Effect of the Aspiration Care Bundle on Preventing VAP

Ventilator-associated pneumonia (VAP) is defined as pneumonia that develops 48 hours after intubation in patients who did not have pneumonia at the time of intubation and who were placed on mechanical ventilation. VAP is known to be one of the most common healthcare-associated infections in patients admitted to intensive care units. VAP is a common nosocomial infection in intensive care units, and its consequences include high mortality, prolonged intensive care unit stay, and increased healthcare costs. There are two types of VAP: "early-onset" and "late-onset." Early-onset VAP develops 48-96 hours after intubation and is caused by microorganisms that are sensitive to antibiotic treatment. The microorganisms responsible for early-onset VAP include Methicillin-Sensitive Staphylococcus Aureus (MSSA), Streptococcus Pneumoniae, Haemophilus Influenzae, and Moraxella Catarrhalis. Late-onset VAP develops 96 hours after intubation and is caused by multidrug-resistant microorganisms. Microorganisms seen in late-onset VAP include Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella species, and Acinetobacter baumannii. Clinical findings observed in patients with VAP include fever (body temperature above 38 degrees Celsius), leukocytosis (white blood cell count above 10,000 mm3), purulent secretion or increased secretion, and new or progressive infiltration on chest X-ray. Many pharmacological and non-pharmacological interventions are used to prevent VAP. Nurses are directly responsible for implementing non-pharmacological interventions and therefore have an important role in preventing VAP. The most important non-pharmacological nursing interventions to prevent VAP are hand hygiene and oral care. In addition, the head of the bed should be elevated to 30°-45°, head pressure should be monitored, and subglottic aspiration should be performed. Various care packages have been developed to prevent VAP. It has been determined that these care packages reduce the incidence of VAP. The aim of this study was to investigate the effect of the aspiration care package applied in the intensive care unit on preventing the development of ventilator-associated pneumonia, and it was planned as a quasi-experimental study.
