Effect of PECS II, Parasternal and Serratus Plane Blocks on Postoperative Pain in MIDCAB Surgery

AIM: It was aimed to evaluate the effectiveness of pectoral nerve block (PECS II), parasternal and serratus plane blocks in postoperative analgesia in minimally invasive cardiac surgery (MIDCAB).

INTRODUCTION: The frequency of minimally invasive cardiac surgery has increased in recent years. With this method, Coronary artery bypass graft (CABG) operations can be performed without sternotomy. It is a beneficial method for early postoperative mobilization, early recovery and better aesthetic appearance. Since there is a surgical intervention between the ribs, pain control is important in these patients.

METHOD: In the preoperative evaluation of patients planned for CABG, PECS II, parasternal and serratus plane blocks are routinely recommended for postoperative pain control. Consent for the procedure is obtained from patients who accept this procedure. After induction and before the surgical incision, these block applications are performed under sterile conditions under the guidance of ultrasonography. Standard intravenous analgesic agents are applied to our patients who do not accept block applications. The hospital core system files of our patients who underwent cardiac surgery with minimally invasive intervention in our hospital between January 1, 2021 and December 31, 2021 will be scanned retrospectively. Patients with and without block application will be divided into two groups. From our patients' files; Demographic data, extubation time, drain site and incision site pain at the 1st, 2nd, 4th, 12th, 24th, 48th and 72nd hours after extubation will be noted. In addition, it will be noted whether there is a need for additional rescue analgesia in cases where block is performed. The data obtained will be evaluated statistically and the results will be published in national or international scientific journals.
