Hugh Pickens writes: "In hospitals around the country nurses connect and disconnect interchangeable clear plastic tubing sticking out of patients' bodies to deliver or extract medicine, nutrition, fluids, gases or blood — sometimes with deadly consequences. Tubes intended to inflate blood-pressure cuffs have been connected to intravenous lines leading to deadly air embolisms., intravenous fluids have been connected to tubes intended to deliver oxygen leading to suffocation, and in 2006 a nurse at in Wisconsin mistakenly put a spinal anesthetic into a vein, killing 16-year-old who was giving birth. "Nurses should not have to work in an environment where it is even possible to make that kind of mistake," says Nancy Pratt, a vocal advocate for changing the system. Critics say the tubing problem, which has gone on for decades, is an example of how the FDA fails to protect the public. "FDA could fix this tubing problem tomorrow, but because the agency is so worried about making industry happy, people continue to die," says Dr. Robert Smith.""
