About this study

Most patients undergoing arthroscopic shoulder surgery report pain in the postoperative period. Pain management remains a significant concern in patient management, as it affects surgical costs, postoperative mobility, length of hospital stay, patient satisfaction, and surgical outcomes. Multimodal analgesia is recommended for the management of postoperative pain. Regional analgesia is an important component of multimodal analgesia.

The serratus posterior superior intercostal plane (SPSIP) block is a novel regional analgesia technique described in 2023. SPSIP has been reported to provide near-complete sensory blockade in the posterior neck, shoulder, and hemithorax regions.

The main objective of this study is to investigate the effectiveness of SPSIP block in patients undergoing arthroscopic shoulder surgery.

Treatment and study plan

Group SPSIP: Serratus Posterior Superior İntercostal Plane Block (SPSIP)

Procedure

Serratus Posterior Superior İntercostal Plane (SPSIP) Block will be performed before the surgery in seated position, under standard sterilization conditions.A linear ultrasound probe will be placed in the sagittal plane along the medial border of the scapula, and the second and third ribs, relevant muscles, and the pleura will be identified.

The needle will be advanced into the interfascial plane between the serratus posterior superior and intercostal muscles. After confirmation with salin injection , the block will be performed by injecting 30 mL of 0.25% bupivacaine, and the cranio-caudal spread will be visualized under ultrasound.

Primary outcomes

  1. Postoperative 48-Hour PCA Opioid Consumption

    Time frame: Postoperative 0-8, 8-16, 16-24, 24-48 intervals

    Total amount of opioid delivered by the patient-controlled analgesia (PCA) device during the first 48 hours after surgery, recorded in milligrams(mg)

Secondary outcomes

  1. QoR-15 Recovery Score

    Time frame: Postoperative 24th and 48th hours

    The investigators will use the Turkish version of Quality of Recovery (QoR) / QoR-15 questionairre

    PART A How have you been feeling in the last 24 hours? (0 to 10, where: 0 = none of the time [poor] and 10 = all of the time [excellent])

    Able to breathe easily Been able to enjoy food Feeling rested Have had a good sleep Able to look after personal toilet and hygiene unaided Able to communicate with Getting support from hospital doctors and nurses Able to return to work or usual home activities Feeling comfortable and in control Having a feeling of general well-being

    PART B Have you had any of the following in the last 24 hours? (10 to 0, where: 10 = none of the time [excellent] and 0 = all of the time [poor]) Moderate pain Severe pain Nausea or vomiting Feeling worried or anxious Feeling sad or depressed

  2. Dynamic and static NRS scores

    Time frame: 0, 2, 4, 8, 16, 24, and 48 hours postoperatively

    Numeric Rating Scale (NRS) (0-10 0: No pain 10: most pain felt) pain scores at rest or movement at predefined postoperative hours

  3. Total rescue analgesic dose

    Time frame: Postoperative 24th and 48th hours

    Despite the use of patient-controlled analgesia (PCA), if the Numeric Rating Scale (NRS) score is ≥4 at any time point, 0.5 mg/kg intravenous meperidine will be administered as

  4. Time of first request for rescue analgesia,

    Time frame: Postoperative 48-Hours

    Despite the use of patient-controlled analgesia (PCA), if the Numeric Rating Scale (NRS) score is ≥4 at any time point, 0.5 mg/kg intravenous meperidine will be administered. The time will be recorded.

  5. Length of Hospital Stay

    Time frame: the day of surgery, the day of discharge from the hospital

    Number of days spent in hospital after surgery

  6. Block and Opioid-Related Adverse Effects and Complications

    Time frame: Postoperative 48-Hours

    Block- and opioid-related adverse effects and complications, including but not limited to local anesthetic toxicity, hematoma, infection, nerve injury, nausea, vomiting, pruritus, sedation, and respiratory depression, will be recorded

  7. Perioperative Remifentanil infusion dose

    Time frame: Start time: Start of anesthesia administration End time: Termination of anesthesia administration

    The amount of remifentanil administered in micrograms during general anesthesia
