Randomised (allocation concealed), blinded (patients, outcome assessors), controlled trial {with mean follow up of 23 days}*.


Surgical intensive care unit (ICU) at the university hospital in Leuven, Belgium.


1548 patients (mean age 63 y, 71% men) admitted to the ICU who were receiving mechanical ventilation. Patients were excluded if they were participating in other trials, were moribund, or had “do not resuscitate” orders. Follow up was 100%.

Conventional treatment was continuous insulin infusion …
