Overview

The aim is to compare the postoperative analgesic efficacy of serratus anterior plane block (SAPB) and serratus posterior superior intercostal plane block (SPSIPB) in patients undergoing mammoplasty surgery. To this end, a double-blind, randomized, controlled study has been designed. Female patients aged 18-65 years who will undergo mammoplasty surgery will be included in the study. Postoperative pain levels, opioid consumption, duration of analgesic requirement, and patient satisfaction will be evaluated in patients who receive fascial blocks for analgesic purposes.

Pain management after breast surgery plays an important role in the patients' recovery process. Therefore, investigating effective and safe analgesic methods is important for improving patient comfort in the postoperative period. The serratus anterior plane block (SAPB) is a regional anesthesia technique commonly used for pain control after breast surgery. SAPB has been shown to be effective in reducing postoperative pain and decreasing opioid consumption. In addition, SAPB is easy to perform and has a low risk of complications. The serratus posterior superior intercostal plane block (SPSIPB) is a new technique developed to provide analgesia in thoracic surgeries. SPSIPB has been reported to be effective in reducing postoperative pain and decreasing analgesic consumption. However, data on the efficacy of SPSIPB in breast surgery are limited. This study aims to compare the postoperative analgesic efficacy of SAPB and SPSIPB in patients undergoing mammoplasty. For this purpose, a double-blind, randomized, controlled trial has been designed.

Interventions

Serratus Anterior Plane BlockPROCEDURE

Application of ultrasound-guided serratus anterior plane block for perioperative analgesia for mammoplasty operations. Serratus anterior plane block will be administered under general anesthesia before the surgery Drug: Bupivacaine (Block Drug) For block performances, 0,25% Bupivacaine will be used at 0,5 ml/kg (max. 20cc) for each side.

Serratus Posterior Superior Intercostal Plane BlockPROCEDURE

Application of ultrasound-guided serratus anterior plane block for perioperative analgesia for mammoplasty operations. Serratus posterior superior intercostal plane block will be administered under general anesthesia before the surgery Drug: Bupivacaine (Block Drug) For block performances, 0,25% Bupivacaine will be used at 0,5 ml/kg (max. 20cc) for each side.

Outcomes

Primary Outcomes

Total opioid consumption

Tramadol will be prepared at a concentration of 10 mg/mL, and patient-controlled analgesia (PCA) will be administered without a basal infusion, using a lock-out interval of 20 minutes and a bolus dose of 20 mg.

Time frame: 0, 1, 6, 12 and 24 hours

Postoperative pain scores (Numerical rating scale: NRS),Between 0 and 10 points (11 points in total), as the score increases, the pain intensity increases.

Postoperative 24 hours period. Patients' pain scores will be questioned at 0, 1, 6, 12 and 24 hours.

Time frame: 0, 1, 6, 12 and 24 hours

Secondary Outcomes

Time to first analgesic requirement

Time from end of surgery to first analgesic requirement (min)

Time frame: 24 Hour

Patient satisfaction score

Overall patient satisfaction scores will be assessed using a 5-point Likert scale,Minimum value: 1, Maximum value: 5, where higher scores indicate greater satisfaction.
