: Therapeutic temperature control has been widely used during the last decade to improve clinical outcomes. We conducted this retrospective observational study to compare traditional cooling with endovascular cooling in post-cardiac arrest comatose survivors and to compare results with current guidelines. PATIENTS AND METHODS: All patients admitted to our ICU for cardiac arrest and for whom temperature control was performed were included. Traditional cooling included cold infusions, ice packs and cooling blankets...

Our purpose was to analyze evidence related to timing of cooling from studies of targeted temperature management (TTM) after return of spontaneous circulation (ROSC) after cardiac arrest and to recommend directions for future therapy optimization. We conducted a preliminary review of studies of both animals and patients treated with post-ROSC TTM and hypothesized that a more rapid cooling strategy in the absence of volume-adding cold infusions would provide improved outcomes in comparison with slower cooling...

Therapeutic hypothermia is used in select patients after out-of-hospital cardiac arrest (OHCA) to improve neurologic outcome. Rebound hyperthermia (RH) is commonly observed post-treatment. Previous studies analyzing the association of RH with clinical outcome have reported conflicting results. The purpose of this study is to examine the impact of RH after completion of therapeutic hypothermia in patients postcardiac arrest. We analyzed a retrospective cohort from our institution. All adults who underwent therapeutic hypothermia post-OHCA were divided into two cohorts depending on the presence/absence of fever (T > 38°C) within 24 hours of completing hypothermia protocol...

Targeted temperature management (TTM) has been shown to reduce mortality and improve neurological outcomes in out-of-hospital cardiac arrest (CA) patients and in neonates with hypoxic-ischemic encephalopathy (HIE). TTM has also been associated with adverse drug events in the critically ill patient due to its effect on drug pharmacokinetics (PKs) and pharmacodynamics (PDs). We aim to evaluate the current literature on the effect of TTM on drug PKs and PDs following CA. MEDLINE/PubMed databases were searched for publications, which include the MeSH terms hypothermia, drug metabolism, drug transport, P450, critical care, cardiac arrest, hypoxic-ischemic encephalopathy, pharmacokinetics, and pharmacodynamics between July 2006 and October 2015...

AIM: Post-cardiac arrest hypothermic-targeted temperature management (HTTM) improves outcomes in preclinical cardiac arrest studies. However, inadequate understanding of the mechanisms and therapeutic windows remains a barrier to optimization. We tested the hypothesis that combined intra- and post-cardiac arrest HTTM provides a synergistic outcome benefit compared to either strategy alone. METHODS: Rats subjected to 8-min asphyxial cardiac arrest were block randomized to 4 treatment groups (n=12/group): NTTM) normothermic-targeted temperature management; 1-24 HTTM) HTTM initiated 1h post-ROSC and maintained for 24h; Intra-1 HTTM) HTTM initiated at CPR onset and maintained for 1h; and Intra-24 HTTM) HTTM initiated at CPR onset and maintained for 24h...

Malignant hyperthermia (MH) is a rare and potentially life threatening fatal complication of anaesthesia. We present a 2-year-old boy with late onset MH after colon interposition to replace the oesophagus under sevoflurane anaesthesia. The patient was treated with intravenous dantrolene sodium as well as cooling and controlled ventilation. Despite treatment, the patient developed cardiopulmonary arrest at 21 hours after the operation and died. It should be kept in mind that post-operative MH may develop during these types of operations with ischaemia-reperfusion injuries...

Ultra-fast cooling for mild therapeutic hypothermia (MTH) has several potential applications, including prevention of post-cardiac arrest syndrome. Ultra-fast MTH by total liquid ventilation (TLV) entails the sudden filling of the lungs with a cold perfluorocarbon liquid and its subsequent use to perform TLV. The present physiological study was aimed at assessing whether pulmonary and systemic hemodynamics as well as lung mechanics are significantly altered during this procedure. Pulmonary and systemic arterial pressures, cardiac output as well as airway resistance and respiratory system compliance were measured during ultra-fast MTH by TLV followed by rewarming and normothermia in six healthy juvenile lambs...

Cellular damage after reperfusion of ischaemic tissue is defined as ischaemia-reperfusion injury (IRI). Hypothermia is able to decrease oxygen consumption, preventing a rapid loss of mitochondrial activity. However, even though cooling can help to decrease the deleterious effects of ischaemia, the consequences are not exclusively beneficial, such that hypothermic storage is a compromise between benefits and harm. The present review details the relationship between renal IRI and hypothermia, describing the pathophysiology of IRI and hypothermic protection through experimental evidence...

INTRODUCTION: Target temperature management (TTM) has shown to reduce brain damage after an out-of-hospital cardiac arrest (CA), but the time to neurological recovery is not defined yet. We sought to determine the time these patients need to regain consciousness, as well as factors associated with a late post-arrest awakening. METHODS: We performed a retrospective analysis of patients cooled to 32-34°C during 24h after CA, who regained neurological responsiveness after rewarming...

BACKGROUND: Temperature management is a recommended part of post-resuscitation care of comatose survivors of cardiac arrest. A number of methods exist for temperature management, all of which have limitations. We aimed to evaluate the performance and ease of use of a new esophageal heat transfer device (EHTD; Advanced Cooling Therapy, Chicago, IL, USA) for temperature management of adult survivors of cardiac arrest. METHODS: We performed a prospective study from March to June 2015...

Neurological recovery often determines outcome in patients resuscitated after cardiac arrest. Temperature control as a neuroprotective strategy has become standard of care. The first randomized trials showing improved neurological outcomes in patients treated with hypothermia with a target temperature of 33°C over a decade ago led to the inclusion of this intervention in practice guidelines and the broad adoption of hypothermia protocols across the world. More recently, large randomized trials showed no difference from targeting a temperature of 33 or 36°C and no benefit from pre-hospital induction of hypothermia...

BACKGROUND: Clinical trials supporting the use of therapeutic hypothermia (TH) in the treatment of out-of-hospital cardiac arrest (OHCA) are based on small patient samples and do not reflect the wide variation in patient selection, cooling methods, and other elements of post-arrest care that are used in everyday practice. This study provides a real world evaluation of the effectiveness of post-arrest care in TH centers during a time of growing TH dissemination in the state of New Jersey (NJ)...

Slow cooling leads to a passive dehydration of cells, whereas rehydration during warming reflects the active regain of functionality. The ability to modulate such an energy demanding process could be instrumental in optimizing the cryo-arrest of living systems. In the present study, various levels of hypertonic stress were used to disturb the water content of cells and to define the energy profiles of aquaporins and (Na(+) conducting) cation channels during rehydration. Na(+) import was found to be the rate-limiting step in water restoration, whereas aquaporins merely played a permissive role...

BACKGROUND: Systemic hypertension and left ventricular hypertrophy (LVH) are major risk factors of cardiac arrest. However, the impacts of hypertension and LVH on the outcome of cardiopulmonary resuscitation (CPR) and post-resuscitation hypothermia are still undetermined. METHODS: After 4 min of untreated ventricular fibrillation (VF) and 4 min of CPR, defibrillation was attempted in 16 male spontaneously hypertensive rats (SHR) with LVH and 16 male normotensive Wistar Kyoto (WKY) rats...

BACKGROUND: Mild hypothermia and fever control have been shown to improve neurological outcomes post cardiac arrest. Common methods to induce hypothermia include body surface cooling and intravascular cooling; however, a new approach using an esophageal cooling catheter has recently become available. METHODS: We report the first three cases of temperature control using an esophageal cooling device (ECD). The ECD was placed in a similar fashion to orogastric tubes...

For more than a decade, mild induced hypothermia (32 °C-34 °C) has been standard of care for patients remaining comatose after resuscitation from out-of-hospital cardiac arrest with an initial shockable rhythm, and this has been extrapolated to survivors of cardiac arrest with initially nonshockable rhythms and to patients with in-hospital cardiac arrest. Two randomized trials published in 2002 reported a survival and neurological benefit with mild induced hypothermia. One recent randomized trial reported similar outcomes in patients treated with targeted temperature management at either 33 °C or 36 °C...

BACKGROUND: Hypothermia is utilized in cardiac and aortic surgery to protect organs from ischemic reperfusion injury. Although the cooled body is invariably rewarmed after the procedure, it is still unknown whether the rewarmed body regains its former biological state. This study determined the modulatory effects of hypothermia on the human myocardial proteome and whether subsequent rewarming restores the proteome to the state prior to cooling. METHODS AND RESULTS: A quantitative proteomic analysis was performed using isobaric tags for relative and absolute quantification labeling tandem mass spectrometry...

Targeted temperature management (TTM) in today's modern era, especially in intensive care units represents a promising multifaceted therapy for a variety of conditions. Though hypothermia is being used since Hippocratic era, the renewed interest of late has been since early 21(st) century. There have been multiple advancements in this field and varieties of cooling devices are available at present. TTM requires careful titration of its depth, duration and rewarming as it is associated with side-effects. The purpose of this review is to find out the best evidence-based clinical practice criteria of therapeutic hypothermia in critical care settings...
