Background and objective: The brain temperature is an important physiological parameter which reflects changes in neuronal activity as well as the various functions of nervous. The rectal and axillary methods take relatively higher time and cost than tympanic method (less than 10 seconds). Thus, it can be said that tympanic temperature is more convenient while it is very close to the brain temperature. The aim of this study is to examine the tympanic temperature as well as its relationship with the survival in comatose patients.

Methods: The study population included all patients admitted to the ICU in a university hospital in Khorramabad, with GCS between 3 and 11 and a decreased level of consciousness caused by traumatic brain injury. The generalized estimating equations was used to investigate the relationship between tympanic temperature and other variables. Also a Cox regression was used to determine the survival in ICU patients.

Results: In this study, most patients did not experienced MI, CVA, diabetes, smoking and alcohol. About 53% of patients were diagnosed by trauma. Also, 36% of patients had bilateral cerebral hemorrhage and 31% of them did not have a brain hemorrhage. The results of generalized estimating equations, shown a significant inverse relationship between cerebral hemorrhage and left tympanic temperature. Also according to the Cox regression analysis, there was a significant relationship between the survival time in ICU and tympanic temperature.

Discussion: Regarding the significant effect of tympanic temperature on survival in ICU and also the simplicity of this method, this could be a useful measurement in regular checklist for ICU patients.
