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.

Presence of new mecA and mph(C) variants conferring antibiotic resistance in Staphylococcus spp. isolated from the skin of horses before and after clinic admission. Because of the frequency of multiple antibiotic resistance, Staphylococcus species often represent a challenge in incisional infections of horses undergoing colic surgery. To investigate the evolution of antibiotic resistance patterns before and after preventative peri- and postoperative penicillin treatment, staphylococci were isolated from skin and wound samples at different times during hospitalization. Most staphylococci were normal skin commensals and belonged to the common coagulase-negative group. In some cases they turned out to be opportunistic pathogens present in wound infections. M...

Placement of a long term tracheal cannula in a Thoroughbred racehorse with bilateral laryngeal dysfunction. A Thoroughbred horse with bilateral laryngeal dysfunction was treated by placement of a long term tracheal cannula in order to restore full athletic function. The horse initially presented with right-sided arytenoid dysfunction that was considered to be due to a congenital malformation of the laryngeal cartilage. This was corrected by a right-sided laryngoplasty and ventriculectomy. The horse re-presented 1 year later with idiopathic left laryngeal hemiplegia. The decision was made to place a long-term tracheal cannula due to the low success rate and high complication rate associated with othe...
Surgical treatment of extensive chondroid formation in the guttural pouch of a Warmblood horse. A Warmblood horse presented with a purulent nasal discharge that had failed to respond to antibiotic therapy. Radiography and endoscopy confirmed a large number of chondroid masses (over 200) in the left guttural pouch. Despite the large number of chondroids present, there was no external swelling evident. The masses were surgically removed via a hyovertebrotomy approach that provided excellent exposure, and no postoperative complications were encountered. Long term follow-up (3 years) confirmed a successful outcome.
Prevention of postoperative infections in horses. The best defense against postoperative infection is to use multiple strategies to minimize wound contamination, maintain wound tissue health, and provide rational antimicrobial strategies that do not promote the development of resistant bacteria and superinfections.
