At present patients who require shoulder hemiarthroplasty in our unit routinely have two units of blood cross matched pre-operatively. Our observation was that blood transfusion rarely required after open shoulder surgery. We therefore decided to look at the crossmatch-transfusion ratio for the following procedures in our department; elective shoulder hemiarthroplasty, reverse total shoulder replacement, open rotator cuff repair, shoulder hemi-arthroplasty for trauma, open reduction and internal fixation of proximal humeral fractures.

We undertook a retrospective review of all such patients during the period of 2002 to 2005. All trauma and elective surgery included. Hospital notes were analysed to include age, sex, pre operative haemoglobin level, blood transfusion intra-operatively and post-operatively.

A total of 211 patients were included in the study. There were 63 elective procedures and 148 trauma procedures during that period. No patient required intra-operative or post operative transfusion. Three patients who required transfusions post operatively, due to other associated injury (liver laceration x1, spleen injuries x 2) were excluded from the study. Crossmatch-transfuison ratio was > 2.

There should be a clear equation between cross-match and its use, intra-operatively and post operatively. This study highlighted unnecessary cross-matching for shoulder operations in our unit which puts extra pressure on the laboratory staff, the blood bank and also has financial implications. We recommend, Standardised approach for pre-operative cross match practise, pre-operative group and screen to detect atypical antibodies and efficient hospital pathology services, to provide blood for transfusion within specified time, for atypical antibody negative blood, should it require.
