Pertinent laboratory characteristics
| With abscess (n = 10) | Without abscess (n = 36) | |
|---|---|---|
| Data are expressed as mean (SD), except the duration of bacteraemia which is median (range). | ||
| *p<0.012; **p<0.03. Kruskal Wallis and t tests were used to study differences between infants with and without abscesses. Backward stepwise regression analysis was used to study the independent impact of these variables on mortality. p < 0.05 was considered significant. | ||
| White blood cells (× 103/μl) | 34.8 (18.3) | 27.4 (22.2) |
| Absolute granulocytes (× 103/μl) | 14.8 (17.6) | 16.7 (17.5) |
| Platelets (× 103/μl) | 95 (124)* | 247 (159) |
| pH at onset of sepsis | 7.31 (0.04) | 7.26 (0.11) |
| Pco2 at onset of sepsis (mm Hg) | 43 (8) | 47 (12) |
| Duration of bacteraemia (days) | 6 (6–20)** | 4 (1–9) |
