The combination of general anesthesia with opioids is associated with a slow recovery of the gastrointestinal tract and other side effects of their systemic application. Therefore the search for alternative methods of pain relief in the context of Enhanced Recovery After Surgery protocols is becoming an increasingly relevant research topicn.
