Caracterização epidemiológica e causas da não doação por potenciais doadores de órgãos em morte encefálica / Epidemiological characterization and causes of non-donation by potential brain-dead organ donors / Caracterización epidemiológica y causas de la no donación de potenciales donantes de órganos en muerte cerebral

Objetivo: analisar as características epidemiológicas e causas da não efetivação do processo de doação de órgãos e tecidos de potenciais doadores em morte encefálica. Método: estudo transversal, com dados secundários do ano de 2019, obtidos de formulários de notificação de morte encefálica de pacientes com idade igual e superior a 18 anos, analisados descritiva e inferencialmente, após aprovação pelo comitê de ética. Resultados: notificadas 231 mortes encefálicas, com maior incidência de pessoas do sexo masculino, idade média de 48 anos e notificações dos hospitais públicos. Em Campo Grande, Mato grosso do Sul, observou-se maior número de notificações e o menor tempo entre a notificação e o primeiro exame clínico (RR: 4,01; IC 2,17-7,41; p<0,001). Entre os casos de não doação, 75,8% ocorreram por contraindicação médica e recusa familiar. Conclusão: houve predomínio de adultos jovens, não doadores de órgãos, cuja negativa da família deu-se pela vontade de manter o corpo íntegro.

Objective: to analyze the epidemiological characteristics and causes of non-completion of the organ and tissue donation process from potential brain-dead donors. Method: cross-sectional study, with secondary data from 2019, obtained from brain death notification forms of patients aged 18 years and over, analyzed descriptively and inferentially, after approval by the ethics committee. Results: 231 brain deaths were reported, with a higher incidence of males, average age of 48 years and notifications from public hospitals. In Campo Grande, Mato grosso do Sul, Brazil, there was a greater number of notifications and a shorter time between notification and the first clinical examination (RR: 4.01; CI 2.17-7.41; p<0.001). Among cases of non-donation, 75.8% occurred due to medical contraindication and family refusal. Conclusion: there was a predominance of young adults, non-organ donors, whose family's refusal was due to the desire to keep the body intact.

Conclusión: hubo predominio de adultos jóvenes, no donantes de órganos, cuya negativa familiar se debió al deseo de mantener el cuerpo íntegro.

Thyroid Hormonal Changes in Brain Death Donors / 대한구급학회지

BACKGROUND: We analyzed thyroid hormone values in brain death patients to determine the need for thyroid hormone replacement therapy. METHODS: We analyzed 111 brain death donors (77 males and 34 females, mean age, 41.1 years (range; 8 months -72 years) in Ajou University Hospital from 2000 to 2010. RESULTS: The mean values of thyroid hormones were T3; 72.5 ng/dl (normal range [NR] 60-181 ng/dl), T4; 5.0 microg/dl (NR 4.5-10.9 microg/dl), free T4 1.0 ng/dl (NR 0.8-1.5 ng/dl), and TSH 1.5 microIU/ml (NR 0.35-5.5 microIU/ml), respectively. However, the values of T4 (correlation coefficient -0.264, p = 0.005), free T4 (correlation coefficient -0.305, p = 0.001) and TSH (correlation -0.206, p = 0.031) significantly decreased based on the increase of interval from the brain death-inducing event to the evaluation time (hereafter, interval). The patients with greater than 8 days of interval (N = 30) showed significantly low thyroid hormone values compared to patients with less than 8 days of interval (N = 81); T3 (70.3 ng/dl vs. 77.0 ng/dl, p = 0.242), T4 (4.7 ng/dl vs. 5.3 ng/dl, p = 0.015), free T4 (0.8 ng/dl vs. 1.2 ng/dl, p = 0.006) and TSH (1.0 microIU/ml vs. 2.0 microIU/ml, p = 0.000), respectively. CONCLUSIONS: As the intervals from the brain death-inducing events increased, all thyroid hormone values of brain death donors except T3 significantly decreased. Therefore, we recommend that careful consideration should be given to the interval from brain death-inducing event for the evaluation of thyroid hormone status of brain death patients.

Clinical Analysis of 10 Years Brain Death Donors in Single Center after Korean Network for Organ Sharing / 대한이식학회지

BACKGROUND: Brain-death donation became legal in Korea after "The law of organ transplantation" was established at 2000. Therefore, in this study, we report on the clinical analysis of brain-death donors at Ajou University Hospital since the Korean Network for Organ Sharing (KONOS) was launched in the year 2000. METHODS: We reviewed 90 brain-death donors who were managed at Ajou University Hospital from 2000 to 2009 and we retrospectively analyzed the clinical characteristics. RESULTS: The number of brain-death donors was 29 from 2000 to 2005 and 61 from 2006 to 2009, and this showed an increasing tendency. Forty-three brain-death donors (47.8%) were detected at our hospital and 47 donors (52.2%) were from referring hospitals. The percent of brain-death donors at our hospital was 31.0% from 2000 to 2005 and 55.7% from 2006 to 2009 (P=0.042). The mean age of the brain-death donors was 36.3 years (range: 8 months~70 years) and the fifth decade was the most common (25.6%). The gender ratio showed significant difference (P=0.001); there were 60 male donors (66.7%) and there were 30 females (33.3%). The most common cause of brain-death was cerebrovascular disease/stroke (48 donors, 53.3%) followed by traffic accident (15 donors, 16.7%). The most common blood type was Rh+ O (35.6%). The mean number of harvested organs was 3.9 and one donor (1.1%) had the largest number of harvested organs (9) (liver, 2 kidneys, pancreas, heart, lung, 2 corneas, tissue). The mean time to procurement was 3.6 days (range: 2~24 days). CONCLUSIONS: We recommend active discovery and evaluation of brain-death donors in all the hospitals including the hospital organ procurement organization (HOPO).

The management of single brain death donor for the successful five organs transplantation.

The demand of organs for transplantation in Thailand has been increasing enormously since the successful transplantation became well established. However there is the limited number of available cadaveric donors. One of the solutions for this problem is the maximal use of the organs from a single donor. The proper assessment and care of donor, good surgical techniques and well-organized coordination system could make significant contributions to successful multiorgan retrievals. We report the management of the first single cadaveric donor to bring five organs i.e., heart, lung, liver and both kidneys for the successful transplantations.
