Cardiac Arrest Following Methylmethacrylate Bone Cement during Total Hip Replacement: A case report / 대한구급학회지

ABSTRACT

Cardiovascular reactions to acrylic bone cement in patients with total hip replacement are a common complication. Hypotension and arrhythmias are the most frequently observed symptoms. Elderly patients with fractures of the femoral neck constitute a special risk group. In some patients these reactions will be fatal. The mechanisms suggested to explain these reactions are embolism of air, polymer or fat, reaction to the heat, and toxic or vasodilating effects of the acrylic monomer. It may be that potentially lethal complications only occur if two or more of the predisposing factors (hypovolemia, myocardial insufficiency, arrhythmia, embolism, histamine release) are present simultaneously. We have experienced a case of complication following bone cement insertion under spinal anesthesia. This female patient was 91 years old with old myocardial infarction on EKG.
