Comparison study of success of Laryngeal Mask Airway insertion between Inflated cuff and Deflated cuff techniques in non paralyzed anesthetized Patients Chaiyaphum Hospital

Abstract

A Quasi-experimental research study compared result of the success of laryngeal mask airway insertion between inflated cuff and and deflated cuff techniques in non paralyzed anesthetized patients Chaiyaphum hospital.  60 non paralyzed anesthetized patients from 15 December 2015-30 April 2016 were random. The research instruments were 1).laryngeal mask airway 2). The devices were regard to number and duration of insert attempt, sore throat and airway trauma were assessed by content validity devices. Data analyzed using descriptive statistic (l.c., percent, mean and standard deviation) and inferential statistic was independent t-test, chi square, Fisher’s extract test.

The result found that: Data of group 1 was similar to group 2,the  success of insertion in male 96.3% , age 66-71 years 36.7 %, average weight 59-60 kg, average height 166-168 cm, ASA class 2 66.7% malampati class 1 76.6%. result of success insert laryngeal mask airway between inflated cuff and deflated cuff techniques no statistical significance.

Conclusion: Inflated cuff and deflated cuff laryngeal mask airway insertion are acceptable.

According to the success, a further study relating to other factors that affect the success of laryngeal mask airway insertion technique should be conducted to understand root causes and be able to find more inclusive solutions. The examples of cases that should be studied include cleft lip, cleft palate patients with overlapped teeth issue as their oral cavities are narrowed and not suitable for laryngeal mask airway insertion which will cause various complications.
