Jean Huang died following a botched breast augmentation procedure. Now the 'doctor' has been jailed.

Jean Huang was 35 years old when she underwent a banned breast augmentation procedure at a Sydney beauty clinic. Two days later, she died in hospital, having been declared brain-dead from an overdose of local anaesthetic lidocaine administered during the procedure.

For over six years, Huang's family have been left devastated, waiting for justice. This week the 'doctor' who performed the procedure was finally jailed.

It was August 30, 2017, when Huang underwent the procedure at the Medi Beauty Clinic in the inner-city Sydney suburb of Chippendale, which she operated and part-owned. 

She opted for an augmentation that involved injecting hyaluronic acid filler into her breasts, which was not approved in Australia at the time. 

Jie Shao, a 40-year-old Chinese national, had flown into Sydney from Melbourne days earlier to perform the procedure.

Despite holding a bachelor's degree in medicine, Shao was not a registered medical practitioner in Australia.

After Huang died, Shao was charged with manslaughter, which Shao denied. She pleaded guilty to the lesser charge of recklessly administering poison endangering life. 

At the three-week trial, the court was told that Huang was conscious for most of the breast enhancement procedure. She was given the painkiller tramadol via an IV drip, incisions were made in her breasts, then syringes of lidocaine were administered. 

The court heard Huang began twitching, having convulsions and foaming at the mouth. 

The prosecution said, despite this, Shao continued to inject the fillers.

"Jean Huang is out cold, and she is still pumping the remaining fillers into her," the prosecutor said.

Huang then suffered a heart attack and was rushed to hospital - there was no resuscitation equipment available in the  clinic. Two days later, on September 1, 2017, Huang was declared brain-dead and her life support was switched off.

Her cause of death an overdose of local anaesthetic lidocaine.

In her closing address, the prosecutor said Shao "repeatedly misrepresented herself as a doctor".

After less than a day of deliberations, the jury found Shao guilty of manslaughter. 

A term of full-time imprisonment is "realistically inevitable", the judge said. Her sentencing hearing will be in May.

Huang's husband told the court his wife had brought light to his life but now the only time he feels comfortable is in his dreams.

"I was there when my wife's surgery [when the] accident happened ... the doctor told me 'It's just a small injection, she is still breathing', but after three days, my hope for our life was breaking down," he said.

"Every day, I will miss the bit of living with my wife together ... I still wish she can respond to me even just one more time."

He said the only thing he could hope for now is a "fair judgement" with "reasonable punishment".
