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.
Laparoscopic techniques for investigating the equine oviduct. The diagnostic and therapeutic options for oviduct disorders in the mare are limited. The current best techniques require exploratory surgery under general anaesthesia or flank laparotomy. Objective: The orthograde flushing of the oviduct for diagnostic or therapeutic options is possible using laparoscopic techniques in the standing sedated mare. Methods: Development of a laparoscopic technique for catheterisation of the infundibulum and flushing of the oviduct (sterile methylene blue solution) in the standing sedated mare was examined in 2 experiments. The first involved a transvaginal laparo...
Arthroscopic removal of fractures of the lateral malleolus of the tibia in the tarsocrural joint: a retrospective study of 13 cases.

Objective: To determine if: 1) there was a difference in size or configuration of apical fractures between the different anatomical locations of the PSBs, which have been shown to affect the prognosis; and 2) the size or configuration could predict the prognosis for racehorses with these fractures. Methods: The study included 110 weanlings and yearlings and 56 training racehorses that underwent surgery to remove apical ...
Clinical application and reliability of a post abdominal surgery pain assessment scale (PASPAS) in horses. The aim of this study was to refine a multi-dimensional scale based on physiological and behavioural parameters, known as the post abdominal surgery pain assessment scale (PASPAS), to quantify pain after laparotomy in horses. After a short introduction, eight observers used the scale to assess eight horses at multiple time points after laparotomy. In addition, a single observer was used to test the correlation of each parameter with the total pain index in 34 patients, and the effect of general anaesthesia on PASPAS was investigated in a control group of eight horses. Inter-observer variabilit...

Horses with paraphimosis had been medically treated without success. The horse with priapism had developed the condition secondary to acepromazine administration 2 days prior to referral ...
[The extent of temperature sense and pain appreciation recovery in the dermatomes of cauda equine roots after lumbar intervertebral dischernia elimination]. Temperature sense and pain appreciation has been studied in the dermatomes of cauda equine roots in patients with lumbar intervertebral disc hernia before treatment, in the immediate and long-term periods of observation after disc hernia elimination. Temperature sense and pain appreciation has been determined to be disordered not only in the dermatome of compressed root, but in the dermatomes located proximally and distally as well. The manifestation of negative changes was observed to a greater extent during temperature sense examination. After disc hernia elimination the recovery of temperat...

Of the remaining 52 mares, seasonal pregnancy and live foaling rates were 67% (35/52) and 54% (26/48), respectively. When mares were bred in the same cycle as the surgery, the first cycle following surgery...
Difference in incisional complications following exploratory celiotomies using antibacterial-coated suture material for subcutaneous closure: Prospective randomised study in 100 horses. Incisional complications are a major post operative challenge following ventral midline exploratory celiotomy for abdominal pain in horses. They lead to discomfort, prolonged hospitalisation, longer recovery times and increased cost; therefore, investigation of preventative procedures are warranted. Objective: To determine the clinical effect of antibacterial (triclosan) coated 2-0 polyglactin 910 suture material on the likelihood of incisional infections when used for closure of subcutaneous tissue following ventral midline celiotomies in horses. Methods: One hundred horses undergoing explora...
