[Influence of albumin as a resuscitation fluid on the prognosis of patients with sepsis: a Meta-analysis].

OBJECTIVE To compare the effect of albumin as a resuscitation fluid with other fluids in lowering the mortality of patients with sepsis. METHODS By searching MEDLINE, Embase, Cochrane Central Registration of Controlled Trials databases, the metaRegister of Controlled Trials, the Medical Editors Trial Amnesty Register, and retrieval of the randomized controlled trial (RCT) literature to compare the result of resuscitation using albumin-containing fluid and other fluids. The study population included adult patients who were diagnosed to have sepsis, and the patients with sepsis who were studied as subgroup. The RevMan 5.0 software was used for Meta-analysis, and the main outcome was the mortality of the hospitalized patients. RESULTS In the 14 RCTs, 1729 patients received the albumin-containing fluid resuscitation or resuscitation with other fluids. It was found that the patients with sepsis were the only research objects in five studies, and in other nine studies patients with sepsis were studied as subgroup. P = 0.98, I (2)=0%, i.e. no heterogenicity, and the fixed effect model was used for combining results. There was no evident difference between the group of patients with sepsis resuscitated by albumin-containing fluids and other fluids [odds ratio (OR) was 0.87, 95% confidence interval (95%CI) 0.71-1.07, P = 0.18]. The pooled OR of resuscitation using high concentration albumin solution (20%) was 1.11, 95%CI 0.71-1.73, P = 0.65, the pooled OR of resuscitation using low concentration albumin solution (4%, 5%) was 0.82, 95%CI 0.65-1.03, P = 0.09. Resuscitation with different concentration of albumin-containing fluids was identical with the whole research results. After rejecting six articles of Boldt and other authors, and also saline versus albumin fluid evaluation (SAFE) study, the sensitivity analysis of the study was performed in order to check whether the data produced decisive significance to the whole research results or not. The whole results did not change after their rejection(Boldt studies were rejected:OR 0.82, 95%CI 0.65-1.02, P = 0.08; SAFE study was rejected: OR 1.05, 95%CI 0.71-1.55, P = 0.82). Therefore the analysis results were satisfactory. CONCLUSION The Meta-analysis shows that by using albumin-containing fluids for resuscitation can not lower the mortality of sepsis as compared with other fluids.
