Topic:Emergency Care
Emergency care in horses involves the immediate assessment and treatment of acute medical conditions or injuries to stabilize the animal and prevent further harm. This area of veterinary practice encompasses a range of situations, including colic, traumatic injuries, respiratory distress, and sudden lameness. Emergency care procedures may involve physical examinations, diagnostic imaging, fluid therapy, pain management, and, in some cases, surgical intervention. This topic includes peer-reviewed research studies and scholarly articles that explore the methods, protocols, and outcomes associated with emergency interventions in equine medicine.
Traumatic Ventricular Septal Defect Caused by a Horse Kick Injury: 2 Rare Pediatric Cases. We present 2 cases of traumatic ventricular septal defects (VSDs), both caused by horse kick injuries. Given this rare but critical condition, we decided to share our experiences and the lessons learned managing these cases. Methods: The first patient, a 12-year-old girl, was trampled by a horse, sustained a traumatic apical ventricular septal defect with pseudoaneurysm, was stabilized first, and underwent surgical closure 19 days after the injury. The second patient, a 9-year-old girl, was kicked by a horse in the chest; developed profound cardiogenic shock; and was found to have multiple lar...
Horse owners seeking online health information: a mixed-methods study. Many people seek health-related information online, not only for themselves but also on behalf of others who cannot articulate their symptoms. This proxy information-seeking behavior is particularly relevant for animal owners, who must interpret their animals' symptoms without direct verbal feedback. While online health information-seeking in the context of one's own health is well-studied, the specific challenges of searching by proxy, especially for animal health information, remain largely unexplored. Unassigned: This study aimed to determine the specific information needs and search behavi...
