Postoperative third-space accumulation should be managed by intravenous
|B||Dextrose in water|
THIRD SPACE refers to sequestration of fluid in a non-functional extracellular space that is beyond osmotic equilibrium with the vascular space.
The goals of perioperative intravenous fluid therapy
a. Replace preoperative deficits
b. Provide maintenance fluid therapy
c. Replace ongoing blood loss
d. Replace insensible losses
e. Replace third space losses.
Third space losses
A.1 ml/kg/hr for minor surgical procedures
B. 15-20 ml/kg/hr for major abdominal procedures.
Fluid is shifted within the functional extracellular fluid compartment, from the
intravascular space to the interstitial space.
