Dr Tryba has posed several questions regarding our article,1 and we will try to address each of them. First, he questioned the completeness of our literature review. We searched peer-reviewed articles and did not think that review articles presented at a sucralfate symposium, which were published in a journal supplement,2 would necessarily be completely objective. He also pointed out that a high percentage of our patients had head injuries and suggested that many patients suffered from aspiration pneumonia.
