Background: This study was designed to compare the effects of using a laryngeal mask airway (LMA) and endotracheal intubation on airway resistance and compliance in patients undergoing orthopedic surgery under general anesthesia. Evaluating these two methods is crucial for improving respiratory quality and reducing complications related to airway management in patients.
Methods: This analytical cross-sectional study was conducted on 50 patients undergoing orthopedic surgery under general anesthesia at Hospital in Bandar Abbas between May and September 2024. The patients were equally divided into two groups: the first group received a laryngeal mask airway (LMA), while the second group underwent endotracheal intubation under general anesthesia. The primary variables, including airway resistance and compliance, were measured at 0, 15, 30, and 60 minutes after anesthesia induction. Demographic characteristics such as age, gender, and ASA class were also recorded. Data analysis was performed using SPSS version 21, with descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistical tests (Mann-Whitney U test and Chi-square test), considering a significance level of P<0.05.
Results: The findings of the present study showed no statistically significant differences between the two groups regarding age distribution and ASA class. A comparison of airway resistance and compliance between genders revealed no significant differences at 0, 15, 30, and 60 minutes. There was no significant difference between the two anesthesia groups (laryngeal mask airway and endotracheal tube) in terms of age distribution. There was no statistically significant difference in ASA classification between the two anesthesia groups. At minute 0 of anesthesia, airway resistance was significantly higher in the endotracheal intubation group compared to the LMA group (P<0.001). At 30 and 60 minutes of anesthesia, airway resistance remained significantly higher in the endotracheal intubation group (P<0.001). Airway compliance was significantly higher in the LMA group at all measured time points (0, 15, 30, and 60 minutes) compared to the endotracheal intubation group (P<0.001).
Conclusion: The results of this study demonstrated that using a laryngeal mask airway (LMA) compared to endotracheal intubation leads to improved airway compliance and reduced airway resistance during anesthesia. These findings may influence the selection of anesthesia methods and enhance postoperative care quality.
