👉 The physician fluid, also known as colloid solution, is a specialized type of intravenous fluid designed to mimic the composition of plasma in the human body. It consists primarily of proteins, including albumin, which helps maintain osmotic balance and supports the transport of various substances like hormones and drugs. Unlike other IV solutions, the physician fluid contains a higher concentration of proteins, making it particularly beneficial for patients with hypoalbuminemia or those requiring fluid resuscitation, as it helps prevent fluid leakage into tissues and supports better hemodynamic stability. This makes it an essential choice for managing conditions such as dehydration, shock, and acute respiratory distress syndrome.
