The patient's vital signs suggest compromised hemodynamics, necessitating immediate intervention. The goal is to determine the best course of action among the treatment options provided, focusing on stabilizing the patient and addressing the necrotic areas effectively. Given the context, surgical debridement of necrotic sites may be the most appropriate choice to remove infected tissue and improve the patient's overall condition."}
