Aripiprazole for prevention of delirium in the neurosurgical intensive care unit: a double-blind, randomized, placebo-controlled study

Aripiprazole for prevention of delirium in the neurosurgical intensive care unit: a double-blind, randomized, placebo-controlled study:

Abstract



Purpose

Delirium is reported in over 50% of critically ill ICU patients, and is associated with increased mortality and long-term cognitive consequences. Prevention and early management of delirium are essential components of ICU care. However, pharmacological interventions have not been effective in delirium prevention. This study investigated the effect of aripiprazole in the prevention of delirium in a neurosurgical intensive care unit.




Methods

In this prospective, randomized placebo-controlled small clinical trial, 53 patients, 18 to 80 years old, were randomized to receive enteric aripiprazole (15 mg) or placebo for up to 7 days. Delirium, detected by the Confusion Assessment Method-ICU, ICU events, laboratory studies, aripiprazole safety, time to delirium onset, delirium-free days, delirium prevalence during follow-up and ICU length of stay were recorded.




Results

Forty patients with similar baseline characteristics, including age, sex, neurosurgery types and APACHE II scores, completed the study. Delirium incidence and the mean days to its onset were 20% vs. 55% (p = 0.022) and 2.17 ± 0.41 vs. 2.09 ± 0.30 (p = 0.076) in the aripiprazole and placebo groups, respectively. The mean number of delirium-free days were: 5.6 (95%CI, 4.6-6.5) and 4.3 (95%CI, 3.2-5.4), in aripiprazole and placebo groups, respectively (p = 0.111). The prevalence of delirium during the follow-up was significantly lower in the aripiprazole group (p = 0.018). Serious aripiprazole adverse reactions were not observed.




Conclusions

Aripiprazole can reduce the incidence of delirium in the neurosurgical ICU. Studies with larger sample size in diverse ICU settings and longer follow-up are needed to confirm our findings.
