Maternal Sepsis

IN REVIEWv3🇮🇳 India-firstPENDING CLINICAL VERIFICATION⚡ Maternal Sepsis

Pregnancy-specific triggers (septic abortion, chorioamnionitis, endometritis, mastitis necrosis, UTI/pyelo). Sepsis Six adapted: cultures+lactate, broad antibiotics within 1 h, fluids, oxygen as needed, source control (EVACUATE retained products!), hourly reassessment.

Reviewer note: Medication regimens and dependent emergency instructions checked 17 October 2026. These targeted checks do not certify every statement in the module. Admission/discharge guidance checked 18 October 2026. This adds a scoped clinical synthesis and does not certify every statement in the module.

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.

Maternal sepsis assessment must recognise physiological changes of pregnancy and the possibility of rapid deterioration. Source assessment, antimicrobial treatment, haemodynamic care and escalation should proceed together.

Assessment & interpretation

Use the pregnancy-specific risk-assessment pathway and review observations, mental state, oxygenation, urine output and lactate.
Obtain appropriate blood and microbiological samples before antimicrobials when this does not delay urgent treatment. Look for an obstetric, urinary, respiratory, wound or other source.

Decisions that change management

NICE’s high-risk pregnancy pathway requires immediate senior assessment and broad-spectrum antimicrobial treatment within 1 hour of identifying high-risk criteria.
Assess fluid response and the need for critical-care support; persistent circulatory or respiratory compromise needs prompt escalation.
Source control may require obstetric or surgical intervention as well as antibiotics.

Follow-up & safety-netting

Record repeated observations, treatment response and the next reassessment time. A non-response requires a new management decision.
Coordinate obstetric, critical-care and neonatal involvement as appropriate, and communicate the infection and treatment plan at handover.

Clinical pitfalls

An isolated lactate value does not replace the full assessment. Do not apply a general-adult scoring pathway without checking its suitability in pregnancy and the recent postnatal period.

Admission & discharge

Care setting: Emergency hospital admission; organ dysfunction may require critical care

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 suspected sepsis, hypotension, respiratory compromise, altered mental state, oliguria or inability to maintain intake. Arrange urgent source control and appropriate organ support.

When clinic, day care or home care may be suitable

Suspected maternal sepsis with systemic illness is not a routine outpatient antibiotic prescription. A localised infection without sepsis may follow its own outpatient pathway after assessment.

Before going home

The source has been controlled or has a definitive plan; haemodynamics/respiratory function and organ trends support care outside hospital.
No unresolved vasopressor/acute organ-support need; an effective oral regimen or a formally supported outpatient IV service is arranged if antibiotics remain necessary. Persistent fever or deterioration needs reassessment.

Discharge medicines and treatment changes

Reconcile cultures with the actual infection diagnosis; give the selected antibiotic’s dose, route, remaining duration and stop/review date. Do not prescribe every sepsis example combination together.

Tests, pending results and their reviewer

Assign a named reviewer and action plan for pending cultures, susceptibilities, pathology and abnormal renal/liver/blood results; ensure a patient callback route.

Home care and counselling

Explain the source, treatment, risk of recurrence and post-sepsis physical/emotional effects. Provide written warning symptoms, 24-hour access and support for infant care if relevant.

Follow-up: when and what to review

When	Action / responsible service
Before discharge	Book the early clinical/antimicrobial review required by the source and organ injury, with the responsible team.
At the documented postnatal/post-sepsis review	Review recovery, medicines, outstanding results and any specialist rehabilitation needs.

Return urgently

Recurrent fever/rigors, confusion, faintness, breathlessness, reduced urine, worsening abdominal/wound pain or offensive lochia requires immediate reassessment.

Treatment

① Immediate stabilization — first minutes

Measure lactate, obtain appropriate cultures and bloods BEFORE antibiotics only if doing so causes no substantial delay. Give empiric broad-spectrum IV antibiotics ideally within 1 h for septic shock/high-likelihood sepsis.
Select treatment for the suspected source, allergies, renal function and local resistance. The complete cards below show named obstetric-infection combinations, not a claim that one antibiotic treats every maternal sepsis source: chorioamnionitis uses ampicillin PLUS gentamicin; postpartum endometritis may use clindamycin PLUS gentamicin; septic miscarriage needs broad anaerobic cover and evacuation.
For hypotension/hypoperfusion, give balanced crystalloid with frequent response/tolerance checks. SMFM recommends 1–2 L in the first 3 h; NICE NG255 uses 500 mL boluses over <15 min with reassessment and consultant review if two boluses fail. Do not apply an automatic unmonitored 30 mL/kg prescription in pregnancy.
If shock persists or fluids are poorly tolerated, start norepinephrine with critical-care supervision, using the explicit salt/concentration/pump calculation below. Catheterise and track hourly urine output; assess oxygenation and perfusion continuously.

② Assessment & investigations

Never delay antibiotics >45-60 min for results.

③ First-line treatment & drug regimens

Use the indication-specific antimicrobial and vasopressor cards below with the source-control assessment. Regimens are labelled by source and syndrome; do not use one combination for every sepsis presentation.

④ Drug treatment detail (5 agents)

Ampicillin — chorioamnionitis componentMinistry of Health Malaysiachecked

Dose2 g

RouteIV infusion

FrequencyEvery 6 hours

DurationContinue through birth with postpartum review; the cited Malaysian NAG continues until afebrile/asymptomatic ≥48 h. Other national protocols shorten postpartum treatment after clinical recovery

PreparationReconstitute the actual vial per label; dilute each adult dose in 100 mL sodium chloride 0.9% or glucose 5% and infuse over 30 min. Use a separate line/flush from gentamicin

Max dose8 g/day in this 2 g every-6-h regimen; renal impairment requires adjustment

Indication: Intra-amniotic infection, in combination with gentamicin; add anaerobic cover for caesarean according to the chosen guideline
This is not GBS prophylaxis and is not ampicillin monotherapy. The postpartum duration differs between guidelines; record the local choice explicitly.

Monitoring

Temperature, pulse, BP, uterine tenderness, fetal heart rate, cultures and renal function

Contraindications: Penicillin anaphylaxis; check severe delayed beta-lactam reactions

Gentamicin — obstetric infection componentMSFchecked

Dose5 mg/kg using the approved aminoglycoside dosing weight

RouteIV infusion

FrequencyEvery 24 h initially if renal function allows; subsequent interval depends on drug levels and renal function

DurationDaily review; limit unnecessary exposure, stop or narrow after source control and clinical recovery. Duration follows the infection, not a universal 48–72 h rule

Preparation40 mg/mL stock: volume in mL = prescribed mg ÷40. Dilute the adult dose in 100 mL sodium chloride 0.9%/glucose 5%; infuse over 30 min. Use a separate line/flush from beta-lactams

Max doseWeight-based; do not apply total body weight uncritically in obesity. Withhold/review further doses for accumulating levels or renal deterioration

Indication: Combination therapy for chorioamnionitis, postpartum endometritis or septic miscarriage
Renal / hepatic: Adjust interval/dose to renal function and measured levels; do not keep automatic daily dosing in AKI

Monitoring

Baseline and serial creatinine/urine output; drug-level monitoring using the hospital once-daily schedule
Ask about tinnitus, hearing change or vertigo; stop and review suspected ototoxicity

Contraindications: Aminoglycoside allergy; myasthenia gravis, AKI, prior auditory/vestibular toxicity require specialist assessment

Metronidazole — obstetric anaerobic coverMSFchecked

Dose500 mg

RouteIV infusion

FrequencyEvery 8 hours

DurationReview daily and switch to oral when feasible; duration is source-specific: uncomplicated infection recovery versus septic miscarriage (10–14 days in Malaysian NAG)

PreparationReady-to-use 500 mg/100 mL (5 mg/mL) bag infused over 30 min; do not add other drugs to the bag

Max dose1.5 g/day in this regimen; severe hepatic impairment requires reduction

Indication: Combination treatment of selected septic miscarriage/endometritis or caesarean chorioamnionitis
Renal / hepatic: In severe hepatic impairment the cited MSF monograph reduces the daily dose to one third

Monitoring

Clinical response, LFTs in prolonged treatment, interacting anticoagulants and neuropathy with prolonged exposure

Contraindications: Nitroimidazole allergy; severe hepatic impairment requires a reduced regimen

Clindamycin — endometritis componentMinistry of Health Malaysiachecked

Dose900 mg

RouteIV infusion

FrequencyEvery 8 hours

DurationContinue until clinical improvement and afebrile for 24–48 h in the cited NAG regimen; persistent fever needs source reassessment

Preparation150 mg/mL concentrate: 900 mg =6 mL; dilute in compatible IV fluid and infuse over at least 30 min (not IV push)

Max dose2700 mg/day in this regimen

Indication: Postpartum endometritis, in combination with gentamicin when appropriate

Monitoring

Temperature, uterine tenderness, renal function/gentamicin levels for the partner drug; diarrhoea/C. difficile risk

Contraindications: Clindamycin allergy; previous severe antibiotic-associated colitis requires assessment

Norepinephrine (noradrenaline) — MSF peripheral protocolMSFchecked

DoseStart 0.1 microgram/kg/min of NOREPINEPHRINE TARTRATE; increase by 0.05 microgram/kg/min as required

RouteIV infusion pump through a suitable monitored large vein

FrequencyContinuous infusion; MSF reassessment/titration every 10 min initially

DurationUntil perfusion and BP recover; taper gradually, do not stop abruptly

PreparationFor the cited stock 8 mg TARTRATE/4 mL (=4 mg BASE/4 mL): 2 mL contains 4 mg tartrate. Add 38 mL compatible fluid for FINAL 40 mL =100 micrograms TARTRATE/mL. Rate = dose × kg ×60 ÷100 mL/h; at 70 kg and 0.1, rate=4.2 mL/h

Max doseMSF peripheral protocol ceiling 1 microgram/kg/min TARTRATE; persistent/escalating shock requires ICU and central/arterial access planning

Indication: Persistent shock while fluid responsiveness/source control are addressed; first-line vasopressor in maternal septic shock

Monitoring

Continuous ECG, frequent BP (arterial when possible), perfusion and urine output; inspect peripheral site frequently for extravasation
Clearly label SALT versus BASE: this MSF tartrate dose is twice the numerical BASE dose; NEVER copy its pump rate into a base-labelled concentration

Contraindications: Correct hypovolaemia in parallel; vasopressors do not replace haemorrhage control/blood replacement · Extravasation threatens tissue; use a dedicated monitored line, not an unobserved small distal cannula

Definitive treatment

Rapidly remove/control the source: evacuate infected retained tissue, drain an abscess, debride an infected wound or relieve urinary obstruction when indicated.
If the uterus is the suspected/confirmed source, prompt delivery/evacuation may be needed regardless of gestation (SMFM); sepsis alone from another source is not an automatic indication for delivery.
Review antibiotics when microbiology and the clinical response are available, usually within 24–48 h: narrow, adjust renal dosing, stop unnecessary partners and record the total course for the actual infection. Persistent fever/shock requires a search for uncontrolled source or resistant organisms.

Monitoring

Parameter	Frequency until improving
Obs/qSOFA elements	Hourly
Urine output	Hourly (>0.5 mL/kg/h)
Lactate repeat	At 2-4 h if initially raised
Antibiotic review	48-72 h culture-guided de-escalation

Response assessment

Lactate falling, vasopressor-free stability, afebrile trajectory, organ recovery

Treatment failure

Persistent hypotension, escalating vasopressor need, respiratory failure, altered consciousness, rising lactate or organ dysfunction: ICU immediately.

Assess need for ventilation, renal support and obstetric surgery without waiting for a complete test panel.

Second-line treatment

Meropenem-class escalation per microbiology; antifungal consideration prolonged ICU

Rescue treatment

Necrotising infection: emergency wide debridement theatre; toxic-shock physiology: clindamycin+immunoglobulin discussion.

Procedure / surgery

MVA/EVAC under antibiotics COVER (not after "cure") when products retained.

Escalation

HDU/ICU criteria: vasopressors, ventilation, dialysis
Peripheral centre: start bundle THEN transfer with escort
