Ababy is born at term with a bilateral cleft lip and palate and a very small mandible. she requires positive-pressure ventilation because she is not breathing. you are unable to achieve a seal with bag and mask. which intervention is indicated?

You tried to intubate the baby twice, however, both times you were unsuccessful. The intervention that is indicated here in this case is insertion of a laryngeal mask. 
A laryngeal mask is inserted into a person's larynx so that they can breathe more easily since the airways are blocked and thus preventing the person from breathing normally. This is the intervention that this baby needs.
