Abstract
To assess the efficacy of intramyometrial vasopressin for minimising bleeding and its sequelae at myomectomy, a randomised placebo controlled trial was conducted. At the University Hospital of the West Indies, Kingston, Jamaica, 20 women with symptomatic uterine fibroids scheduled for myomectomy, who satisfied entry criteria, were selected, Ten were randomised to the vasopressin group and 10 to the control group. Myomectomy was performed after the intramyometrial injection of either 20 units vasopressin diluted to 20 ml in normal saline, or placebo (20 ml normal saline). The efficacy of vasopressin was measured by comparing pre- and post-operative haemoglobin levels and haematocrit, changes in intra-operative pulse and blood pressure, measured blood loss, need for blood transfusion, and post-operative febrile morbidity in the treatment and control groups. The use of vasopressin resulted in median blood loss of 225 ml (range150-400ml) compared with 675 ml (range 500-800ml) in the placebo group (p<0.001). The vasopressin group had a correspondingly lower fall in haemoglobin level (median 1.7g/dl vs 5.3g/dl, p<0.001) and haematocrit (median 5% vs 13%, p<0.001) compared with the controls. Fifty percent of the placebo group had blood transfusions compared with none in the vasopressin group. There were no significant differences between the groups in intra-operative pulse and blood pressure, or in post-operative white blood cell counts or temperature. Vasopressin is effective in preventing blood loss and reducing the need for blood transfusion during myomectomy.....
