Here is the complete, structured DNB-level answer on Anesthetic Management of a 25-Year-Old Woman Who Collapsed After Delivery.

Anesthetic Management of Postpartum Collapse

References: Miller's Anesthesia 10e, Creasy & Resnik's Maternal-Fetal Medicine, Knapp & Bhatia (Br J Hosp Med 2022, PMID 36594762), ASA Practice Guidelines for Obstetric Anesthesia, SOAP Consensus Statement on Cardiac Arrest in Pregnancy

STEP 1 - DEFINITION AND SCOPE

Postpartum collapse is a sudden, life-threatening deterioration in a woman's cardiovascular, respiratory, or neurological status occurring after delivery, up to 6 weeks postpartum. It is a multidisciplinary emergency requiring immediate involvement of the obstetric anaesthetist, obstetrician, midwife, and intensivist.

DIAGRAM 1 - Causes of Postpartum Collapse

Causes of Postpartum Collapse

Causes - Mnemonic "HAEMORRHAGE" or ABCDE Framework:

SystemCause
AAmniotic Fluid Embolism (AFE)
BBleeding - PPH (most common)
CCardiac - Peripartum cardiomyopathy, arrhythmia, MI
DDVT/Pulmonary Embolism
EEclampsia / HELLP syndrome
+Septic shock
+Local Anaesthetic Systemic Toxicity (LAST)
+Vasovagal / Spinal hypotension (if recent neuraxial block)
+Uterine inversion
+Anaphylaxis

STEP 2 - IMMEDIATE RESPONSE (First 5 Minutes)

Call for Help - Assemble the Team:

  • Obstetric anaesthetist (lead airway + resuscitation)
  • Obstetrician + Senior midwife
  • Neonatology team
  • ICU/HDU team
  • Blood bank - alert early

DIAGRAM 2 - Anesthetic Management Algorithm

Anesthetic Management Algorithm

STEP 3 - PRIMARY SURVEY (ABCDE)

A - Airway

  • Assess patency; protect if reduced GCS
  • High aspiration risk - postpartum patients have full stomach, delayed gastric emptying, raised intragastric pressure
  • If unconscious or GCS <8: Rapid Sequence Induction (RSI)
    • Preoxygenate 3 min (or 8 vital capacity breaths) with 100% O₂
    • Induction: Ketamine 1-2 mg/kg (preserves haemodynamics) OR Etomidate 0.2-0.3 mg/kg if haemodynamically unstable
    • Avoid propofol if hypotensive
    • Suxamethonium 1.5 mg/kg + cricoid pressure
    • Cuffed ETT; confirm with capnography and bilateral air entry

B - Breathing

  • 100% FiO₂ post-intubation
  • Maintain SpO₂ >95%, ETCO₂ 35-40 mmHg
  • Ventilate with tidal volume 6-8 mL/kg ideal body weight
  • PEEP 5-8 cm H₂O for AFE/pulmonary oedema

C - Circulation

  • 2 large-bore IV cannulae (14-16G) in antecubital fossae
  • Bloods: FBC, coagulation screen, fibrinogen, U&E, LFTs, ABG, crossmatch 6 units, TEG/ROTEM
  • IV fluids: Crystalloids (Hartmann's/Normal Saline) for initial resuscitation
  • Vasopressors: Noradrenaline (first choice in septic/AFE collapse) OR Ephedrine/Phenylephrine (for spinal hypotension)
  • Invasive monitoring: Arterial line (radial - continuous BP + ABG sampling), CVP via internal jugular or subclavian
  • Urine output: Foley catheter - target >0.5 mL/kg/hr

D - Disability

  • GCS, pupils, blood glucose (hypoglycaemia can cause collapse)
  • Check for seizures (eclampsia)
  • Neurological status: posture, reflexes

E - Exposure + Environment

  • Full exposure, keep warm (warm IV fluids, warming blanket)
  • Examine for: uterine atony, retained placenta, perineal tears, uterine inversion

STEP 4 - INVESTIGATE TO IDENTIFY CAUSE

InvestigationPurpose
ABGHypoxia, acidosis, lactate
12-lead ECGPE (S1Q3T3), arrhythmia, MI
POCUS / Echo (bedside)RV dysfunction (AFE/PE), LV failure, pericardial effusion
Chest X-rayPulmonary oedema, pneumothorax
FBC + Coagulation + FibrinogenDIC (AFE, PPH, abruption)
TEG/ROTEMDirected blood product therapy
Blood culturesSepsis
Serum lactateTissue hypoperfusion

DIAGRAM 3 - Cause-Specific Anesthetic Management

Cause-Specific Management

STEP 5 - CAUSE-SPECIFIC MANAGEMENT IN DETAIL

5A. POSTPARTUM HAEMORRHAGE (PPH) - Most Common Cause

Miller's Anesthesia 10e, Creasy & Resnik Ch 70
  • Secure airway early if haemodynamic instability (RSI + ETT)
  • Uterotonic agents:
    • Oxytocin 20-40 units in 500 mL NS (slow infusion - avoid bolus as causes hypotension)
    • Ergometrine 0.2 mg IM (avoid in hypertension)
    • Carboprost 250 mcg IM every 15 min (max 8 doses; avoid in asthma)
    • Misoprostol 800-1000 mcg SL/PR
    • Tranexamic Acid (TXA) 1g IV within 3 hours (WHO recommended; repeat if bleeding continues at 30 min)
  • Massive Transfusion Protocol (MTP):
    • PRBC : FFP : Platelets = 1:1:1 ratio
    • Target fibrinogen >2g/L - give cryoprecipitate if <1.5g/L
    • Use TEG/ROTEM to guide ratios
    • Warm all blood products (hotline warmer)
  • Cell salvage - acceptable in PPH; use leucocyte depletion filter
  • Invasive options if pharmacological fails: Balloon tamponade, compression sutures, uterine artery ligation, interventional radiology (uterine artery embolisation), hysterectomy as last resort

5B. AMNIOTIC FLUID EMBOLISM (AFE)

Miller's Anesthesia 10e, Creasy & Resnik Ch 70
Diagnostic Criteria (SMFM/AFE Foundation):
  1. Sudden cardiorespiratory compromise
  2. DIC (documented)
  3. Onset during labour or within 30 min of placental delivery
  4. No other obvious diagnosis
Pathophysiology: Not truly embolic - abnormal maternal immune response to fetal material entering maternal circulation → SIRS-like cascade → right heart failure → DIC
Management:
  • Immediate CPR if cardiac arrest
  • Early intubation + 100% O₂ + PEEP
  • Vasopressors (noradrenaline) + Inotropes (dobutamine) for RV failure
  • Transoesophageal echocardiography post-intubation to assess RV function
  • Treat DIC: 1:1:1 blood products + cryoprecipitate; TEG/ROTEM guided
  • ECMO for persistent haemodynamic instability unresponsive to medical management
  • Avoid recombinant FVIIa - associated with major organ thrombosis and worse outcomes (Creasy & Resnik)

5C. MATERNAL CARDIAC ARREST

Creasy & Resnik Ch 70 - SOAP Consensus Statement
Key Differences from Standard ACLS:
  • No left uterine displacement needed postpartum (uterus involuting)
  • Standard CPR position (supine, firm surface)
  • Earlier and more aggressive airway management (high aspiration risk)
  • Chest compressions at same position as non-pregnant adults after delivery
  • Perimortem Caesarean Delivery - not needed postpartum (fetus already delivered)
  • CPR quality is compromised by transfer to OT - perform resuscitation at the bedside
Most common causes of maternal cardiac arrest (Nationwide Inpatient Sample):
  • PPH > Heart failure > AFE > Sepsis (Creasy & Resnik, PMID 36594762)
Survival rate: ~59% to hospital discharge (improving over time with ACLS training).

5D. PULMONARY EMBOLISM (PE)

  • Anticoagulate with unfractionated heparin IV (80 units/kg bolus then infusion)
  • If massive PE with haemodynamic collapse: IV thrombolysis (alteplase 100 mg over 2 hours)
  • Supportive: O₂, vasopressors, PEEP-cautious ventilation (avoid worsening RV afterload)
  • POCUS shows RV dilation, D-sign, McConnell's sign

5E. ECLAMPSIA

  • Secure airway (seizure risk → aspiration)
  • MgSO₄: 4-6g IV over 15-20 min loading dose, then 1-2g/hour infusion
  • Antihypertensives: Labetalol 20 mg IV or Hydralazine 5 mg IV if BP >160/110
  • Watch for: MgSO₄ toxicity (loss of patellar reflexes, respiratory arrest) - antidote is Calcium gluconate 10 mL 10% IV

5F. SEPTIC SHOCK

  • Sepsis-3 criteria: Suspected infection + organ dysfunction (SOFA ≥2)
  • 1-hour bundle: Blood cultures, lactate, broad-spectrum antibiotics (within 1 hour), 30 mL/kg crystalloid if lactate >4, vasopressors (noradrenaline)
  • Source control: drain collections, remove infected products of conception

5G. LOCAL ANAESTHETIC SYSTEMIC TOXICITY (LAST)

(If epidural catheter recently topped up)
  • Stop LA infusion immediately
  • Seizure: benzodiazepines; cardiac arrest: CPR
  • 20% Lipid emulsion (Intralipid): 1.5 mL/kg IV bolus over 1 min, then 0.25 mL/kg/min infusion
  • Avoid propofol as lipid substitute
  • May need prolonged CPR

STEP 6 - MONITORING

MonitorTarget
Arterial line (radial)Continuous BP, ABG sampling
SpO₂>95%
ETCO₂35-40 mmHg
Urine output>0.5 mL/kg/hr
CVP8-12 mmHg (fluid status)
TEG/ROTEMTargeted blood product therapy
Bedside POCUS/EchoCardiac function, RV strain
TemperatureNormothermia

STEP 7 - DEFINITIVE CARE

  • Transfer to ICU/HDU once stabilised
  • Multidisciplinary review: Obstetrician, Anaesthetist, Haematologist, Intensivist, Cardiologist (as needed)
  • Debrief the team and document clearly
  • Thromboprophylaxis as soon as haemostasis achieved
  • Family communication and psychological support
