An anaesthetist has been given a 190-year prison sentence after injecting bupivacaine, adrenaline and other drugs to IV saline bags, resulting in cardiac emergencies and another doctor’s death.

After injecting the bags with the drugs, prosecutors said Dr Raynaldo Riviera Ortiz Jr would then place them in a warming bin and wait for the bags to be used in surgeries performed by his colleagues, knowing their patients would experience dangerous complications.
