Intravenous infusion is a common treatment method in clinical practice, which is a widely used nursing operation and a frequently used sterile operation by clinical nursing staff. Intravenous infusion can easily cause leakage during the infusion process. If observation and care are not taken seriously, it not only causes unnecessary pain to patients and increases the number of venous punctures by nursing staff, but more importantly, it hinders the smooth implementation of patient treatment and affects their recovery. If the drug leaks into the surrounding tissues of blood vessels, mild cases can cause local swelling and pain, severe cases can cause tissue necrosis, and even functional impairment, increasing patient pain while also affecting treatment and rescue work. In clinical practice, 50% magnesium sulfate solution is commonly used to wet compress the affected area, but the effect is slow and the therapeutic effect is average. Local wet compress drugs are prone to crystallization, making the gauze harder and less likely to adhere to the skin, which affects the absorption of the medication.

In clinical practice, many family members have found that after infusion swelling, they use towels for hot compress without authorization, which can easily lead to vascular dilation, increased permeability, enhanced local tissue metabolism, increased oxygen consumption, reduced tolerance of tissue cells to hypoxia and stimulation, increased exudation, and is not conducive to the resolution of edema and pain relief.

The cooling paste is a hydrophilic polymer gel with good energy conversion function as the carrier, which mainly contains water rich hydrogel and cooling agent. It is applied to the patient’s pain, and uses the mechanism of water vaporization to take away heat to achieve auxiliary antipyretic and pain relief for local cooling. It has the characteristics of cooling comfort, rapid cooling and pain relief, and convenient use. When using a cooling patch for intravenous infusion leakage, the efficacy is maintained for a long time, it is easy to apply and remove, the operation is simple, it is firmly attached, does not affect the appearance, the patient feels soft and comfortable, and no obvious side effects are found, the effect is significant. After clinical practice, it is worth promoting.

How to use the cooling patch: uncover the transparent film on the surface of the patch, and directly stick the gel surface to the swollen part.
