Effect of intrabronchial platelet rich plasma on the exercise-induced pulmonary hemorrhage endoscopic score in thoroughbred racehorses using furosemide: a preliminary study

ABSTRACT The high prevalence of exercise-induced pulmonary hemorrhage (EIPH) in athletic horses constitutes to be a challenge the racing industry and source major concern animal welfare. Both experimental clinical evidence indicate that use autologous platelet-rich plasma (PRP) is promising effector repair variety conditions. present study evaluated effect intrabronchial instillation PRP on EIPH endoscopic scores from 37 Thoroughbred racehorses. Inclusion criteria were for animals EIPH-positive in, at least, two consecutive post-exercise exams receive 250mg furosemide IV four hours before racing. Animals randomly assigned into 3 groups: placebo, control, instillation. All racehorses included had pre- post- treatment compared by statistical analysis. bleeding score group receiving was significantly lower than control placebo groups. No adverse effects observed any during or after experiment. It possible conclude effective reducing this bioproduct can considered as coadjuvant controlling horses.
