The Effect of Sensory Stimuli With Familiar Voice and Patient's Auditory Preferences on the Level of Consciousness of Brain Injury Patients Admitted to Intensive Care Units

One of the consequences of brain injury is coma. On the other hand, complications that threaten comatose patients in ICU wards are a risk factor for sensory deprivation.

The aim of this study was to compare sensory stimuli with familiar sound and patient auditory preferences on the level of consciousness of patients in coma admitted to intensive care units.

The present study is a Interventional study of three groups before and after  that was performed on 45 patients admitted to the intensive care unit of selected hospitals in Ahvaz in 1399. Patients with inclusion criteria were randomly divided into two intervention groups and a control group. The minute was broadcast on the patientchr('39')s bedside for 3 days from the beginning of admission and twice a day (6 times in total) at 10 am and 3 pm on the patientchr('39')s bed. Routine care was performed for the control group and routine sounds were given. Awareness level was collected 15 minutes before and 15 minutes after the intervention in all three groups. The instrument for assessing patientschr('39') level of consciousness was GCS and FOUR scale. Descriptive and inferential statistical methods were used to analyze the data.

The mean level of consciousness of the auditory preferences and familiar voice group after the intervention was significantly higher than the control group (P <0.05) but there was no significant difference between the two groups of auditory preferences and familiar voice (P> 0.05).

Considering that the effect of familiar sound and hearing preferences has been more than unfamiliar sound, it is recommended to provide a program of auditory stimulation with familiar voice and hearing preferences for some patients in ICU wards
