A mother is suing a gynaecologist, a paediatrician and a hospital over their alleged failure to detect that her baby would be born with a severe heart condition. Tsui Shiu-chung claims that she had been assured that her son, Chan Arm, who is now six years old, was in good condition after his birth, and they were both discharged from Hong Kong Central Hospital on June 12, 1991. But when they returned home the baby's limbs turned blue and he was incapable of sucking milk, according to the writ. Later that month doctors at another hospital diagnosed the child as suffering from a grave heart disease. The baby then needed 10 months of intensive treatment, which led to Ms Tsui suffering great mental distress and hardship, the writ added. Eric Lee, a gynaecologist at Prince's Building, J. T. N. Chung, a paediatrician at Swire House, and the Hong Kong Central Hospital, Lower Albert Road, are accused of negligence.
