What is the appropriate emergency and subsequent management for a patient who attempted hanging?

Management of Hanging Patient

Immediately assess responsiveness and pulse while simultaneously checking for breathing; if no pulse is present, activate emergency response and begin CPR with 30 compressions to 2 breaths, prioritizing chest compressions over airway concerns. 1

Initial Assessment and Resuscitation

Primary Survey (First 10 Seconds)

• Check responsiveness by shaking shoulders and shouting 1
• Simultaneously assess breathing and pulse within 10 seconds 1
• Activate emergency response system immediately if cardiac arrest is identified 1

If Cardiac Arrest Present (No Pulse or Only Gasping)

• Start CPR immediately with cycles of 30 chest compressions to 2 breaths 1
• Push hard and fast: at least 2 inches (5 cm) depth at 100-120 compressions/minute 1
• Minimize interruptions in chest compressions 1
• Use AED as soon as available 1
• Administer epinephrine 1 mg IV/IO every 3-5 minutes once vascular access obtained 1

If Pulse Present But Not Breathing Normally

• Provide rescue breathing at 1 breath every 6 seconds (10 breaths/minute) 1
• Recheck pulse every 2 minutes; if lost, immediately start CPR 1
• Maintain head tilt-chin lift to keep airway open 1

Airway Management Considerations

Critical Airway Decision Points

Cervical spine injury is rare in hanging victims (no documented cases in transported patients in one 12-year study), making cerebral hypoxia—not spinal injury—the primary concern. 2

• Perform oral or nasal endotracheal intubation following external neck stabilization if advanced airway needed 2, 3
• Do not delay intubation for cervical spine imaging in critically ill patients 2, 3
• Use head tilt-chin lift maneuver as primary airway opening technique 1
• Consider jaw thrust without head extension only if high suspicion for cervical injury, but switch to head tilt-chin lift if airway remains obstructed 1

Indications for Immediate Intubation

• Glasgow Coma Scale <8 1
• Loss of protective laryngeal reflexes 1
• Inability to maintain PaO2 ≥13 kPa (aim SpO2 ≥95%) 1
• Hypercarbia (PaCO2 >6 kPa) or spontaneous hyperventilation (PaCO2 <4.0 kPa) 1

Post-Resuscitation Management

Aggressive Supportive Care Regardless of Initial Presentation

Aggressively resuscitate all near-hanging patients irrespective of dismal initial presentation, as poor initial neurological status does not exclude good recovery. 4, 3

• Initial neurological assessment has limited prognostic value 3
• Optimize cerebral oxygenation as primary goal 2, 3
• Monitor for pulmonary complications: pulmonary edema (neurogenic or negative pressure) and aspiration pneumonia are leading causes of in-hospital death 3

Monitoring and Complications

• Laryngotracheal injuries are infrequent in survivors (20-50% at autopsy but rare clinically) and rarely interfere with airway management 3
• Exclude cervical spine injury but do not delay resuscitation for imaging 3
• Anticipate pulmonary edema which may develop from neurogenic mechanisms or negative intrathoracic pressure 3

Therapies NOT Recommended

Do not use hyperbaric oxygen, therapeutic hypothermia, or targeted temperature management in cardiac arrest patients post-hanging, as insufficient evidence supports survival benefit. 5

Common Pitfalls to Avoid

• Do not prioritize airway maneuvers over chest compressions in cardiac arrest—the CAB (compressions-airway-breathing) sequence takes precedence 1
• Do not assume poor prognosis based on initial presentation; survivors with initially poor Glasgow Coma Scale can achieve full neurological recovery 4, 3
• Do not delay intubation for cervical spine clearance when airway protection is needed, as spinal injury is exceedingly rare in survivors 2, 3
• Do not use excessive tidal volumes during ventilation; 500-600 mL (6-7 mL/kg) is sufficient during CPR 1
