Erratum
After publication of the original article [1], the authors noticed a mistake in Table 2. Patient numbers in lactate classification categories Low, Medium and High were incorrectly reported as forty one, seven and two respectively in the GEM 4000 column. The patient numbers that should have been reported in Table 2 are forty, three and seven. Table 2 appears in its correct form in this erratum.
Table 2
Lactate risk category classification determined by the i-STAT and the blood gas analysers
Risk category | i-STAT | GEM 4000 | Risk category | i-STAT | OMNI S |
|---|---|---|---|---|---|
Low <2.5 mmol/L (n = 40) | 40 | 40 | Low <2.5 mmol/L (n = 45) | 45 | 45 |
Medium 2.5 – 3.99 mmol/L (n = 3) | 3 | 3 | Medium 2.5 – 3.99 mmol/L (n = 2) | 2 | 2 |
High ≥4 mmol/L (n = 7) | 7 | 7 | High ≥4 mmol/L (n = 0) | 0 | 0 |
Additionally, the incorrect patient numbers from Table 2 were reported in the ‘Results’ section. The ‘Comparison of i-STAT against GEM premier 4000’ sub-section should therefore have read as follows:
Anzeige
“Among the 50 samples (from 11 ICU patients) analysed on the GEM 4000 and the i-STAT; there were forty samples classified as low, three samples as medium and seven samples as high lactate risk level categories.”
This mistake does not alter the validity of the results and conclusions as all lactate samples analysed on the i-STAT and GEM 4000 analysers fell in the same lactate risk categories.
