Clinical detail

Additional detail checked 2026-10-17 against the linked sources. This check covers the section below; the rest of the module retains its displayed verification status.

Established preterm labour requires simultaneous maternal assessment, fetal assessment and planning for appropriate neonatal care.

Assessment & interpretation

  • Establish gestation, cervical change, membrane status and signs of infection, bleeding or fetal compromise.

Decisions that change management

  • Consider corticosteroids, tocolysis and magnesium for neuroprotection using their distinct eligibility criteria; they are not a single automatic treatment bundle.
  • The aim of tocolysis may include time for corticosteroids and transfer. Contraindications and the safety of delaying birth remain central.

Follow-up & safety-netting

  • Discuss neonatal care and arrange in-utero transfer when clinically appropriate and safe. Record the plan if labour progresses despite treatment.

Admission & discharge

Care setting: Inpatient maternity/neonatal pathway

Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.

When admission or continued hospital care is needed

  • Admit labour with cervical change or a high likelihood of imminent preterm birth; arrange appropriate steroids, neuroprotection, antibiotics/tocolysis when indicated and neonatal discussion.

When clinic, day care or home care may be suitable

  • Established preterm labour is not a routine outpatient discharge diagnosis; transfer decisions depend on gestation, progression and neonatal capacity.

Before going home

  • If labour settles, discharge is a senior obstetric decision after reassessing cervical/membrane status, maternal/fetal wellbeing and access to return care.
  • After preterm birth, assess maternal recovery separately and arrange the baby’s neonatal care; an ongoing neonatal admission needs a clear maternal support/accommodation plan.

Discharge medicines and treatment changes

  • Reconcile what antenatal treatment was completed and any remaining doses; do not continue magnesium infusion or acute tocolysis as home treatment.

Tests, pending results and their reviewer

  • Communicate gestation, membranes, infection assessment and fetal/neonatal findings.

Home care and counselling

  • Give a return/birth plan and discuss feeding, expressing milk and support if the baby needs neonatal admission.

Follow-up: when and what to review

WhenAction / responsible service
Before leaving after settled labour
Write the next review/treatment appointment and the receiving unit if symptoms recur.
After birth
Follow maternal postnatal contacts and the neonatal team’s separate follow-up schedule.

Return urgently

  • Recurrent contractions, fluid loss, bleeding, fever, worsening pain or reduced movements requires immediate reassessment.

Treatment

① Immediate stabilization — first minutes
  • Admit; continuous monitoring; IV access
③ First-line treatment & drug regimens
Betamethasone — antenatal courseWHOsummary checked
Dose12 mg IM, then 12 mg IM 24 hours later
RouteIM
FrequencyTwo doses, 24 h apart
DurationOne 24 mg course. Consider only ONE repeat course under NICE criteria; not routine weekly courses
PreparationConfirm product strength: for 6 mg/mL, 12 mg = 2 mL; volumes differ by formulation. Use the obstetric IM preparation
Max dose24 mg/course; NICE permits no more than 2 courses in total under its repeat-course criteria
  • Imminent preterm birth within the guideline gestational window; do not delay urgent maternal/fetal delivery
  • NICE offers at 24+0–33+6 weeks, considers 34+0–35+6; individual discussion at 22+0–23+6. Repeat: <34 weeks, prior course >7 days ago and very high risk of birth in 48 h.
Monitoring
  • Glucose monitoring and an insulin-adjustment plan in diabetes; assess infection and timing of birth
Contraindications: Do not delay lifesaving delivery to complete steroids; do not use a blanket “infection contraindication” without senior assessment
Nifedipine immediate release — tocolysisMSFchecked
Dose10 mg orally; if contractions persist repeat every 15 min up to four loading doses; then 20 mg every 6 h
RouteOral, never sublingual
FrequencyLoading as specified, then every 6 h
DurationMaximum 48 hours
Preparation10 mg immediate-release tablet/capsule; check BP before dosing and confirm the formulation
Max dose40 mg loading; maintenance 80 mg/day; stop after 48 h
  • Selected threatened preterm labour to gain time for steroids/transfer, without infection, major bleeding or a reason for immediate birth
Monitoring
  • BP/pulse, contraction frequency and fetal heart rate; stop for hypotension or ischaemic chest pain
Contraindications: Systolic BP <90 mmHg, severe cardiac disease · MSF advises against concurrent magnesium; if magnesium is needed, use the agreed obstetric/anaesthetic protocol and do not combine regimens casually
Magnesium sulfate — fetal neuroprotectionNICE · NG25checked
Dose4 g over 15 min, then 1 g/hour
RouteIV infusion
FrequencyLoading once, then continuous infusion
DurationStop at birth or 24 hours, whichever occurs first
Preparation50%: 4 g = 8 mL diluted in compatible sodium chloride 0.9%; maintenance example 20 g made up to FINAL 100 mL, 5 mL/hour via pump
Max dose24 hours for neuroprotection; do not add to an eclampsia regimen already running
  • Imminent preterm birth: NICE offers at 24+0–29+6 weeks and considers at 30+0–33+6 weeks; discuss 23+0–23+6 individually
Monitoring
  • Record pulse, BP, respiratory rate and tendon reflexes at least every 4 h; more often if oliguria or renal impairment
Contraindications: Myasthenia gravis, heart block or magnesium toxicity · Renal impairment or oliguria requires reduced/withheld maintenance and more frequent assessment
  • Atosiban where available/costed; no other tocolytic superior for the 48-h window goal
④ Drug treatment detail (1 agents)
Dexamethasone — antenatal alternativeWHOsummary checked
Dose6 mg IM every 12 h for four doses
RouteIM
FrequencyEvery 12 hours, four doses
Duration24 mg total over 36 h; ONE course, subject to the same repeat-course restrictions
PreparationCheck the injectable product: if 4 mg/mL, 6 mg = 1.5 mL; other strengths require recalculation. Give IM for this antenatal regimen
Max doseFour 6 mg doses = 24 mg/course; do not combine with a full betamethasone course
  • Indication: Alternative fetal-lung-maturation course when appropriate
Monitoring
  • Maternal glucose, infection assessment and birth timing; diabetes team plan
Contraindications: Do not prolong an unsafe pregnancy to finish the course
Non-drug treatment
  • IN-UTERO TRANSFER priority to NICU-equipped centre while tocolysis window open
  • Birth position/mode planned early (breech -> caesarean usual for very preterm)
Definitive treatment
  • Birth (vaginal usually appropriate cephalic; continuous CTG; avoid routine episiotomy; paediatric team present)
  • Delayed cord clamping 30-60 s standard for preterm (unless compromise/intervals conflicting)
Monitoring

Response assessment
  • Contractions controlled through steroid completion + transfer achieved
Treatment failure
  • Labour progressing despite tocolysis -> stop agents, prepare birth; chorioamnionitis -> antibiotics + expedite
Second-line treatment
  • No repeat tocolysis courses beyond window goals
Rescue treatment

Shoulder dystocia/breech entrapment readiness at very-preterm births; theatre standby for selected cases.

Procedure / surgery

Mode decisions individualised: breech <32 wks commonly caesarean in Indian practice; cephalic vaginal birth supported.

Escalation
  • Transfer criteria above
  • HDU if PET overlap/sepsis
⑮ Complications & their management
Chorioamnionitis

Ampicillin+gentamicin(+metronidazole) NOW + birth regardless of gestation

Breech entrapment

Delivery-emergency protocols

Neonatal prematurity complications

Paediatric-led; surfactant availability checked at receiving centre

Post-treatment care
  • Post-birth debrief + documentation of interventions given
  • Next-pregnancy prevention plan: progesterone/cerclage indications reviewed

Diagnosis & assessment

Red flags:
  • Abnormal CTG -> abandon delay strategies
  • Chorioamnionitis signs -> antibiotics + BIRTH (no tocolysis)
  • Breech/transverse complicating mode
  • Multiple pregnancy planning differences

Definition: Regular uterine contractions causing progressive cervical dilatation/effacement before 37+0 weeks.

Initial assessment

  1. Confirm gestation accuracy (dating scans!)
  2. CTG continuous; maternal vitals; urinalysis; infection screen
  3. Presentation confirmed by US
  4. Neonatology consult for counselling at viability margins (24-28 wks India-context individualisation)
  5. Decide: expectant-with-interventions vs active birth pathway

Investigations

TestLooking for
CBC, CRP, urine culture
Occult infection
GBS screening status
Prophylaxis need

Principles & follow-up

Management principles

Guideline conflict

MSF nifedipine tocolysis monograph
Advises against combining nifedipine with magnesium sulfate because of hypotension/neuromuscular-blockade concerns.

India NHM CEmONC 2024, chapter 4
States the feared interaction has not been demonstrated in retrospective reviews, while requiring careful BP and pulse monitoring.

Population/setting difference: MSF addresses nifedipine tocolysis; NHM discusses emergency hypertension/eclampsia care. Dose, indication and monitoring setting differ.

Practical India consideration: Magnesium for indicated seizure prevention or fetal neuroprotection has its own priority; do not withhold it merely to continue tocolysis.

App default: Avoid routine concurrent tocolytic nifedipine and magnesium in this reference. If both are clinically required, a senior obstetric/anaesthetic decision must define monitoring and doses.
Reason: This preserves the source-specific caution and does not turn a monitored emergency-use discussion into blanket permission for coadministration.
