Veterinary surgeons show significant disagreement in naming common surgical friction knots, leading to potential communication barriers. Consistent terminology is crucial for effective surgical education and practice.
Area of Science:
- Veterinary Surgery
- Surgical Techniques
- Medical Education
Background:
- Friction knots are essential in veterinary surgical procedures.
- Standardized nomenclature for surgical knots is important for clear communication and education.
- Previous studies have not definitively established consensus on friction knot terminology in veterinary medicine.
Purpose of the Study:
- To investigate and determine the common nomenclature used for friction knots among veterinary surgeons.
- To identify areas of consensus and disagreement in the naming of specific surgical friction knots.
- To assess the familiarity of veterinary surgeons with commonly used friction knots.
Main Methods:
- A survey was distributed to veterinary surgeons certified by the American College of Veterinary Surgeons (ACVS) and the European College of Veterinary Surgeons (ECVS).
- Participants were asked to identify 4 friction knots presented in video format.
- Data from 160 complete responses were analyzed to determine knot familiarity and naming accuracy.
Main Results:
- Familiarity with surgical friction knots varied, with the constrictor knot known by 26% and the miller's knot by 54% of respondents.
- A majority correctly identified the modified miller's knot (61%) and miller's knot (63%).
- No consensus was reached for the constrictor knot (38% named it correctly) or the strangle knot (21% named it correctly), indicating significant naming discrepancies.
Conclusions:
- There is apparent disagreement and lack of consensus on the nomenclature of surgical friction knots among veterinary surgeons.
- Inconsistent terminology for surgical knots may hinder educational efforts and clear communication within the veterinary surgical community.
- Further standardization of knot terminology is recommended to improve surgical training and practice.
