Evaluación del comportamiento de bioaerosoles bacterianos en unidades de cuidados intensivos neonatales (UCIN), de una institución de salud de alta complejidad en la ciudad de Barranquilla/Atlántico

Bacteria can adhere to a physical medium as the particulate material, and in this way they are able to disperse in the atmospheric environment. They are of great concern within the Health Institutions because their high concentration can increase the possibility of acquiring nosocomial infections (IIH). In the present investigation, the behavior of bacterial bioaerosols in the Neonatal Intensive Care Unit (NICU) of a highly complex health institution in the city of Barranquilla Atlántico was evaluated. For this purpose, five (5) monitoring campaigns were carried out during two days, before and after the visit of the parents to the neonates. A monitoring point was established, located in the central axis of the NICU. The bacterial bioaerosols were collected using an Andersen Thermo Scientific six-stage cascade impactor. Identification of isolated microorganisms was performed using BD Phoenix ™ 100 automated equipment. The results showed an average concentration for the day before and after the visit of 14.1 and 15.5 CFU / m3, respectively. The highest concentrations were found in the 1st and 5th stages, which correspond to atmospheric particle size diameters of approximately ≥7 μm and 1.1 - 2.1 μm, respectively. The NICU showed bacterial concentrations ≥100 - ≤ 600 CFU / m3 exceeding the recommended standards acceptable by the World Health Organization. Additionally, six genera were found distributed in 12 bacterial species. Staphylococcus and Bacillus were the dominant genera; as for the species, Staphylococcus epidermidis, Kocuria rosea, Bacillus pumilus, Bacillus cereus and Pseudomona pseudoalcaligene were classified as pathogenic or opportunistic bacteria.
