|
Purpose: This study aimed to find out the effectiveness of gum elastic bougies for intubation in comparison to stylet according to airway type using a manikin.
Methods: The study subjects were 52 paramedic students who intubated using a Macintosh laryngoscope and compared stylet and gum elastic bougie use in a 7.5 mmID endotracheal tube, on a manikin with either normal or difficult airway. Difficult airway was made Philadelphia neck collar. Collected data included intubation time, accuracy and ease of intubation, later analyzed by frequency analysis, descriptive analysis, independent t-test, chi square test, paired t-test, and McNemar test using SPSS Statistics 18.0.
Results: There was a significant difference in intubation time according to intubation device and airway type (p=.000). There was no significant difference in accuracy of intubation according to intubation device or airway type (normal airway p=1.000, difficult airway p=.052). There was a significant difference in ease of intubation scale according to intubation device and airway type (p=.000, p=.000).
Conclusion: Based on the speed and ease of intubation, gum elastic bougie is recommended for intubation in patients with difficult airways such as those with cervical injury.
