Comment on “Sedative and Analgesic Effects of Entonox Gas Compared with Midazolam and Fentanyl in Synchronized Cardioversion”

Abstract EN

In the recent investigation of Masoumi et al.

[1], the intravenous association of midazolam and fentanyl was compared to inhaled nitrous oxide in the synchronized cardioversion.

This study is very important since several drug schemes have been used for anesthesia during electrical cardioversion, with different mechanism of action, duration, and side effects, but, until now, no technique demonstrated a clear superiority over one another [2].
