When does a cold require intravenous (IV) fluid therapy?

Under normal circumstances, most colds do not require intravenous (IV) infusion. This is because the majority of colds are caused by viral infections, for which there are currently no specific antiviral drugs available, making IV therapy generally unnecessary. Administering antibiotics not only fails to treat the common cold but may also disrupt the body's microbial balance and interfere with the normal renewal of the immune system, thereby weakening the body's natural defense mechanisms. While IV infusions can replenish water and electrolytes through the veins, providing temporary relief, this only masks symptoms superficially.

If a patient has a mild fever due to a cold, non-pharmacological treatments may be considered, such as resting in bed, placing a damp towel on the forehead, wiping major arteries with a cool towel, drinking plenty of fluids, getting adequate rest, and supplementing with vitamins. If the fever persists, increased fluid intake and frequent urination can help accelerate the elimination of the virus from the body. Additionally, it is advisable to drink sugared water or light saline solution—sugared water helps restore energy, while sweating during fever causes loss of salts, which can be replenished by drinking lightly salted water. When body temperature rises to 38.5°C or higher, it is recommended to use antipyretic medications such as ibuprofen to reduce fever.

If a patient's cold and fever last longer than seven days, it is advised to visit a正规 and professional medical facility to check for possible underlying conditions and receive appropriate treatment under the guidance of a qualified physician, thus avoiding potential complications or adverse outcomes.
