Clinical value of bedside ultrasound measurements of inferior vena cava diameter and its rate of change in early fluid resuscitation in patients with severe traumatic brain injury.

Objective: To explore the clinical value of inferior vena cava diameter (IVCD) detection in guiding early fluid resuscitation in patients with severe traumatic brain injury (sTBI).

Methods: Eighty patients with sTBI admitted to our hospital from October 2018 to October 2021 were retrospectively enrolled and divided into an observation group (n=40) and control group (n=40) according to the different monitoring methods used for treatment. The cerebrospinal fluid (CSF) lactate level, coagulation function, neurological function, and functional impairment, organ, cognitive, living ability and physical condition, Glasgow score, and adverse reactions in two groups were compared.
