Postpartum Problems Flashcards
What is puerperium?
The puerperium is a period of repair and recovery after birth where tissues return to their nonpregnant state
How long does puerperium normally last?
6 weeks post-partum on average
What colour is the discharge 3-4 days post partum?
Fresh red
What colour and consistency is the discharge 4-14 days post partum?
Brownish-red and watery
What colour is the discharge 10-20 days post partum?
Yellow
What uterine changes occur during the puerperium?
- The endometrial lining of the uterus rapidly regenerates by day 7
post-partum - The fundus of the uterus returns to its physiological location within the pelvis by around 2 weeks.
-uterine weight decreases
What is colostrum?
This is the first
milk a breastfed baby receives and is more protein and vitamin rich than later milk produced by
the mother. Colostrum is essential for early immunological protection to the newborn.
What causes the initiation of lactation?
y expulsion of the placenta in stage 3 of labour as well as a decrease in
oestrogen and progesterone levels
What is the let-down reflex and how does it work?
The let-down reflex refers to the mechanism of milk release from the breast during feeding.
In response to suckling (or alcohol, pain, the cry of a baby), oxytocin is stimulated and released from the posterior pituitary which in turn stimulates the myoepithelial cells which surround the breast alveoli to contract which squeezes breast milk out of the breast alveoli and nipple
What hormone is primarily responsible for the production of breast milk?
Prolactin
What hormone is primarily responsible for the release of breast milk?
Oxytocin
How long , according to the WHO, should exclusive breastfeeding occur?
The World Health Organisation (WHO) recommends exclusive breastfeeding for the first six
months of an infant’s life
What is the most common reason women stop breastfeeding? What is this usually due to?
Insufficient milk. The main reasons as to why milk won’t eject as effectively are ineffective attachment and infrequent feeding
What is the most common cause of lactational mastitis?
Infective from Staphylococcus aureus
what are the most common causes of non-infective mastitis?
Duct ectasia (blocked lactiferous duct) or foreign body such as a piercing.
How can improper breastfeeding technique lead to lactational mastitis?
Trauma to the breast and subsequent milk stasis and ineffective milk release make the breast
more likely to harbour bacteria and therefore be more prone to infection.
Where is the most common site for a breast absess in someone who is breastfeeding? And in a non-breastfeeding person?
Breastfeeding = peripheral breast
Non-breastfeeding = sub-areolar
What topics should be included in a focused breast history in someone with suspected mastitis?
- Milk stasis (decreased milk output)
- Possible abscess (tender lump)
- Symptoms related to possible breast inflammation (e.g., warmth, pain, swelling,
firmness, erythema) - Nipple discharge, which may be present with mastitis and occurs more often with duct
ectasia (dilated ducts with inflammation); however, purulent discharge is usually
indicative of breast infection - Systemic symptoms of infection (fever, malaise, myalgia)”
What is the treatment for lactational mastitis?
Flucloxicillin 7 days and continue to breastfeed
What is the definition of post partum haemorrhage?
blood loss equal to or exceeding 500ml after the
birth of the baby
What is the difference between primary and secondary PPH?
If the bleeding occurs within 24 hours of delivery this is referred to as Primary
PPH, whereas if the bleeding occurs from 24 hours to 6 weeks post-delivery, this is therefore
Secondary PPH.
What volume of blood loss is associated with a minor PPH? And a major PPH?
Minor = 500-1000ml blood loss Major = >1000ml OR Signs of cardiovascular collapse OR ongoing bleeding
What are the causes of PPH?
4Ts:
- Tone (70%): Uterine atony
- Trauma (20%): Vaginal tear, cervical laceration, rupture
- Tissue (10%): Retained Products of Conception
- Thrombin (<1%): Coagulopathy
What are the antenatal risk factors for PPH?
- placental probelms (praevia, abruption)
- past obstetric history of retained placenta, C-section, PPH
- multiple pregnancy
- obesity
- polyhydramnios
- foetal macrosomia
