Key result
Multimodal low-opioid anesthesia significantly reduced interleukin-6 levels by 27.51% after cardiopulmonary bypass compared to standard anesthesia.
Why the study?
Patients undergoing CABG face risks from surgical trauma and homeostatic changes provoked by anesthetics and cardiopulmonary bypass.
Does a low-opioid anesthesia scheme reduce pro-inflammatory IL-6 levels and improve clinical outcomes in patients undergoing CABG with cardiopulmonary bypass?

Does a low-opioid anesthesia scheme reduce pro-inflammatory IL-6 levels and improve clinical outcomes in patients undergoing CABG with cardiopulmonary bypass?
A multimodal low-opioid anesthesia strategy during CABG significantly blunts the pro-inflammatory IL-6 response and is associated with improved early postoperative outcomes compared to standard opioid-based anesthesia.
Answers are grounded in this paper and cite their sources.
Multimodal low-opioid anesthesia was associated with lower IL-6 and faster recovery after CABG; leaves open whether it warrants practice change pending larger trials.
INTRODUCTION: With coronary artery bypass grafting, patients are subjected to additional risk caused by both surgical treatment itself and pathophysiological changes in homeostasis, provoked by the action of anesthetics and cardiopulmonary bypass. MATERIAL AND METHODS: The study involved 60 patients, who had been subjected to coronary artery bypass grafting with cardiopulmonary bypass. All patients were divided into two groups: group I (30 patients) - low-opioid scheme of anesthesia and group II (30 patients) - standard scheme of anesthetic management. Blood interleukin-6 (IL-6) was identified before and after cardiopulmonary bypass using an ELISA test. CONCLUSIONS: Application of multimodal low-opioid anesthesia was associated with significantly lower IL-6 at the end of surgery, shorter mechanical ventilation duration, less frequent low cardiac output syndrome and need for catecholamines, and shorter ICU stays.

Maruniak et al. (2020) conducted an RCT in Coronary heart disease (n=60). Low-opioid anesthesia vs. Standard anesthesia (fentanyl 20-25 µg/kg) was evaluated on Blood interleukin-6 (IL-6) level after cardiopulmonary bypass (27.51% reduction, p=0.001). Multimodal low-opioid anesthesia significantly reduced interleukin-6 levels by 27.51% after cardiopulmonary bypass compared to standard anesthesia.
