Post-Partum Period & Complications Flashcards
What is the Edinburgh tool used for?
Detecting/screening for postnatal depression
What percentage of women are affected by “baby-blues”?
60-70%
Who is the baby-blues most commonly seen in?
Primips
What are the baby-blues?
Mood disorder experienced after childbirth, typically characterised by anxiety, tearfulness, and irritability.
Experienced 3-7 days following birth.
How should baby-blues be managed?
With reassurance and support, often the health visitor plays a key role.
What is the next step up in severity from baby-blues?
Post-natal depression
How common is post-natal depression?
Around 10% of women are affected
When does postnatal depression strike?
Within a month after birth, and usually peaks at 3 months.
How does post-natal depression present?
Like normal depression, but in the post-natal period
What are the elements of management for postnatal depression?
- Reassurance and support throughout
- CBT
- SSRIs if severe
Which SSRIs can be used in severe post-natal depression?
Sertraline and paroxetine
Paroxetine is recommended by SIGN as it has a low milk/plasma ratio
What is the next step up from post-natal depression?
Puerperal psychosis
How common is puerperal psychosis?
Approx. 0.2% of women are affected
When does puerperal psychosis start to affect a woman?
Onset within first 2-3 week after birth
How is puerperal psychosis different to postnatal depression?
It is more severe - more severe mood swings similar to bipolar, disordered perception, including auditory hallucinations.
How should puerperal psychosis be managed?
Usually hospital admission is needed.
If a woman suffers from puerperal psychosis, how likely is it she will suffer from it again?
20% risk of recurrence
What is a post-partum haemorrhage?
Excessive bleeding following delivery.
What are primary and secondary postpartum haemorrhage?
Primary is loss of blood over 500ml from genital tract within 24 hours of delivery.
Secondary is from 24 hours after delivery until six weeks postpartum.
What is classified as minor and major PPH?
Minor is up to 1000mls
Major is over 1000mls
What memory aid can we use to rememeber the causes of PPH?
Four Ts: Tone Trauma Tissue Thrombin
What tone issues can cause PPH?
Uterine atony
Distended bladder
What trauma issues can cause PPH?
Lacerations of the uterus, cervix, or vagina
What tissue issues can cause PPH?
Retained placenta or clots
What thrombin issues can cause PPH?
Pre-existing or acquired coagulopathy
What are the 2 most common causes of PPH, and which is the most most common?
- Uterine atony
2. Retained placenta
How common is PPH?
Incidence is roughly 5-10%.
Major PPH incidence is roughly 1%.
What antenatal factors increase the risk of PPH?
- Antepartum haemorrhage
- Placenta praevia or abruption
- Multiple pregnancy
- Pre-eclampsia/HTN
- Grand parity
- Prev. PPH
- Maternal obesity
- Maternal age
- Maternal anaemia
- Asian ethnic origin
What delivery factors increase the risk of PPH?
- Emergency or elective c-section
- Retained placenta
- Induction of labour
- Operative vaginal delivery
- Labour over 12 hours
- Big baby
What pre-existing maternal factors increase the risk of PPH?
Von Willebrand’s disease
Factor 8 or 9 deficiency (Haemophilia A or B carrier)
What signs accompany the blood loss in PPH?
Signs of shock e.g. tachycardia, hypotension, tachypnoea
Which syndrome is associated with PPH?
HELLP syndrome
How should PPH be managed?
ABCDE!!!
IV access with 2 x 14 gauge cannulae.
Blood transfusion asap, with warmed IV fluids (up to 2L) until it is available.
Take measures to stop the bleeding.
How many units of blood should be crossmatched for a major PPH?
At least 4
What measures can be taken to stop bleeding in PPH?
Establish the cause, treat the cause:
-Uterine atony - bimanual compression, empty bladder, Oxytocin 5 units by IV infusion. Repeat as necessary. Ergometrine can be given unless hx of HTN. Carboprost and Misoprostol can also be used. Surgically, balloon tamponade, ligatoin of ateries, or selective arterial embolisation can be used. Hysterectomy is last line option.
What are the complications of PPH?
- Hypovolaemic shock
- DIC
- AKI
- Liver failure
- ARDS
- Death
What is the prognosis like for PPH?
Very good - UK risk for death due to PPH is 1 in 100,000 deliveries.
How can we prevent PPH?
Active thrid stage management - prophylactic oxytocics (IM for vaginal, IV for c-section). Misoprostol is good alternative for low resource area.
What are the 2 most common causes of secondary post partum haemorrhage?
- Infection (endometritis)
2. Retained products of conception
How do secondary PPH present?
Symptoms include:
- Fever
- Abdo pain
- Offensive smelling lochia
- Abnormal PV bleed or discharge
- Dyspareunia
- Dysuria
- General malaise
What hx would indicate higher risk of PPH?
Extended labour
Difficult thrid stage
Ragged placenta
PPH
What does the fundus feel like in RPOC?
It is elevated and feels boggy
How should ?2ndary PPH be investigated?
FBC Blood culture MSU High vaginal swab and chlamydia/gonorrhoea swab USS (for RPOC)
How should secondary PPH be managed?
ABCDE!! Look for red flag sepsis also.
IV/oral abx for endometritis (depending on how unwell pt is).
Elective curettage with abx cover.
Which abx are suggested by the RCOG guidelines for sepsis following pregnancy?
Piperacillin or tazobactim
What is the biggest risk of removing RPOC with curettage?
High risk of uterine perforation.
How common are 3rd/4th degree perineal tears in:
a) primiparous women?
b) multiparous women?
a) 4-7%
b) 1.4-2.5%
Lower for spontaneous vaginal than instrumental delivery.
What are the indications for an episiotomy?
- Delayed delivery due to rigid perineum
- Tear imminent and episiotomy preferable
- In some instrumentals to facilitate delivery
- In some premature deliveries
Should episiotomies be done routinely or restrictively? Why?
Restrictively - lower risk of clinically relevant morbidities.
What is defined as a first degree perineal tear?
Damage to the fourchette and vaginal mucosa, but underlying muscles are not torn (but are exposed).
What is defined as a second degree perineal tear?
Posterior vaginal wall and perineal muscles, but anal sphincter is intact.
What is defined as a third degree perineal tear?
Tear extends to anal sphincter but the rectal mucosa is intact
What is defined as a fourth degree perineal tear?
Anal canal is opened and tear spreads into the rectum
When should an episiotomy be performed?
During the second stage of labour when the perineum is being stretched.
Informed consent is needed, and this can’t be given when the baby is crowning.
What kind of episiotomy is usually recommended?
A mediolateral episiotomy
Why are midline episiotomies not recommended?
They may extend backwards into the rectum to produce a third or fourth degree tear
How should perineal tears be managed?
Ensure adequate analgesia.
Stitches and sutures usually used for 2nd-4th degree tears.
First degree often left to heal by secondary intention.
What can be done to minimise the risk of perineal tear?
- Antenatal perineal massage
- Warm compress during second stage of labour
- Water births
What are the complications associated with perineal trauma?
- Pain
- Infection
- Bleeding
- Extension of original cut/tear
- Problems with micturition and defecation
What does WHO recommend about breastfeeding?
Exclusive breastfeeding for first 6 months of life
Which demographics of mothers are more likely to breast feed?
- Minority ethnic groups
- Managerial/professional occupations
- Over 30
- First time mothers
- Left full time occupation after age 18
What are the social benefits and detractions of breastfeeding?
Benefit - free, no need to buy equipment or formula.
Detractions - socially taboo.

- Immunity/infection protection
- Protection against eczema and asthma
- Reduced rate of SIDS
- Reduced risk of future type 2 diabetes.
What are the medical benefits of breastfeeding for the mother?
Reduced risk of breast and ovarian cancer, diabetes and metabolic syndrome, as well as working as a form of contraception.
What are the medical disadvantages of breastfeeding for the mother?
Vertical transmission of HIV.
Certain medications can be fed to the baby via breast milk
What are the problems associated with breast feeding?
- Cracked/sore nipples
- Blocked ducts
- Mastitis/abscess
- Thrush/ductal candidiasis
- Insufficient milk/frequent feeding - very normal to have to feed frequently, but mothers often lose confidence in their ability to feed the baby.
When should breastfeeding be estabilshed?
Within an hour of birth, and then on demand, as often as the baby needs.
