A prospective study was conducted for 91 cases of fever patients after neurosurgical procedures during the period of January-December 2013.They were divided into non-infection (n =42) and infection (n =49) groups according to whether there was infection complication.And another 51 nonsurgical hospitalized patients without fever or infection were selected as control group.The levels of procalcitonin (PCT),C-reactive protein (CRP) and white blood cell (WBC) were detected respectively.Statistical analysis showed that the level of PCT had no significant difference between non-infection and control groups (P ＞ 0.05).However,it was markedly elevated in infection group than non-infection group (P ＜ 0.01).The level of CRP was significantly different between non-infection and control groups (P ＜ 0.01).And it was the same between infection and non-infection groups.The level of WBC had significant difference between non-infection and control groups (P ＜ 0.05) and infection and non-infection groups (P ＜ 0.01).The receiver operating characteristic (ROC) curve showed that either sensitivity or specificity of PCT was the highest.Compared with CRP and WBC,PCT may identify more accurately the causes of fever after neurosurgical procedures.

Objective To investigate the prevention and treatment for complications of chronic subdural hematoma using intracranial puncture and drainage. Methods Clinical data of 210 cases of chronic subdural hematoma treated by puncture and drainage were studied retrospectively. Results The cure rate was 97 1% (204/210), the recurrence rate was 7 1% (15/210), the incidence of complications was 14 3% (30/210), and the mortality, 0 95% (2/210). Conclusions Intracranial puncture and drainage for chronic subdural hematoma is safe, simple and effective. Prompt and proper treatment for complications encountered is required to obtain an excellent therapeutic effect.
