Successful management of severe manifestation bone cemented implantation syndrome during hemiarthroplasty surgery in patient with multiple comorbidities: A case report

INTRODUCTIONBone Cement Implantation Syndrome (BCIS) is a lethal condition with complex physiological changes after the insertion of Methyl Methacrylate (MMA) cement during intraoperative arthroplasty. Despite the etiology and the pathophysiology of BCIS has not been fully understood, several mechanisms have been discovered. Some clinical manifestations of BCIS are hypotension, hypoxemia, a decrease of consciousness, arrhythmia, pulmonary hypertension, and cardiac arrest. PRESENTATION OF CASEA 67 years old woman underwent cemented hemiarthroplasty operation due to intertrochanteric fracture in her right femur. The hemodynamic was stable before and during operation, but suddenly the patient went into cardiac arrest as the cement inserted. Immediate resuscitation was performed successfully and stable hemodynamic was achieved. DISCUSSIONSeveral risk factors including underlying cardiovascular disease, advanced age, osteoporosis (enlarged porous cavities increase the risk of emboli generation), fracture type, metastatic bone disease, femoral canal diameter of more than 21 mm, previously non-instrumented femoral canal, and patent foramen ovale (paradoxical embolus). Some studies have shown usage of H1 and H2 antagonists, methylprednisolone, inotropes, vasopressor, and some alterations in surgical technique, can prevent the progression of the BCIS. Communication between the orthopaedic surgeon and anesthesiologist and high-quality cardiopulmonary resuscitation (CPR) will become a good basis in treating BCIS. CONCLUSIONPreoperative optimization by increasing oxygen inspiration concentration, usage of inotropes and vasopressor, and avoiding intravascular volume depletion during operation is essential in cemented arthroplasty procedure. Both orthopaedic surgeon and anesthesiologist should recognize the clinical presentation of BCIS and well-prepared for the management of BCIS including any supportive measures.
