The Usefulness Of A Preoperative Pregnancy Questionnaire In Determining The Need For Pregnancy Testing Prior To Anesthesia

Abstract

Background: Many physicians require pregnancy testing before anesthesia despite no evidence that anesthetics in clinical concentrations are teratogenic. This approach is costly and does not follow current recommendations. The authors designed a preoperative pregnancy questionnaire to determine the likelihood of pregnancy. The goal was to determine if an assessment based on history would help decrease needless preoperative tests. Methods: Patients (n=216) 13-56 yrs completed the questionnaire and underwent urine pregnancy testing prior to surgery. The questionnaires were reviewed to determine if pregnancy testing was indicated. Results: Twenty-one patients needed pregnancy testing based on their histories. The testing yielded one positive result that was predicted based on history. Conclusions: A questionnaire is useful for the anesthesiologist when determining the need for preoperative pregnancy testing. A history is the backbone of medicine, and should guide preoperative testing. This would streamline the preoperative process, while maintaining vigilance.
