Mechanical ventilation in foals with botulism: 9 cases (1989-2002).

The research article discusses the results of a study where early mechanical ventilation was used as part of the treatment for foals with toxicoinfectious botulism. The study showed promising results with an 87.5% survival rate.

Introduction to Botulism in Foals

• The study focuses on “shaker foal” disease or toxicoinfectious botulism. This condition was first identified in 1967, primarily affecting infant horses. The mortality rate associated with this disease was about 90%, with most affected foals dying within 24 to 72 hours of showing symptoms.
• The treatment scenario improved once an equine-origin botulism antitoxin was introduced in medical practices. However, some foals still succumbed to the disease, particularly due to respiratory failure.

Scope of the Study

• The research conducted involves a retrospective study of nine foals who were suffering from botulism and were treated using early mechanical ventilation along with other therapies.
• The response of the animals to the treatment and their eventual health outcome was the primary concern of this study.

Findings of the Study

• The paper reports that the foals presented with progressive acidemia and increased PaCO2 tensions before mechanical ventilation was administered.
• These arterial blood gas abnormalities were rectified by the mechanical ventilation treatment.
• One of the foals in the study had to be euthanized due to financial constraints, but otherwise, the survival rate was high at 87.5%.

Conclusion

• Based on the observations, the authors concluded that early mechanical ventilation appears to be an effective therapy for treating respiratory failure in foals suffering from botulism.
