Effects of Intraoperative Gelatin on Blood Viscosity and Oxygenation Balance
Purpose:
We aim to investigate whether hemortheology and oxygenation balance are affected by intraoperative gelatin infusion, whether it poses a threat to the perioperative well-being of the patients, and thus creates difficult conditions for postanesthesia care.
Design:
A randomized controlled clinical trial.
Methods:
After anesthesia induction, 10 ml/kg succinylated gelatin was infused. Arterial blood gas analysis was performed, and whole blood viscosity and vital signs were recoded both before and after the infusion.
Findings:
High shear and medium shear viscosities decreased (P = .003 and P = .04, respectively) after the infusion of both gelatin and Ringer's lactate. The peripheral vascular resistance was not significantly changed by the infusion of either fluid (P = .31). Ringer's lactate reduces the body's oxygen delivery index (P = .01).
Conclusions:
Gelatin better maintains blood viscosity and stabilizes the body's oxygenation balance.

Viscosity is a measure of a fluid's resistance to flow, and it is a useful parameter in the design of efficient product processing and quality control in a wide range of industries. A variety of viscometers are used to obtain the most accurate readings of experimental materials. The standard method of measuring viscosity is through a glass tube viscometer, which...

The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
