Serial lactate and prognosis in intensive care patients
Critical Care volume 5, Article number: P89 (2001)
(1) To verify if the two first dosages of Lact were different between survivors (S) and nonsurvivors (NS), and (2) to verify whether there is difference between S and NS at ICU in relation to the temporal variation of Lact levels in the first 24 h of ICU admission.
This was a prospective study includinsg all patients admitted to the ICU during a 3-month period. Lact measurements were done (mmol/l) at ICU admission (LADM) and in the in the 3 following days (L1, L2, L3) according to the laboratory routine, making a total of until four measures per patient. The exclusion criteria were brain death at admission and patients who discharged or died before the L1 dosage. Demographic data were collected. Lact was compared between S and NS in four ways: LADM; L1; mean Lact; and variation between LADM and L1 in time by calculating the area under the curve. Data were analyzed using the package Statistica v5.0®. Means were compared using the nonpaired t-student test, and a P < 0.05 was considered statistically significant.
A total of 90 patients were analyzed. Eleven (12%) were NS.
The dosages of Lact at admission, L1, mean Lact and permanence of high levels of Lact in the first hours in the ICU were different between S and NS, suggesting that serial dosages of Lact may be a useful prognostic marker in ICU patients.
