Routine surgery turns into catastrophic medical error
November 12, 2026, 1:25 a.m. Central time.
A 78-year-old Tennessee grandmother who entered a Nashville hospital for an elective joint replacement procedure has filed a sweeping $150 million civil lawsuit, alleging that medical staff mistakenly injected an unbuffered, toxic electrolyte solution directly into her spinal canal and then waited more than ten hours to attempt a corrective procedure, leaving her permanently paralyzed.
The lawsuit, filed in Davidson County Circuit Court by attorneys representing Linda Gilbert, names Ascension Saint Thomas Hospital Midtown as the primary defendant. Gilbert was one of four orthopedic patients on the morning of August 14, 2026, who allegedly received contaminated or improperly prepared injections due to a systemic pharmacy compounding breakdown.
According to court filings, surgical staff intended to administer a standard spinal local anesthetic—typically mepivacaine or bupivacaine—to numb Gilbert from the waist down before her knee operation. Instead, pharmacy staff allegedly mislabeled and loaded vials of concentrated potassium phosphate, a potent electrolyte solution that is lethal or neurotoxic when injected directly into neural pathways.
Warning signs dismissed under general anesthesia
The civil complaint outlines a harrowing sequence of events in the pre-operative suite. Immediately after receiving the spinal injection, Gilbert reportedly cried out in agony, informing the surgical team of excruciating, burning nerve pain spreading down both legs.
Rather than halting the procedure, verifying the administered drug, or consulting hospital pharmacy leadership, surgical personnel allegedly administered general anesthesia, rendering Gilbert unconscious, and proceeded with the routine knee replacement. Gilbert was the third patient to undergo surgery that morning using the tainted medication batch, yet operating room teams reportedly failed to halt surgical schedules until multiple patients began exhibiting severe neurotoxic symptoms in post-operative recovery units.
Even more damning, the lawsuit alleges that Ascension Saint Thomas clinicians waited more than ten hours after the erroneous injection before performing a recognized spinal washout irrigation to flush the caustic electrolyte solution out of Gilbert's thecal sac. By that time, permanent spinal cord ischemia and necrosis had set in, permanently depriving Gilbert of voluntary motor function and sensory feeling below her chest.
