Objectives: (1) To check music and voice message influence on vital signs and facial expressions of patients in physiological or induced comas; (2) To connect the existence of patient's responsiveness with the Glasgow Coma Scale or with the Ramsay Sedation Scale.

Method: This was a randomized controlled clinical trial with 30 patients, from two Intensive Care Units, being divided in 2 groups (control and experimental). Their relatives recorded a voice message and chose a song according to the patient's preference. The patients were submitted to 3 sessions for 3 consecutive days.

Primary Outcome Measures:
  • Vital signs [ Time Frame: 3 days; before and after stimulus or silence ] [ Designated as safety issue: No ]

Enrollment: 30
Study Start Date: February 2004
Study Completion Date: September 2005
Primary Completion Date: March 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: silence
The control group listened "silence" and was evaluated the same things.
Other: Music and message
Experimental group: music and message Control group: silence
Other Name: Patients in state of coma or induced coma

Detailed Description:

The relatives elaborated a voice recorded message and choose a music according to the patient preference, which were recorded in the same Compact Disc. Two identical CD's were made at the same recorded time; one with and another one without stimulus in order to make the random division of the groups. The patients were evaluated according to one of the Scales; they used earphones. During the sessions, the data relating to the vital signs and the face expression were recorded in a data collection instrument.
