Topic:Post-Operative Period
The post-operative period in horses refers to the timeframe following surgical procedures during which the animal undergoes recovery and rehabilitation. This period involves careful monitoring and management to ensure proper healing and to minimize complications. Key aspects of the post-operative period include pain management, wound care, and the prevention of infections. Horses may require restricted movement, dietary adjustments, and regular veterinary evaluations to assess recovery progress. This page compiles peer-reviewed research studies and scholarly articles that explore the management strategies, physiological responses, and outcomes associated with the post-operative period in equine patients.
A hematogenic pleuropneumonia caused by postoperative septic thrombophlebitis in a Thoroughbred gelding. A 7-year-old Thoroughbred gelding was admitted to Equine Hospital, Korea Racing Association for evaluation and treatment of colic. Based on the size and duration of the large colonic and cecal impaction, a routine ventral midline celiotomy and large colon enterotomy were performed to relieve the impaction. Six days following surgery the gelding exhibited signs of lethargy, fever, inappetence and diarrhea. Eleven days following surgery, the jugular veins showed a marked thrombophlebitis. On the sixteenth day of hospitalization the gelding died suddenly. Upon physical examination, the horse was ...

Complications in laparoscopic surgery. As laparoscopic surgery gains popularity, it becomes crucial to understand complications associated with the procedure. The potential complications of laparoscopy include those related to laparoscopy and those related to the surgical procedure. As new applications for laparoscopic surgery emerge, it is important for the surgeon to become familiar with potential complications.
Dorsally recumbent female equine urogenital endoscopic surgery. The ventral abdominal approach for laparoscopy is versatile. Reported techniques using a ventral approach in the mare include bilateral ovariectomy and granulosa cell tumor removal. Laparoscopic ovariectomy is performed by way of four instrument portals in the caudoventral aspect of the insufflated abdomen. The procedure has several advantages over the traditional approaches of colpotomy and celiotomy, including tension-free closure of all incisions and minimal invasiveness.
Dorsally recumbent urinary endoscopic surgery. Laparoscopic cystotomy is the method of choice for treatment of a cystic calculus in the horse. The main advantage of this procedure over others is the excellent ability to view and gain operative access to the urinary bladder. This article describes the procedure, including techniques, instrumentation, preoperative and postoperative care, and complications.
Dorsally recumbent male equine urogenital endoscopic surgery. Possibly no other development has revolutionized general surgery more dramatically than laparoscopic surgery in human patients. The development of instrumentation suitable for use in horses has allowed the veterinary surgeon to begin to introduce minimally invasive procedures. Clearly, in people, one of the greatest benefits is reduced patient morbidity and earlier return to function. The author's experience with laparoscopic procedures in the horse would tend to reinforce those observations. The most significant obstacle to widespread acceptance of minimally invasive surgery in the horse is p...

Prevention and treatment of gastrointestinal adhesions. As with many aspects of clinical medicine, there is yet to be a single or definitive cure for postoperative adhesion formation. Current methods of prevention target risk factors predisposing horses to adhesion formation. Systemic pharmacologic therapies, such as antimicrobials, nonsteroidal anti-inflammatory drugs, Salmonella antiserum, and hyperimmune plasma, help to reduce abdominal inflammation and minimize the effects of endotoxemia. Intra-abdominal or systemic heparin aids in enhancing peritoneal fibrinolysis. Prokinetic therapy promotes early postoperative return of intestinal motility, ...
