Introduction of a ROTEM-assisted strategy improves patient blood management in children undergoing open craniosynostosis repair

Abstract

Purpose The surgical correction of craniosynostosis by open cranial vault reconstruction (OCVR) is often associated with significant blood loss and perioperative blood transfusion demand. Because of transfusion risks, several attempts have been made to eliminate the need for perioperative homologous blood transfusion with the implementation of goal-directed transfusion protocols. The aim of this study was to determine whether the introduction of a rotational thromboelastometry (ROTEM)–assisted patient blood management strategy would decrease the intraoperative blood transfusion and blood loss levels. Methods Patients younger than 2 years of age who were diagnosed with nonsyndromic single suture synostosis and underwent primary OCVR were investigated in this retrospectively designed cohort study. The children were equally divided into 2 study groups according to the availability of the ROTEM-assisted protocol. The control group had surgery before introduction of the new protocol, whereas the study group was operated on subsequently. Demographic, blood loss, and transfusion data of the preprotocol cohort were compared with those of the postprotocol cohort. Results In total, 100 children, separated in 2 groups (50 patients each), were analyzed. The mean age at the time of surgery was 8.5 months in the pre-ROTEM-assisted protocol group, and 8.7 months in the postimplementation group. The estimated blood volume loss dropped from 60.8 mL/kg to 49.6 mL/kg after initiation of the current strategy. The intraoperative packed red blood cell (PRBC) transfusion volume decreased from 32.6 mL/kg to 17.1 mL/kg. Administration of PRBCs in the postoperative period also was reduced, compared with the period before implementation of the ROTEM-assisted regimen, from 21.8 mL/kg to 15.9 mL/kg. The average length of hospital stay was reduced from 5.4 days to 4.7 days after use of the ROTEM-assisted protocol. Conclusions As indicated by our results, the use of a ROTEM-assisted protocol is associated with considerable reduction in blood volume loss and perioperative allogeneic transfusion requirements in the surgical management of craniosynostosis with OCVR.
