Cardiac Index and General Anesthesia Without Opioid. — OFFLOW  

Hip Arthropathy Clinical Trial

Official title:
Comparative Study of General Anesthesia With or Without Opioid on the Cardiac Index During Total Hip Arthroplasty

Clinical Trial Summary

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

Clinical Trial Description

General anesthesia used to be based on the association of hypnotics and opioid drugs. But recent studies showed that opioïds may be related to a many different complications, like respiratory distress, hyperalgesia etc… Those sides effects are known, but there might be some recent technics that could allow anesthesiologist to reduce those unintended symptoms. As surgery became an important pilar of the modern medicine even in fragile people, the weight of opioids sides effect increased. Opioid free anesthesia (OFA) consists in the simultaneous administration of alpha2-agonist (for example the dexmedetomidine (DEXDOR)), sodium channel blocker (lidocaine), and N-methyl-D-aspartate (NMDA) antagonists receptors (Ketamine). Its 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 investigators thinks that exploring the impact of two different general anesthesia technics on cardiac index, might allow anesthesiologists to have a better understanding of the anesthetic strategy applied to the patient. General anesthesia with or without opioid is used on a daily basis at the hospital center of Montauban. The possible sides effects of OFA as well as those affiliate to balanced anesthesia are known by all the care workers. 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. ;
