Dr Sanjay Gupta is CNN’s chief medical correspondent, but also a practising neurosurgeon. This means that during CNN’s coverage of the Haitian earthquake and its aftermath Gupta has been reporting from the field, but also filmed performing surgery and working in an emergency medical clinic.

Today’s Connect the World show on CNN will explore the issues this raises from whether journalists can/should be part of a story to whether Gupta can carry out his role as a doctor and a journalist at the same time without undermining either position. The show airs at 9pm (GMT).
