BLOOD PRESSURE CHANGE DURING TOTAL HIP ARTHROPLASTY USING INTERFACE BIOACTIVE BONE CEMENT TECHNIQUE

BackgroundCement implantation syndrome characterized by hypotension, hypoxemia, cardiac arrhythmia or arrest has been reported in the literature. The purpose of the present study was to monitor blood pressure soon after cementing.MethodsThe present study includes 178 cases 204 joints of primary THA with an average age at operation of 64.5 years old (ranging 35 to 89). Under general anesthesia, both components were cemented using antero-lateral approach. Systolic arterial blood pressure during cementing acetabular and femoral components was monitored until 5 minutes with 1 minute interval. The maximum regulation ratio (MRR) was calculated as (maximum change blood pressure – blood pressure before cement insertion) divided by blood pressure before cement insertion.ResultsNo major complications such as cardiac arrest were observed. In most of the cases, blood pressure increased until 4 minutes for the acetabular side and 2 minutes for the femoral side, and then returned to the blood pressure before cement ins...
