title: Systematic review of the efficacy and safety of fibrinogen concentrate substitution in adults.
abstract: BACKGROUND
  A sufficient plasma level of fibrinogen is critical for the formation of a fibrin clot and haemostasis in both the perioperative setting and in massive haemorrhage. We assessed the efficacy and safety of fibrinogen concentrate substitution in the perioperative setting and in massive haemorrhage.
  
  
  METHODS
  We conducted a systematic literature search for studies conducted on humans and published in either English or German in several databases from 1985 to 2010. In addition, we screened several web sites for assessments on fibrinogen concentrate substitution and conducted a hand search using Scopus. In terms of efficacy, we included all prospective, controlled studies. Concerning safety, we included all prospective studies.
  
  
  RESULTS
  We identified two randomised controlled trials and two non-randomised controlled studies, which included a total of 74 patients. The studies indicate that the administration of fibrinogen concentrate is associated with improved clot firmness and reduction in the substitution of other blood products such as red blood cells, fresh frozen plasma and platelet concentrates, as well as decreased post-operative bleeding and drainage volume. In addition, fibrinogen concentrate administration has been reported to be safe with regard to thrombosis and thromboembolic complications, as well as mortality. However, the studies identified were of poor quality.
  
  
  CONCLUSIONS
  In conclusion, the results of the available controlled trials suggest that the administration of fibrinogen concentrate was effective and safe. However, because all studies identified were of inadequate quality, these findings need to be confirmed by randomised controlled trials of sufficient size and long-term follow-up.
