Summary

Delirium is an acute cerebral dysfunction syndrome characterized by acute fluctuating changes in consciousness, cognitive dysfunction, and disorientation. It's especially common in critically ill patients of emergency intensive care units and seriously threatens the survival and prognosis of patients and causes heavy economic burdens to the family, society, and medical service system. Impaired verbal communication, unfamiliar medical personnel, physical restraint, spatial-temporal disorientation, mechanical ventilation and sedation medication use can lead to a lack of adequate sensory stimulation and a high risk of delirium. Acoustic stimulation as a non-invasive non-pharmacological intervention can provide some sensory stimulation as a surrogate for critically ill patients. This research designs the content scripts from the needs of ICU patients and families for sound stimulation. The goal of this randomized controlled study is to test the effect of auditory stimulation by family voices in preventing delirium among sedative patients in emergency Intensive care units.

Detailed description

Patients are separated from their families and society under the closed management of the intensive care unit, the use of sedative drugs, mechanical ventilation, impaired verbal communication, physical restraint, environmental noise, and prolonged light exposure, which lead to a lack of adequate sensory stimulation, causing sensory deprivation in patients to some extent. In turn, sensory deprivation may cause multisensory perceptual confusion and hallucinations, affecting patients' orientation and thinking and triggering delirium, so providing appropriate sensory stimulation to critically ill patients may help to improve patients' orientation and attention, correct patients' thinking confusion and prevent delirium, and in clinical practice, sensory stimulation is considered as an important part of multicomponent delirium prevention programs.

Conditions

• Delirium

Interventions

Type	Name	Description
OTHER	structured family voice stimulation	The structured family voice stimulation is played to the patients for the first five days after admission to eicu until transfer out or death. The content of the recording is developed according to the structured script.
OTHER	unstructured family voice stimulation	The unstructured family voice stimulation is played to the patients for the first five days after admission to eicu until transfer out or death.
