Experimentally on 116 dogs it has been found that intravascular shunts of a big diameter or those controlled by means of extracorporal shunts ensure stable hemodynamic indices, approximately the initial ones. The isolated hypothermal perfusion protects, in its turn, the liver from an ischemic trauma and prolongs the safety period of the liver blood flow break to 40 minutes and more.

Some employers spend half their health benefits dollars on outpatient care. Utilization of ambulatory services is up, costs-per-case are escalating fast--with some procedures demonstrably costing 85%-95% of inpatient charges--and providers' profits are increasing. Executives of the Health Data Institute and The Associated Group describe a multi-pronged approached to managing the burgeoning costs of a health care delivery alternative that was supposed to save employers money.
Health care delivery in Belgium is based on a compulsory insurance system, installed and controlled by the government since 1945 for employees; in 1963 the system was expanded to include self-employed citizens. Mutual benefit organizations act as insurance carriers for all patients, whether cared for in the office or hospital. The cost of state-financed medical care has grown to such an extent during the last few decades that cost-sharing in ambulatory practice is being extended to in-clinic services. The free choice of practitioners as well as free access to medical and specialist education have always been keystones of the Belgian medical care system. A well regulated scheme of surgical training combined with strict rules imposed on instructors, hospitals, and trainees guarantee high quality and state-controlled surgical education. Developments in the Belgian political landscape may considerably affect health care delivery and surgical education. A constant rise in the number of medical practitioners and the sociopolitical discrepancies between the Flemish and French speaking parts of the federalized kingdom have paralleled burgeoning medical health care costs and have induced rationalization and possibly federalization of health care delivery as well as ongoing debates concerning the limitation of medical and surgical practitioners.

During 1993, more than 6,000 patients covered by MetLife group health contracts were hospitalized for the surgical or medical treatment of back pain. Among the 3,480 patients aged 21 to 64 with surgically treated back problems, the total charge averaged $13,990, with just over half of this total attributed to the hospital charges. The average length of hospital stay was 3.1 days for these patients. Of the 2,529 nonsurgically treated patients with back problems aged 21 to 64, the average charge totaled $7,120--approximately half the charges of the surgically treated patients. A full 90 percent of this total was accounted for by the hospital portion of the bill, which included an average length of stay of 4.1 days. Of the states with at least 50 admissions, the total charges ranged from a high of $20,040 in California to a low of $10,070 in Washington State for patients with surgical back claims. Among the states with at least 50 admissions, the California total charge was also the highest for the medically treated back problem patients ($11,460), but the lowest total charge was registered in Indiana ($5,490). Total average hospital charges (room and board and ancillary fees) were $7,610 for the surgical back patients and $6,430 for the medically treated back patients. Ancillary fees were 84 and 73 percent of the hospital charges to insurance for surgical back and medical back claims, respectively. Physician fees averaged $6,380 for the surgical category and $690 for the medically treated group of patients.
