Here is a comprehensive clinical overview of near-hanging / suicidal hanging management, synthesized from Tintinalli's Emergency Medicine and Rosen's Emergency Medicine:

Near-Hanging: Emergency Management

Pathophysiology

Hanging is the second most common method of suicide death in the United States. Death in strangulation/hanging is primarily due to cerebral anoxia and ischemia, with the dominant mechanism being:

Venous compression → cerebral venous congestion → edema → unconsciousness (requires only minimal external pressure on the jugular veins)
Loss of muscle tone → arterial compression → cerebral anoxia
Airway obstruction and carotid body reflex-mediated cardiac dysrhythmia — minor contributors

Cervical spine fractures ("hangman's fracture") occur primarily in judicial/long-drop hangings. Short-drop suicidal hangings rarely cause significant spinal cord injury.

Additional injuries include:

Laryngotracheal fractures
Hyoid bone fracture (classically associated, but present in a minority)
Pharyngeal lacerations
Carotid artery dissection (rare; suspect if lateralizing neuro deficits or carotid bruising)

Clinical Features

Category	Features
Common complaints	Neck pain, voice changes, dysphagia, dyspnea
Physical signs	Petechiae, neck contusions, ligature marks, facial edema
Warning sign	~50% of victims have NO visible neck trauma, ~2/3 are asymptomatic
Hard signs (see table below)	Stridor, hoarseness, altered mental status, cyanosis, stroke-like symptoms

Prognosis pearls:

Patients presenting in cardiac arrest have a dismal prognosis.
Neurologic recovery is unpredictable — severe GCS 3 may fully recover; normal exam patients may deteriorate.
Delayed cerebral or pulmonary edema can kill seemingly asymptomatic patients.

Hard Signs of Strangulation Injury (Tintinalli Table 260-10)

Head/Neck/ENT:

Visual disturbances
Conjunctival or facial petechial hemorrhages
Swollen tongue/oropharynx
Hoarseness or stridor
Subcutaneous edema or crepitus
Tenderness over larynx
Neck ligature marks, abrasions, edema

Cardiovascular/Respiratory:

Cyanosis or hypoxia
Arrhythmias
Respiratory distress, crackles, wheezes

Neurologic:

Altered mental status
Seizures
Stroke-like symptoms
Incontinence

Diagnosis

CT neck (soft tissue): Detects intramuscular hemorrhage/edema, subcutaneous bleeding, platysma swelling, hemorrhagic lymph nodes
CT brain: Assess for cerebral edema or anoxic injury
Carotid imaging (CT angiography): Indicated if neurologic deficits are discordant with brain CT — to exclude carotid dissection
Laryngobronchoscopy: For dyspnea, dysphonia, aphonia, odynophagia — may reveal petechiae, edema, vocal cord paralysis
ECG: For arrhythmia detection
Cervical spine imaging: Particularly in judicial/long-drop hangings

Treatment & Disposition

Immediate Priorities

Scenario	Action
Cardiac arrest	CPR; poor prognosis
Unconscious or progressive symptoms (odynophagia, hoarseness, neuro changes, dyspnea)	Aggressive airway management (early intubation — the airway can worsen rapidly from edema)
Pulmonary edema	PEEP ventilation
Cerebral edema	ICP reduction strategies, seizure prophylaxis

Airway Management

Early, definitive airway control is critical — edema can rapidly progress and make later intubation impossible. Have surgical airway backup ready.

Cervical Spine

Immobilize as a precaution, especially in long-drop hangings. Short-drop suicidal hangings have low risk for spinal injury but do not delay resuscitation for spinal precautions.

Disposition

Clinical Status	Disposition
Hard signs or abnormal imaging	Admit to appropriate service/ICU
Symptomatic with normal imaging	Observe
Asymptomatic, no hard signs	May discharge only if social support available; provide strict return precautions

All patients must be counseled about possible delayed respiratory and neurologic dysfunction.

Psychiatric / Psychosocial Management

This is a mandatory component of care.

All survivors of hanging require formal psychiatric evaluation
Hangings are often part of a complex suicide attempt — assess for other concurrent self-harm (wrist lacerations, ingestions, gunshot wounds, stab wounds)
Suicide risk remains high after discharge — arrange outpatient mental health follow-up within 72 hours
Employ Joint Safety Planning (not a "no-suicide contract," which lacks evidence and may cause harm)
Conduct lethal means restriction counseling — one of the two suicide prevention interventions with strong empirical evidence
