The contractor had spent some time optimizing the process and the isolation of the product, scaling up as they went, up to a 10 litre scale.
Investigations turned up nothing--until a team of chemists from a nuclear weapons lab got involved. They shot through two sets of double glass doors, veered to their left, and parked her in a small curtained space marked trauma room one. The woman, clad in shorts and a T-shirt, was awake, but she responded to questions with only brief and sometimes incoherent utterances.
She was taking shallow, rapid breaths. Her heart was beating too rapidly to allow its chambers to fill before they pumped, so her blood pressure was plummeting.
The only thing unusual about her was her age, recalls Maureen Welch, a respiratory therapist who was assisting in the trauma room that night. Most patients who show up in an emergency room with such symptoms are elderly people, Welch says.
This woman, the paramedics reported, was 31 years old and had cervical cancer. Her name was Gloria Ramirez. The medical staff hovering over Chemical reaction report injected her with a host of fast-acting drugs that were part of the standard protocol for her condition: Valium, Versed, and Ativan to sedate her, and agents such as lidocaine and Bretylium to quell her aberrant heartbeat.
When it became clear that Ramirez was responding poorly to treatment, the staff tried to defibrillate her heart with electricity.
As the syringe filled, Kane noticed a chemical smell to the blood. Welch sniffed the syringe and smelled something, too: I thought it would smell like chemotherapy, the way the blood smells putrid when people are taking some of those drugs.
Instead, Welch says, it smelled like ammonia. She passed the syringe to Julie Gorchynski, a medical resident who noticed unusual manila-colored particles floating in the blood--an observation echoed by Humberto Ochoa, the doctor in charge of the emergency room, who was helping treat Ramirez.
Kane turned toward the door of the trauma room and swayed. Ochoa lunged for Kane, caught her, and gently guided her limp body to the floor.
Kane said that her face was burning, and she was put on a gurney and taken from trauma one. Gorchynski too began feeling queasy. A staff member asked Gorchynski if she was okay, but before she could respond she slumped to the floor. She was now the second member of the Riverside emergency room staff being wheeled away from the trauma room on a gurney.
Gorchynski shook intermittently; over and over again she would stop breathing for several seconds, take a few breaths, then stop breathing again--a condition known as apnea.
Meanwhile, back in trauma one, Welch became the third to succumb. I remember hearing someone scream, Welch says. It also triggered one of the most extensive investigations in forensic history--medical detectives from ten local, state, and federal outfits examined dozens of potential culprits, from poisonous sewer gas to mass hysteria.
So far, all the suspects have beaten the rap, except for one extraordinary hypothesis: After Welch collapsed, several other staff members began to say they felt ill, and hospital administrators declared an internal emergency.
Ochoa ordered the staff to evacuate all emergency room patients to the parking lot outside the hospital. Her blood pressure continued to drop, and her pulse was growing fainter. Ochoa and three others repeatedly administered electric shocks and drugs, but their efforts to stabilize Ramirez failed.
Two staff members moved the body to an isolation anteroom adjacent to trauma one. Outside, in the parking lot, hospital staff were treating patients and ill colleagues under the dull orange glow of sulfur lamps.
Because of concern that the stricken staff had been felled by a noxious chemical, they were stripped down to their underwear, and their clothes were bundled into plastic bags. Gorchynski continued to experience tremors and apnea.
Kane flailed her arms and kicked, and her face still burned. Soon she was in such bad shape that she too was laid out on a gurney. In all, 23 of the 37 emergency room staff members experienced at least one symptom.
Five were hospitalized for the rest of the night. Balderas endured bouts of apnea during a ten-day hospitalization.Sodium Hydride / DMF process stopped Scenario.

Analysis of a Toxic Death A year ago two dozen emergency room staff were mysteriously felled by fumes emanating from a dying young woman.

Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
