Abstract:Objective To investigat the HBL and determine its influential factors after surgery.Methods A total of 78 patients between January 2015 and January 2017 were available and included in the study.The demographic information of the patients was collected,include patients’age,gender,weight,height,fracture levels,surgery approach,coagulation,percentage of vertebral height loss and restoration.HBL was calculated according to Gross’s formula.Influential factors were further analyzed by multivariate linear regression analysis.Results The mean HBL was(303.5±59.0)mL,account for mean(53.0±10.2)% for total blood loss.Multiple and stepwise regression analysis revealed that the preoperative APPT,percentage of anterior and medium vertebral height restoration,were positively correlated with HBL.The association between HBL and the influential factors can analysis based on the regression model equation as follows:HBL= [1+e(10.81+10.11×APTT+189.52×anterior height restoration +22.01×medium height restoration)]-1.Conclusion HBL during perioperative period is much larger than what we considered and account for a substantial portion of the total blood loss.The blood loss,preoperative APPT,percentage of anterior and medium vertebral height restoration are positively correlated with HBL.HBL needs to be paid more attention to ensure patients’ safety.
