A Louisiana hospital has said it has found a patient who was prescribed fentanyl in the hospital’s internal medicine department, killing him.

In a statement on Monday, the New Orleans Health Department said Dr. Nicole Dominguez-Gonzalez, who had been employed there since 2014, was treated for a fatal overdose of fentanyl and later died at a hospital.

“We are deeply saddened by the loss of our colleague Dr. Domingez-Gombau, who was our resident in the ICU at Saint Francis Hospital in Baton Rouge.

She was a dedicated and highly professional colleague who helped patients by sharing information, advising, caring and serving,” the statement said.

The statement did not provide a date for Domingz-Gonzo’s death.

Her death is the second to occur at the hospital since October, when a nurse was found dead.

She died of an apparent drug overdose.

The hospital said it was cooperating with the investigation.

In February, another nurse was hospitalized after being prescribed fentanyl.
