Gérmenes asociados a cultivos de punta de catéter en pacientes atendidos en la Unidad de Cuidados Intensivos del Hospital de Especialidades Teodoro Maldonado Carbo en el periodo de diciembre 2021 a diciembre 2022.

Abstract

Central venous catheter-associated infections pose a significant challenge in medical care, albeit their frequency has decreased due to stringent controls. These infections, mainly caused by gram-negative bacteria, enterobacteria, and staphylococci, can be particularly hazardous in critical areas, leading to septic complications and increased mortality risk. An observational, retrospective, cross-sectional, and descriptive study was conducted on patients over 18 years old with central venous catheter infection admitted to the Intensive Care Unit at the Hospital de Especialidades Teodoro Maldonado Carbo. Patients with contaminated or colonized samples were excluded. Gender distribution showed no significant differences. Most cases of CVC infection occurred in older adults. The predominance of gram-negative bacteria in CVC tip cultures contrasted with previous studies reporting higher prevalence of gram-positive pathogens. A high rate of multidrug resistance was found. Recommendations include increasing sample size and conducting more detailed comparisons with other studies to obtain robust and precise conclusions. Future research should include a thorough analysis of drug resistance in isolated microorganisms to develop more effective treatment guidelines.
