RESUMO
Objective:To explore the value of Glasgow coma score (GCS) combined with optic nerve sheath diameter (ONSD) in predicting the death risk of patients with cerebrocardiac syndrome (CCS).Methods:From January 2021 to September 2021, 83 patients with CCS secondary to severe traumatic brain injury (sTBI) in our hospital were collected and divided into a survival group ( n = 37) and death group ( n = 46) according to CCS-related death. The clinical data including age, sex, underlying diseases, head CT imaging manifestations, electrolytes, blood glucose, C-reactive protein (CRP), neuron-specific enolase (NSE), lactate dehydrogenase (LDH), creatine kinase (CK), creatine phosphokinase isoenzyme (CKMB), intracranial pressure (ICP), ONSD, cardiac color ultrasound, acute physiology and chronic health evaluationII (APACHEⅡ ) and GCS were analyzed and compared between the two groups. The proportion and dosage of vasoactive drugs used at admission, daily fluid balance volume during hospitalization, total amount of sedative and analgesic drugs, and average daily dose were analyzed and compared between the two groups. The independent risk factors for CCS-related death were analyzed using multivariate logistic regression. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of the independent risk factors in CCS-related death. Results:In this study, 55.4% of the patients died of CCS. The ONSD, ICP change rate, right ventricular Tei index and NSE in the death group were higher than those in the survival group, with statistically significant differences ( P < 0.05), while the GCS in the death group was significantly lower than that in the survival group, with a statistically significant difference ( P < 0.01). ONSD ( OR = 23.890, 95% CI: 5.526-103.286, P < 0.001), GCS ( OR = 17.066, 95% CI: 1.476-197.370, P = 0.023) and ICP change rate ( OR = 0.060, 95% CI: 0.007-0.477, P = 0.008) were the independent risk factors for CCS-related death. The area under the ROC curve (AUC = 0.897) of ONSD combined with GCS in evaluating CCS-related death was larger than that of ONSD, ICP change rate alone and the corresponding AUC of 1/GCS (0.876, 0.785, 0.800, respectively), with the advantages of non-invasive, dynamic monitoring and low inspection costs. Conclusions:The mortality rate of CCS is high. ONSD, GCS and ICP change rates are independently correlated with the death of CCS patients. ONSD combined with GCS is an ideal indicator for clinical prediction of CCS-related death.
