Prospective, Randomized Comparison of Proseal Laryngeal Mask Airway and Endotracheal Tube in Adults Selected for Elective Laparoscopic Abdominal Surgery

Abstract

Both PLMA and SLIPA were easy to insert (100% success) and ventilate with maximum sealing pressure of 30cm H2o (P = 0.4) with no muscle relaxant. No significant difference (P = 0.265) in intubation time between PLMA and ETT were observed in the study. A significant SpO2 change (P = 0.804, 0.561, 0.657, 0.248, 0.561) measured Pre op, Pre intubation, lmt, 3 mt and 5mts after intubation and there were no significant EtCO2 changes (P =0.861, 0.251, 0.44) measured after intubation was observed. Blood staining in 1/25 cases with PLMA and 2/25 cases with ETT with a P value of 0.561was seen.
