The effect of organized auditory stimulations on the consciousness level of comatose patients

Background & Aim: Higb frequency of traumatic and non-traumatic brain injuries in one hand and improvement of the health care condition to restore patientʹs life in the other hand bas increased the frequency of comatose patients in ICU. These patients often experience physical. cognitive, behavior or sensory defects, and the sensory input reduction in intensive care unit". expose them to cognition disorders. It seems that using sensory stimulation programs may he effective in preventing from sensory deprivation and facilitating recovery process. Methods & Materials: In this quasi-experimental study, 30 comatose patients who were hospitalized in reu in Shariati and Sina hospitals were sought to be studied, The subjects were selected randomly using matching that was placed in case and control group. In the intervention group. patients received an auditory stimulation for 2 weeks. 6 days of a week, 2 times a day. The auditory stimulator was a recorded tape 1.5-10 minutes) of a familiar voice for 30 minutes. The Glasgow Coma Scale (GCS) was used for measuring the level of consciousness (LOC). LOC was measured before and after each intervention 4 rimes a day. The control group LOr WdS measured in a similar manner to the case group. At the same time, hemodynamic symptoms (hlood pressure, pulse rate) and mean arterial pressure) were measured, Non-parametric test was used for analyzing data. The data was analyzed through ,SPSS V.II.S computer software. Results: The findings indicated that there was a significant difference in LaC of the intervention group at the first day and after fourteen days of the intervention (P
