Why have I been asked to stop breastfeeding?Ìý

The clinical team looking after you have decided you need a Nuclear Medicine Lung Perfusion Scan. The scan involves giving you a radioactive injection which enters your bloodstream and allows us to look at your lungs. This means that some of the radioactive particles in the injection can pass into your breastmilk. So, if you were to continue to breastfeed your baby after the scan, your baby would receive an undesirable dose of radiation.ÌýÌý

How long do I need to stop breastfeeding?Ìý

You will be asked to stop breastfeeding for 13 hours. You may wish to express and store some milk before the scan.ÌýÌý

Ìý

Expressing during the interruption periodÌý

Wherever possible, at least one feed should be expressed and appropriately stored in advance of the administration of isotope.ÌýÌý

The baby should be breastfed just before the administration.Ìý

3 to 4 hours after the administration of isotope, you should express as much milk as possible- this milk should be discarded and alternatives used instead. Please contact your midwife or GP for breast pump advice.Ìý

Breastfeeding should not be resume until after 13 hours post administration of isotope, milk should be regularly expressed as completely as possible and discarded.ÌýÌý

ÌýÌý

Feeding your baby during the interruption periodÌýÌý

During the time when you are unable to breastfeed due to your breast milk being radioactive from the injection, you can continue to give your baby breastmilk that you may have expressed previously and stored, or you can choose to use formula.Ìý

The time holding the baby when feeding should be limited to as small as time frame as possible and not cuddling during the 13 hours post procedure. It may be advisable that someone else could help feed during this time if possible.Ìý
