The lawyer for a Sydney ICU nurse accused of hooking his wife up to a sedative has told a judge there's no evidence her life was endangered.
Ugendra Singh, 45, was arrested in May and charged with using poison so as to endanger life, possess prescribed restricted substance, larceny and common assault.
After being refused bail in the Local Court, Singh made another application in the NSW Supreme Court on Tuesday.
Police have alleged he administered "what he said was a saline drip" to his wife Joykita Lata on the morning of May 5 "due to concerns the 38-year-old woman was dehydrated".
Ms Lata, also a nurse, became unconscious at their home at Hebersham in western Sydney and called police when she woke eight hours later.
Her husband is accused of giving her propofol, a sedative drug which he allegedly stole from his workplace.
In arguing for bail on Tuesday, his lawyer Paul McGirr said there was nothing in the evidence to indicate Ms Lata's life was endangered.
The prosecutor has submitted the charges may be revised and more serious ones may be laid after the receipt of a toxicology report.
But Justice Geoffrey Bellew said he had to decide the bail application based on the current charges.
"I cannot speculate what may or may not be in the toxicology report," he said.
"I am very troubled by the fact the officer in charge has said that report could be as long as four months away."
If it took four months, that would mean Singh would have been in custody for almost seven months before the brief of evidence was served which gave rise to "the significant question of delay".
Mr McGirr said if granted bail, Singh would be able to care for his elderly parents and live with them now his job has been suspended.
Justice Bellew said he would give his decision on Friday.
