Brief Summary

Shoulder arthroscopy offers numerous advantages and has led to a continuous increase in procedural complexity. Adequate intraoperative visual clarity is essential for successful performance of the procedure and is primarily dependent on effective hemorrhage control.The aim of this prospective, double-blind, randomized controlled study is to evaluate the effect of intravenously administered tranexamic acid (TXA) on intraoperative visual clarity, perioperative blood loss, procedure duration, and early postoperative outcomes in patients undergoing shoulder arthroscopy in the beach chair position, an area for which limited data are currently available in the literature. In both the experimental and control groups, hemoglobin levels are measured in the irrigation fluid and in patients' blood samples obtained before and after surgery. Additional outcomes include intraoperative visual clarity, duration of the procedure, postoperative shoulder swelling, postoperative pain intensity, and analgesic consumption.This study applies established scientific methods to determine whether there is a justified basis for the introduction of TXA into routine clinical practice for shoulder arthroscopy.

Outcome Measures

Primary Outcomes (1)

  • Visual Clarity on Endoscope Screen During Shoulder Arthroscopy (Intraoperative)

    The operating surgeon evaluated intraoperative visual clarity using the Visual Analog Scale for visibility (VAS-V), ranging from 0 (worst visual clarity) to 10 (best visual clarity), at 15-minute intervals during shoulder arthroscopy. At each assessment time point, the endoscope screen was simultaneously photographed. The surgeon was blinded to group allocation. Visual clarity assessments performed from skin incision up to 135 minutes of surgery were included in the analysis. For each participant, all intraoperative VAS-V measurements within this period were averaged to obtain a single mean intraoperative visibility score. Higher scores indicate better visual clarity.

    From skin incision to final suture (intraoperative period), assessed every 15 minutes, up to 135 minutes

Secondary Outcomes (16)

  • Independent Assessor Visibility Rating (VAS)

    From skin incision to final suture (intraoperative period), up to 135 minutes; image assessments performed after completion of surgery

  • Interobserver Agreement of Independent Assessors for Arthroscopic Visibility Ratings (VAS)

    After completion of surgery, following blinded assessment of standardized intraoperative arthroscopic images obtained from skin incision to final suture.

  • Comparison of Arthroscopic Visibility Ratings Between the Operating Surgeon and Independent Assessors (VAS)

    From skin incision to final suture (intraoperative period), assessed every 15 minutes, up to 135 minutes; independent image evaluations performed after completion of surgery

  • Concentration of Hemoglobin in Waste Irrigation Fluid (mg/100 mL)

    From skin incision to final suture (intraoperative period)

  • Number of Irrigation Pump Pressure-boost Events

    From skin incision to final suture (intraoperative period)

  • +11 more secondary outcomes

Limitations and Caveats

The trial was registered after initiation of enrollment. Adverse events were not systematically collected and were recorded only if they occurred during the perioperative hospital stay. Intraoperative visual clarity assessment was subjective; however, it was supported by objective hemoglobin measurements in irrigation fluid and by independent evaluation of intraoperative images by three blinded expert assessors. The study was conducted at a single center.
