    Purpose: Breast surgery is an exceedingly common procedure and associated with an increased incidence of acute and chronic pain. Preemptive regional anesthesia techniques may improve postoperative analgesia for patients undergoing breast surgery. The aim of this study was to evaluate the effect of preoperative bilateral serratus plane block on postoperative opioid consumption in patients undergoing breast reduction surgery. Methods: After ethical board approval, 40 patients undergoing breast reduction surgery were randomized into 2 groups: control group (Group C, n = 20) and serratus plane block group (Group SPB, n = 20). Group C received bilateral ultrasound-guided 2 ml 0.9% saline subcutaneously each block side, Group SPB received ultrasound-guided bilateral SPB with 0.25% bupivacaine 30 ml each side. The groups were administered the routine general anesthesia protocol. All operations were performed with the mediocentral pedicled reduction mammaplasty technique by the same surgeon. Postoperative analgesia was performed intravenously in the 2 groups twice a day with dexketoprofen trometamol 50 mg and patient-controlled analgesia with fentanyl. Postoperative analgesia was evaluated using the visual analog scale (VAS). Fentanyl consumption, additional analgesia requirement and opioid-related side effects were recorded during the first 24 h after surgery. Results: Compared with control, the VAS score was statistically lower in the SPB group during all measurement times (p < 0.05). The 24-h opioid consumption was significantly higher in the control group compared with the SPB group (372.50 ± 39.65 vs. 296.25 ± 58.08 ?q, respectively; p < 0.001). In addition, the analgesia requirement was statistically lower in the SPB group (8/20 vs. 2/20, respectively, p < 0.028). Nausea or vomiting was observed more often in the control group than in SPB block (9/20 vs. 2/20, respectively, p = 0.013), whereas other side effects were similar for the two groups. Conclusions: SPB can be used safely bilaterally in the management of pain for breast reduction surgery as it is easy to perform, provides excellent analgesia, and reduces opioid consumption and opioid sparing effect.

    The effect of ultrasound-guided serratus plane block on the quality of life in patients undergoing modified radical mastectomy and axillary lymph node dissection: A randomized controlled study

    BACKGROUND: Modified radical mastectomy (MRM) and axillary lymph node dissection (AD) are the most commonly used surgical methods in breast cancer surgery, and they are characterized by moderate to severe pain. This study aimed to investigate the effect of ultrasound-guided serratus plane block (SPB) on postoperative acute and chronic pain in patients undergoing MRM and AD. METHODS: After ethical approval, 60 patients, aged between 18-65 years, ASA I-III, underwent unilateral MRM, and AD was assigned into 2 groups. The SPB group received ultrasound-guided SPB with 30 mL 0.25% bupivacaine, and the control group received 2 mL saline injection subcutaneously. Postoperative analgesia was performed with intravenous patient-controlled analgesia and dexketoprofen trometamol. Pain scores, opioid consumption, and rescue analgesic requirements were recorded. Chronic pain and quality of life were evaluated with the Numerical Rating Scale (NRS), short form-36 (SF-36), and painDETECT. RESULTS: Compared with the control group, the visual analogue scale scores were statistically lower in the SPB group during 4 postoperative hours in post-anaesthetic care unit PACU at 1st, 2nd (P < 0.001), and 4th hour (P = 0.014). Fentanyl consumption and rescue analgesics were lower in the SPB group than in the control group (0-4 h, P = 0.001; 4-8 h, 8-12 h, 24 h; total P < 0.001). The incidence of chronic pain was 11%, and there was no statistically significant difference between control and SPB groups in terms of SF-36, NRS, and painDETECT scores measured at the first and sixth months. CONCLUSIONS: SPB demonstrated superiority versus the control group concerning acute postoperative pain parameters. However, SPB had no influence on the quality of life and did not prevent chronic postmastectomy pain.
