Hetastarch Hypovolemia Case Study

665 Words 3 Pages
Hypovolemia is a state in which the blood volume, specifically the volume of the blood plasma, is decreased. This can also lead to an imbalance in the volume contraction, or a decrease in the volume of body fluid, which includes osmolytes. Hypervolemia is often linked with sodium depletion, and is distinctly different from dehydration. Causes include loss of blood, loss of plasma, and loss of osmolytes via diarrhea and vomiting. It is recognized by tachycardia and diminished blood pressure, as well as delayed capillary refill and pallor. In this experiment, I will be analyzing the different kinds of treatments used on a hypovolemic patient, and determining which one is the most successful. Hypothesis: I hypothesize that an IV infusion of HetaStarch will be the most effective in reducing the effects of hypervolemia and increasing the blood volume, while still maintaining hematocrit levels above critical values, as according to current research, colloids are retained in the vascular system for longer than crystalloids. …show more content…
Methods: In this experiment, I will be measuring the blood volume, hematocrit, and plasma total [osm] levels of a patient who is experiencing blood loss under different experimental treatment conditions over the course of 30 minutes. The treatment conditions I will be using are IV infusions of NaCl at a concentration of 1000mmol/L, HetaStarch 6%, epinephrine 50000, norepinephrine 50000, insulin 1000mu/min, and supplemental O2 at
