Abstract

Background: The proseal laryngeal mask airway (PLMA) is a new laryngeal mask device with a modified cuff to improve seal and a draining tube to provide a channel for regurgitated fluid and gastric tube placement. Since PLMA insertion doesn’t require laryngoscopy, it causes less pharyngeal wall stimulation, and less incidence of postoperative sore throat in comparison with endotracheal intubation.
Methods: 100 patients of either sex, age group of 18-60 years, ASA I & II, posted for elective surgeries, to whom general anaesthesia was administered were selected. They were randomly divided into two group (n=50 each). For group A, airway was severed with laryngoscopy and intubation with appropriate size endotracheal tube and for group B, appropriate size PLMA was inserted to secure airway. The hemodynamic responses like Heart Rate and Blood pressure, Oxygen saturation of hemoglobin, postoperative sore throat and abdominal girth were recorded at base line, before induction, after induction, 1^st min, 3^rd min, 5^th min, 10^th min after endotracheal intubation or PLMA insertion and after extubation or removal of PLMA. Conclusion: The hemodynamic response produced when PLMA was used as the method of securing airway was less than the laryngoscopy and endotracheal intubation used for the same. SPO₂ was same in both groups and gastric insufflation was minimal in both groups. Incidence of postoperative sore throat, were more with ETT. Thus PLMA provide a better alternative to ETT in paralysed anaesthetized patients.
