Breastfeeding - methods to suppress lactation
stop the lactation reflex i.e. stop suckling/expressing
supportive measures: well-supported bra and analgesia
cabergoline
Minor problems during breastfeeding
- Nipple pain - poor latch
- Blocked duct
Causes nipple pain when breastfeeding
Breastfeeding should continue
Give advice about the positioning of the bab
Breast massage - Nipple candidiasis
Treatment:
Miconazole cream for mother
Nystatin suspension for baby
Mastitis management
Affects 1 in 10 breasfeeding women
Treat if
- Systemically unwell
- Nipple fissure present
- symptoms do not improve after 12-24h of effective milk removal
- culture indicates infection
- Flucloxacillin for 10-14 days
- Breastfeeding/expressing should continue during the treatment
If mastits remains untreated –> breast abscess development –> incision + drainage
What is breast engorgement?
One of the causes of breast pain in breastfeeding women
Occurs in the first few days after birth
Almost always affects both breasts
Pain/Discomfort worse just before a feed
Fever - settles within 24h
Red breasts
Milk tends to not flow well from an engorged breast –> infant may find it difficult to attach + suckle
Complications of breast engorgement
Blocked milk ducts
Mastitis
Difficulties breastfeeding
Milk supply
Mx of breast engorgement
Hand expression of milk
Describe the symptoms of Raynaud’s disease of the nipple
- Intermittent pain
- Pain present during + immediately after feeding
- Blanching of nipple followed by cyanosis +/or erythema
- Nipple pain resolves when nipples return to normal colour
Management of Raynaud’s disease of the nipple
- Minimise exposure to the cold
- Use of heat packs following breastfeed
- Avoid caffeine
- Stop smoking
if symptoms persist
- refer to a specialist
- oral nifedipine
What is the cut-off weight loss for newborns in the first week of life?
10%
What might loss of more than the cut-off weight in newborns in the first week of life inidcate ?
Losing >10% of birth weight in the first week of life - consider referral to a midwife led breastfeeding clinic
-Should prompt consideration of breast feeding problems:
Poor latching Blocked duct Nipple candidiasis Mastitis Breast abscess Engorgement Raynaud's disease of the nipple
- Examine the infant to look for underlying problems
- Expert review of feeding (midwife-led breastfeeding clinics)
- Monitor wright until weight gain is satisfactory
Breastfeeding contra-indications (not drug-related)
- Galactosaemia*
- Viral infections
*Galactosaemia is an inherited metabolic disease caused by defects in galactose metabolism
Symptoms in babies start to show up within a few days after they begin to drink breast milk or formula with lactose – the milk sugar that contains galactose. They lose their appetite and starts vomiting.
Breastfeeding contra-indications (drug-related)
o Antibiotics: ciprofloxacin, tetracycline, chloramphenicol, sulphonamides o psychiatric drugs: lithium, benzodiazepines o HTN – ARBs, ACEi, amlodipine, statins o aspirin o carbimazole o methotrexate o sulfonylureas o cytotoxic drugs o amiodarone
Drugs allowed in women who are breastfeeding
o Antibiotics o Endocrine o Epilepsy o Asthma o Psychiatric drugs o Hypertension o Anticoagulants
The following drugs can be given to mothers who are breastfeeding:
o Antibiotics: penicillins, cephalosporins, trimethoprim
o Endocrine: glucocorticoids (avoid high doses), levothyroxine*
o Epilepsy: sodium valproate, carbamazepine
o Asthma: salbutamol, theophyllines
o Psychiatric drugs: tricyclic antidepressants, antipsychotics**
o Hypertension: beta-blockers, hydralazine
o Anticoagulants: warfarin, heparin
o Digoxin
*the BNF advises that the amount is too small to affect neonatal hypothyroidism screening
**clozapine should be avoided
Abdominal pain in early pregnancy causes
Ectopic pregnancy RF Damage to tubes (salpingitis, surgery) Previous ectopic IVF (3% of pregnancies are ectopic)
Typical hx: female with a hx of 6-8 weeks amenorrhoea who presents with lower abdominal pain + later develops vaginal bleeding
pain first symptoms constant unilateral due to tubal spasm
vaginal bleeding
less than a normal period
may be dark brown in colour
hx of recent amenorrhoea
typically 6-8 weeks from start of LMP
If longer (e.g. 10 weeks) - this suggests another cause e.g. inevitable abortion
peritoneal bleeding - shoulder tip pain + pain on defecation/urination
Miscarriage
Threatened
- painless vaginal bleeding <24 weeks, typically at 6-9 weeks
- cervical os is closed
- complicates up to 25% of all pregnanies
Missed/delayed miscarriage
- gestational sac with dead fetus before 20 weeks without the symptoms of expulsion
- light vaginal bleeding/discharge
- symptoms of pregnancy disappear
- if gestational sac >25mm + no embryonic/fetal part can be seen - described as “blighted ovum” or “anembryonic pregnancy”
Inevitable miscarriage
- Cervical os is open
- Heavy bleeding with clots and pain
Incomplete miscarriage
- not all products of conception have been expelled
Abdominal pain in late pregnancy causes
Labour
- regular tightening of the abdomen
- may be painful in later sages
Placental abruption
- separation of a normally sited placenta from the uterine wall
- maternal haemorrhage into the intervening space
- occurs in 1/200 pregnancies
- shock out of keeping with visible loss
- constant pain
- tense, tender, “woody” uterus
- normal lie + presentation
- fetal heart - absent/distressed
- coagulation problems
- beware pre-eclampsia, DIC, anuria
Symphysis pubis dysfunction
- Ligament laxity increases in response to hormonal changes of pregnancy
- pain over the pubic symphysis with radiation to the groins + the medial aspects of the thighs
- waddling gait
Pre-eclampsia/HELLP syndrome
- Associated with hypertension/proteinuria
- HELLP - haemolysis, elevated liver enzymes, low platelet count
- pain is typically epigastric or in the RUQ
Uterine rupture - Ruptures usually occur during labour but can also occur in the third trimester - RF Previous C-section - Maternal shock - Abdominal pain - Vaginal bleeding to varying degree
Abdominal pain at any point in pregnancy causes
Appendicitis
- Location of pain changes depending on gestation, moving up from the RLQ in the first trimester to the umbilicus in the second to the RUQ in the third
UTI
- Associated with an increased risk of pre-term delivery + IUGR
What is alpha-fetoprotein (AFP) and what does it mean if it’s increased vs decreased?
AFP is a protein produced by the developing fetus
Increased AFP
- Neural tube defects (meningocele, myelomeningocele, anencephaly)
- Abdominal wall defects (omphalocele, gastroschisis)
- Multiple pregnancy
Decreased AFP
- Down’s syndrome
- Trisomy 18 (Edward’s syndrome)
- Maternal DM

When fetal cells/amniotic fluid enters the mother’s bloodstream and stimulates a reaction which results into
Chills, Shivering, Sweating, Anxiety, Coughing
Cyanosis, hypotension, bronchospasms, tachycardia, arrhythmia, MI
Diagnosis - clinical diagnosis of exclusion
Management -
critical care unit by a multidisciplinary team
Management is predominantly supportive
