The group which runs Portiuncula Hospital is operating a helpline for all users of its maternity services who may have concerns after a review identified "apparent deficiencies" in the care of seven babies.
The helpline, which is running this weekend, was set up after it emerged that two babies died and five others were deprived of oxygen during birth at the Ballinasloe hospital last year.
The Saolta Hospital Group, which includes Portiuncula is urging any maternity service users with concerns to contact the helpline on 0909 624 620 between 9am and 5pm today, tomorrow and Monday.
Support services will be made available to affected families.
The apparent deficiencies relate to the interpretation of tracing of the foetal heartbeat, the administration of drugs to accelerate labour and instrumental delivery. The review, initiated by Portiuncula Hospital Ballinasloe-Saolta University Health Care Group, will be carried out by an independent expert team and will include a patient representative.
The Saolta Hospital Group said it is contacting the seven families affected and appointments are being made for consultations with medical staff and support services.
