RESUMO
@#Objective To analyze general and trace elements in cerebral spinal fluid (CSF)of patients with spinal cord injury (SCI). Methods To assess contents of general and trace elements (K, Na, Ca, Mg, Zn, Mn, Fe, Cu) in CSF of six SCI patients using ICP-AES. Results Compared with normal value, contents of Ca and Zn were significantly decreased (P<0.01), Fe and Mn were significantly increased (P<0.01), but no significant differences for Na, Mg, K and Cu in CSF of SCI patients. Conclusion The excitation of central nerve system in SCI patients may be higher than normal people indeed.
RESUMO
OBJECTIVE: To investigate the relationship between Injury Severity Score (ISS) and Acute Physiology and Chronic Health Evaluation (APACHE II) scores and mortality rate, and to evaluate the practical significance of APACHE II in ICU trauma patients. METHODS: ISS and APACHE II scores and mortality rate of 50 ICU trauma patients were calculated by AIS-1985 revision and Knaus method, then, compared and analyzed. RESULTS: The mortality rate was directly proportional to ISS and APACHE II scores in ICU trauma patients. APACHE II was more accurate and sensitive compared to ISS. CONCLUSIONS: APACHE II is a better predictor for ICU trauma patients. ISS>=25 or APACHE II>=20 may be used as the admitting criteria for ICU trauma patients.
