A former nurse accused of injecting her sick daughter with urine and poisoning her with laxatives has been found not guilty.

Prosecutors had alleged the 47-year-old, who cannot be named, injected urine into her immune-deficient daughter’s central venous line while the girl was in Sydney’s Westmead Hospital for acute renal failure in March 2015.

The woman, from NSW’s Hunter region, was also accused of twice using laxatives to poison with intent to injure her daughter in 2014.

The girl had a genetic immune deficiency and had been regularly hospitalised with unexplained diarrhoea and renal failure.
