Identifying Research Methodologies
The authors are R. K. Elswick Jr., M. J. Grap, C. L. Munro, V. A. Hamilton, C. N. Sessler, and K. R. Ward (2011). Chlorhexidine can reduce ventilator-associated pneumonia in trauma patients after a single early administration, according to the Journal of Acute and Critical Care, Heart & Lung, 40(5), e115-e122.
Reasons for Choosing the Article
The article by Grap et al. (2011) was chosen because it tackles the issue—precisely, the relationship between ventilator-acquired pneumonia and the effects of chlorhexidine oral microbial flora.
Goals for the Study
The purpose of the study was to compare the effects of early chlorhexidine treatment (within 12 hours of intubation) vs. a control (no swab) on oral microbial flora and ventilator-acquired pneumonia.
Research Techniques
Grap et al. (2011) gathered data using a quantitative research approach. 135 trauma patients made up the sample for the researchers’ experimental investigation. For the trial, participants were randomly split into treatment and control groups.
Research Methodology’s Strength
High grades were received for the study’s dependability and validity of the experimental research design. The methodology’s success is due in part to the blinding used throughout the assignment procedure and the random assignment of participants to the treatment and control groups.
Richards (2013). (2013). Chlorhexidine-based oral hygiene practices for patients undergoing mechanical ventilation lower the risk of ventilator-associated pneumonia. Dentistry Based on Evidence, 91-2, 14 (3).
Reasons for Choosing the Article
The paper was picked for the evidence-based inquiry because it concentrated on how chlorhexidine works to prevent pneumonia received through a ventilator.
Goals for the Study
The trial aimed to determine whether mechanically ventilated patients’ risk of ventilator-acquired pneumonia could be decreased by using oral hygiene regimens based on chlorhexidine.
Research Techniques
RCTs were utilized by Richards (2013) to assess the effectiveness of oral hygiene regimens based on chlorhexidine. People who were employing mechanical ventilation participated in the testing.
Research Methodology’s Strength
Randomization and randomized controlled trials support the method’s internal and external validity for a specific participant group. The study’s validity was increased by the validity of the questionnaire used to gather and record the data.
