Preparation and physiological basis of homemade oral rehydration solutions in emergency settings

The drastic temperature increase along the central Venezuelan coast, combined with the collapse of basic services due to the recent seismic event, exponentially elevates the risk of heat stroke in the population. Under these extreme conditions, the prevention of dehydration represents an absolute health priority to safeguard the lives of affected citizens. When the organism experiences a massive loss of fluids and electrolytes through sweat, plasma volume drops drastically, which can trigger syncope and multi-organ failure of cardiovascular origin. Therefore, understanding the cellular mechanisms that regulate hydromineral balance allows for the execution of effective direct aid protocols within communities.

Mechanism of the sodium-potassium pump and the prevention of dehydration

The efficient absorption of water in the gastrointestinal tract depends on a highly specialized physiological process. First, intestinal epithelial cells (enterocytes) utilize the sodium-glucose cotransport protein to move these elements from the intestinal lumen into the intracellular space. Likewise, the sodium-potassium adenosine triphosphatase enzyme, commonly known as the sodium-potassium pump, actively transports three sodium ions out of the cell in exchange for two potassium ions. Consequently, this osmotic gradient generates a hydrodynamic force that passively draws water into the bloodstream, immediately restoring volemia. For this reason, the design of homemade isotonic solutions is fundamental to guarantee the prevention of dehydration in environments where commercial oral rehydration salts are scarce.

Formulation of isotonic fluids for the prevention of dehydration

The preparation of a safe oral rehydration solution requires measurements to avoid altering the osmolarity of blood plasma. Consequently, dissolving one liter of potable or previously boiled water, combined with six level teaspoons of white sugar and half a teaspoon of common salt, is established. Additionally, the intake of potassium and alkaline bases can be complemented naturally with the juice of a medium lemon if this resource is available in the shelter area. In this way, the final mixture provides the necessary concentrations of glucose and sodium chloride that immediately activate intestinal cotransporters. Ultimately, the massive application of this community protocol drastically reduces hospital admissions due to heat syncope or hypovolemic shock.
