Two or three interviews?

摘要

To the Editor:-We have read with great interest the manuscript by Davidson et al., related to the incidence of awareness in a pediatric population. We should congratulate the authors for their effort.They report an incidence of awareness of 0.2%. This value is significantly lower than others studies, including a previous one from the same author.2We would like to add some comments to the discussion, and specifically another possible explanation for the lower incidence of awareness.The authors in this study conducted only two postoperative interviews, at 24 and at 72 hours. They claimed that a third interview at 30 days had low positive findings, although in the previous study by the same authors they conducted three interviews and the last had a positive findings of 29%. Two of the seven reported cases appeared with the third interview.2 The overall incidence of awareness in the pediatric population was 0.8%, over 921, significantly higher than the present study.
