Anderson et al: Application and influence of four drain configurations on fluid dispersal and retrieval in a cadaveric canine wound infusion-retrieval system model
Veterinary Surgery 2, 2025

🔍 Key Findings

  • Study Design: Cadaveric model using four large-breed dogs with 10x10 cm full-thickness wounds at four locations (shoulder, thorax, flank, thigh).
  • Configurations Tested: Diagonal, opposite, parallel, and perpendicular placements of wound infusion catheter and JP drain.
  • Fluid Retrieval:
    • No significant difference by configuration (p = .92) or location (p = .32).
    • Perpendicular configuration had the highest mean retrieval (11.35 mL, 56.8% of instilled volume).
    • Flank location had the lowest retrieval (7.2 mL, 35.9%).
  • Surface Area Coverage:
    • Parallel configuration achieved the highest SA coverage (83.4% ± 11.6%, p < .01).
    • Perpendicular was lowest.
  • Leakage:
    • No difference in leakage between configurations (p = .74) or locations (p = .10).
    • Leakage commonly occurred at drain or catheter entry points (93.8% of wounds).
  • Conclusion: Parallel drain configuration optimized fluid dispersion. Infusion-retrieval systems may allow for topical therapy delivery in closed wounds.

Multiple Choice Questions on this study

In Anderson 2025 et al., on wound drain configurations, what was the rate of leakage observed across all wounds?

A. 25%
B. 40%
C. 65%
D. 93.8%
E. 100%

Answer: 93.8%

Explanation: Leakage occurred in 93.8% of wounds, mostly at entry sites for the drain system.
In Anderson 2025 et al., on wound drain configurations, how many wounds achieved ≥95% surface area coverage?

A. 1 out of 64
B. 4 out of 64
C. 7 out of 64
D. 12 out of 64
E. 19 out of 64

Answer: 7 out of 64

Explanation: Only 7 of 64 wounds achieved near-complete surface area coverage with the infused solution.
In Anderson 2025 et al., on wound drain configurations, which configuration had the highest mean volume of fluid retrieved?

A. Parallel configuration
B. T-intersection configuration
C. Perpendicular configuration
D. Crossed configuration
E. Spiral configuration

Answer: Perpendicular configuration

Explanation: Perpendicular configuration achieved the highest fluid retrieval (11.35 ± 6.1 mL), though differences were not statistically significant.
In Anderson 2025 et al., on wound drain configurations, which configuration achieved the greatest surface area coverage of the wound bed?

A. Crossed configuration
B. T-intersection configuration
C. Parallel configuration
D. Perpendicular configuration
E. Curved configuration

Answer: Parallel configuration

Explanation: Parallel drain configuration had significantly higher mean surface area coverage compared to others (p < .01).
In Anderson 2025 et al., on wound drain configurations, which anatomical location had the highest consistency in fluid retrieval?

A. Flank
B. Axilla
C. Thigh
D. Shoulder
E. Neck

Answer: Thigh

Explanation: Thigh wounds had the most consistent and highest fluid retrieval performance across configurations.
