Summary
Near-hanging injuries are life-threatening, with cardiac arrest being a major cause of mortality. Survivors of near-hanging events, however, show excellent neurocognitive recovery, highlighting the need for protective strategies.
Area of Science:
- Critical Care Medicine
- Neurology
- Toxicology
Background:
- Near-hanging incidents represent severe, life-threatening events with limited available data.
- Understanding outcomes and predictors of mortality in critically ill patients following near-hanging is crucial.
Purpose of the Study:
- To investigate the outcomes and early predictors of hospital mortality in critically ill patients who experienced near-hanging.
- To identify factors associated with vital and functional outcomes at hospital discharge.
Main Methods:
- Retrospective analysis of adult patients successfully resuscitated after suicidal near-hanging injury across 31 French and Belgian ICUs (1992-2014).
- Utilized International Classification of Diseases codes and hospital charts for patient identification.
- Logistic multivariate regression was employed to determine predictors of mortality and outcomes.
Main Results:
- Of 886 patients, 50.8% experienced cardiac arrest due to hanging. Hospital mortality was 43.9%.
- Survivors (56.1%) demonstrated a high rate of favorable neurocognitive outcome (96.4%).
- Predictors of mortality included hanging-induced cardiac arrest, elevated ICU glycemia (>1.4 g/L), and elevated ICU lactate (>3.5 mmol/L).
Conclusions:
- Near-hanging injuries carry a high mortality risk, primarily due to cardiac arrest.
- Patients surviving near-hanging events exhibit remarkable neurocognitive recovery.
- Further research into early neuroprotective strategies for near-hanging survivors is warranted.

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI.
