Abstract：Objective To examine the amount of hidden blood loss and determine its relative influential factors after percutaneous kyphoplasty.Methods We retrospectively analyzed 124patients of thoracolumbar vertebral compression fracturetreated withPKP from June 2012 to June2016 inLiaoyang CentralHospital.The amount of hidden blood loss was Calculated.The influential factors on hidden blood loss analyzed included gender,age,body mass index,the degree of vertebral compression,the degree of vertebral body restoration,number of treated fracture levels,bone mineral density,bone cement leakage and internal diseases (diabetes,hypertension).Results The mean amount of hidden blood loss was (304±171)mL.The degree of vertebral compression,the degree of vertebral body restoration,number of treated fracture levels,bone mineral density,bone cement leakage were significantly associated with the amount of hidden blood loss (P<0.05).Gender,age,body mass index,diabetes,hypertension were not significantly associated with the amount of hidden blood loss(P>0.05).Conclusion Hidden blood loss cannot be ignored,especially for multiple injuries patients and the elderly with poor physical condition.Having a correct understanding of hidden blood loss can help ensure patients'' safety in perioperative period.
