An interventional study of classic LMA insertion in Minor Urologic Surgery and Lower Extremity Surgery, sponsored by Yonsei University. Completed at 1 site in Korea, Republic of. Open to participants aged 20 Years to 85 Years. Per ClinicalTrials.gov, last updated 2014-02-19.
Sponsored by Yonsei University · Not applicable, Interventional, and Treatment
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.
Yonsei University is the lead sponsor of 1,387 studies on the registry; 232 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
young adult patients undergoing minor urologic surgery or lower extremity surgery
Procedure: classic LMA insertion
elderly patients undergoing minor urologic surgery or lower extremity surgery
Procedure: classic LMA insertion
oropharyngeal leak pressure
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.
Time frame: 24 hours
