Analgesia/nociception monitoring for opioid guidance: meta-analysis of randomized clinical trials

Monitoring analgesia/nociception is often reliant on regular physiologic conditions, like sinus rhythm. Opioid guidance dependent on analgesia/nociception monitoring during anesthesia may have beneficial and clinically relevant effects, however the number of currently available randomized controlled studies is low and conclusions are hampered by heterogeneity. More studies with focussed clinical endpoints are therefore needed.
