The human body tightly regulates the osmolality of its fluids to maintain cellular function, with blood plasma normally maintained within a narrow range of 275–295 mOsm/kg. The osmolality of the peripheral vein is identical to this systemic blood osmolality, a critical factor for safely administering intravenous (IV) fluids. Variations in the osmolality of infused fluids can have significant physiological consequences for the patient.

TPN solutions are, in fact, very hypertonic, with osmolarity values often exceeding 1500 mOsm/L. This high concentration of solutes requires the solution to be administered through a central venous catheter, not a peripheral one, to prevent serious complications like thrombophlebitis.

According to sports nutritionists, consuming a concentrated energy gel without adequate water can lead to dehydration and gastrointestinal distress. This guide explains exactly how much water you should drink with an energy gel, detailing the differences between standard and isotonic formulations to help you optimize your performance and avoid mid-race mishaps.

According to medical consensus, peripheral parenteral nutrition (PPN) solutions should typically have an osmolarity below 900-1000 mOsm/L. Therefore, a patient receiving a total parenteral nutrition solution with an osmolarity of 1500 mOsm/L infused peripherally faces a significantly increased risk of thrombophlebitis, a painful inflammation of the vein with potential clot formation.
