O3064 BLOOD SALVAGE DURING PELVIC TRIPLE OSTEOTOMY UNDER ADRENALIN AUGMENTED HYPOTENSIVE EPIDURAL ANAESTHESIA

Abstract

Aims: Evaluation of the potential of blood salvage in osteotomy of the pelvis after T…NNIS, using a special anaesthetic technique (Adrenalin Augmented Hypotensive Epidural Anaesthesia, AAHEA). Methods: From 1997 to 2002 thirtynine patients had surgery. 25 patients (4 men, 21 women; average age 33 yrs) had AAHEA and 14 (3 men, 11 women; average age 32 yrs) had standard anaesthesia. Autologous blood donation, intra-operative and postoperative cell saving was evaluated. The haemoglobine proþle, evidence of haematoma and the time needed for the operation were noted. In both groups 2 patients had additional surgery with intertro-chanteric osteotomy. Results: In this series haemoglobine was statistically signiþcant higher with AAHEA (p< 0,05) after a period of 7–10 days, and lower total usage of blood donation (p< 0,05) was evident. Amount of blood, collected with the cell saver intraoperatively: In the group with AAHEA 179 ml (± 155) versus standard-anaesthesia 935 ml (± 749); autologous blood donation: AAHEA-group 64% versus standard-group 77%. Conclusions: AAHEA is able to lower perioperative blood loss in major orthopaedic bone and joint surgery. This method leads to a remarkable reduction of the intra-operative blood loss and perioperative need of blood donation, autologous and homologous, further to a minimized risk of associated complications and lower costs.
