Mastectomy and Axillary Dissection: Evaluation of the Effect of Serratus Posterior Superior Intercostal Plane Block on Postoperative Analgesia: A Multicenter, Randomized, Placebo-Controlled Trial

This study aims to evaluate the effect of serratus posterior superior intercostal plane (SPSIP) block on postoperative pain, opioid consumption, and analgesic requirements in patients undergoing mastectomy and axillary lymph node dissection

详细说明

This study is a prospective, randomized, placebo-controlled, multicenter clinical trial designed to evaluate the analgesic efficacy of the serratus posterior superior intercostal plane (SPSIP) block in patients undergoing mastectomy with axillary lymph node dissection. Postoperative pain following breast surgery is often significant and may increase opioid consumption and related adverse effects, highlighting the need for effective regional anesthesia techniques.

The SPSIP block is a novel ultrasound-guided interfascial plane block with emerging evidence in thoracic and chest wall procedures; however, its role in breast surgery remains unclear, particularly in placebo-controlled settings. This study aims to determine whether the SPSIP block provides additional benefit as part of a standardized multimodal analgesia approach.

Participants will be randomly assigned to receive either SPSIP block with local anesthetic or a placebo intervention under identical conditions, with blinding applied to all relevant parties. All patients will receive the same perioperative anesthesia and analgesia protocol.

The results of this study are expected to clarify the clinical value of SPSIP block in breast surgery and contribute to the development of evidence-based postoperative pain management strategies.

大体时间：24 hours
Total opioid consumption within the first 24 hours after surgery, recorded in milligrams.
24 hours

次要结果测量

结果测量
措施说明
大体时间
Static postoperative pain intensity at rest
大体时间：0, 1, 2, 6, 12, and 24 hours after surgery
Postoperative pain intensity at rest will be assessed using the Numeric Rating Scale (NRS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
0, 1, 2, 6, 12, and 24 hours after surgery
Dynamic postoperative pain intensity during movement
大体时间：0, 1, 2, 6, 12, and 24 hours after surgery
Postoperative pain intensity during movement will be assessed using the Numeric Rating Scale (NRS), ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
0, 1, 2, 6, 12, and 24 hours after surgery
Rescue analgesia requirement
大体时间：Within 24 hours after surgery
Number of patients requiring rescue analgesia and total rescue analgesic consumption.
Within 24 hours after surgery
Time to first rescue analgesia
大体时间：Within 24 hours after surgery
Time from the end of surgery to the first administration of rescue analgesia.
Within 24 hours after surgery
Incidence of postoperative nausea and vomiting (PONV)
大体时间：Within 24 hours after surgery
Occurrence of nausea and/or vomiting during the postoperative period.
Within 24 hours after surgery
Block-related and opioid-related adverse events
大体时间：Within 24 hours after surgery
Incidence of adverse events including local anesthetic toxicity, hematoma, infection, and opioid-related side effects.
Within 24 hours after surgery
Quality of Recovery-15 (QoR-15) score
大体时间：24 hours after surgery
Quality of recovery assessed using the QoR-15 questionnaire. Quality of Recovery-15 (QoR-15) questionnaire was used to assess postoperative recovery. The total score ranges from a minimum of 0 to a maximum of 150. A higher score represents a better recovery outcome (0 = extremely poor recovery, 150 = excellent recovery)
24 hours after surgery
