Parents of a 2-year-old girl involved in a drowning incident on Memorial Day have sued to stop Texas Children’s Hospital from testing if she’s brain dead, testing a new strategy in Texas’ “right to life” movement aimed at giving people as much access to life-supporting services as possible.While most fights to keep patients on life support begin after they’ve been given a brain death diagnosis, Annelise Camp’s parents are battling the hospital at an earlier stage, the testing phase. “This is not settled science,” said state Rep. Steve Toth, R-The Woodlands, who has helped drive the public’s attention to the Camps, who live in Cypress.Brain death is defined in Texas law as the irreversible cessation of brain function. Under the law, once a patient is declared brain dead, a hospital can withdraw life-sustaining measures. According to court documents, the Camps say Annelise shouldn’t be tested for brain death so she can have more time to recover. They also ask that she be transferred to another hospital to explore other treatment options. However, Texas Children’s has stated it wants to conduct testing to determine next steps in her medical care and that it has no imminent plans to end care for Annelise.
