title: Effect of auditory stimulation on traumatic coma duration in intensive care unit of Medical Sciences University of Mazandarn, Iran.
abstract: BACKGROUND
  Sensory deprivation is one of the common complications of coma patients in the intensive care unit (ICU). The purpose of this study was to investigate the impact of a familiar voice to consciousness level in coma patients.
  
  
  METHODS
  A total of 13 patients with traumatic coma (8 ≥ Glasgow's coma scale [GCS]) admitted in ICU ward were randomly assigned to control and experimental groups. The experimental group was treated twice a daily each time 15 min with a familiar recorded MP3 sound for 2 weeks. The control group received only natural voices of environment. GCS applied to evaluate patients' level of consciousness.
  
  
  RESULTS
  Findings showed that duration to reach GCS = 15 was significantly shorter in the experimental group (χ(2) = 12/96, P < 0/001).
  
  
  CONCLUSIONS
  These findings imply that providing familiar auditory stimulation programs for coma patients in the ICU could be effective.
