The proseal LMA has advantage over normal LMA
Correct Answer: Comparable to endotracheal tube in preventing aspiration
Description: Advantage of proseal LMA over classical LMA is that it is comparable to ETT in preventing aspiration. The PLMA shows several modifications from the cLMA: The drain tube runs through the device from the tip to the proximal end. When the PLMA is correctly positioned, the tip of the device forms a high-pressure seal with the oesophageal inlet and the drain tube runs in continuity with the oesophageal lumen . oesophageal drain tube posterior inflatable cuff reinforced airway tube integral bite block introducer this reduces the risk of aspiration and hence may be suitable in non-supine positions (e.g., lateral, prone), in laparoscopic surgery (e.g., cholecystectomy, gynecological surgery), and in patients who are obese.
