Induction of general anesthesia for an elective operation should be delayed after breastfeeding by how many hours?

• A. 2 hours
• B. 4 hours
• C. 6 hours
• D. 8 hours

Answer: (B)

The main idea is to minimize the newborn’s exposure to any anesthetic drugs that might pass into breast milk. After general anesthesia, drugs used during induction and maintenance can be secreted into breast milk for several hours. Waiting four hours after the last breastfeeding before starting anesthesia gives enough time for those drug levels in milk to drop to negligible amounts in most healthy infants, reducing the risk of sedation or respiratory depression when breastfeeding resumes. Choosing two hours would risk higher residual levels in milk, while six or eight hours is longer than necessary for standard cases and can disrupt scheduling. If the infant is premature, ill, or if long‑acting opioids were used, longer precautions may be warranted, but for typical elective cases the four‑hour guideline is appropriate.
