The guided imagery intervention included two sessions, each lasting 60 minutes, offered during morning weaning trials from mechanical ventilation.
Measurements were recorded at baseline and 30- and 60-minute intervals, and included vital signs and Richmond Agitation-Sedation Scale (RASS) scores. Sedative and analgesic medication volume consumption were recorded 24 hours prior to and after the intervention.
The guided imagery group had significantly improved RASS scores and reduced sedative and analgesic volume consumption.
Additionally, during the second session, oxygen saturation levels significantly improved as compared to the comparison group.
In all, the guided imagery group had 4.88 fewer days of mechanical ventilation and 1.4 days less hospital length of stay, as compared to the comparison group.
The investigators conclude that guided imagery is a promising intervention during mechanical ventilation weaning.
