Is ProSeal™ A Better Choice Than Classic™ Laryngeal Mask Airway For Children? A Randomized Controlled Trial In The Anaesthetized Non-paralyzed Daycare Children NS Hadzarami1, Rohayu Othman2, Lucy Chan3 1 2
University of Malaya, Kuala Lumpur, Malaysia Hospital Kuala Lumpur, Kuala Lumpur, Malaysia
We compared ProSeal™ and Classic™ laryngeal mask airway (LMA) in anaesthetized, spontaneously breathing children in daycare surgery in terms of number of attempts of insertion, airway sealing pressure, grading at fibreoptic visualization and frequency of gastric insufflation. A total of 60 children (age 1-6 years old) were studied in a non-crossover manner. The patients were randomized for airway management with the size 2 ProSeal™ or Classic™ LMA. After induction of general anaesthesia, the ProSeal™ LMA or Classic™ LMA was inserted. The number of attempts of insertion was counted; airway sealing pressure measured and placement was confirmed by fibreoptic visualization. Upon completion of surgery, the laryngeal mask airway was removed and any complication was documented. We found that fibreoptic position grade 4 was higher in ProSeal™ LMA group (P=0.028) but the overall fibreoptic position grade was similar for both Proseal™ and Classic™ LMA. There was no statistical difference between the two groups for the success rates at first attempt of insertion, airway sealing pressure and frequency of gastric insufflation. Gastric tube insertion in ProSeal™ LMA had a 100% success rate. We conclude that the performance of both ProSeal™ and Classic™ LMA was similar in terms of insertion and placement in the anaesthetized daycare children. Although ProSeal™ LMA provided a better anatomical position than Classic™ LMA, it showed no definite advantage over Classic™ LMA in term of general airway management for children in daycare surgery setting.
