AbstractAmicar may affect estimated blood loss (EBL) and blood transfusion in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF) with pedicle screws and Ponte osteotomies. We performed a retrospective analysis of a prospectively collected, single-center database of 33 patients with main thoracic AIS treated with greater than 80% pedicle screws. Patients were divided into two groups based on whether they received Amicar (Yes), or did not receive any antifibrinolytics and Ponte osteotomies (No). Demographic, radiographic, and intraoperative data were compared between the two groups. Seventeen patients were treated with Amicar (Yes) (10 of whom had Ponte osteotomies) and 16 patients had neither antifibrinolytics nor Ponte osteotomies (No). The two groups had similar preoperative main Cobb angles, major curve flexibility, and gender. Despite longer operating times and a majority of patients receiving Ponte osteotomies, the Amicar group had a significantly lower EBL and homologous blood transfusion rate. Autologous transfusion volume was less in the Amicar group and trended toward significance. There were no differences in mean arterial pressure during surgery. There were no complications in either group. Amicar reduces EBL and homologous transfusion requirements in patients with main thoracic AIS undergoing PSF with pedicle screws and Ponte osteotomies.
