Necrotizing soft tissue infections are among the medical emergencies which treating them requires prompt decision making and clinical interventions including surgery and antibiotic therapy. This is a brief review on some important clinical points about such infections.
Body
Necrotizing soft tissue infections show themselves with cellulitis, bullous lesions, leucocytosis in the CBC, inflammation edema, Fever, pain and local anesthesia. Most of these finding are out of proportion. Perifacial air, vessel thrombosis, fat stranding, lymphadenopathy, fluid tracking and muscle edema can be seen in the CT scanning.
Multiple and aggressive surgical debridement and also antibiotic therapy with broad spectrum antibiotics, are two important pillars to treat the necrotizing soft tissue infections. Any delay in the treatment can result in catastrophic events resulting in expiring the patient. Surgery should be done in an aggressive manner and should be done without any delay after diagnosis and empiric antibiotic therapy with clindamycin and any antipseudomonal carbapenem or piperacillin-tazobactam and also in case of the presence of the clinical suspicion for Methicillin-resistant Staphylococcus aureus, an anti-Methicillin-resistant Staphylococcus aureus antibiotic like vancomycin or the others should be initiated without delay.
Necrotizing soft tissue infections are mainly seen in the patients with diabetes specifically ones affected with poly-microbial type. Considering this, the physician should be aware to keep this diagnosis in mind in the diabetic patients who will be presented with infections of the skin without giving acceptable response to antibiotic therapies or showing signs of systemic pathologies. Usually, surgery can make distinction between necrotizing cellulitis and fasciitis and it should be done aggressively and without delay since time is important to rescue the patient.
During surgery, obtaining the tissue gram stain and cultures is important for going further in the treatment process. Fournier’s gangrene which can be seen in the necrotizing soft tissue infections should make antibiotic therapy to be done in a way that covers the Pseudomonas.
Although there is a score named "laboratory Risk Indicator for Necrotizing Fasciitis" or "LRINEC" score which based on that the patients with necrotizing soft tissue infections can be categorized as High, Intermediate and Low risk, but further studies should be done to completely determine its role and efficacy in clinical settings.
Necrotizing soft tissue infections are among the medical emergencies. Having enough knowledge about such infections and treatment strategies for them are of great importance in the medical and surgical emergency settings.
Clearly Auctoresonline and particularly Psychology and Mental Health Care Journal is dedicated to improving health care services for individuals and populations. The editorial boards' ability to efficiently recognize and share the global importance of health literacy with a variety of stakeholders. Auctoresonline publishing platform can be used to facilitate of optimal client-based services and should be added to health care professionals' repertoire of evidence-based health care resources.
