To evaluate the effectiveness of intensive therapy for massive intraoperative blood loss in children.
A retrospective analysis of primary medical records of 39 children with massive intraoperative blood loss was performed. Patients were divided into two groups (younger 1 year (
=18) and older 1 year (
=21)). Each group was divided into two subgroups (blood loss <10% and >100% of total blood volume). We analyzed total intraoperative infusion, qualitative composition of transfusions, reinfusion of washed autologous erythrocytes and vasopressor support. In postoperative period, we assessed hemoglobin, platelets, albumin, fibrinogen, lactate, prothrombin index, duration of mechanical ventilation, severity of organ dysfunction (pSOFA score) after 1 and 3 days, ICU stay and incidence of repeated blood transfusions.
With regard to transfusion volume, we found a general pattern (3 parts of crystalloids, 2 parts of erythrocyte-containing components and 1 part of fresh frozen plasma in all groups with the exception of children older 1 year with blood loss >100% of total blood volume. The last ones had ratio 3:5:1 due to large volume of reinfusion of washed autologous erythrocytes. In all groups, target levels of hemoglobin, platelets, albumin and prothrombin index were achieved. Serum fibrinogen was slightly lower in the group with blood loss >100% of total blood volume. There was a direct relationship between blood loss and ICU stay (Spearman's test
=0.421,
<0.05), as well as duration of mechanical ventilation (Spearman's test
=0.509,
<0.05). Mean pSOFA score upon admission to intensive care unit was 3-4 points in both groups with blood loss <100% of total blood volume. In patients with blood loss >100% of total blood volume, this indicator averaged 9 points and regressed to 3-4 points over the next 72 hours.
Intraoperative intensive therapy contribute to minimal severity of postoperative organ dysfunction in children with blood loss < 100% of total blood volume and rapid regression of multiple organ failure in patients with blood loss exceeding this indicator.
