NCT07233681

Brief Summary

The aim to compare postoperative analgesic requirements between patients undergoing arthroscopic shoulder surgery who received either the SSB-ICB combination or SPSIPB, and to determine whether one technique has superiority over the other.

Outcome Measures

Primary Outcomes (2)

  • Numeric Rating Scale (NRS)

    Numeric Rating Scale (NRS): The patient selects a number between 0, representing "no pain," and 10 or 100, representing "unbearable pain." This method is highly sensitive and is one of the most commonly used pain scoring tools.

    24 hours after surgery

  • Total tramadol consumption

    Total postoperative analgesic (tramadol) requirement was recorded in the unit as "milligrams".

    24 hours after surgery

Secondary Outcomes (2)

  • Diaphragm Excursion Difference

    Preoperatively, immediately before anesthesia induction, and postoperatively, 30 minutes after emergence from anesthesia (when a modified Aldrete score of 9 is reached)

  • Quality of Recovery-15 Patient Questionnaire (QoR-15)

    24th hour after surgery

Study Arms (2)

Combination of SSB and ICB

ACTIVE COMPARATOR

Immediately after anesthesia induction, anterior suprascapular nerve block (SSB) and infraclavicular brachial plexus block (ICB) will be performed on the ipsilateral side with the patient supine. For ICB, a high-frequency linear ultrasound probe is placed sagittally over the lateral infraclavicular fossa, medial to the coracoid process and caudal to the clavicle. The needle is inserted below the clavicle, directed cephalad-to-caudal through the pectoralis major and minor toward the posterior aspect of the axillary artery, and 15 mL of 0.25% bupivacaine is injected. For SSB, the probe is positioned over the supraclavicular fossa in a sagittal oblique plane to visualize the subclavian artery and brachial plexus. The suprascapular nerve is identified beneath the omohyoid muscle, the needle is advanced in-plane from lateral to medial, and 10 mL of 0.25% bupivacaine is administered.

Procedure: suprascapular nerve block

SPSIPB

ACTIVE COMPARATOR

The ultrasound probe was placed 2-3 cm medial to the scapular spine to visualize the trapezius, rhomboid major, and serratus posterior superior muscles. At the level of the 2nd-3rd ribs, a needle was advanced into the plane between the serratus posterior superior muscle and the ribs. After confirming negative aspiration, 30 mL of 0.25% bupivacaine was injected. The block was performed unilaterally, targeting the shoulder undergoing surgery.

Procedure: Serratus posterior superior intercostal plane block

Interventions

Suprascapular nerve block (SSB): 10ml of 0.25% bupivacaine was injected around the suprascapular nerve beneath the omohyoid muscle. Infraclavikular nerve block(ICB): The needle is inserted below the clavicle, directed cephalad-to-caudal through the pectoralis major and minor toward the posterior aspect of the axillary artery, and 15 mL of 0.25% bupivacaine is injected

Combination of SSB and ICB

Serratus posterior superior intercostal plane block (SPSIPB): 30 ml of 0.25% bupivacaine was injected into the plane between the serratus posterior superior muscle and the ribs.

SPSIPB
