Abstract

Little is known about how bone cement and American Society of Anesthesiologists (ASA) classification influence the cardiovascular system in elderly patients with femoral-neck fractures treated with cemented hemiarthroplasty. Therefore, we performed a case-control study to investigate these questions and compared the following:≥ASA III with≤ASA II patients who underwent cemented hemiarthroplasty; and cemented with cementless hemiarthroplasty in≥ASA III patients. ASA classification influences the cardiovascular system during cemented hemiarthroplasty and bone cement influences intraoperative blood pressure [IBP] in patients rated≥ASA III. This multicenter, prospective study included patients with acute displaced femoral-neck fractures. Baseline data, medical history, anesthesia, FiO2, vasopressor use, femoral component, IBP, SpO2, and complications were evaluated. Of 200 patients, 100 were cemented (mean age, 77±10 years), and 100 were cementless (mean age, 78±9 years). Cemented hemiarthroplasty employed a third-generation technique (plugging, irrigating, drying and filling the canal with cement under pressurization). Systolic blood pressure (SBP) decreased significantly during cementing, versus pre-rasping in≤ASA II patients (fr...Continue Reading
