Proseal Laryngeal Mask Airway in Gastrointestinal Surgeries

Abstract

Pro Seal laryngeal mask airway (PLMA) is a new development among supraglottic airway management devices. The modified cuff and drain tube in PLMA makes it a better device over classic Laryngeal mask airway (LMA). This retrospective study was done to know the effectiveness of PLMA in gastrointestinal surgeries. Thirty adult patients of ASA I, II or III who underwent gastrointestinal surgery under general anesthesia with PLMA were reviewed. The following parameters were reviewed: hemodynamic response, ventilatory parameters, ease of gastric tube placement and adverse effects. PLMA was inserted in the first attempt in 28 out of 30 patients. The change in heart rate was 4.9%; mean increase in systolic and diastolic blood pressure after insertion of PLMA was 2% and 1.49% respectively. 100% success was achieved in Ryle's tube insertion. These parameters are comparatively low when compared with previous studies. This shows PLMA is a less invasive alternative to traditional endotracheal intubation.
