Platelet parameters of 40 healthy subjects served as controls. Platelet number was decreased, while mean platelet volume and platelet distribution width values were increased, at 1 and 3 days after injury. Platelet number was lower and mean platelet volume and platelet distribution width were larger in patients with traumatic cerebral infarction and those in Glasgow Coma Scale score 〈 8 group. Platelet number was negatively correlated to volume of cerebral edema, but positively correlated to Glasgow Outcome Scale score. These data indicate that changes in platelet parameters may be utilized to indicate the state of central nervous system injury and patient prognosis .展开更多

文摘Background：Decreased platelet （PLT） count is one of the independent risk factors for mortality in intensive care unit （ICU） patients.This study was to investigate the relationship between PLT indices and illness severity and their performances in predicting hospital mortality.Methods：Adult patients who admitted to ICU of Changzheng Hospital from January 2011 to September 2012 and met inclusion criteria were included in this study.Univariate analysis was used to identify potential independent risk factors for mortality.Multiple logistic regression analysis was used to calculate adjusted odds ratio for mortality in patients with normal or abnormal PLT indices.The relationship between PLT indices and illness severity were assessed by the Acute Physiology and Chronic Health Evaluation Ⅱ （APACHE Ⅱ） scores or sequential organ failure assessment （SOFA） scores in patients with normal and abnormal PLT indices.The performances of PLT indices in predicting mortality were assessed by receiver operating curves and diagnostic parameters.The survival curves between patients with normal and abnormal PLT indices were compared using Kaplan-Meier method.Results：From January 2011 to September 2012,261 of 361 patients （204 survivors and 57 nonsurvivors） met the inclusion criteria.After adjustment for clinical variables,PLT count 〈 100 × 10^12/L （P =0.011）,plateletcrit （PCT） 〈0.108 （P =0.002）,mean platelet volume （MPV） 〉11.3 fL （P =0.023） and platelet distribution width （PDW） percentage 〉17% （P =0.009） were identified as independent risk factors for mortality.The APACHE Ⅱ and SOFA scores were 14.0 （9.0-20.0） and 7.0 （5.0-10.5） in the ＂low PLT＂ tertile,13.0 （8.0-16.0） and 7.0 （4.0-11.0） in the ＂low PCT＂ tertile,14.0 （9.3-19.0） and 7.0 （4.0-9.8） in the ＂high MPV＂ tertile,14.0 （10.5-20.0） and 7.0 （5.0-11.0） in the ＂high PDW＂ tertile,all of which were higher than those in patients with normal indices.Patients with decreased PLT and PCT values （all P 〈 0.001）,or increased MPV and PDW values （P =0.007 and 0.003,respectively） had shortened length of survival than those with normal PLT indices.Conclusions：Patients with abnormally low PLT count,high MPV value,and high PDW value were associated with more severe illness and had higher risk of death as compared to patients with normal PLT indices.
