A major incident was declared at Belfast's Royal Victoria Hospital on Wednesday due to a large backlog of patients at the A&E department.
The hospital said additional staff had to be called in and extra beds opened to relieve pressure on the unit.
At one stage, 42 people were waiting on trolleys and staff described the situation as "horrendous".
The Belfast Trust said the situation was brought under control just before midnight.
