PROSEAL LARYNGEAL MASK AIRWAY : A STUDY OF 100 CONSECUTIVE CASES OF LAPAROSCOPIC SURGERY

Tracheal intubation and controlled ventilation is the gold standard for the anaesthetic management of a patient undergoing laparoscopic surgery. The ProSeal laryngeal mask airway (PLMA), a modified version of the Classic laryngeal mask airway (LMA), is being considered as an alternative airway device for a wide range of laparoscopic surgical procedures. The aim of the study was to assess the use of the PLMA as a ventilatory device in anaesthetised paralysed patients for various elective laparoscopic procedures. This prospective study comprised 100 patients between the age of 18-85 years, of either sex, belonging to physical status ASA IIII. We assessed haemodynamic responses to insertion of the PLMA, ventilatory parameters, ease of gastric tube placement, gastric insufflation and any postoperative complications. The statistically analysed results showed that the PLMA caused minimum haemodynamic responses to insertion, was a reliable airway management device ensuring adequate ventilation and providing an effective glottic seal in all but one patient. It allowed easy passage of gastric tube. There were three cases of oesophageal regurgitation but no incidence of pulmonary aspiration. Sore throat was reported in three patients.
