Preoperative autologous blood deposition in support of gynaecological repair procedures

Autologous blood transfusion was evaluated in gynaecological repair procedures including abdominal/ vaginal hysterectomy with vaginal repair, post-hysterectomy vaginal suspension and fixation, uni/bilateral salpingo-oophorectomy with vaginal colpopexy and sling procedures. A total of 247 autologous units were collected from 95 patients at the regional blood centre with 1-3 units (mean 2-6 units) deposition from each patient. One hundred and ninety of all collected units were transfused (collection/transfusion ratio = 1.3). Of these patients, 86 (90.5%) received autologous blood; 12 (13%) being transfused with 1 unit, 44 (46%) with 2 units and 30 (32%) with 3 units. Two of these patients received additional homologous blood. The average preoperative haemoglobin level was 119 g L-1 and average post-operative haemoglobin level was 105 gL-1. The post-operative Hb level was used as a retrospective indicator for the requirement for blood transfusion. The results show that overall 75% of patients had post-operative haemoglobin levels < or = 110 and 33% of patients with Hb levels < 100, respectively. These results suggest that preoperative autologous blood deposition may be appropriate in the patients undergoing reconstructive gynaecological repair procedures since there was a high rate of usage of autologous blood and low post-operative haemoglobin in a significant proportion of patients.
