Obstetrics: Post Natal Care
👶 Labour, birth and the postnatal period — most labours are normal and need support rather than intervention. The skills are recognising normal progress, spotting delay, reading a CTG, knowing when an assisted birth is needed, and caring well for women and babies afterwards. The year after birth is a time of high risk for mental illness: suicide is a leading cause of maternal death in the UK in the year after birth.
Your four questions for every patient: Is labour progressing normally (dilatation, descent, contractions)? Is the baby well (heart rate pattern)? Is the mother well (observations, bleeding, pain, mood)? What does she want — and has her consent been sought for each step?
Stages of Labour
| Stage | What happens |
| First stage — latent phase | Irregular, painful contractions; the cervix softens, shortens (effaces) and dilates up to 4 cm. Can last hours to days, especially in a first labour. |
| First stage — established (active) phase | Regular painful contractions and progressive dilatation from 4 cm to full dilatation (10 cm). Average about 8 hours (first labour, rarely over 18 hours) and 5 hours (later labours, rarely over 12 hours). |
| Second stage | From full dilatation to birth of the baby. Passive (descent without pushing) then active (pushing). Birth is expected within about 3 hours of the start of active second stage in a first labour, and 2 hours in later labours. |
| Third stage | From birth of the baby to delivery of the placenta and membranes. |
- Signs of labour — regular painful contractions, a "show" (mucus plug), rupture of membranes (waters breaking).
- The three Ps that determine progress:
- Power — contractions (frequency, strength, duration; ideally 3–4 in 10 minutes).
- Passenger — the baby's size, presentation, position and attitude (flexion).
- Passage — the pelvis and soft tissues.

How the Baby Is Born
- Terms:
- Lie — the long axis of the baby relative to the mother (longitudinal, transverse, oblique).
- Presentation — the part entering the pelvis first (cephalic, breech, shoulder).
- Position — the position of the denominator (occiput in a cephalic baby) relative to the pelvis — e.g. occipito-anterior (OA) is ideal; occipito-posterior (OP) or transverse (OT).
- Station — level of the head relative to the ischial spines (−3 to +3); or fifths palpable abdominally (engaged when 2/5 or less is palpable).
- Attitude — flexion of the head (a well-flexed head presents the smallest diameter).
- Mechanism of labour (cardinal movements of a cephalic baby):
- Engagement (head enters the pelvis, usually occipito-transverse).
- Descent and flexion.
- Internal rotation to occipito-anterior.
- Extension — the head is born.
- Restitution and external rotation — the head turns to line up with the shoulders.
- Delivery of the shoulders (anterior first) and body.

Care in Normal Labour
- Place of birth (NICE) — women with uncomplicated pregnancies can choose:
- Home, a freestanding or alongside midwifery unit, or an obstetric unit.
- For women who have had a baby before, midwife-led settings are as safe for the baby and have fewer interventions.
- For a first baby, a home birth has a small increase in adverse outcomes for the baby.
- Supportive care:
- One-to-one midwifery care in established labour.
- Encourage movement and upright positions; eat and drink lightly; empty the bladder regularly.
- Water immersion for pain relief.
- Monitoring the mother — pulse hourly, BP and temperature 4-hourly, contractions every 30 minutes, vaginal examination about 4-hourly (or if concerns), fluid balance. Recorded on a partogram.
- Monitoring the baby — intermittent auscultation for low-risk labours; continuous CTG for higher risk (see below).
- Signs that need obstetric review:
- Maternal fever (38 °C or more), tachycardia, raised BP.
- Meconium-stained fluid (significant).
- Fresh bleeding.
- Abnormal fetal heart rate.
- Delay in progress.
- Malpresentation, cord presentation.
- Prelabour rupture of membranes at term — see the Obstetric Complications chapter.
↑ Back to index
Delay in Labour
- Delay in the first stage (NICE) — suspected if:
- Cervical dilatation of under 2 cm in 4 hours (first or later labours).
- Slowing progress in a later labour.
- Changes in descent or rotation, or in the strength, duration and frequency of contractions.
- Actions:
- Amniotomy (if membranes intact) — reassess in 2 hours.
- Oxytocin infusion (augmentation) if progress remains slow — with continuous CTG; reassess after 4 hours.
- Caesarean if progress doesn't improve (or fetal concerns).
- Check for obstruction — high head, moulding, caput, cervix not applied to the head (oxytocin is dangerous in obstruction, especially in women who have given birth before — rupture risk).
- Delay in the second stage:
- First labour — suspected after 1 hour of active pushing; diagnosed if birth isn't imminent after 2 hours (refer at that point).
- Later labours — suspected after 30 minutes; diagnosed after 1 hour.
- Actions — obstetric review; consider oxytocin (first labour with poor contractions), position change; instrumental birth or caesarean.
- Causes — inefficient contractions (the commonest in a first labour), malposition (OP), deflexion, large baby, small pelvis (cephalopelvic disproportion), full bladder, exhaustion.

Fetal Monitoring and the CTG
- Intermittent auscultation (low-risk labour) — listen with a Pinard or handheld Doppler for 1 minute after a contraction: every 15 minutes in the established first stage, every 5 minutes in the second stage; feel the maternal pulse to distinguish.
- Continuous CTG (cardiotocography) is recommended for:
- Maternal factors — pre-eclampsia, diabetes, previous caesarean, fever, sepsis, APH, oxytocin, epidural (for 30 minutes after placement or top-ups), prolonged labour.
- Fetal factors — FGR, preterm, breech, twins, meconium, reduced movements, abnormal auscultation.
- Reading a CTG (one way to remember — "Dr C BRAVADO": Define Risk, Contractions, Baseline RAte, Variability, Accelerations, Decelerations, Overall):
| Feature | Normal and abnormal |
| Baseline rate | Normal 110–160 beats/min. Tachycardia — fever, infection, maternal tachycardia, hypoxia, drugs. Bradycardia under 100 for over 3 minutes — acute emergency. |
| Variability | Normal 5–25 beats/min. Reduced (under 5) for over 30–50 minutes is a concern (hypoxia, sleep, drugs like opioids). Increased (over 25) — "saltatory". |
| Accelerations | Rises of 15 beats/min for 15 seconds — reassuring. Their absence alone is not worrying. |
| Early decelerations | Mirror contractions (head compression) — usually benign. |
| Variable decelerations | Vary in shape and timing; cord compression. Concerning if lasting over 60 seconds, with reduced variability, or slow recovery. |
| Late decelerations | Start after the peak of a contraction and recover after it ends — placental insufficiency (hypoxia). Concerning. |
| Prolonged deceleration | Over 3 minutes — urgent action; over 5 minutes, deliver if not recovering (by 9 minutes). |
| Sinusoidal pattern | Smooth wave-like — severe fetal anaemia (vasa praevia, fetomaternal haemorrhage) — urgent. |
- Overall assessment (NICE NG229) — consider the whole clinical picture (risk factors, progress, trends over time), not the CTG in isolation.
- Actions for concerning features:
- Correct reversible causes — change position (left lateral), stop or reduce oxytocin, treat low BP (fluids after epidural), treat fever, tocolysis for hyperstimulation.
- Senior review; consider expediting birth.
- Fetal blood sampling (scalp lactate or pH) is now used less often.
- Fetal scalp electrode if the external trace is poor.

Pain Relief in Labour
- Non-drug — support, breathing, massage, movement, water (birth pool); TENS in early labour.
- Entonox (50% nitrous oxide and oxygen) — fast-acting; light-headedness, nausea.
- Opioids — IM pethidine or diamorphine: nausea and drowsiness; can cause breathing depression in the baby if given within a few hours of birth (naloxone for the baby); may reduce breastfeeding. Remifentanil patient-controlled analgesia (with one-to-one monitoring) if epidural isn't possible.
- Epidural — the most effective:
- Low-dose local anaesthetic plus opioid into the epidural space.
- Effects — longer second stage, more instrumental births (not more caesareans); low BP; itching; fever; urinary retention (catheter); leg weakness.
- Complications — post-dural puncture headache (worse sitting up — epidural blood patch); rare high block, nerve damage, epidural haematoma or abscess.
- Contraindications — patient refusal, coagulopathy or low platelets (e.g. under 75–80 × 10⁹/L), LMWH within 12 hours (prophylactic) or 24 hours (treatment dose), local infection, uncorrected hypovolaemia.
- Spinal anaesthetic — for caesarean and instrumental births in theatre (single injection, rapid, dense block).
- General anaesthesia — category 1 caesarean when regional isn't possible; risks of difficult airway and aspiration (antacid prophylaxis).
↑ Back to index
Malposition and Malpresentation in Labour
- Occipito-posterior (OP) — the commonest malposition:
- Back pain, slow labour, early urge to push.
- Most rotate to OA spontaneously; otherwise rotational instrumental birth (Kielland's forceps or ventouse), manual rotation, or caesarean; or born "face to pubis".
- Deflexed head — larger diameter presents; slow labour.
- Face presentation (fully extended head) — vaginal birth possible if mento-anterior; mento-posterior needs caesarean. Never use ventouse on a face.
- Brow presentation (partly extended) — largest diameter; caesarean unless it flexes.
- Transverse lie in labour — caesarean (risk of cord prolapse and obstructed labour).
- Cord presentation (cord below the presenting part with intact membranes) — caesarean.
- Obstructed labour — no progress despite good contractions; caput and moulding, high head, haematuria; risk of uterine rupture and fistula — caesarean.
↑ Back to index
Instrumental Birth
- Indications:
- Delay in the second stage.
- Suspected fetal compromise.
- Maternal reasons to shorten pushing — exhaustion, heart disease, severe hypertension, some neurological conditions (e.g. intracranial aneurysm), proliferative retinopathy.
- Prerequisites (RCOG):
- Cervix fully dilated; membranes ruptured.
- Head 1/5 or less palpable abdominally (0/5 ideal) and at or below the ischial spines.
- Position known exactly.
- Adequate analgesia; empty bladder; contractions present.
- Informed consent; experienced operator; backup plan (theatre if a higher-risk "trial").
- Ventouse (vacuum cup):
- Less maternal trauma than forceps; more likely to fail.
- Not before 34 weeks (bleeding risk), and not for face presentations.
- Baby — chignon (normal swelling), cephalhaematoma, subgaleal haemorrhage (rare, dangerous — boggy scalp swelling crossing suture lines, shock), jaundice, retinal haemorrhages.
- Forceps:
- More successful; more perineal and anal sphincter tears.
- Baby — facial bruising, facial nerve palsy (usually recovers), skull fracture (rare).
- Rotational forceps (Kielland's) for OP/OT — experienced operators only.
- After instrumental birth — check for OASI; offer prophylactic antibiotics (single dose of co-amoxiclav — ANODE trial); VTE assessment; bladder care (retention after epidural); debrief.
↑ Back to index
Caesarean Birth
- About a third or more of UK births are now caesarean.
- Urgency categories (NICE):
| Category | Meaning and target |
| 1 | Immediate threat to the life of the mother or baby (e.g. prolonged bradycardia, cord prolapse, abruption, uterine rupture) — birth within 30 minutes of the decision |
| 2 | Maternal or fetal compromise that is not immediately life-threatening — within 75 minutes |
| 3 | No compromise but needs early birth (e.g. failed induction, labouring with a planned caesarean booked) |
| 4 | Planned (elective) — at a time to suit the woman and team (usually from 39 weeks to reduce baby breathing problems) |
- Common reasons — previous caesarean, failure to progress, suspected fetal compromise, breech, placenta praevia, maternal request (should be supported after discussion), some maternal conditions (HIV with high viral load, primary herpes near term).
- Before surgery:
- Consent (including risks below); FBC, group and save.
- Antacid prophylaxis (H2 blocker or PPI, plus antiemetic).
- Antibiotics before skin incision (e.g. cefuroxime).
- Steroids for planned caesarean before 39 weeks (consider).
- VTE prophylaxis — stockings, LMWH for most after surgery.
- Usually spinal anaesthetic; low transverse (Pfannenstiel) incision; lower segment uterine incision.
- Risks:
- Mother — bleeding, infection (wound, endometritis), VTE, bladder or bowel injury, longer recovery; future placenta praevia and accreta, uterine rupture.
- Baby — transient tachypnoea (breathing problems, especially before 39 weeks), small skin cuts.
- Recovery — early eating and walking; catheter removal after about 12 hours; avoid heavy lifting; can drive when able to do an emergency stop comfortably; wait at least 12–18 months before another pregnancy.
↑ Back to index
Perineal Tears and Episiotomy
| Degree | What is torn |
| First | Skin of the perineum or vaginal lining only |
| Second | Perineal muscles (not the anal sphincter); episiotomy is the same depth |
| Third | Anal sphincter: 3a — under 50% of external sphincter; 3b — over 50%; 3c — internal sphincter too |
| Fourth | Anal sphincter complex and the anal lining (rectal mucosa) |
- Obstetric anal sphincter injury (OASI) — third and fourth degree tears:
- Risk factors — first vaginal birth, forceps, large baby (over 4 kg), OP position, prolonged second stage, shoulder dystocia, South Asian ethnicity.
- Examine the perineum and rectum after every vaginal birth.
- Repair in theatre by an experienced clinician; IV antibiotics; laxatives; analgesia (avoid codeine — constipation).
- Follow-up — pelvic floor physiotherapy; review at 6–12 weeks (faecal incontinence, pain); future birth plans (endoanal ultrasound and manometry).
- Prevention — hands-on control of the head, warm compresses, mediolateral episiotomy at instrumental birth.
- Episiotomy — a mediolateral cut (at about 60° from the midline when the head is crowning) for instrumental birth or fetal compromise; not routine.
- Other — labial and periurethral tears; vulval haematoma (severe pain, swelling after birth — drain); obstetric fistula (prolonged obstructed labour, low-income countries).
↑ Back to index
The Third Stage and the Newborn
- Active management of the third stage (recommended — halves PPH risk):
- Oxytocin 10 IU IM as the baby's anterior shoulder is born or straight after birth (Syntometrine — oxytocin with ergometrine — can be used if no hypertension).
- Deferred cord clamping — wait at least 1 minute (and up to 5 minutes) if the baby is well.
- Controlled cord traction after signs of separation.
- Placenta usually delivered within 30 minutes.
- Physiological third stage — no drugs, placenta delivered by maternal effort; prolonged if over 1 hour.
- Retained placenta — not delivered within 30 minutes (active) or 1 hour (physiological): IV access, bloods, empty bladder; manual removal in theatre (regional anaesthetic); antibiotics. Heavy bleeding — emergency.
- Check the placenta is complete (missing parts — retained tissue, PPH).
- Newborn care:
- Skin-to-skin contact; dry and keep warm; early breastfeeding.
- Apgar score at 1 and 5 minutes (heart rate, breathing, tone, reflex irritability, colour).
- Vitamin K (IM or oral) to prevent haemorrhagic disease of the newborn — with consent.
- Newborn physical examination within 72 hours (see the Neonatology chapter).
↑ Back to index
Postnatal Care
- Normal changes:
- Lochia — blood loss: red for a few days, then brown and pale; up to about 6 weeks.
- Uterine involution — the womb shrinks back into the pelvis by about 2 weeks; "afterpains" (worse with breastfeeding).
- Breast milk — colostrum first, milk "comes in" at day 2–4.
- "Baby blues" — tearful, emotional days 3–10; settles by 2 weeks.
- Postnatal checks (NICE NG194):
- Midwife visits at home in the first days; health visitor from 10–14 days.
- BP (pre-eclampsia can start after birth), temperature, pulse, bleeding, perineum or wound, bladder and bowels, legs (VTE), breasts, mood, pain.
- Passed urine within 6 hours of birth — if not, bladder scan or catheter (retention).
- 6–8 week GP check — physical and mental health, contraception, cervical screening if due, pelvic floor, BP, diabetes test after GDM.
- Warning signs to tell women about:
- Heavy or sudden increase in bleeding, clots, smelly discharge.
- Fever, rigors, feeling very unwell (sepsis).
- Headache, visual changes, epigastric pain (pre-eclampsia).
- Calf pain or swelling, breathlessness, chest pain (VTE).
- Thoughts of self-harm, feeling very low, unusual or frightening thoughts.
- Other advice — pelvic floor exercises; sex when comfortable; safe sleep for the baby; vitamin D; immunisation (MMR if not rubella immune).
↑ Back to index
Contraception After Birth
- Fertility returns as early as day 21 after birth — contraception is needed from then.
- Lactational amenorrhoea method (LAM) — over 98% effective if all three apply: fully (or nearly fully) breastfeeding, no periods, and baby under 6 months.
- Progestogen-only methods — the pill, implant — can start any time after birth (including straight away); safe with breastfeeding. Injection can also start any time (but may increase heavy bleeding if given early).
- Combined hormonal contraception:
- Breastfeeding — avoid until 6 weeks (UKMEC 4 before 6 weeks).
- Not breastfeeding — avoid before day 21 (VTE risk); from 21 days if no other VTE risk factors (from 6 weeks if risk factors).
- IUD or IUS — within 48 hours of birth (including at caesarean), or from 4 weeks after birth (not in between — higher expulsion and perforation risk).
- Sterilisation — usually not at caesarean (regret higher; less effective than LARC) unless planned well in advance.
- Pregnancy spacing — ideally at least 12–18 months between birth and the next conception.
↑ Back to index
Breastfeeding
- WHO and UK advice — exclusive breastfeeding for around 6 months, then continued alongside solid foods.
- Benefits for the baby — fewer infections (gastroenteritis, chest and ear infections), lower risk of sudden infant death, NEC (preterm babies), obesity and diabetes.
- Benefits for the mother — lower risk of breast and ovarian cancer, type 2 diabetes, cardiovascular disease; helps bonding; free.
- Good attachment — baby's mouth wide open, chin touching the breast, more areola visible above the top lip, cheeks full, rhythmic sucking and swallowing; feeding shouldn't hurt.
- Signs of good feeding — at least 6 wet nappies a day after day 5, yellow stools, weight regained by about 2 weeks (babies can lose up to 10% of birth weight in the first days).
- When not to breastfeed — HIV (unless supported and virally suppressed), some drugs (e.g. cytotoxics, lithium without specialist plan), galactosaemia in the baby, active untreated TB (until treated for 2 weeks).
- Formula feeding — support all feeding choices; teach safe preparation (water at 70 °C or more, sterile bottles); responsive feeding.
- UNICEF Baby Friendly Initiative standards in UK maternity units.
↑ Back to index
Breastfeeding Problems and Mastitis
- Sore, cracked nipples — usually poor attachment; get feeding support; check for tongue-tie (frenotomy if it causes feeding problems).
- Engorgement — full, hard, painful breasts (days 3–5); frequent feeding, hand expression, cold compresses, paracetamol or ibuprofen.
- Blocked duct — tender lump; keep feeding, massage towards the nipple.
- Mastitis — painful, red, hot wedge of breast, with fever and flu-like symptoms:
- Keep breastfeeding (or expressing) from the affected side; analgesia (ibuprofen is fine).
- Antibiotics — flucloxacillin 500 mg four times daily for 10–14 days (erythromycin or clarithromycin if allergic) if symptoms don't improve within 12–24 hours, if there is a cracked nipple that looks infected, or if culture is positive.
- Admit if septic.
- Breast abscess — a tender, fluctuant mass; ultrasound; needle aspiration or drainage plus antibiotics; breastfeeding can usually continue.
- Nipple thrush — burning, shooting pain after feeds, shiny skin; baby has oral thrush: treat both (miconazole for mother's nipples, miconazole or nystatin for the baby).
- Low milk supply — usually from infrequent feeds or poor attachment; feeding support.
- Persistent lump — after treatment, breast cancer can present in pregnancy or breastfeeding: ultrasound.
↑ Back to index
Postnatal Complications
- Secondary PPH — abnormal bleeding from 24 hours to 12 weeks after birth:
- Causes — retained placental tissue and endometritis (infection).
- Management — observations, swabs, FBC, CRP; ultrasound; antibiotics; surgical evacuation if retained tissue and heavy bleeding.
- Endometritis — fever, lower abdominal pain, offensive lochia, tender womb; more common after caesarean; IV or oral antibiotics (e.g. co-amoxiclav, or clindamycin with gentamicin); think group A streptococcus if very unwell.
- Wound infection after caesarean — redness, discharge; swab, antibiotics, check for collection.
- Urinary retention — after epidural or instrumental birth; catheterise (prevents long-term bladder damage).
- Urinary and faecal incontinence — pelvic floor exercises; OASI follow-up.
- VTE — highest risk in the first 6 weeks.
- Postnatal pre-eclampsia — BP checks.
- Headache — post-dural puncture, pre-eclampsia, cerebral venous sinus thrombosis, subarachnoid haemorrhage, migraine — investigate new severe headache.
- Sheehan's syndrome — pituitary infarction after massive PPH: failure to lactate, tiredness, amenorrhoea, low BP and sodium (adrenal insufficiency) — see the Pituitary chapter.
- Postpartum thyroiditis, peripartum cardiomyopathy — see the Medical Problems in Pregnancy chapter.
↑ Back to index
Perinatal Mental Health
- Why it matters: Mental illness affects up to 1 in 5 women in pregnancy and the year after birth. Suicide is a leading cause of maternal death in the UK in the first year after birth (MBRRACE-UK).
- Ask at every contact — mood, anxiety, sleep, past history (especially bipolar disorder or previous puerperal psychosis), family history.
- Baby blues — days 3–10; up to 80% of women; tearful, labile mood; settles within 2 weeks; reassurance and support.
- Postnatal depression:
- About 1 in 10 women; usually within the first few months (can start in pregnancy).
- Low mood, loss of interest, poor sleep (even when baby sleeps), guilt, anxiety about the baby, poor bonding, thoughts of self-harm.
- Screening — Whooley questions; Edinburgh Postnatal Depression Scale (EPDS); GAD-2 for anxiety.
- Treatment — support, guided self-help, CBT or interpersonal therapy; SSRIs (sertraline is often used in breastfeeding).
- Also affects fathers and partners.
- Puerperal (postpartum) psychosis — a psychiatric emergency:
- About 1–2 in 1,000 births; usually within the first 2 weeks (often days 3–7).
- Rapid onset — confusion, agitation, mania, delusions (often about the baby), hallucinations, severe insomnia, rapidly changing mood.
- Highest risk — bipolar disorder (about 1 in 4), previous puerperal psychosis, family history.
- Same-day psychiatric assessment; admission to a mother and baby unit; antipsychotics, mood stabilisers, sometimes ECT; risk assessment for mother and baby; safeguarding.
- Prevention — pre-pregnancy and antenatal plans with the perinatal mental health team for women at high risk.
- Other conditions — perinatal anxiety, OCD (intrusive thoughts of harming the baby — distressing but not acted on), PTSD after traumatic birth (debrief, trauma-focused therapy), tokophobia (fear of birth), eating disorders.
- Red flags for urgent review:
- Recent significant change in mental state or new symptoms.
- New thoughts or acts of violent self-harm.
- New and persistent feelings of being incompetent as a mother or estranged from the baby.
- Medicines in pregnancy and breastfeeding — weigh the risks of untreated illness; avoid valproate; specialist advice for lithium.
⚠️ Safety Pearl: Rapidly changing mood, confusion or strange beliefs in the first weeks after birth — especially with a history of bipolar disorder — is puerperal psychosis until proven otherwise. Arrange same-day psychiatric assessment.

Exam-style Scenarios
1. A 27-year-old in her first labour has been fully dilated and pushing for 2 hours. The head is 0/5 palpable, at +1 station, OA position, with an epidural. CTG shows recurrent variable decelerations.
Answer: Delay in the second stage with suspected fetal compromise.
- Prerequisites met — instrumental birth (ventouse or forceps) with consent, empty bladder.
- Check for OASI afterwards; single-dose co-amoxiclav; bladder care.
2. A woman in established labour on oxytocin has a CTG with baseline 150, variability 3 for 60 minutes, and late decelerations with most contractions.
Answer: Concerning CTG suggesting fetal hypoxia.
- Stop or reduce oxytocin; left lateral position; check maternal BP and temperature.
- Senior obstetric review; expedite birth if no improvement (instrumental if fully dilated, otherwise caesarean).
3. A 31-year-old on day 10 after birth has a painful, red, hot area on the left breast and a temperature of 38.4 °C. She is breastfeeding.
Answer: Mastitis.
- Continue breastfeeding or expressing; analgesia; check attachment.
- Flucloxacillin if not improving within 12–24 hours (or infected cracked nipple).
- Ultrasound if a fluctuant lump (abscess); admit if septic.
4. A woman with bipolar disorder is brought in by her partner on day 6 after birth. She hasn't slept, is talking rapidly and says the baby is not hers.
Answer: Puerperal psychosis.
- Same-day psychiatric assessment; don't leave her alone with the baby; risk assessment.
- Admission to a mother and baby unit; antipsychotic or mood stabiliser.
- Safeguarding; plan for future pregnancies.
5. A 25-year-old, fully breastfeeding, 3 weeks after birth, asks about contraception.
Answer: Postnatal contraception.
- LAM is effective while fully breastfeeding, no periods and baby under 6 months.
- Progestogen-only pill or implant can start now.
- Avoid combined methods until 6 weeks; IUD or IUS from 4 weeks.
↑ Back to index
Key Points
- Established labour starts at 4 cm with regular contractions; delay is under 2 cm in 4 hours.
- Delay in the first stage: amniotomy, then oxytocin with continuous CTG, then caesarean if no progress.
- Second stage: birth expected within about 3 hours (first labour) or 2 hours (later labours) of active pushing.
- CTG: baseline 110–160, variability 5–25; late decelerations and reduced variability are concerning; interpret in context.
- Epidural: most effective; longer second stage and more instrumental births; low BP, fever, PDPH.
- Instrumental birth needs full dilatation, head 1/5 or less palpable, known position, analgesia, empty bladder and consent.
- Caesarean categories: 1 (within 30 min), 2 (within 75 min), 3, 4 (planned from 39 weeks).
- OASI: third and fourth degree tears — repair in theatre, antibiotics, laxatives, physiotherapy.
- Active third stage: oxytocin 10 IU IM, deferred cord clamping, controlled cord traction.
- Fertility returns from day 21; progestogen-only methods any time; no combined methods before 6 weeks if breastfeeding.
- Mastitis: keep breastfeeding; flucloxacillin if not improving.
- Secondary PPH: retained tissue or endometritis — antibiotics ± evacuation.
- Puerperal psychosis is an emergency — same-day psychiatry and mother and baby unit; highest risk with bipolar disorder.
