A2B
Alpha 2 agonists for sedation to produce better outcomes from critical illness: A randomised, parallel-group, allocation concealed, controlled, open, phase 3 pragmatic clinical and cost- effectiveness trial with internal pilot
Many patients in intensive care (ICU) need help to breathe on a breathing machine and need pain killers and sedatives to keep them comfortable and pain free. However, keeping patients too deeply sedated can make their ICU stay longer, can cause ICU confusion (delirium) and afterwards may cause distressing memories. Ideally we want to keep patients less sedated, but it is difficult to get the balance of sedation and comfort right. The purpose of this study is to compare if patients on dexmedetomidine or clonidine come off the ventilator quicker than those just on propofol. We will also see if there was a difference between the groups in the number of people who experienced delirium in ICU, compare how comfortable people were and measure if participants memories of being in ICU differed.
