Title: A Phase IV, Randomized, Single Center, Parallel Group Trial of Human Fibrinogen Concentrate (Haemocomplettan) in the Treatment of Dilutional Coagulopathy During Major Pediatric Surgery
Brief Summary: The purpose of this study is to compare two different thromboelastometry (ROTEM) trigger levels for administration of human fibrinogen concentrate (Haemocomplettan P) in the treatment of perioperative dilutional coagulopathy during major pediatric surgery. The study hypothesis is that administration of fibrinogen concentrate triggered by a ROTEM FibTEM MCF \< 13 mm might reduce the total amount of transfused red cell concentrate during 24 hours after start of surgery as compared to a trigger level of ROTEM FibTEM MCF \< 8 mm.


Options:
A: Inclusion Criteria:

* Males and Females
* Age 6 months to 17 years
* Scheduled for elective scoliosis surgery or major craniofacial surgery
* Written informed consent has been obtained
* Intraoperative hypofibrinogenemia according to definition of treatment groups

Exclusion Criteria:

* Preexisting congenital or acquired coagulation disorder
* Medical history of estimated increased bleeding tendency
* Ongoing coagulation therapy
* Clinical signs or diagnosis of acute thromboembolism
* Intolerance of study drug
* Participation at another clinical trial
* Pregnant or lactating women
B: Inclusion Criteria:

* adult patients
* with acute significant upper or lower gastrointestinal bleeding
* where the responsible clinician is substantially uncertain as to the appropriateness of antifibrinolytic agents in the patient

Exclusion Criteria:

* The fundamental eligibility criterion is the responsible clinician's 'uncertainty' as to whether or not to use an antifibrinolytic agent in a particular patient with upper or lower gastrointestinal bleeding.
* There are no other exclusions.
C: All legally adult women with postpartum haemorrhage following vaginal or caesarean section delivery who have a clinical diagnosis of postpartum haemorrhage. The clinical diagnosis of PPH may be based on any of the following:

* Blood loss after vaginal delivery \> 500 mL OR
* \> 1,000 mL after caesarean section OR blood loss sufficient to compromise the haemodynamic status of the woman The fundamental eligibility criterion is the responsible clinician's 'uncertainty' as to whether or not to use an antifibrinolytic agent in a particular woman with postpartum haemorrhage.
* Women for whom the responsible doctor considers there is a clear indication for antifibrinolytic therapy should not be randomised.
* Women for whom there is considered to be a clear contraindication to antifibrinolytic therapy should not be randomised.

Where the responsible clinician is substantially uncertain as to whether or not to use an antifibrinolytic, all these women are eligible for randomisation and should be considered for the trial.

There are no other pre-specified exclusion criteria.
D: Inclusion Criteria:

* Eighteen years of age or older.
* Undergoing elective complex cardiac surgery.
* Understood and willingly given written informed consent.
* Experience clinically relevant non-surgical microvascular bleeding following removal of cardiopulmonary bypass.

Exclusion Criteria:

* Positive pregnancy test, pregnancy or lactation.
* Undergoing an emergency operation.
* Proof or suspicion of a congenital or acquired coagulation disorder.
* Clopidogrel use in the 5 days preceding surgery.
* INR \>1.4 if on coumadin.
