Hemodynamic changes and related factors in bone cement implantation syndrome in knee arthroplasty candidates

Introduction: Considering the importance of the anesthesia and surgery team’s awareness of possible hemodynamic changes when using bone cement and preventing its risks, it is very important to know about this issue. Objectives: This study aimed to identify and prevent the risks of possible hemodynamic changes and related factors when using bone cement in knee arthroplasty candidates. Patient and Methods: This descriptive-analytical study of 63 knee arthroplasty candidates in Imam Reza and Shohada hospitals (affiliated with the Tabriz university of medical sciences) was conducted in 2020. The hemodynamic status (heart rate, blood pressure, and arterial oxygen saturation (SaO2 )) of all patients was recorded and changes were calculated three minutes before, during, and three minutes after using bone cement. Results: The increase in diastolic (P=0.221) and systolic (P=0.195) blood pressure and heart rate (P=0.125) over time (before and after using bone cement) was statistically insignificant. However, the arterial oxygen saturation of patients remained constant (P=0.999). Conclusion: The results showed that using bone cement causes minor changes in (systolic and diastolic) blood pressure and heart rate.
