Surgical resolution of accidental intramuscular injection of Gudair® vaccine in a mare.

The research article presents a case study on the treatment of a horse that received an accidental intramuscular injection of Gudair® vaccine. The horse was successfully treated through surgical resection to address the resulting inflammation.

Introduction and Case Presentation

• This research paper documents a unique case where a Standardbred mare, aged 7, was accidentally administered an intramuscular injection of 20 mL Gudair® vaccine, which is usually used to prevent tuberculosis in goats and sheep.
• Normally, Gudair® is not used in horses, and this unintended treatment initiated an inflammatory reaction in the animal.

Treatment and Outcome

• To counteract this inflammatory reaction, the authors of the study employed a radical surgical resection approach. This involved removing the inflamed tissue surgically.
• The treatment was administered promptly once the error in vaccine administration was recognized, and it was followed by a suitable recovery period and healthcare management for the mare.

Significance and Conclusion

• The fact that the treatment was successful is of utmost significance, implying that radical surgical resection could be a feasible treatment strategy in similar future cases.
• Though not typical, misadministration of vaccines can occur in large animals. This case study provides veterinarians with an example of how to handle such cases with an effective treatment strategy.
• The paper thus adds to the body of knowledge on managing complications of unintended intramuscular injections in horses.
