Nashville hospital medication error leaves at least 1 patient paralyzed after routine surgery, 3 others hurt

Four patients getting routine joint replacement surgeries at a hospital in Nashville allegedly had the wrong drug injected into their spines, leaving at least one woman paralyzed, according to her family.

Ascension Saint Thomas Hospital Midtown in Nashville on Friday acknowledged a " medication error " in its pharmacy that led to the patients being injected with potassium phosphate instead of a regular anesthetic and experiencing "adverse health reactions," according to multiple reports.

The Tennessee Bureau of Investigation confirmed to Fox News Digital Saturday that it is investigating the incident after receiving information Friday from the Tennessee Healthcare Facilities Commission.

It was supposed to be bupivacaine, and it was potassium, and we don’t know what quantity." Dorton said her mother-in-law has no feeling from her breastbone down.
