Material and method: A hundred consecutive subjects, aged one to four years, without neurological deficits and with complaints of nasal obstruction were examined by transnasal flexible endoscopy (TFE). Study design: Prospective clinical randomized. Aim: The proposal of the present study was to evaluate the efficacy of choral hydrate as a sedative for the conduction of the exams, in the dose of 100 mg/kg PO. We assessed facility of the procedure as a result of the sedation and possible complications. All the 100 patients were sufficiently sedated with the administration of chloral hydrate in the described dose. Conclusion: It allowed conduction of TFE with no need for movement restriction by parents, association of another more powerful drug nor general anesthesia. There were no complications.
