Hemalb Infusion is a sterile, non-pyrogenic solution containing 20% w/v human serum albumin, indicated for use as a plasma volume expander in patients requiring volume replacement therapy. Albumin, a natural plasma protein, plays a critical role in maintaining colloid osmotic pressure and fluid balance within the vascular compartment. Hemalb Infusion is utilized in clinical situations such as hypovolemia due to hemorrhage, burns, surgery, or shock, where rapid restoration of circulating blood volume is essential. The 20% concentration provides a hyperoncotic solution, facilitating fluid movement from the interstitial to the intravascular space, thereby improving hemodynamic stability and tissue perfusion. It is also employed in the management of hypoalbuminemia and in certain cases of nephrotic syndrome, liver cirrhosis, and acute respiratory distress syndrome to restore plasma albumin levels. Hemalb Infusion should be administered intravenously under strict aseptic conditions, with dosage and rate tailored to the patient's clinical status and response. Caution is advised in patients with congestive heart failure, renal impairment, or known hypersensitivity to albumin preparations. Monitoring of vital signs and fluid balance is recommended during therapy to avoid potential complications such as volume overload or allergic reactions.
