ABSTRACT
This study compared the laryngeal mask airway ProSeal [PLMA] and the standard laryngeal mask airway [LMA]. Ninety patients were randomly allocated for airway management with the PLMA or LMA. Patients were anesthetized with neuromuscular blocking drugs [controlled ventilation]. The patients were undergoing non-intra-abdominal surgeries [general, urologic, plastic orthopedic and gynecologic operations]. First-time insertion success rates were higher for LMA, 41/45 versus 36/45 for PLMA. Six patients required two attempts and three patients required three attempts in PLMA group in comparison to the two patients required two attempts and one patient required three attempts in LMA group. Oropharyngeal leak pressure was higher for the PLMA group [28 +/- 5 cm H2O] versus [18 +/- 4 cm H2O] for LMA. Gastric insufflations occurred in three patients in LMA group, also three patients developed hypoxia in the same group. Blood staining after removal occurred in three patients in PLMA group
