The Effect of Chlorhexidine on Ventilatory Patient in ICU
Part 2: Identifying Research Methodologies
Grap, M. J., Munro, C. L., Hamilton, V. A., Elswick Jr, R. K., Sessler, C. N., & Ward, K. R. (2011). Early, single chlorhexidine application reduces ventilator-associated pneumonia in trauma patients. Heart & Lung: The Journal of Acute and Critical Care, 40(5), e115-e122.
Rationale for Article Selection
The article by Grap et al. (2011) was selected because it covers the subject matter, regarding the effect of chlorhexidine oral microbial flora and ventilator-acquired pneumonia.
Aims of the Research
The aim of the study was to test the effect of an early (within 12 hours of intubation) use of chlorhexidine by swab versus control (without swab) on oral microbial flora and ventilator-acquired pneumonia.
Research Methodology
Grap et al. (2011) used a quantitative research method to collect data. The researchers conducted an experimental study using a sample of 145 trauma patients. The study involved random assignment of participants to a treatment and control group.
Strength of Research Methodology
The experimental research method used in the study rates well in terms of validity and reliability. Some of the reasons for the effectiveness of the methodology include the random assignment of participants to the treatment and control groups and blinding during the assigning process.
Richards, D.1. (2013). Oral hygiene regimes for mechanically ventilated patients that use chlorhexidine reduce ventilator-associated pneumonia. Evid Based Dent. 14(3), 91-2.
Rationale for Article Selection
The article was selected for the evidence-based inquiry because it relates directly to the topic of study, the effect of Chlorhexidine in the prevention of ventilator-acquired pneumonia.
Aims of the Research
The study aimed at finding out whether chlorhexidine-based oral hygiene regimes for mechanically ventilated patients are effective in reducing ventilator-acquired pneumonia.
Research Methodology
Richards (2013) used a quantitative research method to conduct randomized controlled trials (RCTs) that evaluated the effect of oral hygiene regimes using chlorhexidine. The tests were conducted on individuals receiving mechanical ventilation.
Strength of Research Methodology
Randomization and use of randomized controlled trials for a particular group of participants support the internal and external validity of the methodology. The reliability of the study emanates from the use of a reliable instrument to collect the data, a questionnaire to collect and record data.

Rationale for Article Selection
The study relates to the use of topical oral chlorhexidine in reducing ventilator-associated pneumonia. Therefore, it is associated with the topic directly, which affirms the reason for its selection and inclusion in the clinical inquiry.
Aims of the Research
The study aimed at finding whether a reduction of the risk of ventilator-associated pneumonia in critically ill patients was possible through the use of mechanical (toothbrushing), topical oral chlorhexidine, and a combination of toothbrushing as well as chlorhexidine.
Research Methodology
The research methodology used in the study was quantitative in the form of a randomized controlled trial conducted among critically ill patients using mechanical ventilation.
Strength of Research Methodology
The strength of the methodology lies in randomization, which prevents bias and the blinding in assigning participants to groups. The reliability of the methodology involves the collection of data using a pretested questionnaire.
Veitz-Keenan, A, & Ferraiolo, D.M. (2017). Oral care with chlorhexidine seems effective for reducing the incidence of ventilator-associated pneumonia. Evid Based Dent. 18(4), 113-114.
Rationale for Article Selection
The article was selected because it contained evidence of the effectiveness of chlorhexidine in reducing the rate of ventilator-associated pneumonia. Therefore, the article related to the clinical inquiry directly and provided essential answers to the best practice in addressing the problem.
Aims of the Research
The study aimed at evaluating the effectiveness of chlorhexidine in reducing ventilator-associated pneumonia incidence.
Research Methodology
The methodology used in the study was a systematic review of what is already done in evaluating the effect of chlorhexidine in reducing the incidence of ventilator-associated pneumonia.
Strength of Research Methodology
The strength of the methodology relates to the exhaustiveness of the review. The researcher used various types of studies conducted using different methods to answer the research question. They searched, appraised, and synthesized various evidence to establish the effectiveness of chlorhexidine.
