Procalcitonin: A Powerful Rescuer on Surgical Floors.

Necrotizing fasciitis (NF) is a rare but life-threatening medical and surgical emergency. It is characterized by necrosis of the soft tissue leaving the overlying tissue unaffected, which delays the diagnosis and treatment. Delay in recognition of the severity of necrotizing fasciitis might lead to serious morbidity and mortality. Diagnosis of NF relies on strong clinical judgment, predictable by severe pain, erythema, and a presence of air under the skin, but all of them are not always present. Management of NF is prompt surgical intervention and antimicrobial therapy. The effectiveness depends on the timely diagnosis of NF because it rapidly spreads and may cause irreversible damage. Various investigations for necrotizing fasciitis have been proposed. However, misdiagnosis is not infrequent and more work is needed to identify the different presentations across the spectrum. We consider changing it to discuss the role of procalcitonin in the diagnosis of necrotizing fasciitis.There is scarce literature about its clinical role in necrotizing fasciitis although it has evolved not only as a prognostic marker but also as a way of differentiating between cellulitis and necrotizing fasciitis. It can also predict the future consequences of septic shock.
