Aims: The study was conducted to identify predictors of laryngeal mask airway (LMA) placement failure in pediatric patients and to investigate the relationship between LMA placement failure and postoperative airway complications. Methods: This study was designed as a prospective observational trial including 66 ASA I patients aged 2-12 years who were scheduled for elective surgery. The patients were divided into two groups based on the placement of the LMA: group S (successful placement of LMA at first attempt) and group non-S (non-successful placement of LMA at first attempt). The relationship between LMA placement failure with airway leakage, peak airway pressure, peripheral oxygen saturation, and expiratory CO2 measurements was evaluated. Results: Airway leakage and peak airway pressure was significantly higher in group non-S when compared to group S [(median- IQR) (ml); 10 (4) vs. 5 (5); p<0.001] and [(median-IQR) (cm-H2O); 14 (3.5) vs.13 (2); p=0.038], respectively. Patients in group non-S exhibited a higher incidence of postoperative respiratory complications when compared to group S (72.4% vs 27.6%; p<0.001). Conclusion: Airway leak and peak airway pressure can serve as determinants of LMA failure in pediatric patients.
