CloSed Project
Improving sedation of children in critical care


Welcome to the third Newsletter of CloSed, a 5-year project funded by the European Union, aimed to improve patients’ treatment in the intensive care setting by studying clonidine.

CloSed will develop a new formulation of clonidine specifically designed for children and conduct a clinical trial in patients under the age of 18 with the aim to generate safety and efficacy data on clonidine in children, to support Paediatric Use Marketing Authorisation (PUMA) application and to develop guidelines for sedation of critically ill newborns and children in the Paediatric Intensive Care Unit (PICU). Throughout the project, the health outcome of children will be of utmost priority and all research activities will be conducted in accordance with European ethical requirements for studies involving the paediatric population.



Project Consortium

The project Consortium comprises 10 European partners: one not-for-profit organisation, five clinical centres, one SME, two universities and one patient organisation, all focused on developing appropriate medicines for children.

Launch of the website on Comfort Assessment


One of the main activities of the CloSed study is the training of medical staff in order to provide the knowledge to obtain the outcome measures defined in the Clinical Study Protocol.
The scoring systems which will be used in the CloSed study are: COMFORT behaviour scale (COMFORT-B scale), Numeric Rating Scale (NRS) and Nurse Interpretation of Sedation Score (NISS).
In this respect, Erasmus Universitair Medisch Centrum Rotterdam (EMC) has developed appropriate training packages using modern technologies including online training, videos and training sessions in order to provide a standardised training for the study staff involved in patient recruitment.
In order to provide further help to healthcare professionals to use these instruments to assess pain, sedation, withdrawal syndrome and paediatric delirium, EMC also has recently launched a website (available at the following address: ...
