Hanging
Hanging is the most common form of suicide in the UK, especially in males and the younger population. This means that ambulance clinicians are likely to be exposed at some point in their career to cases of hanging.
When people think of hanging they often think of a long drop judicial style hanging from height, however it is much more likely that short drop or lean in hangings will be what is encountered.
Hanging can rapidly lead to cardiac arrest and the mechanism of this involves loss of consciousness from compression of the neck structures and anoxia which will eventually lead to a hypoxic myocardium +/- vagal impact.
Contrary to common belief c-spine injuries are rare unless a long drop MOI and whilst should be considered, should not prevent more important management and care.
When cutting down patients found hanging try where possible to cut the bite of the ligature in the loop and not the knot itself, for forensic reasons.
But remember life preservation is always the priority. Manage patients in cardiac arrest as a hypoxic reversible cause. Whilst VF can occur early, often PEA/ Asystole is the more common initial rhythm.
Good airway management and oxygenation is essential to care. Consider requesting additional assets such as critical care as intubation or need for surgical airway may be required, however in the main simple adjuncts and IGELs will be more than sufficient especially in the cardiac arrest phase of care.
Gain early IV/IO access and give adrenaline early.
Be prepared for an early ROSC and plan egress. If ROSC is achieved manage this the same a traumatic brain injury. Provide oxygen, maintain sats to 95-98%. possibly avoid c-spine collars, raise head up 30 degrees and prevent high temp development.
Strongly consider critical care for early as PHEA is beneficial for brain protection.
In the presence of bradycardia / hypotension Use fluids cautiously due to the risk of development of pulmonary oedema, instead consider the use of post rosc adrenaline.
If appropriate family and those on scene may be refered to support avenues.
