What solution should be used to irrigate a wound?

The use of saline solution for wound irrigation is considered the best practice in wound care. Saline, which is a solution of salt in water, is isotonic and helps to gently cleanse the wound without causing further irritation or damage to the surrounding tissues. It helps to remove debris, bacteria, and exudate from the wound, promoting a conducive environment for healing.

In contrast, other antiseptics such as alcohol, hydrogen peroxide, and iodine can be harsh on the skin and may damage healthy tissue. Alcohol can cause stinging and irritation, and hydrogen peroxide, while a common antiseptic, can disrupt healing by damaging fibroblasts, which are essential for tissue repair. Iodine, although effective for disinfection, can also be irritating and may stain the skin, leading to unnecessary discomfort for the patient. Therefore, saline is the safest and most effective choice for wound irrigation, making it the correct answer.
