Abstract

BACKGROUND: Central venous pressure (CVP) is used in many species to monitor right-sided intravascular volume status, especially in critical care medicine. HYPOTHESIS: That hypohydration in adult horses is associated with a proportional reduction in CVP. ANIMALS: Ten healthy adult horses from the university teaching herd. METHODS: In this experimental study, horses underwent central venous catheter placement and CVP readings were obtained by water manometry. The horses were then deprived of water and administered furosemide (1 mg/kg IV q6h) for up to 36 hours. Weight, CVP, vital signs, PCV, total protein (TP), and serum lactate were monitored at baseline and every 6 hours until a target of 5..
