From February to July 1979, valve replacement operations with self-made bovine pericardial tissue valves were performed in 11 patients, 10 of them had rheumatic mitral incompetence and stenosis, and" 1 rheumatic aortic incompetence. All these patients had history of congestive heart failure. 5 patients were found to have coexisting tricuspid incompetence.

From February to July 1979, valve replacement operations with self-made bovine pericardial tissue valves were performed in 11 patients, 10 of them had rheumatic mitral incompetence and stenosis, and" 1 rheumatic aortic incompetence. All these patients had history of congestive heart failure. 5 patients were found to have coexisting tricuspid incompetence. The Shanghai model Ⅲ heart-lung machine with a curved tubular type of bublling oxygenerator was used, which was primed with electrolyte-balanced solution containing also bicarbonate. Peffusion rate was 50-80 ml/min/kg. The myocardium was protected by retrograde perfusion through the root of ascending aorta with 0-4℃ potas-sium cardioplegic solution, in addition, topical application of 0℃ saline and ice chips was applied to the pericardial sac. There were two (18.2%) operative deaths, one died of uncontrolable blood oozing as a result of coagulation deficiency six hours after oper-ation, the other died on the seventh postoperative day after a stormy course of low cardiac output syndrome and acute mediastinitis. Autopsy of the latter patient disclosed entangling of suture on the valve struts, causing mitral incompetence, The nine survi-vors were followed for three to nine months with remarkable clinical improvement.Symptoms disappeared nearly in all patients. These good early results were proved by auscultation, chest x-ray films, echocardiograms, and impedance cardiograms.

This paper presents the results of implantation of materials for construction of China-made pyrolytic carbon disc valve in canine thigh muscles, experiment of valve replacement in dogs and the preliminary clinical application. It was demonstrated that these materials were inert in animal tissue. The acid-resistant 00Cr17Ni14Mo2 stainless steel and dacron fabric (sewing ring) were the same as was used for caged-ball valve by us in 1965. The housing for the prosthesis was machined from a single piece of the stainless steel without welding and bending. In 40 mongrel dogs, the mitral valve was replaced with this prosthesis. The longest survival time was 28 days. According to testing data of the prosthesis in vitro and the above mentioned experiments, the prosthesis was considered justifiable for clinical use. From December 1978 to November 1979, 18 patients had undergone mitral replacement operation, resulting 16 long-term survivals and 2 early deaths unrelated to prosthesis itself. Follow-up studies of the 16 survivors 2-13 months after operation revealed reduction of cardiac size in varying degrees on X-ray films, and all had significent improvement in cardiac function. The disc was shown functioning well under echocardiographic observation. 11 patients had resumed their work. No complications related to prosthesis or to anti-coagulation therapy were observed. Based upon our clinical practice, we propose a new indirect method for measuring the diameter of mitral annulus. It is suggested that production of the valve and its clinical use may be extended.

After studying 72 clinical cases the authors believe controlled hypotension is safe and effective when used during total hip replacement operation. In addition to easy management and regulation, bleeding during the operation was obviously reduced. In comparison with the routine total hip replacement without controlled hypotension, the amount of blood transfusion used in the process of controlled hypotension was reduced by 34%.

After studying 72 clinical cases the authors believe controlled hypotension is safe and effective when used during total hip replacement operation. In addition to easy management and regulation, bleeding during the operation was obviously reduced. In comparison with the routine total hip replacement without controlled hypotension, the amount of blood transfusion used in the process of controlled hypotension was reduced by 34%. There was not any ischemic harm to the heart, brain and kidney. Use of bone cement did not lower blood pressure further. Controlled hypotension had great significance in decreasing complications during or after operation because of the clean operative field.

通过对72例全髋置换病人的研究证明,控制性低血压是安全有效的。不仅控制和调节方便,而且术中出血明显减少,与一般麻醉比较,总输血量约减少34%。对心、脑、肾等重要器官无缺血性损害,应用骨水泥对血压的变化无影响。由于手术野清楚,有利于手术操作,对减少术中和术后并发症有重要意义。
