to determine the probability of survival following rewarming of hypothermic arrested patients based on several covariates available at admission. METHODS: We included consecutive hypothermic arrested patients who underwent rewarming with extracorporeal life support...

Rewarming following accidental hypothermia is associated with circulatory collapse due primarily to impaired cardiac contractile (systolic) function. Previously, we found that reduced myofilament Ca2+ sensitivity underlies hypothermia/rewarming (H/R)-induced cardiac contractile dysfunction. This reduced Ca2+ sensitivity is associated with troponin I (cTnI) phosphorylation. We hypothesize that H/R induces reactive oxygen species (ROS) formation in cardiomyocytes, which leads to cTnI phosphorylation and reduced myofilament Ca2+ sensitivity...

Rewarming from accidental hypothermia is associated with cardiovascular dysfunction that complicates rewarming and contributes to a high mortality rate. We investigated autonomic cardiovascular control, as well as the separate effects of cooling, hypothermia, and rewarming on hemodynamic function, aiming to provide knowledge of the pathophysiology causing such complications in these patients. A rat model designed for circulatory studies during cooling, hypothermia (15°C), and rewarming was used. Spectral analysis of diastolic arterial pressure and heart rate allowed assessment of the autonomic nervous system...

Extensive evidence exists on the association between hypothermia and increased morbidity and mortality in trauma patients. Gaps in practice related to temperature assessment have been identified in literature, along with limited personnel knowledge regarding management of patients with accidental hypothermia. An interdisciplinary team identified gaps in practice in our institution regarding temperature assessment and documentation of rewarming and initiated an evidence-based practice project to change practice at our institution...

PURPOSE: Patients with multiple injuries are particularly susceptible to accidental hypothermia which is correlated with an increased risk of post-traumatic complications and mortality; however, its impact on neurological outcome in cases where there is concomitant traumatic brain injury is underexplored. METHODS: We analyzed severely injured patients (ISS ≥ 16) including a moderate-to-severe traumatic brain injury (AISHead  ≥ 3). The primary endpoint was objective neurological recovery, expressed as Glasgow Outcome Scale (GOS) score at time of discharge...

Polish Medical Air Rescue is tasked to deal with the most serious incidents associated with life threatening situations, in multiple circumstances. As a consequence, medical personnel have to meet high standards of education and show a continuous theoretical and practical development of the skills which are necessary during medical treatment. Thanks to the introduction of ECMO treatment for accidental hypothermia patients, new clinical and operational possibilities have arisen, so more patients can be saved with a very good neurological outcome...

BACKGROUND: Accidental hypothermia concerns a body core temperature of less than 35°C without a primary defect in the thermoregulatory system. It is a serious threat to prehospital patients and especially injured patients, since it can induce a vicious cycle of the synergistic effects of hypothermia, acidosis and coagulopathy; referred to as the trauma triad of death. To prevent or manage deterioration of a cold patient, treatment of hypothermia should ideally begin prehospital. Little effort has been made to integrate existent literature about prehospital temperature management...

BACKGROUND: The elderly are vulnerable to cold and prone to accidental hypothermia, both because of environmental and endogenous factors. The incidence of severe accidental hypothermia among the elderly is poorly described, but many cases probably go unrecorded. Going through literature one finds few publications on severe hypothermia among the elderly, and, to our knowledge, nothing about extracorporeal re-warming of geriatric hypothermia victims. CASE PRESENTATION: We present a case were a 95 year-old man with severe accidental hypothermia and circulatory arrest was brought to our hospital under on-going CPR, and was successfully resuscitated with extracorporeal circulation...

BACKGROUND: Application of appropriate method of rewarming is the key issue in the management of hypothermia. Severely hypothermic, life-threatened patients require advanced extracorporeal rewarming. Such procedure is not free of possible complications, yet, if the qualification for extracorporeal rewarming is correct, it guarantees restoration of hemodynamic stability, and what is the most important, leads to full neurologic recovery, even with long resuscitation times. THE AIM: The summary of complications observed during extracorporeal rewarming with ECMO in severely hypothermic patients and analysis of their prevalence in managed group...

AIM: The aim of the present study was to assess the ability of the biomarkers neuron-specific enolase (NSE) and S100 calcium-binding protein b (S100b) to predict mortality and poor neurologic outcome after 30days in patients admitted with severe accidental hypothermia. METHODS: Consecutive patients with severe accidental hypothermia, defined as a core temperature <32°C, were included. Patients were treated with active rewarming and/or extracorporeal life support (ECLS) using extra corporeal circulation (ECC) and/or extra corporeal membrane oxygenation (ECMO)...

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 renal replacement therapy circuit was unsuccessful because of severe hypotension...

RATIONALE: Despite guidelines advising passive rewarming for mild accidental hypothermia (AH), patients are frequently admitted to intensive care unit (ICU) for active rewarming using a forced-air warming device. We implemented a new policy at our institution aimed at safely reducing ICU admissions for AH. We analyzed our practice pre- and post-policy intervention and compared our experiences with acute care hospitals in Connecticut. METHODS: A retrospective chart review was performed on 203 participants with AH identified by primary and secondary discharge codes...

BACKGROUND: Acetaminophen is an over-the-counter drug used to treat pain and fever, but it has also been shown to reduce core temperature (Tc ) in the absence of fever. However, this side effect is not well examined in humans, and it is unknown if the hypothermic response to acetaminophen is exacerbated with cold exposure. OBJECTIVE: To address this question, we mapped the thermoregulatory responses to acetaminophen and placebo administration during exposure to acute cold (10 °C) and thermal neutrality (25 °C)...

BACKGROUND: Accidental hypothermia with cardiac arrest represents a challenge for pre-hospital rescuers as well as in-hospital staff. For pre-hospital personnel, the main focus is to get the patient to the correct destination without unnecessary delay. For in-hospital personnel early information is vital to assess the possibility for resuscitation with extracorporeal re-warming. The challenge is augmented when rescuers must cross national borders to reach and/or deliver the patients. We present a case where three adolescent boys suffered severe hypothermia after a canoeing accident in Sweden...

Sixty pullets, aged 17 weeks, were presented when presumed to be 'dead' after being exposed to wet-cold weather transportation. The birds appeared unconscious and their feathers were soaking wet, and with a body rigid and cold to touch. The aim of the study was to resuscitate the hypothermic pullets. Blood samples were obtained and core body temperature recorded before and after rewarming. The birds were resuscitated using active external rewarming technique. Blood samples revealed significant (P < 0...
