Opportunities for family interaction with comatose patients are often strictly limited. Some studies have indicated that family visits to the ICU have detrimental effects on physiologic parameters such as blood pressure and heart rate. This study was undertaken to investigate the effects of taped messages by a family member on key measures of physiological functioning in comatose head-injured patients in intensive care units. ⋯ Research to date represents conflicting results. This study demonstrated no untoward effects with exposure to taped familial messages, including no changes in intracranial pressure (ICP), blood pressure, pulse, respiratory rate, mean arterial pressure, oxygen saturation level, or level of restlessness. The findings support allowing family interactions with comatose head-injured patients in the ICU.
