Demise of the Milwaukee Protocol for Rabies.

Abstract

Human rabies has a very high fatality rate and there have only been about 34 well-documented survivors, defined as survival at 6 months after onset of clinical rabies. Many have had serious neurological sequelae. After a young patient survived rabies in Milwaukee in 2004, the approach dubbed the "Milwaukee protocol" has been aggressively promoted as an effective therapy. The protocol has included therapeutic (induced) coma, ketamine, ribavirin, and amantadine and details of the protocol have changed over time. Over the past 2 decades, no subsequent detailed reports have documented evidence of efficacy. There have been at least 64 cases with failure of the protocol. Likely critical care, which has been used for more than 50 years, is an important component of an aggressive approach. The time has now come to abandon the failed Milwaukee protocol for the therapy of rabies and consider new approaches based our current knowledge of rabies pathogenesis.
