Statistical evaluation of plasma substitutes based on 10 variables
Critical Care Medicine
|October 1, 1982
Summary
Colloid solutions like dextran-40, dextran-70, and albumin are more effective for shock resuscitation than plasma, gelatin, or Ringer's acetate. A statistical analysis of hemodynamic and metabolic variables confirmed their superior efficacy in restoring physiological parameters.
Area of Science:
- Veterinary Medicine
- Physiology
- Pharmacology
Background:
- Shock resuscitation is complex, with no single variable predicting outcomes or treatment efficacy.
- Evaluating plasma substitutes requires a comprehensive assessment of multiple physiological parameters.
Purpose of the Study:
- To statistically evaluate the effectiveness of various plasma substitutes in treating shock.
- To compare the efficacy of dextran-40, dextran-70, albumin, gelatin, plasma, and Ringer's acetate in restoring hemodynamic and metabolic variables.
Main Methods:
- Shock was induced in 60 dogs, followed by fluid resuscitation with different agents.
- Ten hemodynamic and metabolic variables were measured over 4 hours post-infusion.
- A numerical system was used to statistically analyze the impact of seven therapeutic agents.
Main Results:
- Dextran-40, dextran-70, and albumin restored an average of 7 variables to preshock levels.
- Gelatin and plasma restored 4 variables, while Ringer's acetate restored 3 variables.
- The control group (no infusion) showed no improvement, remaining in shock.
Conclusions:
- 3.5% colloid solutions of dextran-40, dextran-70, and albumin are superior to plasma, gelatin, and Ringer's acetate for shock resuscitation.
- These findings highlight the importance of colloid solutions in managing shock.
- A multi-variable statistical approach provides a robust method for evaluating resuscitation therapies.
