ACTION: Proximal tubule nonabsorbable, produces an osmotic effect, pulls water into the blood vessels and nephrons from the surrounding tissue.
INDICATIONS:Reduces risk of acute renal failure in low flow dehydration hypotension hypovolemic shock, prevent renal failure druing long surgery reduces intracranial pressure before and after neurosurgery reduces intra occular purssure before opthalmic surgery promotes urniary excretion of toxic substances (drug overdose)
SIDE EFFECTS: HA, N/V Pulmonary Edema
Contraindications: CHF, Anuria, Pulmonary edema, severe dehydrations <12yrs old/ Pg.
ACTIONS: reduces after load, reduces preload, decreasesd fluid volume, causes reduced BP, Pulmonary vascular resistance, rediced systemic vascular resistance, Blocks the chloride pump in ascending loop where 30% of sodium is usually reabsorbed Loss of Na, K, Mg, H2O lost
