Comparison of the Analgesic Effects of Ultrasound Guided Pectoral Nerve Block Type II and Erector Spinae Plane Block in Breast Cancer Surgery

Abstract

Objectives: To compare the effect of ultrasound guided Pectoral Nerve Block 2 (PECs 2) and Erector Spinae Plane Block (ESP) for post op analgesia in patients undergoing Breast cancer surgery Methods: This observationally planned study included 40 patients over the age of ages of 18 who are of American Society of Anesthesiologists (ASA) I-III and scheduled for elective surgery due to breast malignancy were included in the study. PECs 2 block was applied to the patients after the induction of general anesthesia in Group 1 and ESP block was applied to the patients after the induction of general anesthesia in Group 2. In the postoperative period, visual analog scale (VAS) values, nausea, vomiting and sedation score values and analgesic doses used by all patients in the post-operative period were recorded. Results: Intraoperative and postoperative opioid consumption was statistically significantly lower in the PECs block group than in the ESP group. Postoperative analgesia time was longer in the PECs group. The number of patients requiring rescue opioid in the post-operative period was statistically significantly lower in the PECs group. There was no difference between the groups in terms of complications, mobilization time, time of discharge, postoperative nauseavomiting (PONV) and terms of sedation. Conclusions: In patients who underwent breast surgery for malignancy, we found that the ultrasound (US) guided PECs 2 block achieved more effective postoperative analgesia compared to ESP block.
