![]() Isotonic fluids distribute within the EC according to volume (75% interstitium, 25% plasma). Polysaccharide based: hetastarch, pentastarch, dextran.Protein based: plasma, whole blood, hemoglobin products, albumin.Hypotonic : (Plasmalyte 56, Normosol M, 0.45% Saline, 2.5% Dextrose)Įditor's Comment - Use these for maintenance fluids.Hypertonic : (5% bicarbonate, 7.2% saline, 0.9 % sodium chloride with 5% dextrose).( Editor's Comment - Use this for replacement of deficits and NOT maintenance. ![]() Isotonic: Lactated Ringer's, Normosol R, Plasmalyte 148, 0.9% sodium chloride, isotonic bicarbonate).It is absolutely essential that the initial body weight be measured and subsequently recorded at regular time intervals. Dehydrated, hypoglycemic, recumbent foals with obvious gastrointestinal disease, or major fluid deficits due to diarrhea, evaporative losses. Weak or ill foals with weak to no suck reflex.Normal urine output is high, (5-10 ml/kg/h), and specific gravity is low (320 days. Milk intake may approach 150-250 ml/kg/day in slightly older foals!! This large fluid intake is necessary to provide adequate energy from the all milk diet and to maintain appropriate digestive processes. Fluid intake as milk in the newborn nursing foal approaches 80 to 100 ml/kg/day (4 to 5 L/day in a 50 kg-foal) taken as small frequent feedings which may range from 100 to 300 ml every hour or two.These factors contribute to larger insensible fluid losses and a greater tendency to lose body heat in cool or drafty environments. Foals have a higher surface area to body weight ratio and a higher resting respiratory rate. ![]()
