Understanding near hanging. a meta-analysis and discussion of the anatomy, physiology, psychological outcomes, nursing interventions and care needs
Abstract
Abstract Suicide is a significant public health concern. Attempted suicide by means of hanging is frequently lethal and in Australia it is the most common method of attempting suicide. For those who survive and reach hospital the outcomes can be favourable but are variable. With active and aggressive treatment, it is possible for individuals to make a full recovery despite what is often a dismal and futile presentation. Hanging is a form of asphyxia that occurs when there is constriction of the neck, secondary to the tightening of a ligature under the gravitational weight of the body wholly or part. There are rarely catastrophic structural injuries or instantaneous death associated with “non-judicial” hanging. The process, physics and biomechanics inevitably differ significantly from modern judicial hanging, where death is almost instantaneous. Individuals who survive a hanging episode and reach hospital are referred to as having experienced a near hanging. For this cohort of individuals, those who experienced asphyxia and cardiac arrest are most likely to experience a poor outcome. Despite a limited body of literature this study aims to analyse the available research related to near hangings, with a focus on nursing care and interventions. Methods This work followed three stages: (a) establishing a clear question; (b) undertaking a systematic search of studies that utilised standardised data (c) analysis and interpretation of findings. As a meta-analysis this study used…
