Laryngeal mask airway versus endotracheal tube: effects on mechanical power in young children
Impact of Laryngeal Mask Airway Versus Endotracheal Intubation on Mechanical Power and Postoperative Respiratory Complications in Pediatric Patients: A Prospective Observational Study
This will test whether a laryngeal mask airway or an endotracheal tube leads to different mechanical power during anesthesia in children aged 2–5 having elective surgery.

What this trial studies
This prospective, observational single-center study at Konya City Hospital compares mechanical power measured during anesthesia in children managed with a laryngeal mask airway (LMA) versus an endotracheal tube (ETT). Airway choice is made by the attending anesthesiologist based on clinical needs rather than random assignment, and a standardized induction and maintenance protocol will be used. Mechanical power will be calculated from routine ventilator parameters recorded immediately after securing the airway and again at the end of surgery before emergence. Postoperative respiratory complications in the PACU, including cough, hypoxemia, laryngospasm, bronchospasm, increased secretions, and breath-holding, will be systematically recorded.
Who should consider this trial
Good fit: Children aged 2–5 years, weighing 10–20 kg and classified ASA I–III, who are scheduled for elective non-abdominal, non-thoracic surgery expected to last under one hour are ideal candidates.
Not a fit: Children with severe chronic lung disease, uncontrolled asthma, pulmonary hypertension, recent major lung surgery, severe cardiac failure, severe obesity, emergency surgery, or those having abdominal/thoracic or prolonged procedures are unlikely to benefit from this comparison.
Why it matters
Potential benefit: If one airway device is linked to lower mechanical power, clinicians could favor that device to reduce ventilator-related lung stress and postoperative respiratory problems in young children.
How similar studies have performed: Mechanical power has been studied in adults and linked to ventilator-related lung injury, but direct comparisons of LMA versus ETT for mechanical power in young pediatric patients are relatively novel.
