Benefit of immediate coronary angiography after out-of-hospital cardiac arrest in France: A nationwide propensity score analysis from the RéAC Registry.

Background: The survival rate of out-of-hospital cardiac arrest (OHCA) remains extremely low, generally under 10%. Post-resuscitation care, and particularly early coronary reperfusion, may improve this outcome. The main objective of the present study was to determine whether patients with immediate coronary angiography at hospital admission (CAA) had a better outcome than patients without immediate CAA.

Remifentanil induces consistent and sustained controlled hypotension in children during middle ear surgery.

Purpose: To determine in children whether remifentanil combined with sevoflurane, could induce controlled hypotension, reduce middle ear blood flow (MEBF) measured by laser-Doppler, and provide a satisfactory operative field.

Methods: Forty children undergoing middle ear surgery and anesthetized with sevoflurane were randomly assigned to receive either 1 micro g x kg(-1) remifentanil iv followed by a continuous infusion of 0.2 to 0.
