Mandatory preoperative SARS-CoV-2 infection screening policies for paediatric surgery

SARS-CoV-2 RNA positive pediatric organ donors: A case report

BACKGROUND

Preliminary evidence suggests that non-lung organ donation from resolved, asymptomatic or mildly symptomatic SARS-CoV-2 infected adults may be safe. However, several biological aspects of SARS-CoV-2 infection differ in children and the risk for transmission and outcomes of recipients from pediatric donors with SARS-CoV-2 infection are not well described.

METHODS

We report two unvaccinated asymptomatic pediatric non-lung organ deceased donors who tested positive for SARS-CoV-2 RNA by RT-PCR. Donor One unexpectedly had SARS-CoV-2 RNA detected in nasopharyngeal swab and plasma specimens at autopsy despite several negative tests (upper and lower respiratory tract) in the days prior to organ recovery. Donor Two had SARS-CoV- 2 RNA detected in multiple nasopharyngeal swabs but not lower respiratory tract specimens (endotracheal aspirate and bronchoalveolar lavage) during routine surveillance prior to organ recovery and was managed with remdesivir and monoclonal antibodies prior to organ recovery.

RESULTS

Two hearts, two livers and four kidneys were successfully transplanted into seven recipients. No donor to recipient transmission of SARS-CoV-2 was observed and graft function of all organs has remained excellent for up to 7 months of followup.

CONCLUSIONS

Due to the persistent gap between organ availability and the number of children waiting for transplants, deceased pediatric patients with non-disseminated SARS-CoV-2 infection, isolated to upper and/or lower respiratory tract, should be considered as potential non-lung organ donors.

A retrospective report on the preoperative mandatory SARS-COV-2 infection screening in a single pediatric center. Is it time to stop testing our patients?

The novel coronavirus SARS-COV-2 (COVID-19) pandemic dramatically changed the workflow of healthcare professionals around the world. Surgical procedures were withheld and postponed in a scenario of fear and uncertainty. Despite numerous medical institutions having swiftly and widely implemented pre-operative screening protocols, cost-effective studies remain scarce specially when comparing to other mitigation measures such as the donning of masks and social distancing measures. The objective of our study is to report the monthly positivity rates of SARS-COV-2 infection in our service and compare our data with monthly positivity rates reported by the State Health Department. Between April, 2020, to February, 2022, 7,199 patients had the RT-PCR for SARS-COV-2 collected, with 187 (2.59%) testing positive for COVID-19. Most of them (62.1%) were asymptomatic. The most common symptoms were coryza (10.7%), fever (10%), and diarrhea (8.7%). Nonetheless, there were two deaths due to COVID-19 reported in our center. Further studies are necessary to elucidate the impact of pre-operative screening for SARS-COV-2 in asymptomatic patients.

Estudo retrospectivo de rastreamento pré-operatoria mandatória de SARS-COV-2 na população pediátrica. Será hora de parar de testar nossos pacientes?

RESUMO A pandemia causada pelo novo coronavírus (SARS-COV-2) alterou a rotina de pacientes, profissionais e serviços de saúde em todo o mundo levando ao adiamento ou suspensão de muitos procedimentos cirúrgicos. Muitos serviços implementaram protocolos de triagem sistemática pré-operatória para SARS-COV-2. No entanto, segue incerta a eficácia da triagem sistemática de pacientes assintomáticos para SARS-COV-2 quando comparada com outras medidas de mitigação como o uso de máscaras e o distanciamento social apesar da aparente sensação de segurança conferida pela testagem pré-operatória de pacientes para SARS-COV-2. Sendo assim, descrevemos a experiência de dois anos de um hospital pediátrico (n=7.199) na triagem sistemática pré-operatória para SARS-COV-2 e comparamos a taxa de positividade mensal reportada pelo serviço em relação a taxa de positividade mensal regional do Estado de São Paulo. No período de Abril de 2020 a Fevereiro de 2022 houveram 187 (2,56%) RT-PCR positivos para COVID-19 dos quais 62.1% assintomáticos. Os sintomas mais comuns foram coriza (10,7%), febre (10%) e diarreia (8,7%). Dois pacientes faleceram em decorrência de sintomas relacionados a COVID-19. Mais estudos são necessários para determinar o impacto da testagem pré-operatória de RT-PCR para SARS-COV-2 em pacientes assintomáticos na mitigação da transmissão intra-hospitalar e na morbidade cirúrgica.
