Abstract:
Electrical burn injuries are one of the most severe forms of trauma. This study aims to investigate the infection complications in electrical burn patients in a referral hospital in Mexico City. A longitudinal retrospective study was conducted, involving electrical burn patients admitted from April 2011 to December 2016. Demographic and clinical data including type of electric burns, infection complications, and mortality was sought. Data were collected at admission and daily until discharge. Number and type of infections and microorganism isolations were sought. Risk factors for death were analyzed. A total of 111 patients were included, of which 96.4% were males, mean age of 31.6±16.22, most injuries were high voltage associated. The total body surface area average was 27.8% ± 19.63. The overall infection rate was 72.9 cases per 100 patients. Mortality was observed in 4 (3.6%) patients. About 59.1% (443/749) had growth for Gram-negative bacteria. Multidrug-resistant Pseudomonas aeruginosa was the most frequent microorganism isolated. Fungi were present in 4.9% of cases. Electrical burn injuries occurred in young males in our study. Infection was frequent, most of them caused by Gram-negative rods with an important rate of antimicrobial resistance; however, an important microbial diversity was present.
