EQUINE Horse racing is a popular, multimillion-dollar industry worldwide, but reports of injuries and other physical disorders in racehorses have harmed public perceptions of the sport and challenged the economic viability of the racing industry. In addition, controversy has been generated by use of medications that are perceived to affect the performance or well-being of racehorses. One of the foremost concerns in this regard is the occurrence of EIPH and the use of medications in an attempt to prevent it. Factors that make this an important issue include the frequency of EIPH, the importance of the disease in terms of the performance and well-being of horses, and the common use of prophylactic treatments. At least 80% of racehorses can be expected to develop the condition at some time during their career, 1,2 approximately 60% of sudden deaths during racing have been attributed to pulmonary hemorrhage, 2 severe EIPH has been shown to adversely affect race performance, 3 and EIPH is believed to adversely affect the overall health of racehorses. 4 Beyond this, Objective-To evaluate the efficacy of furosemide for prevention of exercise-induced pulmonary hemorrhage (EIPH) in Thoroughbred racehorses under typical racing conditions. Design-Randomized, placebo-controlled, blinded, crossover field trial. Animals-167 Thoroughbred racehorses. Procedures-Horses were allocated to race fields of 9 to 16 horses each and raced twice, 1 week apart, with each of the 2 races consisting of the same race field and distance. Each horse received furosemide (500 mg, IV) before one race and a placebo (saline solution) before the other, with the order of treatments randomly determined. Severity of EIPH was scored on a scale from 0 to 4 after each race by means of tracheobronchoscopy. Data were analyzed by means of various methods of multivariable logistic regression.Results-Horses were substantially more likely to develop EIPH (severity score ≥ 1; odds ratio, 3.3 to 4.4) or moderate to severe EIPH (severity score ≥ 2; odds ratio, 6.9 to 11.0) following administration of saline solution than following administration of furosemide. In addition, 81 of the 120 (67.5%) horses that had EIPH after administration of saline solution had a reduction in EIPH severity score of at least 1 when treated with furosemide. Furosemide is the drug most widely used to prevent EIPH in racehorses and is administered on the day of racing to > 92% of Thoroughbred racehorses in North America (approx 400,000 doses/y). 4,5 However, few studies have examined whether furosemide is effective in preventing the development of EIPH, and the studies that have been performed were not conducted Conclusions and Clinical Relevance-Results

“…Sudden death accounted for 26% of all fatalities on Victorian racetracks recorded during the study period, compared with 9% (58/659) of Thoroughbred racing fatalities reported in a Californian study (Johnson et al 1994) and 12% (15/127) in a British study (Boden et al 2005). The causes of sudden were identified as induced pulmonary hemorrhage exercise 6% and 5% of hypersensitivity reactions in all cases were detected illicit drugs.…”

“…Racing fatalities are an important welfare concern in Thoroughbred horses and they cause major economic losses to the equine racing industry (Boden et al 2005). These fatalities include sudden deaths that occur while racing or training and horses that are euthanized due to catastrophic injuries (Boden et al 2005, Lyle et al 2011.…”

“…These fatalities include sudden deaths that occur while racing or training and horses that are euthanized due to catastrophic injuries (Boden et al 2005, Lyle et al 2011. Reported causes of death in Thoroughbred horses associated with racing or training include catastrophic musculoskeletal injury (CMI), acute abdominal crisis (colic), other major causes of death included respiratory, digestive and multi-organ system disorders (Johnson et al 1994).…”

“…In French the overall mortality rate was 2.47%, and was due, in decreasing order, to foaling (24%), colic (21%), cardiovascular (9%), neurological (8%), respiratory (5%) or infectious (4%) disease (Leblond et al 2000). Post mortem examinations were performed on 43% of horses (77/180), with 97% (61/63) of all metropolitan fatalities and 14% (16/117) of all country fatalities being submitted (Boden et al 2005), sudden death accounted for 26% of all fatalities (46/180) of all fatalities on Victorian racetracks recorded during the study period (Boden et al 2005).…”

The aim of this study was to describe the causes of death in Thoroughbred horses at the Racetrack “La Rinconada”, in Caracas (Venezuela) during 2008-2012. This study was conducted in a cohort of all Thoroughbred horses that died or were subjected to euthanasia. Data was collected retrospectively. Only horses for which a full necropsy report was available were included in the study. The carcass and all internal organs of each horse were examined and representative samples of tissues with abnormalities were collected in 10% neutral buffered formalin and processed for histopathological examination. Samples were collected for bacteriological or virological examination when indicated in gross examination. A descriptive statistical analysis was performed. A total of 532 Thoroughbred horses were examined post-mortem. Of these horses, 44% were females and 56% males. In general musculoskeletal injuries and dilaceration occurred specifically at higher frequency. The total year and horses dead for descriptive statistical analysis was to mean 106.4 and median 125; Standard Deviation: 47.82573; variation (Standard Deviation): 2287.3, population (Standard Deviation): 42.77663 and variance (Standard Deviation): 18229.84. In conclusion we identify and describe the causes of death in Thoroughbred Race Horses in Caracas, Venezuela. In order of importance the causes of death were principally skeletal muscle injuries resulting in fractures euthanasia, abdominal crisis were mostly bowel twists and gastric rupture andrespiratory pathologies such as the pneumonia, pleuritis presented a significant number of cases of pulmonary hemorrhage induced by exercise. Finally the multisystem pathologies were presented in low cases.
