The Southwest Neonatal Advice and Retrieval (SoNAR) is based at the University Hospitals Bristol NHS Foundation Trusts Neonatal Intensive Care Unit at St Michael's Hospital in Southwell Street, with a second hub at Derriford Hospital in Plymouth. 

The SoNAR Team provide clinical advice and transport services for Neonatal Units and Special Care Baby Units within the SouthWest Neonatal Network.

The team works closely with the Neonatal Intensive Care Units in the South West to ensure that infants requiring specialist care can be safely and promptly transferred to the appropriate hospital.  ​They also provide transport services to return infants to their local unit once their condition has improved.

​They also work with colleagues in the Wales and West Acute Transport for Children (WATCh) Team to provide care in times of peak demand across the whole SouthWest Neonatal Network.  The dedicated neonatal Ambulance service is provided by Bristol Ambulance EMS.
