Owing to longer intravascular half-life, colloid should expand the intravascular space for longer than crystalloid, and the colloid preload is expected to be present within the intravascular space at the time of spinal anaesthesia.
Osmotically active particles (e.g., lactate) in the active muscles draw an influx of fluid from the intravascular space into the interstitial and intramuscular spaces (20,21,25).
Vasogenic edema, the most common type of cerebral edema, is secondary to the movement of albumin, other plasma proteins, and fluid from the intravascular space into the extravascular space.
Hypertonic IV solutions are fluids with solutes greater than 0.9%, such as 3.0% NS, [D.sub.5] NS, and [D.sub.5]LR, which pull fluid from cells into the intravascular space. Hypertonic solutions are useful for patients with elevated intracranial pressure (ICP) and some trauma patients (Patanwala et al., 2010; Phillips et al., 2009).
The increase in plasma oncotic pressure produced by colloid helps draw fluid into the intravascular space and thereby expands the plasma volume and remains in the intravascular space for a long time.
Microscopy will demonstrate large B cells sequestered within the intravascular spaces; these cells inconsistently express several of the typical B-cell antigens, with CD79a, CD20, MUM1/ IRF4, and CD19 being the most commonly expressed.
After fluid loading the septic group showed little capacity to retain fluid in the intravascular space. These patients experienced a much lower increase in ITBVI than the control group (10 vs 145 ml/[m.sup.2]), and they showed a decreased percentage of fluid retained in the ITBV (5.7% compared to 53% in the control group).
An important contributing factor for these complications is hypovolaemia due to the removal of fluid from the intravascular space during the haemodialysis treatment and the inadequate refilling from the extravascular compartment (Nette, et al., 2002).
The rest is found in what is referred to as the extracellular space, which consists of the blood vessels (intravascular space) and the spaces between cells (interstitial space).
Danish investigators have shown that type 1 diabetic patients have increased transcapillary escape rates of LDL cholesterol from the intravascular space into the arterial wall (Atherosclerosis 2003;170:163-8).
