Detaljert beskrivelse
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.

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.
|
Kontinuerlig intraoperativ overvåkning av narkosedybde ved bruk av Bispectral Index (BIS)-enheten.
BIS-verdier registreres gjennom hele prosedyren for å hjelpe til med dosering av narkosemidler og for å standardisere narkosedybde på tvers av studiekohortene.
BIS-enheten brukes kun til overvåkning, og ingen enhetsrelaterte undersøkelsesprosedyrer utføres.
Andre navn:
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.
