ABSTRACT

Introduction. The infectious processes caused by multiresistant microorganisms have had an increase the last years, which has greater relevance at big complex hospitals due to the great number of patients that are attended in the intensive care units where procedures invasive are held, to longterm antibiotics are used and aggressive germs remain in the surfaces around the critical patient. For this reason, attention and vigilance of these cases, constitute a challenge for intensive care professionals, infectologists and microbiologists. Methods. It was made a descriptive analysis based on observation, of 39 patients to detect multiresistant microorganisms present in the nasal and rectal exudates performed in the intensive care units of Medical Surgical Research Center, at 24 and 72 hours since the entrance to the service. The criteria of inclusion were predisposing factors such as previous entrances, prolonged hospitalization and the use of antibiotics. Results. In 30% of the studied patients presented a colonization by multiresistant microorganisms, predominating the Bacillus gram negative not fermentator and with a level location of Nasopharingeal exudate fundamentally. The patients with prolonged stay present bigger positiveness in their Nasopharingeal exudate, while in the previous entrances to hospital predominated the presence of multiresistant microorganisms in the Rectal exudate. Conclusions. In this work, there was a coincidence between the positive results of the nasal exudates and the results of cultures of respiratory secretions.
