Cardiac Index and General Anesthesia Without Opioid.

• Status: Recruiting
• Trial end date: 2024-01-02
• Target enrollment: 0
• Participant gender: All

Summary

General anesthesia used to be based on the association of hypnotics and opioïd drugs. But recent studies showed that opioïds may be related to a many different complications, like respiratory distress, hyperalgesia.

Opioïd free anesthesia (OFA) aim is to control de cardiovascular nociceptive response to the surgical stimulation. The scientific literature is not clear yet on the cardiovascular effect of the OFA. Optimization of the cardiac index proved its worth in reducing morbidity and mortality.

The purpose of this study is to increase our understanding of the impact of opioid free anesthesia on the cardiovascular system and to evaluate the effectiveness and the security of the technic.
