False statement about colloids is:
|A||Expands plasma for 2-4 hours|
|C||Expensive as compared to crystalloids|
|D||Replaced in 1:1 ratio for blood loss|
|E||None of the above|
Crystalloids may be hypotonic, isotonic or hypertonic but colloids are always hypertonic and it is how they work i.e., due to hypertonicity they are retained in vascular compartment and indraws water from interstitial tissue maintaining the plasma volume.
Colloids effectively expand plasma for 2-4 hours while crystalloids for 20-30 minutes only.
