SPSIPB Versus SAPB for Postoperative Analgesia After Minimally Invasive Repair of Pectus Excavatum

6 luglio 2026 aggiornato da: Ulgen Zengin, Marmara University

Comparison of the Postoperative Analgesic Effects of Serratus Posterior Superior Intercostal Plane Block and Serratus Anterior Plane Block After Minimally Invasive Repair of Pectus Excavatum: A Prospective Observational Cohort Study

This prospective observational cohort study will compare postoperative analgesic outcomes in patients undergoing minimally invasive repair of pectus excavatum. Participants will be grouped according to the regional analgesia technique applied as part of routine clinical care: serratus posterior superior intercostal plane block or serratus anterior plane block. The primary outcome will be total opioid consumption during the first 24 hours after surgery. Secondary outcomes will include postoperative pain scores, rescue analgesic requirement, opioid-related adverse effects, patient satisfaction, mobilization time, and length of hospital stay.

Panoramica dello studio

Descrizione dettagliata

Pectus excavatum is the most common chest wall deformity in pediatric and adolescent patients and is characterized by posterior depression of the sternum and anterior chest wall. Although many patients are asymptomatic, corrective surgery is frequently performed during adolescence or young adulthood for cosmetic reasons and to improve body image and quality of life.

Minimally invasive repair of pectus excavatum involves the placement of a curved metal bar beneath the sternum. The bar is then rotated to elevate the sternum and correct the chest wall deformity. Despite favorable cosmetic and quality-of-life outcomes, postoperative pain remains a major clinical challenge after this procedure. Pain is mainly related to sternal elevation, pressure exerted by the bar, and repositioning of the ribs. Inadequate pain control may increase opioid consumption and prolong hospitalization. Higher opioid exposure may also lead to adverse effects such as nausea, vomiting, constipation, pruritus, and urinary retention.

Regional anesthesia techniques have become important components of multimodal postoperative analgesia in thoracic surgery. Thoracic paravertebral block, erector spinae plane block, and serratus anterior plane block are among the regional techniques commonly used for thoracic analgesia. Serratus anterior plane block has also been used for postoperative pain management after minimally invasive repair of pectus excavatum.

Serratus posterior superior intercostal plane block is a recently described ultrasound-guided interfascial plane block. The technique involves injection of local anesthetic between the serratus posterior superior muscle and the rib, usually at the level of the second or third rib. This block has been reported to provide analgesia in various thoracic and scapular pain conditions and has shown promising results in thoracic surgery.

The aim of this study is to compare the postoperative analgesic outcomes of serratus posterior superior intercostal plane block and serratus anterior plane block in patients undergoing minimally invasive repair of pectus excavatum. Because this is an observational study, the choice of regional analgesia technique will not be determined by the study protocol. The block technique will be selected by the attending anesthesiologist according to routine clinical practice. No randomization or protocol-driven assignment will be performed.

Coorti e interventi

Gruppo / Coorte
Intervento / Trattamento
Serratus Anterior Plane Block Group
Participants in this cohort will receive bilateral ultrasound-guided serratus anterior plane block as part of routine perioperative analgesic care.
Monitoraggio continuo intraoperatorio della profondità dell'anestesia utilizzando il dispositivo dell'indice bispectral (BIS). I valori BIS vengono registrati durante tutta la procedura per assistere nella titolazione degli agenti anestetici e per standardizzare la profondità dell'anestesia tra le coorti dello studio. Il dispositivo BIS viene utilizzato solo per il monitoraggio e non vengono eseguite procedure di indagine correlate al dispositivo.

  • Monitoraggio BRI

All participants will receive a standardized multimodal postoperative analgesia protocol. Patient-controlled analgesia with intravenous morphine will be used. The device will be programmed to administer 1 mg of intravenous morphine per demand, with a lockout interval of 10 minutes. Paracetamol will be administered as part of routine multimodal analgesia. If adequate analgesia cannot be achieved, 100 mg tramadol will be administered as rescue analgesia according to clinical need.
Bilateral ultrasound-guided serratus anterior plane block will be performed according to standard techniques described in the literature and routinely used in the clinic. Local anesthetic dosing will be determined according to institutional practice and safety limits. In bilateral applications, the total bupivacaine dose will not exceed 2.5 mg/kg.
