Curious about the scientific evidence behind treating joint infections in foals? This eye-opening conversation with Dr. David Wallace explores groundbreaking research validating common clinical practices while revealing surprising limitations.

Septic joints in foals present a clinical challenge requiring both local and systemic antimicrobial therapy. Until now, veterinarians have largely extrapolated treatment protocols from adult horses without solid evidence supporting these approaches in neonatal patients. Dr. Wallace's research addresses this critical knowledge gap, examining whether concurrent intravenous regional limb perfusion (IRLP) and systemic amikacin administration achieves therapeutic concentrations in both compartments.

The results offer reassurance that splitting the amikacin dose—one-third for regional perfusion and two-thirds systemically—effectively treats both joint infections and underlying systemic disease. Most joints achieved therapeutic concentrations, though significant challenges emerged with hind limb perfusions. The metatarsophalangeal joint consistently failed to reach target levels, revealing important technical limitations around tourniquet placement and vascular integrity that clinicians should consider when treating these patients.

This conversation highlights numerous opportunities for future research, from evaluating alternative tourniquet designs to determining appropriate dose adjustments for multiple affected limbs. Dr. Wallace emphasizes that individual patient response remains paramount, reminding us that "foals are not small horses" and require specialized approaches. Whether you're a practicing veterinarian, student, or equine enthusiast, this episode provides valuable insights into evidence-based care for our youngest equine patients.

A groundbreaking approach to equine intestinal motility takes center stage as Drs. Barbara Delvescovo and Marta Cercone join us to discuss their pioneering research on ultrasound-guided celiac plexus blocks in horses. Their remarkable findings reveal that this technique not only restores but actually enhances intestinal motility beyond baseline levels in normal horses—without causing discomfort.

Post-operative ileus remains one of the most challenging conditions in equine medicine, significantly increasing mortality rates after colic surgery. Traditional treatments often fall short, requiring a multimodal approach with limited options. This innovative nerve block technique offers a promising new tool that equine practitioners with basic ultrasound skills can implement in their practice.

The conversation takes fascinating turns as we explore the researchers' diverse backgrounds, from Marta's long-standing interest in neuromodulation to Barbara's clinical practice insights. Their journey reveals how mentorship and curiosity drive scientific discovery, perfectly captured in Marta's guiding principle: "True knowledge exists in knowing that you know nothing." They also share encouraging news for horse owners—contrary to common belief, many horses return to full athletic performance after colic surgery with modern management techniques. The team is now extending their research to clinical cases and inflammatory conditions, potentially transforming how we approach equine gastrointestinal disorders. For veterinarians seeking innovative solutions to challenging cases, this episode offers valuable insights into the intersection of regional anesthesia, ultrasonography, and equine medicine.

When your pet needs ear surgery, their eyes might be the last thing on your mind. Yet Dr. Bianca Hartrum's pioneering research reveals a critical connection between ear procedures and vision health that veterinary professionals and pet owners can no longer afford to ignore.

Dr. Hartrum's study examines ocular examinations before and after total ear canal ablation and bulla osteotomy (TECALBO) procedures in cats and dogs. The findings are striking: a staggering 90.9% of cats developed Horner's syndrome following surgery—far higher than previously documented rates. Additionally, 20% of patients already had eye disease related to their ear condition before surgery, while another 30% had unrelated ocular issues discovered during comprehensive exams.

The research originated from a troubling case early in Dr. Hartrum's residency—a dog with a severe melting corneal ulcer and facial nerve paralysis following ear surgery. This prompted her deep dive into existing literature, where she found only passing mentions of neuro-ophthalmic complications without detailed analysis. Her study fills this critical knowledge gap with ophthalmologic expertise and data-driven recommendations that are already transforming clinical practice.

The take-home message is clear and actionable: thorough eye examinations should be standard before and after ear surgeries. Dr. Hartrum recommends Schirmer tear tests, fluorescein staining, and post-operative topical lubricants as minimum protective measures. These simple steps can prevent potentially devastating vision complications. These findings can lead to new collaborative care protocols incorporating pre- and post-operative eye exams into surgical costs.

Has your veterinarian discussed potential eye complications before your pet's ear surgery? Share your experience and help spread awareness about this important connection between ear and eye health in our beloved companions.
