The objective is to analyse peri-operative blood loss (BL) and hidden blood loss (HBL) rates in spinal deformity complex cases surgery, with a focus on the strategies to prevent major bleeding.We retrospectively analysed surgical and anaesthesiologic data of patients who had been operated for adolescent idiopathic scoliosis (AIS) or adult spinal deformities (ASD) with a minimum of five levels fused. A statistical comparison among AIS, ASD without a pedicle subtraction osteotomy (PSO) (ASD-PSO( -)) and ASD with PSO (ASD-PSO( +)) procedures was performed with a view to identifying patient- and/or surgical-related factors affecting peri-operative BL and HBL.One-hundred patients were included with a mean 9.9 ± 2.8 fused vertebrae and a mean 264.2 ± 68.3 minutes operative time (OT) (28.3 ± 9 min per level). The mean perioperative BL was 641.2 ± 313.8 ml (68.9 ± 39.5 ml per level) and the mean HBL was 556.6 ± 381.8 ml (60.6 ± 42.8 ml per level), with the latter accounting for 51.5% of the estimated blood loss (EBL). On multivariate regression analysis, a longer OT (p 0.05; OR 3.38) and performing a PSO (p 0.05; OR 3.37) were related to higher peri-operative BL, while older age (p 0.05; OR 2.48) and higher BMI (p 0.05; OR 2.15) were associated to a more significant post-operative HBL.With the correct use of modern technologies and patient management, BL in major spinal deformity surgery can be dramatically reduced. Nevertheless, it should be kept in mind that 50% of patients estimated losses are hidden and not directly controllable. Knowing the per-level BL allows anticipating global losses and, possibly, the need of allogenic transfusions. |
