Factors limiting renal transplantation program in Poland.

The shortage of donor organs has been the main obstacle to the expansion of transplantation programs. Recent public opinion survey documented acceptance of the cadaveric kidney procurement in our country but some reluctance to brain death and presumed consent concepts. Recently, the survey was carried out within the medical community to find out whether the level of knowledge and the attitude toward donation has an influence on the slow development of the transplantation program. A questionnaire was addressed to: 1010 general practitioners, neurosurgeons and anesthesiologists; 926 ICU and neurosurgical nurses and 1760 students of 12 medical schools of the country. Vast majority of doctors, nurses and last year medical students accept retrieval and transplantation of kidneys and the heart, but not of the liver. Acceptance of this procedure among junior medical students and university students was lower (78% vs 98%). Most of the respondents would agree to donate their kidneys and other organs, but 20% would protest against harvesting of the organs from their relatives. 100% of the physicians and 80% of medical students and nurses accept the brain death concept(which is accepted only by 60% of non medical university students) but only 44% of the doctors are prepared to switch off the respirator after diagnosis of brain death if harvesting is not taking place. Only half of the physicians would notify the transplantation unit about the possibility of organ retrieval. The reasons mentioned for such decision included fear of negative judgment of the local community and problems with deceased relatives. 60% of physicians talking to the family about retrieval would ask for the relatives' consent despite the fact, that the transplantation law in Poland is based on the presumed consent of each individual. The results of the knowledge survey among medical students documented inadequate medical education concerning problems of transplantation. Educational campaign is needed to promote and extend the cadaveric organ transplantation in our country.

In situ perfusion and UW solution used for storage did not decrease the incidence of ATN in kidneys harvested from hemodynamically unstable donors.

The incidence of acute tubular necrosis ATN after cadaveric kidney transplantation in our centre has been in the range of 50%. A prospective study was carried out in 1991 and 1992 to assess the effect of in situ perfusion and hypothermic storage of kidneys harvested from brain-dead haemodynamically stable and unstable donors. Three litres of Ringer's solution were used for in situ perfusion. In 40 cases, the kidneys were stored in Euro-Collins (EC) solution and in the other 78 cases, in University of Wisconsin (UW) solution. Among the factors that could contribute to ATN, we analysed warm ischaemia time, anastomosis time and cold storage time. Function was considered to be delayed if the patient required posttransplantation dialysis. The donors were considered haemodynamically unstable when hypotension before harvesting was present (BP < 70 mm Hg over 2 h) despite high doses (> 15 microg/kg per minute) of dopamine or when cardiac arrest occurred at the time of harvesting and oliguria had been present for at least 2 h. Haemodynamically stable donors with a BP greater than 80 mm Hg had a normal diuresis. In all donors in this group the dose of dopamine was lower than 10 microg/kg per minute. The study showed that storage in UW solution did not influence the incidence of ATN in kidneys harvested from haemodynamically unstable donors. Differences observed in our study were due to haemodynamic status preceding donor nephrectomy and length of cold storage time.
