Aspects of deceased organ donation in paediatrics

Evaluation of Pediatric Brain Death and Organ Donation: 10-Year Experience in a Pediatric Intensive Care Unit in Turkey

OBJECTIVE

We aimed to investigate the rate of brain death (BD) determinations and organ donations (OD) in our tertiary pediatric intensive care unit (PICU), and to report the data on the demographic pattern and supplementary descriptive data on BD declarations.

METHODS

The study was designed as a retrospective, single-center, descriptive cohort study. We evaluated all children who were determined to meet the criteria for BD in our tertiary PICU between January 2011 and December 2020.

RESULTS

During study period, BD was identified in 24 patients among 225 total deaths (10.7%). Their median age was 85 months (8-214) and the male-to-female ratio was 1 : 1. The most common diagnosis was meningoencephalitis in 25%, followed by traumatic intracranial hemorrhage (16.7%). The median time from admission to PICU until BD diagnosis was 6.5 days. The time from the first BD physical examination to the declaration of BD was 27.5 hours. There was no statistically important difference between donors and non-donors. The apnea test (AT) was the most performed ancillary method (100%), followed by electroencephalogram (EEG) (66.7%), and magnetic resonance angiography or computed tomography angiography (MRA/ CTA) (54.2%). Hyperglycemia developed in 79.2% of the cases, and 70.8% developed diabetes insipidus (DI). Five patients (20.8%) were organ donors in study group. In the study, 13 solid organ and 4 tissue transplantations were performed after OD.

CONCLUSION

Awareness of the incidence and etiology may contribute to the timely diagnosis and declaration of brain death, and with the help of good donor care, may help in increasing OD rates in the pediatric population.

Simultaneous en-bloc pancreas and kidney transplantation from a small pediatric donor after circulatory death

Simultaneous pancreas and kidney transplantation (SPKT) is an effective treatment option for patients with type 1 diabetes and end stage renal disease. Increasing demands for organs for transplantation coupled with a rise in age and size of adult donors has led to greater utilization of pediatric donors, and with good outcomes. Nonetheless, there remains reticence among transplant surgeons to transplant pancreases from small pediatric donors despite the optimal characteristics and macroscopic features of the younger pancreas. We report a successful case of SPKT from a small pediatric donor and explore the aspects of potential concern that might have led some clinicians to decline these organs. We also discuss the measures taken to overcome potential obstacles to successful transplantation from this donor source, and the rationale behind them.

Organ Donation Following Neurologic and Circulatory Determination of Death

OBJECTIVES

To describe important considerations during the process of caring for critically ill children who may be potential organ donors and supporting the family during the death of their child.

DESIGN

Literature review and expert commentary.

MEASUREMENT AND MAIN RESULTS

Medical literature focusing on pediatric donation, best pediatric donation practices, donor management, and factors influencing donation were reviewed. Additional pediatric data were obtained and reviewed from the U.S. Organ Procurement and Transplantation Network. Achieving successful organ donation requires the coordinated efforts of the critical care team, organ donation organization, and transplant team to effectively manage a potential donor and recover suitable organs for transplantation. Collaboration between these teams is essential to ensure that all potential organs are recovered in optimal condition, to reduce death and morbidity in children on transplantation waiting lists as well as fulfilling the family's wishes for their dying child to become a donor.

CONCLUSIONS

Organ donation is an important component of end-of-life care and can help the healing process for families and medical staff following the death of a child. The process of pediatric organ donation requires healthcare providers to actively work to preserve the option of donation before the death of the child and ensure donation occurs after consent/authorization has been obtained from the family. Medical management of the pediatric organ donor requires the expertise of a multidisciplinary medical team skilled in the unique needs of caring for children after neurologic determination of death and those who become donors following circulatory death after withdrawal of life-sustaining medical therapies.

Organ and tissue donation in a regional paediatric intensive care unit: evaluation of practice

Approximately 2% of those on the organ transplant list in the UK are children. Early identification of donors and referral to organ donation teams (ODT) has proven to increase both the success rate of gaining consent and the number of organs actually retrieved. To evaluate the practice relating to organ donation for children receiving end-of-life care on a paediatric intensive care unit (PICU) measured against the National Guidelines. All children 0-18 who received their end-of-life care and died on the PICU. A retrospective cohort study of organ donation patterns including referral, approach, consent and donation. This involved a review of case notes on PICU between the years 2009 and 2014. One hundred five deaths were identified and 100 notes were examined and data analysed to ascertain if religion, age and length of stay on PICU impacted on practice. Eighty-six children met the early identification criteria for potential donors, 40 (46.5%) children were referred to the ODT and 33 (38.3%) families were approached regarding donation. Twenty-one (24.4%) families consented to donation. Seventeen donations took place with a total of 41 sets of organs/tissues retrieved. Despite the majority of children meeting early identification for potential donors, many were not being referred.

CONCLUSIONS

All children on end-of-life care should be referred for potential organ donation. Organ donation needs to be seen as a priority for hospitals as a part of routine end-of-life care to help increase referral rates and give families the opportunity to donate. Many paediatric deaths are not referred for consideration of organ donation, despite guidelines stating that this process should be standard of care. Further optimization of referral rates may aid in increasing the number of organs available for donation. What is Known: • Shortage of organs continues to be a national problem. • NICE guidelines state that all patients who are on end-of-life care should have the option of organ donation explored. • Required referral both increases the number of donors and organs donated. What is New: • The process of identifying and referring children for paediatric organ donation. • Identifies that children are still not being referred for organ donation. • Organ donation is still not a priority for hospitals.

The promise of organ and tissue preservation to transform medicine

The ability to replace organs and tissues on demand could save or improve millions of lives each year globally and create public health benefits on par with curing cancer. Unmet needs for organ and tissue preservation place enormous logistical limitations on transplantation, regenerative medicine, drug discovery, and a variety of rapidly advancing areas spanning biomedicine. A growing coalition of researchers, clinicians, advocacy organizations, academic institutions, and other stakeholders has assembled to address the unmet need for preservation advances, outlining remaining challenges and identifying areas of underinvestment and untapped opportunities. Meanwhile, recent discoveries provide proofs of principle for breakthroughs in a family of research areas surrounding biopreservation. These developments indicate that a new paradigm, integrating multiple existing preservation approaches and new technologies that have flourished in the past 10 years, could transform preservation research. Capitalizing on these opportunities will require engagement across many research areas and stakeholder groups. A coordinated effort is needed to expedite preservation advances that can transform several areas of medicine and medical science.

Elective ventilation to facilitate organ donation in infants with anencephaly: perinatal professionals' views and an ethical analysis

AIM

Following the elective ventilation and referral for organ donation of an infant with anencephaly, we sought local perinatal professionals' views of this practice.

METHODS

Anonymous online survey: demographics, ethical viewpoints and potential public/maternal perceptions (standard 5-part Likert scale and free text).

RESULTS

DEMOGRAPHICS

49 replies (38 female): 4 obstetricians, 14 neonatologists, 6 foetal clinicians, 23 nurses, 1 anaesthetist and 1 reproductive specialist.

EXPERIENCE

0.5-33 years (average 12). Twenty-one had experience of anencephalic delivery, and 10 reported pregnancy continued for religious reasons.

ETHICS

(i) 73% thought anencephalic donation acceptable, of which 64% supported elective ventilation, 20% neutral and 16% disagreed. (ii) Provision of treatments not in infant's strict best interest to facilitate donation: 22% strongly agreed, 36% agreed, 33% neutral and 9% disagreed. (iii) Accept ventilation to permit donation if societal benefit: 53% agreed, 33% neutral and 13% disagreed. (iv) Public opinion: 59% disagreed anencephalic donation would harm public opinion about donation and 19% agreed.

CONCLUSION

We found a supportive local environment for donation in the setting of anencephaly, including support for elective ventilation. Given this, and our ethical analysis, we recommend provision of organ donation information as part of palliative care counselling for women carrying a foetus with a condition likely to be fatal in infancy.

The potential for neonatal organ donation in a children's hospital

OBJECTIVE

Neonatal organ donation does not occur in the UK. Unlike in other European countries, Australasia and the USA death verification/certification standards effectively prohibit use of neurological criteria for diagnosing death in infants between 37 weeks' gestation and 2 months of age and therefore donation after neurological determination of death. Neonatal donation after circulatory definition of death is also possible but is not currently undertaken. There is currently no specific information about the potential neonatal organ donation in the UK; this study provides this in one tertiary children's hospital.

DESIGN

Retrospective mortality database, clinical document database and patient notes review.

SETTING

Neonatal and Paediatric Intensive Care in a tertiary children's hospital.

PATIENTS

Infants dying between 37 weeks' gestation and 2 months of age between 1 January 2006 and 31 October 2012. Potential assessed using current UK guidelines for older children and neonatal criteria elsewhere.

RESULTS

84 infants died with 45 (54%) identified as potential donors. 34 (40%) were identified as potential donors after circulatory definition of death and 11 (13%) were identified as being theoretical potential donors after neurological determination of death. 10 (12%) were identified as unlikely donors due to relative contraindications and 39 (46%) were definitely not potential donors.

CONCLUSIONS

With around 60 paediatric organ donors in the UK annually, there does appear significant potential for donation within the neonatal population. Reconsideration of current infant brain stem death guidelines is required to allow parents the opportunity of donation after neurological determination of death, together with mandatory training in organ donation for neonatal teams, which will also facilitate donation after circulatory definition of death.

Length of time from extubation to cardiorespiratory death in neonatal intensive care patients and assessment of suitability for organ donation

OBJECTIVE

A common concern for parents when end of life decisions are made is the length of time their baby may take to die. Postcardiac death organ donation is now becoming more common, along with neonatal organ donation. The aim was to determine the length of time from extubation until cardiorespiratory death (CRD) in neonatal intensive care patients and consideration of potential organ donation.

DESIGN

Retrospective review of medical records of neonates who died in a neonatal intensive care unit between 2000 and 2009.

PATIENTS

Data collected included gestation at birth, age at death, birth weight, reason for cessation of intensive care, inotrope and ventilation requirements, sedation and muscle relaxation prior to death, time from extubation to documented CRD. An assessment was made for potential suitability for consideration of organ donation with a gestation at birth ≥ 34 weeks and birth weight >2.0 kg.

RESULTS

117 neonates were included, median gestation 29 weeks and median birth weight 1220 grams. The median age at death was 4 days of age. The median time from discussing prognosis to death was 137 min. The median time from extubation to CRD was 30 min. Seven (6%) neonates were considered suitable for organ donation, and for these infants the median time from extubation to CRD was 120 min. Two neonates donated heart valves.

CONCLUSIONS

This provides a guide for grieving parents on time frames for the interval between extubation and CRD. More accurate postextubation CRD times are required to determine likely potential for postcardiac death organ donation.
