The choice of solution depends on the type and condition of the wound. Commonly used solutions include: 1. Normal Saline (0.9% Sodium Chloride): It is isotonic, non-toxic, and does not interfere with the healing process. 2. Sterile Water: Often used for rinsing superficial wounds. 3. Antiseptic Solutions: Such as povidone-iodine or chlorhexidine, may be used in contaminated or infected wounds. However, they should be used cautiously as they can be cytotoxic. 4. Commercial Wound Irrigation Solutions: These are specially formulated to enhance wound cleansing while being gentle on the tissue.
