Fluid retention after shoulder arthroscopy: gravity flow vs. automated pump-a prospective randomized study.

Area of Science:

• Orthopedic Surgery
• Minimally Invasive Procedures
• Fluid Management in Surgery

Background:

• Soft tissue fluid retention is a common complication following shoulder arthroscopy.
• Irrigation systems are essential for visualization during arthroscopic procedures.
• Comparing different irrigation methods is crucial for optimizing patient outcomes.

Purpose of the Study:

• To compare fluid retention between gravity flow irrigation (GFS) and automated pump system (APS) during shoulder arthroscopy.
• To evaluate the impact of irrigation systems on periarticular fluid accumulation.
• To assess secondary outcomes like deltoid diameter changes and postoperative pain.

Main Methods:

• Prospective randomized study involving patients undergoing shoulder arthroscopy.
• Patients were assigned to either GFS or APS for irrigation.
• Net weight gain served as the primary outcome for fluid retention assessment.

Main Results:

• The automated pump system (APS) group exhibited greater weight gain per hour (1.46 kg/h) compared to the gravity flow system (GFS) group (1.1 kg/h).
• A significant correlation was observed between irrigation fluid volume and weight gain in both groups.
• The APS group showed a larger increase in deltoid diameter and higher initial postoperative pain scores.

Conclusions:

• Automated pump systems lead to increased fluid retention in shoulder arthroscopy compared to gravity flow systems.
• Factors contributing to fluid retention include the use of APS, prolonged surgical duration, and larger volumes of irrigation fluid.
• Optimizing irrigation strategies is important for minimizing postoperative complications.
