MELENDEZ FLOREZ, Héctor Julio; GALE, Rosely  and  ALVAREZ, Javier. Éxito de inserción y ventilación con tubo versus máscara laríngea por anestesiólogos inexpertos: ensayo clínico controlado. Rev. colomb. anestesiol. [online]. 2007, vol.35, n.1, pp.21-27. ISSN 0120-3347.

The laryngeal Mask (ML( and the laryngeal tube (TL) are two of the last innovations created with the purpose of facilitating the boarding and the ventilation of the aerial route Studies demonstrate minor hormonal answer, smaller trauma of the vocal cords and less changes in the respiratory function. This study compares the success of insertion and ventilation, the hemodynamic answer and the morbidity postinserción between the TL and the ML by inexpert personnel. Defining Success of insertion according to the number of attempts of positioning of the devices and success of ventilation, as the capacity to maintain normocapnia and smaller pressures of 30 aerial route of cms of HÒ. randomized 176 patients, ASA I II, in two groups, following a standard anesthetic protocol, under controlled ventilation. The global success of insertion to the first attempt was of 78,82% (IC95% 73-85) to the second of 95,29% (IC 95% 92-98) and to third of 98,24% (IC 95% 96-100), with 98,83% (IC95% 97- 101) for TL and 98,23% (IC95% 94-100) for the ML, without significant differences between both groups (p=0.546). The ventilation success did not present/display significant differences, 98,82% for the TL and of 96,34% for the ML, p=0.3616. The hemodynamic answer was similar in both groups being diminutions of arterial pressure between 0 and 20%, considered like normal. There were no differences in the pressures of the aerial route and in the capnografía. The morbidity was of 9,76% for ML and 9,42% for TL, p=0.922, being the post operating malaise, the most frequents complair.
