Hand Expression of breast milk

Hand expression of breast milk

There are many ways of expressing milk from breast. Breast pumps are very commonly used these days. However in my experience, working as a breast feeding counselor, I found most, if not all, pump devices to be very difficult for mothers to use. This was especially so because it caused a lot of discomfort and pain.

The mothers whom I have taught hand expression technique have all told me that it is virtually pain-free and more effective than mechanical pumps. None of them went back to using mechanical devices.

The structure of the breast
I will discuss the structure of the breast that is important from the point of view of hand expression technique. I will be referring to the diagram below during the discussion.

For the sake of discussion I will divide the breast in to 3 parts.

• The first part, the nipple, is the outlet for the milk produced within the breast. At the tip of the nipple are the openings of the milk ducts through which the milk leaves the breast.
• The second part is the areola. This is the darker pigmented (coloured) area of the breast just around the nipple. Beneath this part of the breast are the lactiferous sinuses, which are the collecting areas, where the milk is stored after production. Also very important to note here is that the skin of the areola is relatively pain insensitive (because it has very little pain receptors).
• The third part is the rest of the breast tissue. This is the largest part of the breast. Under the relatively less pigmented skin of this part of the breast are the many glands that produce the breast milk. The glands are supported by fat and connective tissue that make up the bulk of the breast itself. Note in the diagram above the detail of the milk secreting glands (shown enlarged, inset). There is a layer of muscle (very thin) around the milk secreting cells. These muscles contract in response to the hormone Oxytocin to squeeze the glands to push the milk into the lactiferous sinuses via the ducts.

Preparing to hand express breast milk

• Get clean (preferably sterilized) container to express the milk into. A wide mouthed cup or bowl would be most suitable.
• Wash hands well.
• Wipe clean the breast with a moist cloth. There is no need to wash the breast with soap or other cleaners.
• Stimulate the Oxytocin production.

How to stimulate Oxytocin production

Oxytocin is a hormone produced by the brain that helps “let down” the milk. As described above, it helps contract the muscle layer around the milk producing glands to push the milk into the lactiferous sinuses. Self confidence and comfort for the mother are essential to effective hand expression of milk. Lack of these causes the brain to decrease the production of the essential hormones.
There are many ways in which Oxytocin production can be increased just before starting hand expression.

• Close contact with the baby like cuddling can increase production of Oxytocin.
• Massaging the breast and the nipple increases Oxytocin production. Massaging the breast gently towards the nipple (not squeezing) is very effective. Another techniques described is “combing” the breast gently towards the nipple using the tips of the fingers or a non-sharp comb.
• Back massage over the back of the chest on either side of the spine is also an effective way of increasing Oxytocin production.
• But perhaps the most effective way to increase Oxytocin production is to allow the baby to suckle on the other breast. Many mothers have themselves noted milk flowing from one breast when baby is feeding on the other. This demonstrates the strength of the Oxytocin effect.

How to hand express breast milk

1. Sit or stand comfortably with the bowl or cup placed in a position that will help catch the milk.
2. Use right hand for left breast and vice versa.
3. Place the thumb on the areola above the nipple and the index finger on the areola below the nipple as shown in the diagram (figure 11.a) below. The pulp of the finger and thumb will be in contact with the skin of the areola, not the nipple or the rest of the breast. This is very important.
4. Holding the fingers in the position described above, push the fingers into the breast towards the chest wall. When this is done, the areola will be held between the thumb and the index finger (the nipple will no longer be between the fingers).
5. Now squeeze the areola between the thumbs and the index finger (Figure 11.b). The lactiferous sinuses underneath the areola will feel like firm “rope” like structures. When squeezed the milk in them will be pushed towards the tip of the nipple. Please note that the areola is relatively pain insensitive and so this should not cause pain. If, however, the nipple or the breast outside the areola was squeezed it would be painful.
6. After squeezing, release the areola gently, making sure not to lift the fingers off the skin.
7. Leaving the fingers on the areola, allow the breast to return to its normal shape. This will allow the lactiferous sinuses to re-fill with more milk. The reason why the fingers are not lifted off the skin is to minimize “rubbing” action on the nipple and areola.
8. Now repeat steps 4 to 7. Note that the first couple of squeezes may not get the milk to flow out. Keep repeating the steps 4 to 7 and milk will begin to flow (maybe even squirt in jets).
9. The expressing should be done all around the areola not just with finger above and below nipple. It is important to rotate the fingers all around to ensure all segments of the breast are expressed.

What not to do during hand expression

• Do not slide the fingers on the skin during squeezing and releasing phases of expressing milk.
• Pressing or pulling the nipples does not express milk. Remember there is no milk within the nipple itself.
• Do not pull the fingers forward with the squeezing phase of expressing. This does not help express milk. Just simple squeezing of the areola between the two fingers without pulling forward is most effective.
• Do not press or squeeze the breast itself. This does not help express milk. Remember again that the milk is stored within the lactiferous sinuses under the areola. With a good Oxytocin production the milk within the breast itself gets forced into the lactiferous sinuses by contraction of the muscle layer around the glands.
• Do not try to hurry expressing milk. It takes time to express large volumes of milk. Please also not that, the milk that comes out in the first few minutes of hand expression and that which comes out towards the end is very different in composition. The latter part contains most of the protein and fats that are vital for the baby. So take time, around 20-30 minutes, to try to empty the breasts to ensure that the collected milk contains all the vital nutrients. Switch over to the opposite side after about 5 minutes of expressing one breast and repeat alternately.
  

If you feel pain during hand expression, it is most likely because of incorrect technique. Check and make sure that you are not squeezing the nipple or skin outside of the areola.

Because the nipple is not pressed during hand expression, this method can be used in mothers who are unable to breastfeed because of cracked nipples.

Your question: breastmilk storage

Your question:
I would like to countinue feeding my baby with breastmilk even when I return to work. I have just learnt how to express milk by hand (thanks to a couple of nurses at IGMH). Can you tell me how long I can store the milk?

My Answer:
Breastmilk can be stored for upto 8 hours at room temperature, 24 hours in a refrigerator and upto a month in a freezer.

Milk that is stored in the refrigerator or the freezer should not be heated as this would destroy the very useful bio-active substances in the milk (protective substances). It should be slowly thawed or brought to room by leaving it at room temperature or by immersing the container in a bowl of luke warm (not hot) water.

I think hand expression of breastmilk, when properly done, is one of the best and more importantly a pain-free way of expressing milk. I would very strongly recommend that every mother learn the proper technique for hand expression of breastmilk.

I will discuss technique in a bit more detail later.
