Aim: Post-operative blood transfusion is frequently required in patients undergoing Sliding Hip Screw (SHS) surgery. This is associated with transfusion related complications, increased cost and length of stay in hospital. We compared practice between two hospitals; pre-incision infiltration of local anaesthetic with adrenaline (LAAd) versus LA without adrenaline prior to wound closure, to evaluate if there was a difference in postoperative haemoglobin drop and the need for postoperative transfusion following SHS surgery.
Method: A retrospective service evaluation was performed using National Hip Fracture Database (NHFD) data in a cohort of 248 patients who underwent SHS surgery between 2017 and 2018; 110 patients had LAAd. Pre and post-operative haemoglobin, postoperative transfusion and local infiltration was recorded from the trust online patient databases. Relationships between groups was determined using z-testing on Excel.
Results: There was no significant difference in postoperative haemoglobin drop between the two cohorts (p=0.119). 32.7% of patients who had LAAd received blood transfusion in contrast with 20.3% without adrenaline.
Conclusion: Whilst surgeons using LAAd may report less bleeding from skin edges and vastus lataralis intra-operatively, and optimised regional anaesthesia, there was no significant difference in haemoglobin drop between the two cohorts. A difference in threshold for transfusion was identified between the
