The Clinical Efficacy of Laryngeal Mask Airway in Elderly Patients: Comparison With Young Adults

There are some differences between elderly and young adult patients regarding the anatomy of upper airways. Elderly patients have larger upper airways than young adult patients at all pharyngeal levels as revealed by CT. Another study explained that there is a progressive descent of the larynx and epiglottis with aging, which lengthens the upper airway and possibly makes it more likely to collapse.

The aim of this study is to compare the clinical efficacy of laryngeal mask airway (LMA) in elderly patients with young adults. In this study, the investigators will measure the ease of insertion, success rate of insertion, the time of insertion, oropharyngeal leak pressure, gastric leak pressure, fiberoptic position and intraoperative complications of the classic LMA.

  • Patients aged 20-40 and 65-85years
  • ASA status 1-2
  • Undergoing minor urologic surgery or lower extremity surgery
  • Undergoing general anesthesia using classic LMA

Exclusion criteria

Treatment and study plan

classic LMA insertion

Procedure

Primary outcomes

  1. oropharyngeal leak pressure

    Time frame: 24 hours

    After successful placement of LMA, airway leak pressure was determined by adjusting the expiratory valve of the breathing circle to 40 cmH2O(fixed fresh gas flow 3 L/min) and recording the pressure when equilibrium was reached.
