What she needed to do was to perform a balloon pulmonary valvuloplasty-a tricky manoeuvre even in adults-forcing the valve to open. With babies this size…

She’d normally advise waiting, she thought bleakly. She’d normally advise keeping him on oxygen. She’d try and get him fitter, older. She’d operate at a few weeks.

To operate on such a newborn…

But this was no minor blockage.

‘Do you have the equipment?’ she asked. ‘I’d need to monitor catheters by fluoroscopy.’

‘I’d imagine we have all you need,’ Cal told her. ‘Simon, the cardiologist who’s just left, had the place well set up for heart surgery.’

Gina nodded. She’d worked with this service before, and she’d expected this answer.

Many of the population around Crocodile Creek would be indigenous Australians, and she knew from experience how reluctant they were to leave their people. For a tribal elder to come to Crocodile Creek for an operation would be hugely stressful, but here at least here they could still be surrounded by their own. To be flown to Brisbane, where there was no one of their tribe and no one spoke their language, was often tantamount to killing them. The cultural shock was simply too great for them to handle.

That would be part of the reason Crocodile Creek would be set up so well, she knew. This base would do surgery which would normally only be done in the big teaching hospitals. Death rates would be higher because of it, but the population would accept it. The doctors involved had to accept it.

But this doctor in particular didn’t have to like it.

‘So we have no paediatrician and no cardiologist.’
