About

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.

Full description

Patients were divided into two randomized groups: Group 1 (SSB+ICB combination group, n=15) and Group 2 (SPSIPB group, n=15). All patients will receive the same standard general anesthesia per hospital protocol. All blocks will be applied with the same ultrasonography and block equipment, and by the same physician. Before the anesthesia induction, ipsilateral diaphragmatic excursion will be measured via Ultrasonography (USG). After the anesthesia induction, patients in Group 1 will receive anterior suprascapular nerve block (SSB) with 10 mL of 0.25% bupivacaine and infraclavicular brachial plexus block (ICB) with 15 mL of 0.25% bupivacaine (with a total volume of 25 mL). Patients in Group 2 will receive serratus posterior superior intercostal plane block (SPSIPB) with 30 mL of 0.25% bupivacaine. All patients will receive Paracetamol 1gr and Dexketoprofen 50mg intravenous (IV) 10 minutes prior to skin closure. After 30 minutes of emergence from anesthesia (upon reaching 9 points on modified Aldrete scoring), ipsilateral diaphragmatic excursion will be assessed again. Pre- and postblock excursion differences will be recorded. Routine analgesic procedure consisting of 3x1gr Paracetamol and 2x50mg Dexketoprofen will be followed postoperatively for 24 hours. Numeric Rating Scale (NRS) will be used to assess postoperative pain on 1st, 6th, 12th, 18th and 24th hours after the surgery. Quality of Recovery-15 Patient Survey will be done both preoperatively for a baseline score, and postoperatively at 24th hour to assess the quality of recovery from the patients' view. Tramadol 50mg IV will be administered as a rescue analgesic for all patients if NRS score is higher than 4. Total Tramadol consumption will be calculated.

Combination of SSB and ICB

Active Comparator group

Description:

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.

Treatment:

Procedure: suprascapular nerve block

SPSIPB

Active Comparator group

Description:

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.

Treatment:

Procedure: Serratus posterior superior intercostal plane block
