Opioid Free Anaesthesia Clinical Trial
Official title:
The Postoperative Opioid-Sparing Effect of an Intraoperative Pecto-Intercostal Fascial Block and Opioid-Free Anesthesia in Cardiac Surgery Patients: a Prospective Randomized Controlled Trial
The present study aims to assess the difference in postoperative opioid consumption between patients who intraoperatively receive a pecto-intercostal facial block combined with opioid-free anesthesia versus a traditional opioid-based regimen for cardiac surgery. The literature on opioid-free anesthesia for cardiac surgery is minimal and solely consists of case reports and retrospective studies. Nevertheless, these reports show the feasibility of opioid-free anesthesia. The purpose of this study is to assess the opioid-sparing effect and efficacy of combining an opioid-free anesthetic regimen with a pecto-intercostal fascial plane block (PIFB) in patients undergoing cardiac surgery. We hypothesize that opioid-free cardiac anesthesia with an intraoperative PIFB significantly reduces postoperative opioid consumption in comparison to a high-dose opioid intraoperative regimen.
Patients, aged 18 years or older, scheduled for coronary artery bypass graft surgery (CABG) with a complete midline sternotomy as surgical approach will be recruited for this study. Patients planned for this particular surgical procedure will be recruited and allocated to one of 2 groups: 1. "Intervention" group: Opioid-free anesthetic regimen with a pre-incisional pecto-intercostal fascial plane block (PIFB); 2. "Control" group: traditional opiate-based anesthetic regimen in which the dosage of the opioids is at the discretion of the attending anesthesiologist. Based on our power analysis, each group will consist of 64 patients. ;
