Brief summary
The Laryngeal Tube Suction Disposable( LTS-D) has recently undergone considerable structural changes in design. As these changes may influence the performance of the LTS-D relative to the old LTS-D version the investigator decided to check the new LTS-D in the pediatric version The investigator hypothesized that the LTS-D perform clinically well during general anesthesia with controlled ventilation.
Detailed description
The LTS-D, is a second generation supraglottic airway device, made from the medical polyvinyl chloride introduce in 2005. It is used for maintaining the airway during spontaneous and controlled ventilation during general anesthesia . It has been advocated for prehospital emergency airway management and serves as a useful tool during failed intubations The LTS-D has recently undergone considerable changes in design based on clinical studies and investigators feedback. The new LTS-D is available to adult and pediatric sizes.For childrens the devices is presented in the size 3 for patients of \< 155 cm (\> 30 Kg.), the size 2.5 for patients 125-150cm. (20-30 Kg.), the size 2 for patients of 12-25 Kg, the size 1 for patients of 5-12 Kg and the size 0 for patients \< 5 Kg. As these changes may influence the performance of the LTS-D relative to the old LTS-D version the investigator decided to check the new LTS-D in the pediatric version. The investigator hypothesized that the LTS-D perform clinically well during general anesthesia with controlled ventilation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Seal pressure in cm H2O | one minute | We will measure the seal leak pressure at 60 cm H2O intracuff pressure and the minimal pressure of the cuff to performed effective volume controlled ventilation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time of insertion in seconds | one minute | Was measured as the time after the anesthesiologist removed the facemask until the square-wave capnograph tracing was observed after insertion of the LTS-D. Two attempts at insertion were permitted. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Easy of insertion using a five-point Likert Scale | One minute | Investigators were asked to complete a questionnaire independently and anonymously to record the 'ease-of-use' of the LTS-D. Insertion of the devices was classified as 1= easy, 2= moderate, 3= difficult and 4=impossible. |
