“…More recently, a forced-air cooling device has been introduced into clinical practice. 35) Cooling by convection has been proven effective in decreasing central nervous system and core temperature within the range of cerebral protection in animals and humans without impairing tissue oxygen delivery. 35) Most cooling devices are equipped to automatically adjust the body temperature.…”

Objective Commonly, brain temperature is estimated from measurements of body temperature. However, temperature difference between brain and body is still controversy. The objective of this study is to know temperature gradient between the brain and axilla according to body temperature in the patient with brain injury. Methods A total of 135 patients who had undergone cranial operation and had the thermal diffusion flow meter (TDF) insert were included in this analysis. The brain and axilla temperatures were measured simultaneously every 2 hours with TDF (2 kinds of devices: SABER 2000 and Hemedex) and a mercury thermometer. Saved data were divided into 3 groups according to axillary temperature. Three groups are hypothermia group (less than 36.4°C), normothermia group (between 36.5°C and 37.5°C), and hyperthermia group (more than 37.6°C). Results The temperature difference between brain temperature and axillary temperature was 0.93±0.50°C in all data pairs, whereas it was 1.28±0.56°C in hypothermia, 0.87±0.43°C in normothermia, and 0.71±0.41°C in hyperthermia. The temperature difference was statistically significant between the hypothermia and normothermia groups ( p =0.000), but not between the normothermia and hyperthermia group ( p =0.201). Conclusion This study show that brain temperature is significantly higher than the axillary temperature and hypothermia therapy is associated with large brain-axilla temperature gradients. If you do not have a special brain temperature measuring device, the results of this study will help predict brain temperature by measuring axillary temperature.

“…Hypothermia is applied to patients according to the principles of convection (e.g., surface cooling methods such as forced air cooling via full cooling blankets or air beds) and conduction (e.g., liquid circulating in water-filled mattress) [57]. If a surface cooling method is used, it is frequently combined with other body cooling methods such as alcohol on the skin, ice bags, intravenous cold infusion, gastric lavages or cold-fluid infusion combined with icewater cooling blanket, to achieve the programmed Tcore target [15,40,57,58].…”

The main surface cooling method limitations are: a) the speed at which the target temperature is achieved is lower than that of intravascular systems, b) patients who are morbidly obese cannot be treated optimally with these cooling methods, and c) these methods could require greater effort on the part of the medical and paramedical team to maintain adequate management.…”

“…To get most benefit, vigorous patient cooling should be undertaken as soon as possible post-arrest to decrease core temperature to 33°C. 38 There are several methods to induce mild hypothermia. These methods can be categorised as non-invasive (external cooling) and invasive (internal cooling).…”

Underlying mechanisms of neuronal injury after cardiac arrest After cardiac arrest, severe neurological impairment is a major problem. Only 10-20% patients are discharged with no significant neurological deficit. 9 Damage to the neurons in the central nervous system occurs during cardiac arrest, phase 1 (no flow) and during the cardiopulmonary resuscitation, phase 2 (low flow). 10 This period of no or low blood flow also primes the brain for further
