Since the 90's the concept of morphine sparing and morphine free anaesthesia (OFA) has progressively developed in non-cardiac surgery. The principle is based on the fact that in a sleeping patient a sympathetic reaction marked by hemodynamic modifications does not translate into a painful phenomenon, that a painful phenomenon in a sleeping patient is not memorized, that hormonal stress, the sympathetic reaction and the inflammatory reaction can be controlled by other therapeutic classes than a morphine agent. This therapeutic management would avoid the side effects associated with the use of morphine. In this hypothesis, OFA is more and more practiced in various situations without the real impact in terms of clinical benefit being clearly demonstrated. In cardiac surgery, some centers practice OFA with various protocols.The purpose of this work is to retrospectively evaluate over a defined period the incidence of postoperative complications, length of stay in the ICU/hospital, and death rate between patients managed with/without OFA based on lidocaine.
