Intraoperative blood loss in oncological spine surgery

OBJECTIVE Intraoperative blood loss in patients undergoing oncological spine surgery poses a major challenge for vulnerable patients. The goal of this study was to assess how the surgical procedure, tumor type, and anatomy, as well anesthesiological parameters, affect intraoperative use information generate short preoperative checklist surgeons anesthesiologists identify at risk increased loss. METHODS authors performed retrospective analysis 430 who underwent between 2013 2018 university medical center. Enrolled had metastatic requiring decompression neural structures and/or stabilization including biopsy using an open, percutaneous, combined dorsoventral approach. Patients vertebro- kyphoplasty or only were excluded. Statistical analyses included multiple linear regression analysis. RESULTS mean patient cohort 1176 ± 1209 ml. In total, 33.8% received red cell transfusions. statistical showed that histology indicating myeloma, operative procedure length, epidural spinal cord compression (ESCC) score, localization, BMI, strategy significantly associated with needing allogeneic Anesthesiological parameters such American Society Anesthesiologists (ASA) Physical Status classification score not Multiple demonstrated good predictive value (r = 0.437) five-item high CONCLUSIONS key factors affecting simple these can be used tumors are
