Prognostic value of B-type natriuretic peptide (BNP) and its potential role in guiding fluid therapy in critically ill septic patients

Table 2 Multivariate Logistic regression analysis of variables associated with mortality

Variables	Odds ratio	95% confidence interval	P value
BNP0 (with each 100 pg/ml increase)	2.14	1.07-4.27	0.03
Age	1.05	0.97-1.14	0.20
APACHEII	1.97	1.22-3.19	0.006
Cardiac output	0.25	0.06-1.01	0.05
Day 2 fluid balance (with each 100 ml increase)	1.50	1.10-2.04	0.01
Extravascular lung water	0.83	0.66-1.05	0.13

BNP0 represents the B-type natriuretic peptide measured on ICU entry.
Abbreviations: APACHEII, Acute Physiology and Chronic Health Evaluation; CVP, central venous pressure.
