CHg

CHG is an acronym that can refer to several terms across different fields. The most widely recognized meaning in healthcare is chlorhexidine gluconate, a broad‑spectrum antiseptic used to reduce microbes on skin and mucous membranes.

Chlorhexidine gluconate (CHG) is a cationic antiseptic with activity against bacteria, fungi, and some viruses. It is commonly formulated as solutions for surgical skin preparation, oral rinses for dental hygiene, and as impregnated dressings or catheters to prevent infection. In healthcare, CHG is used for preoperative skin cleansing, daily antiseptic patient care, and in dental settings for plaque control. Its effectiveness is enhanced when used with alcohol in certain preparations. Safety considerations include skin irritation and rare allergic reactions; CHG can interact with certain soaps, and long‑term use may cause staining of teeth or tongue with prolonged exposure in dental products.

Beyond chlorhexidine gluconate, CHG can stand for other terms in different domains, including organizations, products, or codes. The exact meaning is context dependent, and no single definition applies universally. When encountering the acronym, identifying the relevant field or providing surrounding context typically clarifies which CHG is being referenced.
