摘要: 276 LP attempts were examined prospectively by physician questionnaire and medical record review. Factors occurring at the time of as well required for CSF receipt laboratory (DEL) compared with clinical variables. Occurrence traumatic increased decreasing experience level person performing (p=0.04) younger patient age (p=0.0002). DEL averaged 28 min, 73% samples ≤ 30 min but 11.5% ≥ 60 DEL. A standard correction formula using RBC count blood WBC counts specimens 10,000 resulted in 11/15 (73%) non-M negative corrected HBC. Percent fresh ranged from 0 to 100 did not correlate (r=0.02). 2 48 M patients had or normal this formula. WBC. Linear regression analysis multiple independent variables (CSF RBC, WBC, DEL) failed produce a meaningful (r=0.47 best fit). Over-correction is likely occur explained Determination percent helpful interpretation suspected M. Mathematical models correct trauma are clinically useful should be used.
