    Abstract:
    The ProSeal laryngeal mask airway (PLMA) offers a more effective seal and is easier for gastric tube placement to prevent aspiration than the classical laryngeal mask airway. However, it is more difficult to insert with the digital and introducer tooling techniques. The Rusch Flexi-Slip stylet (RFSS) is an accessory intubation tool that consists of a malleable coated wire and a soft atraumatic tip. It has been reported that it can facilitate easier insertion of the PLMA. Here, we report two cases in which the PLMA could not be inserted correctly on the initial attempts, and with successful placement of the PLMA after using an RFSS. In the first case, three attempts to insert the PLMA with the digital and introducer tooling techniques were unsuccessful. The second case was known to be difficult for PLMA placement because, in a previous operation, PLMA insertion for general anesthesia was unsuccessful, and in that instance required endotracheal intubation for general anesthesia. In both cases, the PLMA was successfully inserted using the RFSS technique, without difficulty. The RFSS technique offers several advantages for PLMA insertion, including the provision of effective support and a soft tip for the PLMA insertion. Other techniques to facilitate the insertion of the PLMA, including priming the drain tube with a guide are discussed. We recommend that the RFSS technique offers an effective method for cases with difficult insertion of the PLMA.
