Targeted Temperature Management at 33 Versus 36 Degrees: A Retrospective Cohort Study.

To determine the association between targeted temperature management goal temperature of 33°C versus 36°C and neurologic outcome after out-of-hospital cardiac arrest.

Control of Shivering During Targeted Temperature Management.

Targeted temperature management (TTM) is used frequently in patients with a variety of diseases, especially those who have experienced brain injury and/or cardiac arrest. Shivering is one of the main adverse effects of TTM that can often limit its implementation and efficacy. Shivering is the body's natural response to hypothermia and its deleterious effects can negate the benefits of TTM. The purpose of this article is to provide an overview of TTM strategies and shivering management.

Cold fluids for induction of targeted temperature management: A sub-study of the TTH48 trial.

Pre-intensive care unit (ICU) induction of targeted temperature management (TTM) with cold intravenous (i.v.) fluids does not appear to improve outcomes after in out-of-hospital cardiac arrest (OHCA). We hypothesized that this may be due to ineffective cooling and side effects.

Brain temperature of infants with neonatal encephalopathy following perinatal asphyxia calculated using magnetic resonance spectroscopy.

Little is known about brain temperature of neonates during MRI. Brain temperature can be estimated non-invasively with proton Magnetic Resonance Spectroscopy (H-MRS), but the most accurate H-MRS method has not yet been determined. The primary aim was to estimate brain temperature using H-MRS in infants with neonatal encephalopathy following perinatal asphyxia (NE). The secondary aim was to compare brain temperature during MRI with rectal temperatures before and after MRI.

Functional outcomes associated with varying levels of targeted temperature management after out-of-hospital cardiac arrest - An INTCAR2 registry analysis.

Targeted temperature management (TTM) after out-of-hospital cardiac arrest (OHCA) has been recommended in international guidelines since 2005. The TTM-trial published in 2013 showed no difference in survival or neurological outcome for patients randomised to 33 °C or 36 °C, and many hospitals have changed practice. The optimal utilization of TTM is still debated. This study aimed to analyse if a difference in temperature goal was associated with outcome in an unselected international registry populati...

Using Esophageal Temperature Management to Treat Severe Heat Stroke: A Case Report.

Exertional heat stroke (EHS) is defined by a core body temperature that exceeds 40°C with associated central nervous system dysfunction, skeletal muscle injury, and multiple organ damage. The most important initial focus of treatment involves reduction of patient temperature. First approaches to achieve temperature reduction often include ice packs, water blankets, and cold intravenous fluid administration. When these measures fail, more advanced temperature management methods may be deployed but often req...

CuMoO4 Bimetallic Nanoparticles, An  Efficient Catalyst  for Room Temperature C-S Cross-coupling of Thiols and Haloarenes.

Cu(II) catalyst is less efficient at room temperature for C-S cross-coupling. C-S cross-coupling by Cu(II) catalyst at  room temperature is not reported. But doping of copper  with  molybdenum metal has been realized here to be more efficient  for C-S cross-coupling in comparison to general Cu(II) catalyst. The doped catalyst CuMoO4 nanoparticle is found to be more efficient than copper. The catalyst works with mild condition without any ligand at room temperature.  The catalyst is recyclable and effec...

Efficacy of the cooling method for targeted temperature management in post-cardiac arrest patients: a systematic review and meta-analysis.

This review aimed to compare the efficacy of endovascular cooling devices (ECD), such as Thermogard®, with surface cooling devices (SCD), such as Arctic Sun®, in reducing mortality and improving neurological status for patients with post-cardiac arrest undergoing targeted temperature management.

Ultradian oscillations in brain temperature in sheep: implications for thermoregulatory control?

We compared body temperature patterns and selective brain cooling (SBC) in eight adult female sheep in an indoor (22-25 °C) and outdoor (mean ~ 21 °C) environment, by measuring brain, carotid arterial, and jugular venous blood temperatures at 5-min intervals using implanted data loggers. To investigate whether ultradian oscillations in brain temperature had thermoregulatory consequences for the sheep, we determined the cranial arterio-venous (AV) temperature difference as an indicator of respiratory...

Meta-analysis of targeted temperature management in animal models of cardiac arrest.

Targeted temperature management (TTM) of 32 to 34 °C has been the standard treatment for out-of-hospital cardiac arrest since clinical trials in 2002 indicated benefit on survival and neurological outcome. In 2013, a clinical trial showed no difference in outcome between TTM of 33 °C and TTM of 36 °C. In this meta-analysis, we investigate the evidence for TTM in animal models of cardiac arrest.

Improvement of Consciousness before Initiating Targeted Temperature Management.

Following cardiac arrest, return of spontaneous circulation (ROSC) in patients may be followed by spontaneous neurological recovery, which may decrease the potential adverse effects of treatments in post-cardiac arrest care, including those of Targeted Temperature Management (TTM). We investigated the percentage of post-arrest patients who experienced spontaneous neurological recovery, and the characteristics and neurological outcomes of these patients.

The usefulness of neuron-specific enolase in cerebrospinal fluid to predict neurological prognosis in cardiac arrest survivors who underwent target temperature management: a prospective observational study.

Cerebrospinal fluid (CSF) neuron-specific enolase (NSE) levels increase ahead of serum NSE levels in patients with severe brain injury. We examined the prognostic performance between CSF NSE and serum NSE levels in out-of-cardiac arrest (OHCA) survivors who had undergone target temperature management (TTM).

The Effects of Abnormal Body Temperature on the Prognosis of Patients with Septic Shock.

We aimed to use temperature and the area under temperature curve to represent the severity of abnormal body temperature of patients with septic shock and to observe their impact on the prognosis. Five hundred twenty-eight adult patients with septic shock admitted to intensive care unit (ICU) were analyzed. Within the first 24 hours and throughout the period in ICU, the maximum temperature (24hT, T), lowest temperature (24hT, T), and the temperature range (24hT, T) were aggregated. Patients were divided into...
