ABSTRACT

BACKGROUND: Peritoneal fluid analysis has both diagnostic and prognostic value in colic but is little reported in the post-partum mare. Multiple conditions may present similarly in this period, and peritoneal fluid findings may aid a prompt diagnosis. OBJECTIVES: To describe the peritoneal fluid findings and their association with diagnosis in mares presenting to a single referral hospital for treatment of post-partum emergencies. STUDY DESIGN: A retrospective clinical study. METHODS: Clinical records of 110 Thoroughbred mares were reviewed. Details of peritoneal fluid analysis from samples obtained at admission were recorded, in addition to history, physical examination, presenting clinicopathological data. Cases were classified by their primary diagnosis into groups of gastrointestinal tract (GIT), urogenital trauma (UGT) and post parturient haemorrhage (PPH). Univariable analysis was performed to compare findings between groups, using one-way ANOVA and post hoc Tukey/Kruskal-Wallis, as appropriate. A multinomial logistic regression was performed for variables significant in the univariable analysis. RESULTS: When separated into their diagnostic categories, 33/110 (30%) mares were classified as GIT, 55/110 (50%) UGT and 22/110 (20%) PPH. Peritoneal fluid packed cell volume (PCV), nucleated cell count (WBCC) and cytological findings were significantly different between diagnostic categories. The likelihood of diagnosis of PPH increased with an increase in peritoneal fluid PCV, the absence of degenerate neutrophils on peritoneal fluid cytology and a decrease in the peritoneal fluid WBCC. Overall survival to discharge was 55%. MAIN LIMITATIONS: The study is referral hospital-based and retrospective in nature. Missing data reduced the power of analysis for several variables. CONCLUSIONS: Peritoneal fluid analysis may guide diagnosis in post-partum emergencies, but no one factor is uniformly diagnostic. Mares with PPH presented with a non-septic peritonitis with higher peritoneal PCV.

ABSTRACT

BACKGROUND: There is little consensus on factors associated with survival in foals with septic arthritis and limited data on long-term racing performance of Thoroughbred foals treated for septic arthritis. A more thorough understanding of short- and long-term outcome is necessary to help inform owners, and subsequently guide treatment. OBJECTIVES: To investigate factors associated with survival, and to analyse racing performance of foals with septic arthritis compared with their maternal siblings. STUDY DESIGN: Retrospective cohort and a case-control study. METHODS: Veterinary clinical records of Thoroughbred foals ≤180 days old that underwent arthroscopic, cannulae or through-and-through needle lavage for the treatment of septic arthritis between 2009 and 2015 were reviewed. Data included signalment, and clinicopathological information. The dam's foaling records were reviewed and the lifetime racing records were obtained for affected foals and two of their maternal siblings. Logistic regression analysis was used to determine factors associated with survival to discharge or racing. Comparisons between treated foals and their maternal siblings were made. RESULTS: Ninety (78%) of 115 foals diagnosed with septic arthritis were discharged alive. Foals <26 days old at the time of admission were five times less likely (P = .003) and foals with concurrent multisystemic disease were six times less likely (P = .02) to be discharged alive. Sixty (67%) foals discharged alive started in ≥1 race, and there was no difference in the proportion of foals that started in a race or racing performance between foals treated for septic arthritis and their maternal siblings. MAIN LIMITATIONS: Retrospective study design, limited number of foals with multiple joint involvement and failure to accurately record duration of clinical signs. CONCLUSIONS: Foals treated for septic arthritis at the Scone Equine Hospital, New South Wales, Australia had a good prognosis for survival, and for this cohort, foals that survived to discharge had a similar ability to race as their maternal siblings.

ABSTRACT

Assessment of peripheral blood leukocytes is the most common clinical pathology test in equine practice. It is always a part of complete body function assessment and frequently is used alone, or in conjunction with, fibrinogen to monitor response to treatment.
