The quantities of propofol found in breast milk are exceedingly minute and are unlikely to be absorbed by the infant. The prevailing recommendation suggests that breastfeeding can be resumed once the mother has sufficiently recovered from general anesthesia to nurse, and there is no necessity to discard milk.
Like propofol, Ketamine and its active metabolite, norketamine, are present in breast milk in minimal concentrations, and their oral bioavailability is limited, suggesting a low risk to breastfed infants. Current data suggest that the use of ketamine in nursing mothers is unlikely to impact the breastfed infant or lactation. However, until additional data are obtained, ketamine should be administered with vigilant monitoring of the infant for signs of sedation, poor feeding, and inadequate weight gain.
The quantities of etomidate detected in breast milk, like the others, are minimal and diminish swiftly.
Current data suggest that no waiting period is necessary before resuming breastfeeding following administration of etomidate. Mothers can safely resume breastfeeding once they have sufficiently recovered from general anesthesia to nurse.
In summary, prevalent anesthetic sedatives administered during anesthesia are considered safe for infants breastfeeding from mothers undergoing sedation. When employing a blend of anesthetic agents for a procedure, adhere to the guidelines pertaining to the most concerning medication utilized during the process. Always monitor the infant for signs of sedation, inadequate feeding, and suboptimal weight gain.
| Agent | Transfer into breast milk | Breastfeeding guidance |
|---|---|---|
| Propofol | Exceedingly minute quantities, unlikely to be absorbed by the infant | Resume once the mother has recovered enough from general anesthesia to nurse; no need to discard milk |
| Ketamine (and norketamine) | Minimal concentrations with limited oral bioavailability | Unlikely to affect the infant or lactation; monitor the infant for sedation, poor feeding, and inadequate weight gain |
| Etomidate | Minimal amounts that diminish swiftly | No waiting period; resume once recovered enough to nurse |
| Inhalational agents | Clinically insignificant; breastfeeding can resume once the mother is awake and alert | Widely regarded as safe for maintenance owing to swift elimination |
| Xenon | Not detected in breast milk at any time in limited research | Ideal gas for the breastfeeding patient, though not available in the United States |
