The Effect of Ultrasonographic Airway Measurements and Anatomical Differences on Laryngeal Mask Placement in Young and Older Adults: A Prospective Observational Study
Conditions: Airway Management, Laryngeal Mask Airway Insertion Skill
Sex: All
Ages: 18 Years – N/A
Healthy volunteers: No
Enrollment: 188
Sponsor: Duzce University
Location: Duzce University Düzce Düzce
Summary
This prospective observational study aims to compare ultrasonographic upper-airway measurements and age-related anatomical differences between young adults (18-40 years) and older adults (\>65 years), and to evaluate their effects on laryngeal mask airway (LMA) placement success and position accuracy. Preoperative airway ultrasonography measurements will be assessed, followed by evaluation of LMA placement, ventilation efficacy, insertion attempts, placement time, and complications. Ultrasonography will also be used to assess LMA position after placement, with confirmation by leak testing and fiberoptic evaluation. Preoperative and postoperative gastric volume will additionally be assessed.
Eligibility Criteria
Inclusion Criteria:
* Patient or legally appropriate representative/relative accepts participation as applicable.
* Surgery suitable for LMA placement.
* Age 18-40 years or \>65 years.
Exclusion Criteria:
* Pregnancy
* Age \
