'A mistake was made': defence

The Clarks brought their son to the hospital on Nov. 28, 2013.John hadablistering rash covering more than 70 per cent of his body and four of histoes were black with gangrene.

"I'm going to suggest you to that a mistake was made in this case," said Chow, who went onto say the boy's saline levels were increased too quickly.

But Mahoney disagreed: "Our priority was saving his life and treating his shock, which was his most immediate, life-threatening condition."

The boy was in septic shock, suffering multiple organ failure and ultimately died from a staph infection 21 hours later, jurors heard.

'We chose to save his life'

On Tuesday, Mahoney testified John was"absolutely, critically ill" and said she was worried he wastoo sick to survive the infection that was attacking his organs.

John suffered a seizure within an hour of arriving at the children's hospital, which Chow suggested was caused by staff increasing John's saline levels too quickly.

The baby's saline levels were 108millimoles per litre when he arrived. Before the seizure, John's saline levels had been raised by sevenmillimoles, which was still well below the normal range for a baby.

Normal range is 133 to145 millimolesper litrebutMahoney agreed it isdangerous to overcorrect a person's levels in a short period of time. The doctor did note overcorrection would only be a serious concern in patients who suffered chronic dehydrationor had been dehydrated for a long period of time.

We chose to save his life at the expense of his sodium levels,there was no other way to do it," said Mahoney.

Baby died of staph infection

Within 21 hours of arriving at hospital, John suffered a second cardiac arrest and died.

John died of a staphylococcus infection, which he would have survivedhad he been treated sooner, according to the doctor.

Prosecutors Shane Parker and Jennifer Crews told jurors they will also hear evidence the baby was suffering from malnutrition that compromised his ability to fight off infection.

Chowasked if Mahoney hadconcerns thatAlberta Children's Hospital might have "significantly contributed to John dying."

"No," Mahoneyresponded.
