Clinical guidelines and drug calculators

For healthcare professionals

Our policy

These clinical guidelines have been produced by South Thames Retrieval Service (STRS) at Evelina London for nurses, doctors and ambulance technicians to refer to in the emergency care of critically ill children.

These guidelines represent the views of STRS which were produced after careful consideration of available evidence in conjunction with clinical expertise and experience. The guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient.
