TP9.2.24Is preoperative ABO blood typing required in emergency appendicectomies?

Abstract Aims Intra-operative bleeding is very rarely a complication of laparoscopic appendicectomy. Despite this, it often mandatory for any patient undergoing an emergency appendicectomy to have pre-operative ABO blood type sampling. This could be unnecessary expense and may lead patients being delayed theatre. The aim this study was see how many who underwent required transfusion intra-operatively or within 30 days their operation. Methods Data were collected retrospectively all ages suspected appendicitis at single centre from March 2018 May 2020. primary outcome measure intra-operative post-operative up until after the Results Over 26 months, 698 appendicectomies performed. Preoperative typing performed in 95% (n = 663) patients. Collectively, 1,305 samples obtained combined total cost £13,703 hospital. None intra- post-operatively. Pre-operative only three patients, due chronic anaemia. 21 (3%) going theatre whilst awaiting two valid results. Conclusions Emergency experience complications associated with requiring transfusion. Clinical guidelines should reflect by avoiding recommendation such tests appendicectomies, reducing delays surgery resulting more efficient allocation financial staff resources.
