Brain-dead Donation Rate in Month of Ramadan and the other Months: 2005-2014.

Regardless of the level of development, religion and beliefs have crucial impact on people's attitude towards organ donation. Although organ donation in Islam is obviously appraised, mainly due to lack of an appropriate infrastructure, post-mortem donation rate in Islamic countries is not comparable to successful settings. We conducted this study to assess the extent of contribution of factors that reduce the level of effectiveness, and also to determine the impact of altruistic feelings in the month of Ramadan on family refusal as the leading modifiable contributor to organ donation rate. All records of potential and actual brain-dead donors, referred to Organ Procurement Unit of the Iranian Tissue Bank, from January 1, 2005 to December 31, 2014, were analyzed. In each year, the number of potential and actual donors in the month of Ramadan was compared to the mean value in the remaining 11 months. Of 1758 total potential donors in 10 years, 464 cases became actual donors (26.4% as overall level of effectiveness). The reasons for non-effectiveness were medical contraindications (25.4%), cardiac arrest before referral or during maintenance (7.4%), family refusal (30.8%), judicial refusal (8.7%), etc (1.3%). Analysis showed no significant differences between donation rates (both potential and actual) in Ramadan and non-Ramadan months for potential (Δ=3.55, 95% CI: -6.7 to 13.8) and actual donors (Δ=1.35, 95% CI: -2.3 to 5). Despite the undeniable role of religion and beliefs in the establishment of organ procurement program from brain-dead donors, there was no monthly variability in post-mortem organ donation rate.

Rate of family refusal of organ donation in dead-brain donors: the Iranian tissue bank experience.

BACKGROUND: The growing gap between organ supply and demand remains a worldwide serious problem. Losing dead-brain donor organs can be attributed to several reasons including un-recognition of potential donor by ICU staff, death before official declaration of brain death and high refusal rate of deceased donors' families. OBJECTIVE: To study the trend of dead-brain patients' relatives refusal of organ donation from 2007 to 2011. METHODS: This study was a retrospective review of all patients who had been introduced as brain death to the organ procurement unit (OPU) of Iranian Tissue Bank between April 2007 and April 2012 according to preliminary neurological exam performed in the hospital of origin. The refusal rate of dead-brain patients' families and its reasons was evaluated. RESULTS: A total of 874 ICU admitted patients with severe brain injury (Glasgow coma score <7) was introduced to our center and were visited by the coordinator team during April 2007 to April 2012. 412 (47%) patients were excluded from the study mainly due to unsuitability for donation according to the approved medical protocols (n=205) and not fulfilling the brain death criteria (n=66). The families of the remaining cases (n=462) had been interviewed 343 (74.2%) of whom permitted donation. The mean±SD age of donors was 29.8±13.2 years; the male/female ratio was almost 2. The most common reason of brain death was traffic collision (n=120; 56.3%) and cerebrovascular accidents (n=40; 18.8%). The refusal rate from 2007 to 2011 has decreased respectively, from 30.4% to 20% in Tehran, and from 57.1% to 51.6% in other cities. The overall refusal rate was 25.8%. CONCLUSION: Our study confirmed that more level of expertise of the coordinator team and continuous public education, would result in higher rate of consent to organ donation.

Hemodynamic factors affecting the suitability of the donated heart and kidney for transplantation.

BACKGROUND: Due to the loss of autonomic nervous system, precise control of the hemodynamic status in dead brain potential donors presents a clinical dilemma. In these patients, due to head trauma and cerebral edema, fluids administration is restricted. Moreover, the decreased central venous pressure may put the viability of the organs at risk. OBJECTIVE: To investigate hemodynamic factors affecting the suitability of the donated heart and kidney for transplantation. METHODS: Data were retrospectively collected from the maintained databases of all dead-brain donors (DBDs) admitted to our organ procurement unit (OPU) ICU between 1999 and 2008. In this study, laboratory variables in addition to demographic data were collected. The time between donor entrance to the DBD ICU and organ procurement, vital signs, hourly urine output, amount of IV fluid administered, and the dosage of vasopressor and desmopressin were recorded. The end-point of the study was organ suitability for organ retrieval. RESULTS: A total of 132 dead brain donors were studied. The mean±SD age of the donors was 26.3±12.2 years. The main cause of brain death was multiple trauma (53%). The organ retrieval rate was 82.6% for the kidney, 59.8% for the liver, and 53% for the heart. 83 (63%) and 106 (80.3%) donors had suitable hearts and kidneys, respectively. 66 cases did not receive desmopressin (50.4%) at all. The mean±SD dose of desmopressin the donors received was 7±1 µg. There was a significant association between the suitability of these two organs for transplantation and the dosage of the administered desmopressin and volume of IV solution the donors received. CONCLUSION: Fluid therapy and administration of desmopressin can improve the number and quality of retrieved organs from dead brain donors.
