comparison of laryngeal mask airway [LMA [TM]] and peilaryngeal airway cobra [C PLA [TM]] in mechancally ventilated anaesthetised pediatrics

ABSTRACT

The laryngeal mask airway is [LMA[TM]] is a frequently used efficient airway device, yet it sometime seals poorly thus reducing the efficacy of positive -pressure ventilation. The Cobra perilaryngeal airway [CPLA [TM]] is a new supraglottic device which consists of a tube and inflatable cuff. The present study compared the LMA[TM] and CPLA[TM] in mechanically ventilated anaesthetized pediatrics. This study was carried out in 46 pediatric patients age range between 6 months and 2 years scheduled for elective surgery, they were divided into 2 group 23 patients each, group I CPLA[TM], Group II LMA[TM] both were inserted after fentanyl, propofol and vecuronium, Mean time of insertion, number of attempts of insertion and repositioning, airway sealing pressure, adequacy of the airway and side effects was recorded. There was no statistically significant differences between groups as regard the mean time of insertion, number of attempts of insertion and repositioning and adequacy of the airway [no leak at 15 cm water peak pressure]. There was statistically significant higher airway sealing pressure in the CPLA[TM] group and higher incidence of sore throat when compared to LMA[TM] group. Cobra Perilaryngeal Airway [CPLA[TM]] is as efficient as the Laryngeal Mask Airway[LMA[TM]] but with better air way sealing pressure and higher incidence of sore throat in mechanically ventilated anaesthestised pediatrics
