Background/AimIn open heart surgery, sternotomy causes inflammation in tissues, and inflammation causes postoperative pain. This study aims to examine the effects of bilateral erector spinae plane (ESP) blocks on postoperative extubation time and laboratory parameters in open heart surgery.Materials And MethodsThe study was managed using retrospective data from 85 patients who underwent open-heart surgery. Patients who received intravenous analgesia and were transferred to the intensive care unit with intubation were included in the study. Two groups were formed: those who received preoperative bilateral ESP block (ESB) and those nonblock (NB). Statistical significance was investigated between ESB and NB in terms of extubation time and laboratory parameters.ResultsThe postoperative extubation time for group NB was significantly longer at 360 (300-420) min compared to the observed 270 (240-390) min for ESB (p: 0.006). The length of stay in the intensive care unit was also longer for group NB at 4 (3-5) days compared to 3 (3-4) days for ESB (p: 0.001). Ejection fraction values, cardiopulmonary bypass, and aortic cross-clamp times were similar in both groups. Postoperative 24 h troponin I levels were higher for group NB at 0.94 (0.22-2.70) mcg/L compared to 0.16 (0.06-1.40) mcg/L for group ESB (p: 0.016).ConclusionIt would be useful for anesthesiologists to know that erector spinae plane blocks applied in the preoperative period in cardiac surgeries not only shorten the mechanical ventilation and hospitalization times but also provide lower troponin values in the postoperative period patient follow-ups.© TÜBİTAK.
