The Effects of Erector Spinae Plane (ESP) Block on Surgery-related Stress Response in Cardiac Surgery With ERAS

Surgery-induced pain reveals its own metabolic and inflammatory responses, resulting in a further increase in noxious pathways that are already occurring. Even though it is difficult to distinguish whether the metabolic and inflammatory responses are pain-induced or surgical-induced, it is clear that pain can cause a response. This study aims to investigate the effects of erector spinae plane block on surgery-related stress response with enhanced recovery after cardiac surgery protocol.
