Exposure to organic solvents. Does it adversely affect pregnancy?

QUESTION: One of my patients is a laboratory technician who routinely handles organic solvents. She has just learned that she is pregnant, and she depends very much on this job because her husband is unemployed. What is the risk to her unborn baby? ANSWER: Available epidemiologic data indicate your patient's fetus might be at increased risk for malformations. We recommend that she minimize her occupational exposure to organic solvents by routinely using ventilation systems and protective equipment. This is most important during the first trimester of pregnancy.
