Abstract:
Objective To assess the relationship between lactate clearance and prognosis of patients with multiple organ dysfunction syndrome following resuscitation.Methods Data of 42 eligible patients with multiple organ dysfunction syndrome after resuscitation admitted from January 2009 to December 2011 were collected for retrospective analysis.The patients included were adult patients who survived more 24 hours after CPR for cardiac arrest with subsequent multi-organ failure.Exclusion criteria were traumatic heart arrest and the end-stage diseases.All the patients were divided into survival group and death group on the 3rd day and the 7th day after restoration of spontaneous circulation.The differences in the age,gender,mean arterial pressure,oxygenation index (PaO2/FiO2),APACHE Ⅱ score,white blood cell count (WBC),initial lactate level and 6h lactate clearance rate between the two groups were compared by using the Mann-Whitney U-tests and logistic regression analysis.Results Of 42 patients,the mean age was (59.57±14.68) years and mean APACHE Ⅱ score was (26.79 ±7.77),and 23 (54.8％) patients survived until the 3rd day and 14 (33.3％) patients survived to the 7th day after restoration of spontaneous circulation (ROSC).Univariate analysis showed that APACHE Ⅱ score in death group was significantly higher and 6 h lactate clearance was significantly lower than those in survival group (P ＜ 0.05) on the 3rd day and the 7th day after ROSC,and other biomarkers were not significantly different between the two groups.The results from logistic regression analysis showed that there were statistically significant difference in APACHE Ⅱ score (RR =2.143,P =0.028) and 6-h lactate clearance (RR =0.887,P =0.040) between survival group and death group on the 7th day after ROSC,although no significant differences in APACHE Ⅱ score and 6 h lactate clearance were found between the two groups on the 3rd day after ROSC.Conlusions Post-cardiac arrest patients with low lactate clearance in the early stage after ROSC have a poor prognosis.Lactate clearance may be an independent predictor of mortality in post-cardiac arrest patients in the recovery phase.
