چکیده

background:  patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (bcis) which is a leading cause of intraoperative complications. the purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   methods:  cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. all patients were catheterized with a radial artery catheter to assess mean arterial pressure (map) and arterial blood gas (abg) in these time points: just before cementation, just after cementation (0th), 5 min (5th) and 10 min (10th ) after cementation, and at the end of surgery (end). also, systolic and diastolic blood pressure (sbp & dbp), heart rate and any arrhythmia or cardiac arrest was evaluated.  results:  seventy-two patients (33 females, 39 males; mean age: 66.8±7 years) were evaluated. all parameters changed during cementation with a significant drop in map, sbp, and dbp immediately after cementation and ph and base excess decreased significantly (p<0.001) with no changes in o2 saturation. mean heart rate rose until the 5th and then decreased dramatically with no bradycardia presentation. during cementation, 12 patients showed arrhythmia, but no cardiac-arrest was observed.   conclusions:  under strict observation of a anesthesiology care team, hemiarthroplasty can be a safe method for femoral neck fracture in elderly osteoporotic patients without severe cardiopulmonary compromise.

Acute Acalculous Cholecystitis following The Cemented Hemiarthroplasty in an Elderly Hip Fracture Patient: Case Report

Postoperative acute acalculous cholecystitis (AAC) was a well-known abdominal complication of general surgery [1-3], but in orthopedic surgery only sporadic case reports could be retrieved [4-7]. Postoperative AAC was unrelated to the biliary tract, which was characterized by gallbladder inflammation without evidence of calculi or sludge [8]. Once postoperative AAC occurs, the disease progresse...
