The three operating rooms at the largest hospital on the South Shore have re-opened after surgeries were put on hold because of air exchange issues. South Shore Health says elective surgeries resumed today at the regional hospital in Bridgewater. The ``OR`` closed Monday afternoon after maintenance staff found a badly worn part in the ventilation system. The system needs to be working properly in order for infection prevention. A total of 30 patients were impacted by the temporary closure of the operating rooms. Those procedures are in the process of being rescheduled.
