Influencia de la presencia de Staphylococcus aureus resistente a la meticilina en las complicaciones postoperatorias y en el pronóstico de los pacientes con amputación de extremidad inferior

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most frequently isolated bacteria in wound cultures. MRSA has been linked to lengthened wound healing times, an increase in adverse postoperative outcomes, and mortality. This study investigated the incidence of MRSA in lower extremity wounds and examined outcomes associated with MRSA-infected wounds versus non-MRSA-infected wounds. A retrospective study was conducted. Patients with MRSA-infected wounds were compared with those with uninfected wounds in a 1:2 ratio. Demographics, infection, and stay information were collected. Data were analyzed using SPSS 15.0. 51 patients were included (17 with MRSA and 34 without MRSA). Patients with MRSA had increased lengths of stay and a higher incidence of adverse postoperative outcomes compared with non-MRSA patients. An MRSA infection adversely affects a patient's hospital course. Preoperative screening for MRSA and postoperative surveillance should be considered to prevent and eliminate the spread of this virulent bacterium.

The aim of the current study was to evaluate the prevalence of stump infections after major amputations of the lower extremities.Patients rehospitalized in Hospital de Base of the Medicine School in São José do Rio Preto in the period from January 2005 to January 2007 due to stump infection after major amputations of lower extremities were evaluated in a retrospective study. All the patients underwent prophylactic antibiotic therapy at the time of the surgery. The Fisher exact test was utilized for statistical analysis with an alpha error of 5% (p-value < 0.05) being considered acceptable.A total of 231 patients were submitted to major amputations during this period and 17 (7.3%) were rehospitalized due to amputation stump infections of which 5 (29.4%) died within one month. The association between death due to stump infection and other causes of death during rehospitalizations was not significant (Fisher exact test: p < 0.1). However, death during rehospitalizations was significantly higher than in the initial hospitalization.
