Abstract
- BACKGROUND
Patients with major burns accompanied with airway edema need more attention for airway management. Although the Pentax-AWS has an advantage in managing endotracheal intubation more easily, its usefulness cannot be assured if it does not maintain hemodynamic stability in burn patients. The aim of this study was to compare cardiovascular responses and general efficacy of the Pentax-AWS and Macintosh laryngoscopes in burn patients.
METHODS
American Society of Anesthesiologists physical status 2 or 3 adult patients with major burn injury were randomly assigned to group P (AWS, n = 50) or group M (Macintosh, n = 50). Fifty-nine patients assigned to the Macintosh group and no patient to AWS group were excluded because of failure to first intubation. Hemodynamic data at baseline, just before and after intubation as well as 3, 5 and 10 minutes after intubation and grade of sore throat were recorded in two groups. Intubation time, success rate of intubation, number of intubation attempts and the percentage of glottic opening (POGO) scores were also observed and analyzed in all patients.
RESULTS
A statistically significant increase in heart rate just after laryngoscopy was seen in group M. The success rate of the first attempt in group P (100%) was greater than with the group M (46%). POGO scores were higher in group P (97 +/- 4%) than in group M (48 +/- 29%)
CONCLUSIONS
The use of Pentax-AWS offers a reduced degree of heart rate elevation compared with the Macintosh laryngoscope and better intubation environments in major burn patients.
