Heparin for treatment of sepsis: a systemic review / 中华危重病急救医学

ABSTRACT

Objective To systemically review the efficacy and safety of heparin for treatment of sepsis.Methods Database search of IM/MEDLINE,Cochrane Library,SCIE,CBM,CNKI,VIP Data,WanFang Data (from January 2000 to June 2012) was conducted.The quality of included randomized controlled trials (RCTs) about heparin for treatment of sepsis was assessed,and relevant data were extracted according to the inclusion and exclusion criteria.Then meta analysis was performed using RevMan 5.1.Results 17 trials with 1 167 participants were included.The results of meta-analysis showedcompared with the control group,heparin significantly decreased 28-day mortality in patients with sepsis [odds ratio (OR) =0.59,95％ confidence interval (95％CI) 0.45-0.77,P=0.0001] ; heparin did not deteriorate coagulation disorders,but corrected sepsis-induced platelet (PLT) count reduction [mean difference (MD) =13.94,95％ CI 10.15 to 17.72,P＜0.000 01],while it had no significant effect on the activated partial thromboplastin time (APTT) and prothrombin time (PT,APTTMD=-3.18,95％CI-6.88 to 0.53,P=0.09; PTMD=-0.68,95％ CI-1.48 to 0.12,P=0.09).There was no significant difference between the two groups in the incidence of bleeding either.Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score of heparin group was significantly lower than that of the control group (MD=-2.58,95％CI-3.29 to-1.87,P＜0.000 01),and the incidence of multiple organ dysfunction syndrome (MODS) was significantly lower than that of the control group (OR=0.32,95％CI 0.17 to 0.61,P=0.000 6).In addition,heparin could shorten intensive care unit (ICU) stay (MD=-4.43,95％CI-6.79 to-2.07,P=0.000 2),whereas it showed no significant effect on the total length of hospital stay.Conclusions Heparin can ameliorate sepsis,and has high degree of safety and lower hospital expense.Due to limitation of the quality of included studies,larger sample and well-designed RCTs are needed to further support this conclusion.
