Paronychia in Emergency Medicine Follow-up
- Author: Heather Murphy-Lavoie, MD, FAAEM; Chief Editor: Pamela L Dyne, MD more...
Further Inpatient Care
- Admission for paronychia is rarely required unless associated with a significant cellulitis, tendonitis, or deep space infection of the hand requiring IV antibiotics.
Further Outpatient Care
- Warm water soaks are the mainstay of treatment. Early in the course of this disease, prior to the development of an abscess, frequent soaking may be sufficient to resolve the infection.
- Instruct patients to leave any wick in place for 24-48 hours, depending on the depth and extent of the purulent space.
- After removing the wick, patients can begin warm soaks 3-4 times per day and should have a follow-up examination in 48 hours after incision and drainage to assure the infection is resolving appropriately.
Deterrence/Prevention
- Trim hangnails to a semilunar smooth edge with a clean sharp nail plate trimmer. Trim toenails flush with the toe tip. Do not bite the nail plate or lateral nail folds.
- Avoid prolonged hand exposure to moisture. If hand washing must be frequent, use antibacterial soap, thoroughly dry hands with a clean towel, and apply an antibacterial moisturizer.
- Wear rubber or latex-free gloves.
- Control diabetes mellitus.
Complications
- Paronychial infections may spread to the pulp space of the finger, developing a felon.
- If neglected, infection may continue to spread to involve the tendons or deep spaces of the hand.
- Secondary ridging, thickening, and discoloration of the nail may be observed.
- Nail loss may occur.
Prognosis
- The prognosis is usually good if treated promptly.
- The incidence of chronic paronychia is increased among immunocompromised individuals.
