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.

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.
