Conditions
Summary
This prospective observational study aims to compare two commonly used airway management methods-Laryngeal Mask Airway (LMA) and Endotracheal Intubation (ETT)-in pediatric patients undergoing elective surgery under general anesthesia. The primary objective is to evaluate the impact of LMA and ETT on intraoperative mechanical power, an emerging indicator of ventilator-induced lung stress. Secondary objectives include assessing postoperative respiratory complications such as cough, hypoxemia, laryngospasm, bronchospasm, increased secretions, and breath-holding episodes. No interventions will be assigned based on a study protocol; airway management will be determined solely by clinical requirements. Routine ventilator parameters will be recorded, and mechanical power will be calculated using a validated simplified formula.

Interventions
Randomization is not applied in this study. Since the research is observational in nature, the allocation of patients to the LMA or ETT groups is not performed randomly; instead, it is determined by the attending anesthesiologist based on the type of surgery, clinical requirements, and the individual characteristics of the patient. Accordingly, the choice of airway management method is not influenced by the investigators; the treatment process proceeds according to routine clinical practice, prioritizing patient safety and established clinical standards. Group 1: LMA Group Description: This cohort consists of pediatric patients in whom a Laryngeal Mask Airway (LMA) is used for airway management during surgery. Group 2: ETT Group Description: This cohort consists of pediatric patients who undergo Endotracheal Intubation (ETT) for airway management during surgery.
