![]() glucose sometimes added to bring solute concentrations similar to extracellular fluidĭo you have to use maintenance crystalloids or can you use replacement crystalloids?.potassium concentrations higher than plasma.used to replace ongoing fluid and electrolyte loss from normal metabolism, not to replace perfusion and hydration deficits or ongoing losses from diarrhoea, for example.So what sort of fluid should you use for maintenance? This maintenance rate is in addition to rehydration rates. The flat 3ml/kg/hr underestimates for small patients and overestimates for larger patients. These formulae better estimate the needs of smaller and larger patients. ![]() Ml/day = 80 × bodyweight (kg) 0.75 (cats) Maintenance rates are typically calculated using the following formulae: This week I want to touch on maintenance fluids. Need for blood conservation strategies in critically ill cats.Previously, we discussed the components of a fluid therapy plan and talked about hydration deficits. Significant iatrogenic contribution to anemia, and b.) the clear Cats with central venous catheters had a greater number Number of phlebotomies (x = 3) per day than those 7 cats that did notĭevelop anemia (x = 1). The 20 cats that developed anemia had a significantly greater In cats requiring transfusion, was not associated with survival, but wasĪssociated with length of hospital stay (the more blood drawn, the longer the The estimated volume of blood collected (determined from the requiredĪmount for the particular test being run times the number of tests) was greater Significantly associated with the development of anemia, and higher transfusion Median number of phlebotomies was 3 per day, and the number of phlebotomies was The ICU, and of these most (74%) developed anemia during the ICU stay. ICU for more than 2 days, and asked whether phlebotomy caused or contributed toĪnemia and whether or not phlebotomy increased the need for transfusion. Monitoring could be a contributing factor. Frequent blood collection for diagnostic testing and Cytokinemia, poor iron availability,ĭiminished erythropoietin responsiveness and other factors may limit Hansen, B and Vigani A Vet Clin SmallĪnemia and may require transfusion. It does require a scientific calculator but I believe it makes a difference: Thus one might consider a more conservative approach to 24 hour canine maintenance fluid requirements in sick anorexic dogs on IV fluids. ![]()
