Background and Aims: Myomectomy is associated with perioperative bleeding. The aim of the study is to evaluate the effect of intramyometrial vasopressin on blood loss and the associated cardiovascular complications during myomectomy. Methods: The study included 194 patients classified into two groups- 1) Vasopressin group: the vasopressin was diluted as 0.1 unit/ml and 15 ml was injected by the surgeon in the plane between the myometrium and the myoma. 2) Control group: The patients received an equal amount of normal saline. The monitored parameters included the amount of blood loss, required blood transfusion, heart rate, mean arterial blood pressure, the incidence of hypertension, hypotension, bradycardia, tachycardia, electrocardiogram (ECG) changes and the blood troponin I level. Results: The heart rate decreased significantly in both groups, but the decrease was lower with vasopressin than the control group through the time points T3 to T5 (P < 0.05) The mean arterial blood pressure increased significantly in both groups, but the increase was higher with vasopressin than the control group through T3 to T5 (P < 0.05). The amount of blood loss decreased significantly with vasopressin than the control groups (P = 0.001). The number of transfused packed red blood cells was lower with vasopressin than the control group (P = 0.001). The incidence of hypertension, bradycardia and atrial extrasystole was higher with vasopressin than the control group (P = 0.005, P = 0.012, P = 0.033, respectively). Conclusion: Intramyometrial vasopressin decreases blood loss and blood transfusion, but it is associated with cardiovascular complications that may be serious as reported in other studies. Therefore, anaesthesiologists and gynaecologists must follow the precautions to avoid and minimise the incidence of complications with intramyometrial vasopressin.
