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.

Detailed 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.

Interventions

PROCEDUREsuprascapular nerve block

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

PROCEDURESerratus posterior superior intercostal plane block

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.

Exclusion criteria

* patients who did not give consent, * patients with coagulopathy, * patients with signs of infection at the block application site, * patients using anticoagulants, * patients with local anesthetic drug allergies, * patients with unstable hemodynamics, * patients who could not cooperate during postoperative pain assessment * patients diagnosed with frozen shoulder

Design outcomes

Primary

MeasureTime frameDescription
Numeric Rating Scale (NRS)24 hours after surgeryNumeric 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.
Total tramadol consumption24 hours after surgeryTotal postoperative analgesic (tramadol) requirement was recorded in the unit as milligrams.

Secondary

MeasureTime frameDescription
Diaphragm Excursion DifferencePreoperatively, immediately before anesthesia induction, and postoperatively, 30 minutes after emergence from anesthesia (when a modified Aldrete score of 9 is reached)Ipsilateral diaphragmatic movement will be assessed both immediately before anesthesia induction in the preoperative period and 30 minutes after emergence from anesthesia (when a modified Aldrete score of 9 is reached). A change of up to 25% in diaphragmatic movement indicates no nerve involvement, a change between 25% and 75% indicates partial involvement, and a change exceeding 75% indicates complete phrenic nerve blockade.
Quality of Recovery-15 Patient Questionnaire (QoR-15)24th hour after surgeryThe widespread use of minimally invasive procedures to reduce postoperative morbidity and mortality, combined with the implementation of Enhanced Recovery After Surgery (ERAS) protocols, has increased overall interest in the postoperative recovery period and the assessment of outcomes. To address emerging needs in this field, new tools prioritizing patient satisfaction have been developed alongside traditional scales that measure classic parameters. Among these, the Quality of Recovery-15 (QoR-15) patient questionnaire stands out as one of the most up-to-date and reliable instruments. The questionnaire is administered both preoperatively, to record the patient's baseline, and 24 hours after surgery. Higher scores indicate better postoperative recovery quality, with possible scores ranging from 0 to 150.
