PR (per rectum)
Per rectum (PR) refers to a method of administering medication or conducting medical examinations through the rectum. The rectum is the final section of the large intestine, and this route can be used when other methods might be less effective or feasible. Administered substances may include medications like suppositories, or fluids for cleansing procedures, such as enemas. The PR route allows for direct absorption into the bloodstream, which can provide quick relief or effect.
Medical professionals might also use PR as a technique to perform certain examinations or diagnostic procedures. For instance, a rectal examination can help detect conditions like hemorrhoids or tumors. This method is beneficial when investigating symptoms related to the lower gastrointestinal tract.
In summary, PR is a vital technique in medicine providing access for treatment and diagnosis. It plays a significant part in patient care when oral or intravenous routes are not practical or desirable.
