'Playing favourites': Is there bias during patient selection by registrars in an Australian paediatric emergency department?
Bias does not appear to exist in the selection of patients in this Australasian PED. Further study should address the impact of unbiased patient selection on emergency department efficiency and trainee education.
Abdominal surgery increases the synthesis of prostanoids, particularly via the COX-2 isoform. This compromises the ability of the duodenum to contract and to secrete HCO and to adjust luminal osmolality possibly via altered mucosal permeability. It is proposed that studies of gastrointestinal functions in animals subjected to abdominal surgery should include animals pre-treated with a COX-2 inhibitor.
