A systematic review and meta-analysis of the clinical efficacy of the intravenous injection of dexmedetomidine in ICU patients with hyperactive brain syndrome.

Background: The incidence of hyperactive brain syndrome in patients in the intensive care unit (ICU) is very high. Compared with other sedative drugs, existing research shows that dexmedetomidine can significantly reduce the incidence of hyperactive brain syndrome. This study systematically analyzed the clinical efficacy of a dexmedetomidine intravenous injection in ICU patients with hyperactive brain syndrome.

Systematic review and meta-analysis of the sedative effects and safety of dexmedetomidine in patients after cardiac surgery.

Background: In order to increase the sample size and improve the test efficiency from a statistical perspective, we conducted a combined analysis of multiple results from similar studies. In this study, we conducted a meta-analysis to investigate the sedative effect of dexmedetomidine on patients after cardiac surgery, so as to provide theoretical basis and help for clinical treatment of cardiac diseases.

Methods: The Boolean logic search method was employed to search online databases for publications, with "dexmedetomidine", "cardiac surgery", "competitive antagonist", and "analgesic sedation" used as keywords.
