摘要：

The combination of tetracaine, adrenalin, and cocaine (TAC) has become increasingly popular as a topical anesthetic for the suturing of simple skin lacerations. The purpose of this study was to determine the effects of TAC on a urine drug test for cocaine. On the morning after the use of TAC, 14 of 18 patients (78%) studied had positive screening tests for benzoylecgonine (cocaine metabolite) by the enzyme multiple immunoassay test (EMIT®) method. All specimens also were analyzed by gas chromatography and mass spectrometry, the references standard for analysis of drugs of abuse in urine, and 15 of the specimens (83%) were positive. Four of 18 positive specimens (22%) still had positive EMIT® drug screens on the morning of the next day, an average of 36 hours after use of TAC. We recommend that physicians who use TAC solutions as a local anesthetic caution their patients that they may fail a urine drug screen for cocaine if they are tested within 36 to 48 hours of the administration of the use of TAC. © 1990 American College of Emergency Physicians.
