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.

Mechanical power (MP)
Timeframe: Mechanical power will be measured twice during surgery, as follows: MP1: Immediately after airway placement, before the start of surgery. MP2: At the end of surgery, before the initiation of emergence.
