Anaesthesia, the prestigious journal of the Association of Anaesthetists of Great Britain and Ireland (AAGBI), has electronically pre-published a study of the UAM independently conducted by researchers at Great Ormond Street Hospital for Children and Homerton Hospital in London and the Royal Hospital for Children in Glasgow. In the words of the researchers, “The Universal Anaesthesia Machine was found to be reliable, safe and consistent across a range of tests during targeted functional testing.” The abstract for the article is posted here.

The research includes an extensive set of tests by biomedical engineers at Great Ormond Street to test the UAM for delivery of oxygen under various conditions; accuracy of the vaporizer; and simulated failure conditions common to hospitals with fragile infrastructure. The UAM was clinically evaluated for pediatric use in a 200 patient study at the Royal Hospital for Children. Patients ranged from 34 weeks to 16 years in age, and 1.6 to 82kg in weight. Patient complications were limited to three cases of post-extubation laryngospasm.

We are particularly proud that the authors point out that these tests far exceed basic industry requirements, and that Gradian deserves credit for supporting an unusual degree of scrutiny for a new anesthesia machine. The study was conducted entirely under the auspices of the authors with no prior review by Gradian. Gradian donated the two UAMs to the hospitals and provided a travel grant for one author to present early findings at an international meeting.
