We have experienced 20 cases of anesthesia for Total Hip Replacement(Charnley´s Low Friction Arthroplasty), which had been done under the Filtered Air Flow System for the prevention of wound contamination due to long term exposure.
Preoperative diagnosis was, 7 cases of Hip Joint Tuberculosis, 6 cases of Femur Neck Fracture, 5 cases, of Osteoarthritis of Hip Joint, and 2 cases, of Avascular Necrosis.
Average blood loss has 1500 ml for one side operation, and 2400 ml for bilateral one. In 12 cases, hypotensive response was occurred during the application of Acrylic bone cement to the medullary canal of femur, however in 4 cases, hypotensive responses was more prominentafter the application of Acrylic bone cement to the Acetabulum fossa and the rest of cases were no changes in blood pressure and pulse rate whatsoever.
In two cases, hypotensive range was over 30% (in compare with preoperative one), but recovery was soon after administration of Effortil corticosteroids, volume expanders etc. There was no mortality.
