In this single-blind clinical trial study, 70children who are candidates for lower abdominal elective surgery under general anesthesia presented at Imam Hossein Hospital in Isfahan will be included in the study and will be divided into 2 groups. In the first group, ventilation with facial mask and in the second group, ventilation with nasal mask will be done for three minutes. Then the reduction in SPO2 and the impossibility of ventilation of patients will be evaluated and compared between the two groups.
