Colloid osmotic pressure: Variations in normal pregnancy

Plasma colloid osmotic pressure in healthy infants

BACKGROUND The plasma colloid osmotic pressure (COP) plays a major role in transcapillary fluid balance. There is no information on plasma COP of healthy infants beyond the first post-natal week. The normal COP in healthy adult subjects (25 mmHg) is currently also applied as a reference value for healthy infants. This study was designed to test whether plasma COP values in healthy infants are t...

Unexpected Normal Colloid Osmotic Pressure in Clinical States with Low Serum Albumin

BACKGROUND In clinical states associated with systemic oxidative stress (OS) and inflammation such as chronic kidney disease (CKD), oxidative modifications of serum albumin impair its quantification, resulting in apparent hypoalbuminemia. As the maintenance of oncotic pressure/colloid osmotic pressure (COP) is a major function of albumin, this study examined the impact of albumin oxidation on C...

Interstitial Fluid Colloid Osmotic Pressure in Healthy Children

OBJECTIVE The colloid osmotic pressure (COP) of plasma and interstitial fluid play important roles in transvascular fluid exchange. COP values for monitoring fluid balance in healthy and sick children have not been established. This study set out to determine reference values of COP in healthy children. MATERIALS AND METHODS COP in plasma and interstitial fluid harvested from nylon wicks was ...

KEY FACTS Colloid Osmotic Pressure in Health and Disease *

The use of synthetic colloids has become commonplace in the treatment of critically ill animals. The theoretical benefits of colloid compared with crystalloid fluid therapy for increasing plasma volume include a more rapid and longer-lasting fluid resuscitation with colloids, a lesser fluid volume necessary to achieve the same level of resuscitation, and reduced risk of edema formation. These b...
