Background: Craniocerebral operation is the main method for the treatment of traumatic brain injury. However, it is very easy to be complicated with intracranial infection after operation, which affects the surgical efficacy and patient’s prognosis. It is also the main cause
of surgical failure. It may also cause patient’s death for some patients with serious diseases. It is found that the infection after craniocerebral operation is often accompanied with abnormal changes of body-related treatment, in which the changes of serological indicators are more
significant. Therefore, it is helpful to provide guidance for the prevention and judgment of patient’s postoperative infection by analyzing the patient’s serological indicators.
Objective: To investigate the risk factors of intracranial infection and the levels of serum
procalcitonin (PCT) and endothelin-1 (ET-1) in patients after traumatic brain injury.
Methods: From January 2018 to January 2021, 58 patients with intracranial infection after traumatic brain injury (infection group) were selected, and 116 patients without intracranial infection
after traumatic brain injury (non-infection group) were selected. The difference of clinical data between the two groups was analyzed. Serum PCT and ET-1 levels were measured in the two groups.
Results: In the infection group, admission GCS scoring <8 points, operation time ≥4h,
indwelling time of drainage tube ≥ 2d, preoperative ALB <35g/ L, mechanical ventilation and cerebrospinal fluid leakage were 63.79%, 72.41%, 43.10%, 68.97%, 32.76% and 68.97% respectively, which were obviously higher than those in the non-infection group (P<0.05). Logistic regression
analysis results showed that admission GCS scoring, operation time, indwelling time of drainage tube, preoperative ALB, mechanical ventilation and cerebrospinal fluid leakage were the influencing factors of intracranial infection after traumatic brain injury (OR = 0.712,1.556,1.451,0.641,1.954
and 1.667, P<0.05); serum PCT and ET-1 in the infection group were (0.83 ± 0.20) mg/L and (0.87 ± 0.23) ng/L, respectively, which were significantly higher than those in the non-infection group (P<0.05); serum PCT and ET-1 in patients with different sex, age and pathogen
had no significant difference (P>0.05); serum PCT and ET-1 area under ROC curve were 0.828 and 0.751, respectively P<0.05.
Conclusion: The intracranial infection of patients with traumatic brain injury are affected by many factors including, admission GCS scoring, operation
time, and so on, the levels of serum PCT and ET-1 in patients with intracranial infection are increased, which may be useful in predicting intracranial infection.
