“…However, the largest obstacle in controlling the fever response is the arteriovenous shunts and systemic vasodilation/vasoconstriction [49,[60][61][62] . Interventions that relax sphincters or produce vasodilatation (i.e., magnesium, propofol) result in superior heat transfer [62] . Arguably, the fastest method of heat exchange would be to directly cool the core organs.…”

Used for over 3600 years, hypothermia, or targeted temperature management (TTM), remains an ill defined medical therapy. Currently, the strongest evidence for TTM in adults are for out-of-hospital ventricular tachycardia/ventricular fibrillation cardiac arrest, intracerebral pressure control, and normothermia in the neurocritical care population. Even in these disease processes, a number of questions exist. Data on disease specific therapeutic markers, therapeutic depth and duration, and prognostication are limited. Despite ample experimental data, clinical evidence for stroke, refractory status epilepticus, hepatic encephalopathy, and intensive care unit is only at the safety and proof-of-concept stage. This review explores the deleterious nature of fever, the theoretical role of TTM in the critically ill, and summarizes the clinical evidence for TTM in adults.

“…3,4 These include increased bleeding during surgery, increased infection rates, increased length of stay, as well as, ultimately, a higher mortality rate. 1,5,6 Perioperative normothermia has also been shown to reduce postoperative complications. 3 Most recently it has been suggested that active warming commencing preoperatively is more effective in achieving normothermic admission temperatures to postanesthesia recovery than warming commenced intra-operatively.…”

Perioperative temperature management is imperative for positive surgical outcomes. This study assessed the clinical and wellbeing benefits of extending normothermia by using a portable warming gown. A total of 94 patients undergoing elective surgery were enrolled. They were randomized pre-operatively to either a portable warming gown or the standard warming procedure. The warming gown stayed with patients from pre-op to operating room to postrecovery room discharge. Core temperature was tracked throughout the study. Patients also provided responses to a satisfaction and comfort status survey. The change in average core temperature did not differ significantly between groups (P ¼ 0.23). A nonsignificant 48% relative decrease in hypothermic events was observed for the extended warming group (P ¼ 0.12). Patients receiving the warming gown were more likely to report always having their temperature controlled (P ¼ 0.04) and significantly less likely to request additional blankets for comfort (P ¼ 0.006). Clinical outcomes and satisfaction were improved for patients with extended warming.

“…Heat loss results from the transfer of heat from core blood vessels and tissues to peripheral vessels located in the cutaneous tissue. Processes of conductive and convective heat flow will promote heat transfer (Plattner et al ., 1996). Peripheral vasodilation will facilitate the process of heat transfer through convection and conduction, therefore promoting the loss of heat from the body to the surrounding environment (Kurz et al ., 1996).…”

A review of the literature was undertaken to determine the existence of any evidence to support cooling strategies used in the ICU. The focus of the review was to examine previous findings on the specific problems of cooling patients with severe cerebral insult. Cooling methods that use external physical cooling strategies as well as the effects of antipyretics and vasoactive drugs were examined. Overall, it would appear that conclusions for practice remain unclear. The findings led to the implementation of a pilot study, the findings of which will be discussed in Part 2.
