1. The nipple should be cleaned after breastfeeding.
If the nipple is broken and chapped, it should be promptly treated. Pay attention to the oral hygiene of the baby and promptly treat its oral inflammation.
2. Avoid milk deposition, prevent nipple damage, and keep it clean.
Nipple retraction can often squeeze, pull correction.
3. Develop regular breast-feeding habits that do not allow babies to sleep with nipples.
Every time you suckle, you should suck the milk and if there is silt, you can use a breast pump or massage to help discharge the milk.
4. Eat less irritating foods such as onions, ginger, and garlic.
Chinese medicine believes that acute mastitis is due to the presence of heat and toxic heat. Therefore, you should eat less hot food on the diet to avoid getting sores.
5. The nipples should be kept clean during breastfeeding, and the milk should be sucked empty at the end of each feeding period.
If you do not breathe or have a feeling of milk bloating, use a hand squeeze or empty with a breast pump. Milk deposition is an important factor in causing mastitis and it is important to keep the milk open.
6. Should often self-massage.
Maternal mothers must develop the habit of breast massage. Method: Hold the breast in one hand with a hot towel, and place the other hand on the upper side of the breast. Turn the massage clockwise. If the breast feels painful or if there is a lump on the breast, the technique can be heavier. While self-massaging, the breast can be squeezed a little harder, and the milk is squeezed out of the nipple. After several repetitions, the breast tube is smooth. Massage once a day for 15-20 minutes.
Polyhydroxyalkanoates (PHAs) comprise a group of natural biodegradable polyesters that are synthesized by microorganisms. However, several disadvantages limit their competition with traditional synthetic plastics or their application as ideal biomaterials. These disadvantages include their poor mechanical properties, high production cost, limited functionalities, incompatibility with conventional thermal processing techniques and susceptibility to thermal degradation. To circumvent these drawbacks, PHAs need to be modified to ensure improved performance in specific applications. In this review, well-established modification methods of PHAs are summarized and discussed. The improved properties of PHA that blends with natural raw materials or other biodegradable polymers, including starch, cellulose derivatives, lignin, poly(lactic acid), polycaprolactone and different PHA-type blends, are summarized. The functionalization of PHAs by chemical modification is described with respect to two important synthesis approaches: block copolymerization and graft copolymerization. The expanded utilization of the modified PHAs as engineering materials and the biomedical significance in different areas are also addressed.
