Abstract:
Objective:To investigate the relationship between adenosine diphosphate (ADP) pathway-induced platelet dysfunction monitoring by thrombelastography with hospital mortality in patients with traumatic brain injury.Methods:The clinical data of 180 patients with traumatic brain injury in Zhejiang Quhua Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients underwent thrombelastography examination. Among them, the ADP pathway-induced platelet inhibition rate (ADP inhibition rate) ≤ 60% was in 74 cases (non-ADP dysfunction group), and ADP inhibition rate > 60% was in 106 cases (ADP dysfunction group). Multiple Logistic regression analysis was used to analyze the independent influencing factors of patients′ hospital mortality. Logistic regression model was used to analyze the threshold of ADP inhibition rate to predict hospital mortality.Results:There were no statistical differences in the gender composition, age, prothrombin time, international standardized ratio, activated partial thromboplastin time, platelet count, systolic blood pressure, pulse, admission to thrombelastography examination time, Glasgow coma score, trauma severity score, simple trauma grading criteria and using of antiplatelet drugs before admission between 2 groups ( P>0.05). The intubation rate and in-hospital mortality in ADP dysfunction group were significantly higher than those in non-ADP dysfunction group: 69.8% (74/106) vs. 37.8% (28/74) and 32.1% (34/106) vs. 8.1% (6/74), and there were statistical differences ( P<0.01 or <0.05). The maximum amplitude and G value in ADP dysfunction group were significantly lower than those in non-ADP dysfunction group: (61 ± 9) mm vs. (65 ± 6) mm and (9 ± 4) kD/cm2 vs. (11 ± 3) kD/cm2, the ADP inhibition rate and arachidonic acid pathway-induced platelet inhibition rate were significantly higher than those in non-ADP dysfunction group: (76 ± 22)% vs. (45 ± 18)% and (75 ± 28)% vs. (35 ± 22)%, and there were statistical differences ( P<0.05). There were no statistical difference in the reaction time, blood clot formation time and angle between 2 groups ( P>0.05). Multiple Logistic regression analysis result showed that ADP inhibition rate >60% and trauma severity score were independent predictors of increased hospital mortality in patients with traumatic brain injury ( OR = 6.21 and 1.13, 95% CI 1.21 to 31.27 and 1.05 to 1.22, P<0.05). Logistic regression model analysis result showed that ADP inhibition rate >60% was the threshold for predicting the hospital mortality rate ( OR = 6.18, 95% CI 1.2 to 33.3). Conclusions:ADP inhibition rate of thrombelastography is related to the hospital mortality in patients with traumatic brain injury.
