Objective: To study the effect and clinical value of serumÂ procalcitonin (PCT) markers combined with restrictive fluidÂ resuscitation in traumatic shock combined with intracranialÂ infection. Method:Â 33 patients with craniocerebral trauma admitted in our hospital from May 2015 to July 2016 were divided into control group (65 cases) without intracranial infection. The study group (cranial) Infection, 68 cases). The levelsÂ of serum PCT, WBC and C-reactive protein (CRP) in the twoÂ groups were measured and the working curve (ROC) of theÂ subjects was drawn to evaluate the diagnostic value of each index. To give traumatic shock combined with intracranial infection in patients with restrictive fluid resuscitation intervention,to explore clinical efficacy.
