Surgical infections

Fever is common in surgical patients. The list of potential causes is long and includes many noninfective etiologies. ⋯ The workup and therapy for the individual patient may differ, depending on the underlying disease and clinical appearance and the clinician's suspicion for infection. Subsequent testing should be based on the clinical findings. Perhaps more money is wasted in the evaluation of early postoperative fever than on any other aspect of postoperative care.

ReviewRecommendations and reports about central venous catheter-related infection.
Central venous catheters (CVCs) are used to deliver a variety of therapies, as well as for measurement of hemodynamic parameters. The major associated complication is catheter-related blood stream infection (CRBSI). ⋯ Central venous catheters are used commonly to deliver a variety of therapies, such as large amounts of fluid or blood products during surgery or in intensive care units, chemotherapy, and parenteral nutrition, as well as for measurement of hemodynamic variables. The major complication associated with CVCs is CRBSI.

Yeasts and molds now rank among the most common pathogens in intensive care units. Whereas the incidence of Candida infections peaked in the late 1970s, aspergillosis is still increasing. ⋯ The incidence of invasive fungal infection is increasing, but so too are the choices of agents for therapy. For reasons of efficacy and safety, therapy with an echinocandin or azole antifungal agent is supplanting the use of polyenes.

A substantial proportion of patients become colonized with Candida spp. after surgery, but only a minority subsequently develop invasive candidiasis. However, clinical signs of severe infection manifest only late, presenting a challenge for diagnosis. Better knowledge of the pathogenesis of candidiasis and new compounds have improved the prognosis but also encouraged the emergence of non-albicans strains of Candida. ⋯ After surgery, empiric treatment must be restricted to patients in whom the dynamics of Candida colonization predict a very high risk of invasive candidiasis. Prophylaxis should be limited to the small group of patients in whom its efficacy is proven.

Patients with cancer suffer alterations of their metabolic state and nutritional depletion. This review was designed to evaluate the effect of different nutritional regimens on surgical outcomes. ⋯ Enteral immunonutrition should represent the first choice to nourish surgical subjects.
