Projectile dart foreign body in a horse.

This paper presents the case of a 3-year-old pony that was lame due to a dart lodged in its hind limb following tranquilization through a dart syringe, highlighting the risks of using projected syringes.

Case Summary

• The subject of this study was a 3-year-old Welsh pony. The pony was referred for evaluation due to experiencing lameness in the right hind limb.
• The lameness in the animal developed 4 months after it was tranquilized using a dart syringe. This method involves using a projected syringe to administer drugs and is typically used when the handler cannot safely or easily approach the animal.

Diagnosis and Treatment

• Upon examination, it was found that the lameness was caused by a foreign body – the dart from the syringe.
• The dart was lodged in the pony’s hind limb. The continued presence of the dart was responsible for the continued lameness and discomfort experienced by the pony.
• The researchers successfully removed the dart after inducing local anesthesia, which helped to reduce the pain and discomfort experienced by the pony.
• After the dart was removed, there was a notable improvement in the lameness of the animal.

Discussion

• The researchers concluded that the use of projected syringes to administer medication or tranquilizers could pose significant risks.
• The darts used in such syringes can become lodged in the animal’s body and cause ongoing discomfort and health issues.
• This case serves as a reminder that, whenever possible, it is preferable to administer medications or tranquilizers through less invasive techniques.
• It also highlights the importance of thoroughly checking the animal after the use of such a syringe to ensure all components of the dart have been fully removed.

Recommendations

• The study suggests that handlers considering using dart syringes should carefully weigh the potential risks.
• Clients should be adequately informed and advised of these risks before such a method is employed.
