I read the article "Total Intravenous Anesthesia (TIA) in a Patient with Werdnig-Hoffman Disease. Case Report", of Resende et al.1, published in this journal with great interest. First, I would like to congratulate the authors for their initiative. However, two points called my attention. The first one refers to the definition of infant, which comprehends the period from 1 to 12 months of age. From 12 months on, it defines preschooler or just child. In the article, the author states the age of the patient as 1 year old, but he does not specify months or days. Probably, this patient has more than 12 months of age and, therefore, calling him an infant is inappropriate. The second and most important point refers to the technique used and to the title of the article. In the title, the expression "total intravenous anesthesia" was used, but in the report it was stated that besides propofol and remifentanil anesthesia was maintained with oxygen and N2O. If a gas with anesthetic properties (N2O) was used, it would not be correct to call this technique total intravenous anesthesia. Besides, he mentioned the article of Crawford et al. 2, who defined the doses of remifentanil for intubation in children. This study was undertaken using 100% oxygen, since the authors probably understand that the addition of gases with anesthetic properties would interfere with the results obtained
