At the Maternity Unit in Romford's Queen's Hospital, bed seven has been joined by first-time mum-to-be Shola, who is 49 years old and expecting triplets. She is considered a high-risk pregnancy because of her age and because of it being a multiple birth. At Birmingham's Queen Elizabeth Hospital, 44-year-old Lisa is having a new battery fitted to her pacemaker. At Newcastle's Royal Victoria Infirmary, 65-year-old David has been rushed in with suspected sepsis. In the Great North's Children's Hospital, bed 27 is expecting a four-year-old who has recently been extremely ill. Parents Sarah and Mark have rushed young Thean to the emergency department with stomach pain. Less than a month ago he suffered a life-threatening bowel blockage, and they are worried that the same thing has happened again.
