Brief summary

To compare air Q versus ILMA intubation in obese adult paralyzed patient

Detailed description

Evaluate the process of endo-tracheal intubation through Air Q compared to through ILMA regarding number and duration of attempts, laryngeal view grade, time to removal of device over tube without dislodgement and any complication

Interventions

DEVICEAir-Q. ILA insertion of proper size

Success of fiberoptic guided intubation throuhgh Air Q supraglottic airway device

DEVICEILMA insertion of proper size

Success of fiberoptic guided intubation throuhgh ILMA supraglottic airway device

Inclusion criteria

All morbidly obese patient defined as BMI \>40 kg/m2 scheduled for an elective surgery requiring general anesthesia with tracheal intubation were enrolled on the day of their surgery. ASA physical status (I-II)

Exclusion criteria

physical status of IV or V or had a history of impossible tracheal intubation or awake fibreoptic intubation or if preoperative evaluation showed limited mouth aperture \<3.5 cm or showed evidence that an awake fiberoptic intubation or rapid sequence induction would be required patients at increased risk for aspiration of gastric contents, coagulopathy or those with unstable cervical spines or requiring nasal route for tracheal intubation \-

Design outcomes

Primary

Measure	Time frame	Description
success rate of tracheal intubation through each device.	Within a maximum of 5 minutes to confirm success of tracheal intubation through each supraglottic airway devices	success rate of tracheal intubation through each device is defined as end tidal carbon dioxide confirmed placement of TT within a maximum of 5 min tracheal intubation time

Secondary

Measure	Time frame	Description
Insertion time of supraglottic airway devices	It is about 13-19 second for insertion of supraglottic airway devices	Time necessary for insertion was measured from the time the face mask was taken away until the appearance of Co2 on the capnograph while supraglottic airway device in place
