Safety advocates want stricter legislation after child's death at Fort Worth dental office

Activists are looking at a child's death at a Fort Worth dental office earlier this year and hoping it spurs the state to pass stricter legislation to make sure such tragedies never happen again.Investigators determined Chrishelle Hemphill, 48, was responsible for the April death of 4-year-old Aithana Rodriguez-Arriaga at Cuddle Kids Dental in Fort Worth, and her arrest affidavit details a series of errors in the child's death.The affidavit states Rodriguez-Arriaga did not wake up following a procedure on her tongue performed by Hemphill on Apr. 1. An unusually high amount of meperidine (demerol, an opiate) was found in the child's blood system, which a medical examiner said would have been toxic for an adult.Rodriguez-Arriaga was also given chloral hydrate, which the Texas State Board of Dental Examiners says has been discontinued and has no specific reversal agent.After finding Rodriguez-Arriaga unresponsive, Hemphill gave her Flumazenil, the wrong reversal agent, instead of Narcan.H
