Suicide by hanging
is often considered to be a simple suicide method that does not require complicated techniques; a study of people who attempted suicide by hanging and lived usually suggests that this perception may not be accurate. It is one of the most commonly used suicide methods and has a high mortality rate; Gunnell et al. gives a figure of at least 70 percent. The materials required are easily available, making it a difficult method to prevent. In the International Statistical Classification of Diseases and Related Health Problems, suicides by hanging are classified under the code X70: "Intentional self-harm by hanging, strangulation, and suffocation."
Hanging is divided into suspension hanging and the much rarer drop hanging — the latter can kill in various ways. People who survive either because the cord or its anchor point of attachment breaks, or because they are discovered and cut down, can face a range of serious injuries, including cerebral anoxia, laryngeal fracture, cervical fracture, tracheal fracture, pharyngeal laceration, and carotid artery injury. Ron M. Brown writes that hanging has a "fairly imperspicuous and complicated symbolic history". There are commentaries on hanging in antiquity, and it has various cultural interpretations. Throughout history, numerous famous people have died due to suicide by hanging.
Medical effects and treatment
People who survive hanging report seeing flashing lights and hearing ringing sounds.The neck of people who are hanged are usually marked with furrows where the ligature had constricted the neck. An inverted V mark is also often seen. Because of the pressure on the jaw, the tongue is sometimes protruding, causing it to dry. Depending on the circumstances, petechiae may be present on the eyes, face, legs, and feet. Cervical fractures of the spine are rare unless the hanging is a drop hanging, which usually causes an injury known as hangman's fracture. Suspension hanging usually results in cerebral hypoxia and decreased muscle tone around the neck. According to Aufderheide et al., the most common cause of death of hangings is cerebral hypoxia.
Most people who are hanged die before they are found; the term "near hanging" refers to those who survive. Initial treatment of survivors follows the "usual priorities of airway, breathing, and circulation ". Treatment should be "directed at airway control with endotracheal intubation, ventilation using positive end expiratory pressure, and hyperventilation with supplemental oxygen to control intracranial pressure". One study of people who experienced near-hanging who were treated appropriately at a hospital found that 77 percent of them survived.
Prevalence
According to Anton J. L. van Hooff, hanging was the most common suicide method in primitive and pre-industrial societies. A 2008 review of 56 countries based on World Health Organization mortality data found that hanging was the most common method in most of the countries, accounting for 53 percent of the male suicides and 39 percent of the female suicides.In England and Wales, hanging is the most commonly used method, and is particularly prevalent in the group of males aged 15–44, comprising almost half of the suicides in the group. It is the second most common method among women, behind poisoning. In 1981 hanging accounted for 23.5 percent of male suicides, and by 2001 the figure had risen to 44.2 percent. The proportion of hangings as suicides in 2005 among women aged 15–34 was 47.2 percent, having risen from 5.7 percent in 1968. In the United States it is the second most common method, behind firearms, and is by far the most common method for those in psychiatric wards and hospitals. Hanging accounts for a greater percentage of suicides among younger Americans than among older ones. Differences exist among ethnic groups; research suggests that hanging is the most common method among Chinese and Japanese Americans. Hanging is also a frequently used method for those in custody, in several countries.
