Therefore, fungal coverage is unnecessary

unless the patient is immunocompromised, has a severe IAI with Candida grown from intra-abdominal cultures, or has perforation of a gastric ulcer while on acid suppressive medications[102]. Fluconazole is an appropriate initial Temsirolimus purchase choice for Candida albicans peritonitis. However, increasingly, non-albicans Candida spp., with resistance to commonly used anti-fungals are responsible for candidemia[103, 104]. Studies have shown that echinocandins are both safe and effective in the treatment of invasive candidiasis. Therefore, in critically ill patients echinocandins, such as caspofungin or echinofungin, should be considered for primary treatment[102, 104]. Required treatment duration for Candida peritonitis is 2-3 weeks[102]. Duration of Treatment Because resistant organisms have been linked to imprudent use of antibiotics,

PFT�� order it is important to limit the duration of antimicrobial treatment[105]. Previously, studies have suggested limiting treatment duration for IAI by discontinuing antibiotics when fever and leukocytosis have resolved, and the patient is tolerating an oral diet[106]. More recently, it has been suggested that fixed duration treatment has similar efficacy[107]. The Surgical Infection Society (SIS) recommends that duration for complicated abdominal Talazoparib mw infections should be limited to 4-7 days, and may be discontinued sooner in the absence of clinical signs of infection[40]. In addition, once patients are able to tolerate oral intake, antibiotic therapy can be transitioned to oral dosing for the remainder of their treatment without increased risk of failure[108]. Suggested oral regimens for patients in whom resistance is not a concern are listed in Table 4. Of note, lack of resolution of clinical signs of infection after 7 days of antibiotics implies failed source

control, tertiary peritonitis, or new infection. Further diagnostic work up including labs, cultures and imaging to look for new or continued sources of infection is essential, and should be accompanied by further surgical intervention if warranted[2].

Finally, we must consider patients with acute IAI, for which prompt source control is achieved. In cases where adequate source control is accomplished within 12-24 hours, less than 24 hours of antibiotic treatment is necessary (Table 5). Antibiotic choice in these instances should generally be guided by the aforementioned recommendations for low risk infections.
