He was also banned from ever practising medicine again.
A lawyer from the firm representing him, Ornella Spatafora, said Pechier would appeal.
During the more than three-month trial, prosecutors called for Pechier to be jailed for life, saying he “used medicine to kill”.
They said he contaminated IV bags with potassium, local anaesthetics, adrenaline and even an anticoagulant to trigger cardiac arrest or haemorrhaging in patients being treated by colleagues.
His goal, prosecutors said, was to “psychologically hurt” caregivers with whom he was in conflict and to “feed his thirst for power”.
‘End of a nightmare’
Civil parties welcomed the verdict.
“It’s the end of a nightmare,” said Sandra Simard, who survived a cardiac arrest during back surgery aged 36. A dose of potassium 100 times higher than normally prescribed was found in her rehydration pouch.
“Now we can have a quiet Christmas,” said Jean-Claude Gandon, who was poisoned during a urology operation aged 70 while Pechier was his anaesthetist.
An investigation was launched in 2017 after suspicious cardiac arrests were recorded during operations on patients considered low risk.
Pechier had argued during the probe that most of the poisonings were down to “medical errors” by his colleagues.
He admitted during the trial that there had been a person poisoning patients in one of the two clinics where he worked, but said it was not him.
“I am not a poisoner,” he said.
One colleague described Pechier as a very good doctor with an “oversized ego”.
The verdict comes after a court in May sentenced retired doctor Joel Le Scouarnec to 20 years in prison after he confessed to sexually abusing or raping 298 patients, most of them children, between 1989 and 2014.
That case raised questions about how he was allowed to continue practising until retirement despite at least one colleague sounding the alarm.
