Clinical Trial Summary

Elderly critically ill patients in the intensive care unit (ICU) are at risk of delirium, which is primarily characterized by acute consciousness impairment and perceptual, cognitive, and memory impairment, resulting in excess death, care expenditures, and acquired dementia, depression and anxiety, which severely affect the prognosis of critically ill patients. However, there are currently no effective pharmacological strategies for preventing delirium. Inhalation aromatherapy has been proven to benefits the sleep disorder, anxiety or depression and lavender oil is one of the most used essential oils. Therefore, we hypothesized that the use of lavender would reduce the incidence rate of delirium in ICU patients.


Description:

This trial was designed to be a randomized, single-center, double-blind, placebo-controlled trial. A total of 68 elderly patients from two ICUs will be randomly allocated at a 1:1 ratio to the intervention group or the control group. Both groups will receive the ABCDEF (A2F) bundle strategy recommended by guidelines, a multicomponent approach including pain and delirium management, breathing trial practice, analgesic and sedation usage control, family engagement and so on, to prevent delirium. The intervention group will additionally receive aromatherapy lasting for five days. The primary outcome is the prevalence of delirium. Secondary outcomes include the severity and duration of delirium, the length of ICU stay, the duration of physical restraint, the duration of analgesic and sedative medication and the 28-day mortality rate. We will use the CAM-ICU and CAM-S to measure the prevalence and severity of delirium, and analyses of variance (ANOVAs) or repeated-measures ANOVAs and Wilcoxon rank-sum tests to analyze the observation results.

Outcome

Type Measure Description Time frame Safety issue
Primary the prevalence of delirium Assessment will be performed during the study period for all enrolled participants in a timely manner using the Confusion Assessment Method for the ICU (CAM-ICU). The CAM-ICU, a 2-minute assessment tool, has proven to be quick, valid, and reliable for the diagnosis of delirium in the ICU, making it beneficial for use in both clinical and research contexts. Through study completion, an average of 1 year (November 31, 2023-November 31, 2024)
Secondary Severity of delirium Throughout the study, the Confusion Assessment Method-Severity scale will be administered in each included patient. The total score of the Confusion Assessment Method-Severity scale can vary between 0 and 7, where 7 indicates the most severe condition. Through study completion, an average of 1 year (November 31, 2023-November 31, 2024)
Secondary Duration of delirium Once delirium is diagnosed, the investigators will record its duration of the patient tests positive for the Confusion Assessment Method for the ICU (CAM-ICU) Through study completion, an average of 1 year (November 31, 2023-November 31, 2024).
