Ventilator-Associated Pneumoni A Literature Review

It has been repeatedly stated that oral care is important in the prevention of ventilator-associated pneumonia (VAP). Endotracheal intubation predisposes patients to developing VAP. The tube acts as a conduit from the mouth to the lungs – a perfect track for bacteria to descend upon. Khezeri, et al. (2014) suggest that “the presence of an endotracheal tube (ETT) inhibits normal coughing, normal swallowing, and the protection of the trachea contact by epiglottis closure.” In addition, an endotracheal tube keeps the patients mouth open – leading to dryness. Bacteria are not washed away by saliva. Also, Landgraf, et al. (2017) mention that the presence of an endotracheal tube in the mouth causes “changes in the oral epithelium” which “might indicate risk for infection in intensive care patients

As a nurse in a skilled nursing facility, oral hygiene care is very important, but the importance significantly increases when our patients are functionally dependent or cognitively impaired. These patients are unable to perform this task and depend on nurses to provide daily care. Nurses need to pay close attention for potential problems. They will need to perform assessments, develop oral care plans, and identify preventions and strategies to eliminate any potential problems. Poor oral health has been linked to serious systemic illnesses including diabetes mellitus, stroke, hypertension, myocardial infarction and aspiration pneumonia (Dyck et al., 2012). Patients who suffer from a lack of oral care can have a dramatic impact to their

In clinical experience, it is seen that many patients in the Intensive Care Unit (ICU) are on mechanical ventilation. These patients range from having head trauma, heart surgery and respiratory problems yet there is no clear, concise systematic standard oral care procedures noted on the different floors in the hospital. Oral care is a basic nursing care activity that can provide relief, comfort and prevention of microbial growth yet is given low priority when compared to other critical practices in critically ill patients. The Center for Disease Control reveals that Ventilator-Associated Pneumonia (VAP) is the second most common nosocomial infection that affects approximately 27% of critically ill patients (Koeman, Van der Ven & Hak,

The purpose of this document is a critical study and analysis of the oral care provided by nursing staff as part of the Ventilator Care Bundle (VCB) and to assess whether the frequency of mouth care performed is related to the prevention of Ventilator Associated Pneumonia (VAP) in patients mechanically ventilated (Zilberberg et al. 2009).

To encourage physicians, ICU nurses, and respiratory therapist to use the ventilator associated pneumonia bundle in all ventilated patients in an intensive care unit.

Even though the consequence of saline instillation on a ventilator patient in the acute care setting is pneumonia or the patient may become hemodynamically unstable, this practice remain contentious, the practice of this procedure will also decrease the oxygenation. (Ayhan, et al., 2015),

Endotracheal tubes containing a tapered cuff have recently been approved by the United States Food and Drug Administration and, based on the findings from in vitro and in vivo studies, are believed to achieve a better tracheal seal (Bowton et al., 2013). This enhanced fit is suggested to reduce the passage of potentially contaminated secretions around the cuff and into the distal airway of mechanically ventilated patients, thereby decreasing the development of VAP. In a study executed by Bowton et al. (2013), researchers examined whether these tapered endotracheal tubes would be more effective in reducing actual rates of VAP. Their study utilized a two-period observational approach in which each study period took place over six of the same calendar months so as to eliminate potential variations in season related to VAP. All adults over the age of 18 who were admitted into a variety of specialized ICUs, whose VAP rates closely resembled the average of all ICUs in the United States, were included in the study. During the first six month period, all endotracheal tubes utilized by the facility contained the standard, barrel-shaped cuff. Following this period, an audit was performed to ensure that all of these tubes were removed and, subsequently, they were replaced with tapered-cuff endotracheal tubes. Additionally, all emergency medical

Nosocomial infections relate directly to nursing care so nurses should understand the pathophysiology, risk factors, and prevention strategies for VAP.

Ventilator-associated pneumonia is a bacterial infection that occurs in the lower respiratory system within the first 48 hours of endotrachal intubation (Lewis, Dirksen, Heitkemper, Bucher, & Camera, 2011). Although any hospital patient is susceptible to pneumonia, ventilator dependent patients are at the highest risk of acquiring pneumonia. The purpose of this paper is to identify the risk factors, incidences, and preventions of ventilator-associated pneumonia (VAP) using a quantitative research study performed in Malaysia. “The aim of this

Ventilator associated pneumonia (VAP) is a hospital acquired infection occurs in the intensive care unit (ICU) for the patients who are on mechanical ventilator. It further complicates the hospital course by extending the length of stay, increase the cost of treatment, and increases the mortality rate. It is estimated that about 1% to 3% patients on mechanical ventilator develops VAP per day. Compared to the previous years, the Chlorhexidine mouth care and other ventilator bundle strategies decreased the VAP rate. Evidence based research studies proved that almost 89.7% reduction in VAP occurs after the implementation of ventilator bundle and other care related to it (Hutchins et al,

The Ganz et al. (2009) research was performed in order to evaluate the ICU nurses oral care routines and if they were using appropriate, up-to-date evidenced based techniques and lastly if evidence-based practices (EBP) was associated with personal demographics and professional characteristics. Ganz et al. (2009) had found that previous research and studies has shown that poor oral hygiene may contribute to greater risks for pneumonia which results in an increase in mortality and morbidity (Ganz et al., p 133). In fact some of the research studies had stated that there was no documentation of the nurses oral care practices and these practices were not even up-to-date with recent evidence (Ganz et al., p 133). In addition to that, ventilator-associated

The study subjects were gathered from various ICU centers at various institutions, which is appropriate for study given the study objective and what the study was aiming to examine and determine (using a study drug vs. placebo in an ICU environment). Inclusion criteria were appropriate to assess the effects of the anti-pyretic acetaminophen due to their specificity of including those patients who were febrile with an infection that had been initiated with antimicrobial therapy. The exclusion criteria was extensive and included patient characteristics and disease states that may have skewed the true effect of acetaminophen. It was appropriate to limit these patients with the exclusion criteria from receiving treatment since their comorbidities

In addition to following policies and procedures, nurses are constantly looking to improve best practices and reduce the amount of people affected by a certain illness or infection. Chlorhexidine bathing can be seen in critical care settings, surgical floors, and other medical floors. However, it’s not a practice that is implemented in all health care settings or hospitals.
