Halothane is no longer available in the United States. There is no published experience with the therapeutic use of halothane as an anesthetic during breastfeeding, but trace amounts were found in the milk of a practicing anesthesiologist who had administered halothane in the operating room. Various recommendations have been made regarding breastfeeding after halothane anesthesia, from discarding the first pumping after recovery to discarding breastmilk for 24 to 48 hours after the surgical procedure.[1,2] Although withholding breastfeeding for 24 h is probably unnecessary, a short-acting anesthetic is preferred. In one study, breastfeeding before general anesthesia induction reduced requirements of sevoflurane and propofol compared to those of nursing mothers whose breastfeeding was withheld or nonnursing women.[3] It is possible that requirements for other anesthetic agents would be affected similarly.
