The effect of Dyangs’ sensory stimulation on the level of consciousness, pain and restlessness in ventilated patients: a clinical trial study

Pain and restlessness are common problems in the intensive care unit. Sensory stimulation is one of the non-pharmacological methods of pain control. Dyang sensory stimulation includes visual, auditory, olfactory, tactile, and motor-sensory stimulation. In this study we investigated the effects of Dyang sensory stimulation on the level of consciousness, pain, and restlessness in the unconscious patients.

This clinical trial included 60 patients under mechanical ventilation. The patients were divided into two groups. The intervention group received Dyang sensory stimulation. Sensory stimulation was performed for one hour in the evening and at night for six consecutive days. Fifteen minutes after sensory stimulation, the level of consciousness, pain, and restlessness were measured using GlasgowComa Scale  , BPS (Behavioral Pain Scale), and Rass (Richmond Agitation Sedation Scale), respectively.

The mean values for level of consciousness of the patients in the two groups before the intervention were below 7. The mean values for pain intensity (p=0.684) and restlessness (p=0.739) did not show any significant differences between the two groups before the intervention. After sensory stimulation on the second day, the level of consciousness of the patients in the intervention group increased compared to that in the control group (p=0.016). However, there were no significant differences between the two groups in terms of pain intensity and restlessness on all days of the study (p>0.05).

Dyang sensory stimulation can increase the level of consciousness.  Therefore, this multidimensional stimulation method can be used in the patients under mechanical ventilatation.
