Background. Severe traumatic brain injury (TBI) is one of the causes contributing death and disability worldwide. Patients suffering from severe TBI usually will end up with disability, as they are associated with extensive damages to the brain. This makes the management of severe TBI to be challenging, Objective of the study. The study aims to use a Peltier effect device in severe TBI patients as a method of local hypothermia, because therapeutic hypothermia showed promising results in reducing secondary tissue injury and intracranial pressure after TBI. Material and Methods. Thermoelectric coolers (TECs) based on the Peltier effect are preferred for hypothermia because they have small size, low weight, lack of moving parts, high precision and safe operation. For the purpose of the study a therapeutic hypothermia device was assembled, software for the device was designed, as well a graphical user interface (GUI). The TEC helmet was assebled and tested. Results. Computer simulations and mathematical calculations were made prior to assembly, the dimensions and location of the Peltier elements in the helmet were adjusted to the simulation results, with elements dimensions 40x40 mm, and placement on temporal, parietal and occipital regions and divided in two sides controlled by 2 separate microcontrollers to allow cooling of a more specific region of the head. Previous studies suggest that local cooling devices of the brain were effective at achieving a brain temperature 34°C within a 2–6 h time frame while available systems were not adequate to achieve this desired goal, so further research into local cooling systems is needed. Conclusion. There is a possibility to implement this device for local hypothermia in the clinical settings, for this purpose a RCT is being designed to test the efficacy of the device, because there is an ongoing debate about local hypothermia efficacy in TBI in clinical trials compared to laboratory ones. |
