Neuropsychiatric symptoms in the context of hemodynamic disruption during septic shock

Septic shock represents one of the most severe critical illness types, characterized by significant hemodynamic disorders and neuropsychiatric symptoms. This study aimed to investigate the association mechanism between hemodynamic indicators and neuropsychiatric symptoms in patients with septic shock, revealing potential pathophysiological connections.

To investigate the link between hemodynamic parameters and neuropsychiatric symptoms in septic shock.

A retrospective case-control study involving 132 patients with septic shock. Multiple assessment tools were employed, including the Confusion Assessment Method, Hospital Anxiety and Depression Scale, Posttraumatic Stress Disorder Scale, and Mini-Mental State Examination, systematically evaluating patients' neuropsychiatric symptoms and hemodynamic indicators.

Patient mean age was 52.4 ± 12.3 years, with 68.5% males. Multivariate analysis revealed significant correlations between neuropsychiatric symptom severity and mean arterial pressure < 65 mmHg [odds ratio (OR) = 2.7], lactate levels > 4 mmol/L (OR = 3.1), and elevated interleukin-6 inflammatory factors (OR = 2.4). Neuropsychiatric symptom incidence rates were: Delirium 37.1%; anxiety 28.8%; depression 24.2%; and posttraumatic stress disorder 19.7%.

Hemodynamic disorders in patients with septic shock are closely associated with neuropsychiatric symptoms, influencing central nervous system function through complex inflammatory and neurotransmitter pathways.
