With the junior doctors strike under way, the UHCW Trust has issued guidance for people on its patch.
It is particularly asking people to think if there is an alternative to A&E.
A spokesman said: “We would like to reassure our patients that although we are expecting industrial action on Tuesday and Wednesday as a result of the dispute between the BMA and Government, we have plans in place which will minimise disruption and ensure services remain safe.
“Our contingency plans include consultants and other senior staff providing urgent and emergency care as required.
“We may need to reschedule some patient appointments, and decisions to reschedule appointments will be made by the patient’s specific doctor.
“Patients will be contacted individually if they are affected. If patients have not been contacted they should turn up for their treatment as usual. We also do not anticipate any disruption to our Labour Ward or Lucina Birth Centre.
“Although A&E will be operating as usual, given the industrial action taking place, we would urge people to think sensibly about whether it is appropriate to attend or not.
“There will be extra pressure in the system and in order for us to be able to treat the sickest patients quickly we would ask that people consider using pharmacists or their GP, or calling NHS 111.”
