Treatment and study plan

LMA Igel

Device

adults allocated to the LMA Igel group, an LMA Igel device will be inserted intraoperatively

LMA Protector

Device

adults allocated to the LMA Protector group, an LMA Protector device will be inserted intraoperatively

Primary outcomes

  1. The time required for successful placement of the device

    Time frame: Measured from the moment the clinician picks up the LMA device after induction of general anesthesia until the appearance of the first capnography waveform on the monitor with a maximum duration of 60 seconds per attempt and up to three attempts allowed

Secondary outcomes

  1. Documentation of adverse events during placement

    Time frame: During the placement attempt
