Epidemiology of Severe Peroperative Bleeding During Scheduled Surgery
Epidemiology of Severe Peroperative Bleeding During Scheduled Surgery
Peroperative bleeding has been studied in specific populations exposed to bleeding (i.e.
 cardiac surgery, orthopedic surgery). Epidemiology of peroperative bleeding and transfusion
 remain poorly studied in the whole cohort of patients scheduled for surgery remain unknown.
 The investigators conducted a prospective study in order to examine the incidence, and risk
 factors associated with peroperative bleeding and transfusion.
This was a prospective observational including all consecutive patients scheduled for surgery
 during a 3 month period.

 Exclusion criteria were : emergency, cardiac surgery, and pediatric surgery. Patients
 received an oral information and informed consent was search for all of them.

 Throughout the study period (3 months) data were prospectively recorded by members of a
 specific research team not involved in the care of patients. Preoperative, peroperative and
 immediate postoperative data (post anesthesia care unit) were collected.

 Unanticipated bleeding was defined as either transfusion above the pre ordered packed red
 blood cells or hemoglobin concentration < 8 g/dL.
Inclusion Criteria:

 -  Patient scheduled for non cardiac and non emergency surgery

 Exclusion Criteria:

 -  Cardiac surgery

 -  Emergency surgery
