Postpartum complication

A streamlined, differential-led presentation for rapid clinical review.

Clinical snapshot

Twenty-second review

  • Postpartum emergencies include hemorrhage, infection, hypertensive disease, cardiomyopathy, and thromboembolism during a period of major vascular and physiological change.
  • Heavy bleeding, shock, severe headache, seizure, dyspnea, chest pain, fever, or altered LOC is time-critical.
  • Keep anxiety or musculoskeletal pain in the differential; overlapping or concurrent illness remains possible.
  • For postpartum complication, trends and combinations of findings are more informative than one isolated vital sign.

The repeated material is grouped inside each possibility. Open only the condition you need.

Serious5 conditions
Postpartum hemorrhageTime-sensitive high-risk possibility

HPI

Clarify delivery date and type; bleeding amount and clots; pain, fever or headache.

Signs & symptoms

Bleeding, hypertension symptoms, dyspnea, fever, or shock.

Focused exam

Assess abdominal tenderness, fundal height or contractions when appropriate, visible bleeding, perineal findings only when necessary, and maternal perfusion; Preserve privacy and use a chaperone or support person when possible.

Brief pathophysiology

Postpartum hemorrhage may cause postpartum complication through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Hemorrhage is a trend diagnosis: tachycardia and narrowing pulse pressure may precede hypotension. Age, pregnancy, medications, and pacing can blunt expected responses.

Heart rate (bpm)

Often rises

Tachycardia is a common compensatory response but may be absent.

Pulse pressure (mmHg)

May narrow

Narrowing pulse pressure can reflect reduced stroke volume.

Blood pressure (mmHg)

May fall late

A normal pressure does not exclude significant compensated hemorrhage.

MAP (mmHg)

May fall

A falling trend supports worsening perfusion; interpret with mental status and skin signs.

EclampsiaTime-sensitive high-risk possibility

HPI

Clarify bleeding amount and clots; pain, fever or headache; blood pressure and perfusion.

Signs & symptoms

Bleeding, hypertension symptoms, dyspnea, fever, or shock.

Focused exam

Preserve privacy and use a chaperone or support person when possible; Determine time since birth, quantify bleeding, assess uterine or abdominal pain, BP symptoms, lungs, edema, DVT signs, wound, and infant context.

Brief pathophysiology

Eclampsia may cause postpartum complication through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Pregnancy changes baseline physiology and can mask blood loss. Trend heart rate, pressure, breathing, and oxygenation in gestational and postpartum context.

Heart rate (bpm)

Use pregnancy baseline

A modestly higher baseline is common; disproportionate tachycardia can signal bleeding or illness.

Blood pressure (mmHg)

Trend carefully

Hypotension may be late in hemorrhage; hypertension may indicate a pregnancy-specific emergency.

Respiratory rate (breaths/min)

Trend rate / effort

Tachypnea may reflect pain, shock, PE, or systemic illness.

Oxygen saturation (SpO₂)

Usually preserved

Low saturation requires assessment for PE, pulmonary edema, or respiratory disease.

Front-load in the triage report

  • Eclampsia: Bleeding, hypertension symptoms, dyspnea, fever, or shock.
  • Bleeding amount and clots?
  • Pain, fever or headache?
PETime-sensitive high-risk possibility

HPI

Clarify pain, fever or headache; blood pressure and perfusion; pregnancy complications.

Signs & symptoms

Bleeding, hypertension symptoms, dyspnea, fever, or shock.

Focused exam

Preserve privacy and use a chaperone or support person when possible; Determine time since birth, quantify bleeding, assess uterine or abdominal pain, BP symptoms, lungs, edema, DVT signs, wound, and infant context.

Brief pathophysiology

PE may cause postpartum complication through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

Pulmonary embolism may have normal observations. Tachycardia, tachypnea, or hypoxemia increase concern; hypotension identifies hemodynamic compromise rather than being required for diagnosis.

Heart rate (bpm)

May rise

Tachycardia is common but neither sensitive nor specific.

Respiratory rate (breaths/min)

May rise

Tachypnea may be an early sign of increased ventilatory demand.

Oxygen saturation (SpO₂)

May fall

Hypoxemia may occur, but a normal saturation does not exclude PE.

Blood pressure (mmHg)

Often preserved

Hypotension suggests high-risk PE with obstructive shock.

Front-load in the triage report

  • PE: Bleeding, hypertension symptoms, dyspnea, fever, or shock.
  • Pain, fever or headache?
  • Blood pressure and perfusion?
SepsisTime-sensitive high-risk possibility

HPI

Clarify blood pressure and perfusion; pregnancy complications; newborn location and supports.

Signs & symptoms

Bleeding, hypertension symptoms, dyspnea, fever, or shock.

Focused exam

Preserve privacy and use a chaperone or support person when possible; Determine time since birth, quantify bleeding, assess uterine or abdominal pain, BP symptoms, lungs, edema, DVT signs, wound, and infant context.

Brief pathophysiology

Sepsis may cause postpartum complication through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern

What the trend may show

Possible pattern

No single vital sign diagnoses sepsis. New tachypnea, abnormal temperature, tachycardia, or falling pressure—especially with altered mentation or poor perfusion—supports organ dysfunction and urgency.

Respiratory rate (breaths/min)

May rise early

Tachypnea is included in NEWS2 and can precede overt hypotension.

Temperature (°C)

High or low

Absence of fever does not exclude sepsis; hypothermia is concerning.

Heart rate (bpm)

Often rises

Tachycardia is common but may be blunted by age or medication.

Blood pressure (mmHg)

May fall

Relative hypotension and trend matter; profound hypotension can be late.

  • Blood pressure and perfusion?
  • Pregnancy complications?

Brief pathophysiology

Cardiomyopathy may cause postpartum complication through a time-sensitive process capable of rapid physiological deterioration.

Vital-sign pattern
