A Texas physician was suspended and arrested after officials say he tampered with IV bags, causing serious cardiac complications and one death.

The U.S. Department of Justice said in a news release that Dr. Raynaldo Rivera Ortiz Jr. is accused of injecting nerve-blocking agents and other drugs into patient IV bags. He was arrested Wednesday and charged with tampering with a consumer product causing death, and intentional drug adulteration.

The cardiac incidents reported by the DOJ happened during the time Ortiz worked at the Baylor Scott & White Surgicare North Dallas facility, from May through September 2022.

None of the cardiac complications occurred during Ortiz’s surgeries, but they started two days after Ortiz found out about a “disciplinary inquiry” involving an incident where he allegedly “deviated from the standard of care” during an anesthesia procedure.

Ortiz has a history of disciplinary actions against him, the DOJ said.

Some physicians allegedly heard Ortiz say the center was trying to “crucify” him.

According to the DOJ, most of the incidents happened during longer surgeries that used more than one IV bag taken mid-surgery from a stainless steel bag warmer.

Officials said Ortiz was captured on surveillance video putting IV bags into the warmer shortly before patients began experiencing cardiac emergencies.

In one instance, agents saw him walking quickly from an operating room to a bag warmer, place a single IV bag inside, look around the empty hallway and quickly walk away. A little over an hour later, a 56-year-old woman suffered a cardiac emergency during a scheduled cosmetic surgery after a bag from the warmer was used during her procedure, the DOJ said.
