RÉSUMÉ
Objective To systematically analyze the risk factors of venous thromboembolism (VTE) occurrenced in intensive care unit(ICU).Methods The literatures on risk factors for ICU-acquired VTE were retrieved from PubMed,Cochrane Library,Embase,ScienceDirect,CNKI,WanFang,VIP and CBM Databases.Then the data was extraction and quality assessment was performed.The RevMan 5.3 software was used for conducting the Meta-analysis.Results Fifteen articles were included,involving 939 VTE cases.The meta analysis results of different factors were the renal insufficiency(OR =14.60),deep v ein thrombosin(DVT)/pulmonary embolism (PE) history(OR=8.23),rencent surgery history(OR =6.75),age＞ 60 years old(OR =4.84),shock(OR =4.36),malignant tumors (OR=2.76),central venous catheter(OR=2.54),heart function grade＞3(OR=2.27),mechanical ventilation(OR=1.57),D-dimer(WMD=423.99),APACHE Ⅱ score(WMD=4.25).Conclusion The risk factors of developing VTE in ICU are renal insufficiency,DVT/PE history,recent surgery history,age≥60 years old,shock,malignant tumors,central venous catheter,heart function grade＞3,mechanical ventilation,D-dimer and high APACHE Ⅱ score.
