Are the new resuscitation guidelines optimal?

Abstract

Purpose of review: The purpose of this review is to evaluate the 2005 guidelines on cardiopulmonary resuscitation.

Recent findings: International guidelines are based ideally on results from robust clinical trials. They are necessarily constrained in how far they can draw conclusions from experimental data, and have to pay regard to perceived safety and educational issues. Informed opinion can be more radical in drawing from compelling recent experimental findings, particularly when supported by unreplicated or indirect clinical evidence. Those already available cover a range of issues relevant to the guidelines; the most important ones are reviewed here.

Summary: The 2005 guidelines represent a major advance on those previously in use, but on the evidence already available they cannot be considered optimal. Deviations based on good evidence should not be discouraged provided they are approved and preferably monitored by authoritative bodies that should see this as a legitimate role in developing the science of resuscitation medicine. Guidelines for the most pressing of medical emergencies should not be set and inflexible over several years whilst the science behind them continues to advance.
