Surgical (non-orthopaedic) patients

 

Note: Surgical patients at St John’s site are risk assessed according to the Caprini Score.

 

Low risk Prophylaxis
Minor surgery including gynae (less than 30 min), no other risk factors (as outlined in Table A, page 7). Mobilise early
Moderate risk Prophylaxis
Minor surgery with any risk factor in Table A, page 7, or Major surgery with no risk factors (as outlined in Table A, page 7). Dalteparin 2500 units may be administered subcutaneously 1-2 hours before the surgical procedure (CHECK YOUR LOCAL POLICY - this should not be given if spinal or epidural anaesthesia is planned - see Table J), and thereafter dalteparin 2500 units subcutaneously each morning until patient is mobilised, in general 5-7 days or longer.
High risk Prophylaxis
Major pelvic or abdominal surgery with any risk factor (Table A, page 7). Dalteparin 2500 units may be administered subcutaneously 1-2 hours before the surgical procedure (CHECK YOUR LOCAL POLICY - this should not be given if spinal or epidural anaesthesia is planned - see Table J) and dalteparin 2500 units subcutaneously 8-12 hours later. On the following days, dalteparin 5000 units subcutaneously each morning. If dalteparin is not given pre-operatively, dalteparin 2500 units should be given as soon as possible (4-6 hours) post operatively followed by 5000 units each evening. As an alternative, dalteparin 5000 units is administered subcutaneously the evening before (at least 12 hours) the surgical procedure and 5000 units subcutaneously the following evenings. Treatment is continued until the patient is mobilised, in general 5-7 days or longer.
