Study Summary:
This study investigates the effective dose of propofol, when combined with esketamine, for the smooth insertion of a flexible laryngeal mask airway (FLMA) in preschool children during anesthesia induction. The research is significant as it addresses a gap in knowledge regarding the optimal dosage for different pediatric age groups. The study is a prospective, observer-blind, interventional clinical trial involving two age groups: Group A (1-3 years) and Group B (3-6 years).
The key findings are:
- The median effective dose (ED50) of propofol for group A was 2.67 mg.kg-1 and for group B was 2.10 mg.kg-1, indicating a higher dose requirement in younger children.
- The 95% effective dose (ED95) was 3.72 mg.kg-1 for group A and 2.74 mg.kg-1 for group B.
- One patient in Group B experienced laryngospasm, an adverse event.
This research is important as it provides guidance on dosing propofol for pediatric anesthesia, potentially improving clinical outcomes and safety. The study contributes to the current literature by offering specific dosage recommendations based on age, which can be used to optimize anesthetic care in young children.
The study is registered with the Chinese Clinical Trial Registry Center (ChiCTR2100044317).
