We recommend the use of a structured patient interview or
questionnaire before surgery or invasive procedures, which
considers clinical and family bleeding history and detailed
information on patients’ medication
Assessment of potential
bleeding risk
1C
We recommend the use of standardised questionnaires on
bleeding and drug history as preferable to the routine use of
conventional coagulation screening tests such as aPTT, PT and
platelet count in elective surgery

We recommend that aspirin therapy should continue perioperatively in most surgical settings, especially in cardiac surgery
1C
Clopidogrel increases perioperative bleeding. In cases of
Antiplatelet therapy
Clopidogrel increases perioperative bleeding. In cases of increased bleeding risk, we recommend that it should be withdrawn for no more than 5 days.

We recommend postponement of elective surgery followingcoronary stenting (at least 6 to 12 weeks for bare metal stent and one year for drug-eluting stents).

Antiplatelet therapy
We recommend that a multidisciplinary team meeting should decide on the perioperative use of antiplatelet agents in urgent and semi-urgent surgery.

We recommend against the use central venous pressure and
pulmonary artery occlusion pressure as the only variables to guide
fluid therapy and to optimise preload during severe bleeding;
dynamic assessment of fluid responsiveness and non-invasive

We recommend a target haemoglobin concentration
of 7–9 g dl–1 during active bleeding
1C
Red blood cells
1C
We recommend that RBCs up to 42 days of age be transfused
according to the first-in-first-out method in the blood services

We suggest that transfusion of platelet concentrates maybe considered if platelet count is <50 000–100 000 ml–1 .
2C
Platelets
For intra- or postoperative bleeding clearly related to aspirin, we suggest that platelet transfusion be considered (dose: 0.7x1011
