ABSTRACT
ABSTRACT In the 1970s, acute peritoneal dialysis (PD) was widely accepted for the treatment of acute kidney injury (AKI), but this practice has declined in favor of extracorporeal therapies, mainly in developed world. The lack of familiarity with the use of PD in critically ill patients has also led to a lack of use even among those receiving maintenance PD. Renewed interest in the use of PD for AKI therapy has emerged due to its increasing use in low- and middle-income countries due to its lower cost and minimal infrastructural requirements. In high-income countries, the coronavirus disease 2019 pandemic saw PD for AKI used early on, where many critical care units were in crisis and relied on PD use when resources for other AKI therapy modalities were limited. In this review, we highlight the advantages and disadvantages of PD in AKI patients and indications and contraindications for its use. We also provide an overview of advances to support PD treatment during AKI, discussing PD access, PD prescription, complications related to PD, and its use in particular clinical conditions.
ABSTRACT
Abstract Sepsis is the most common cause of death in critically ill patients and it may be associated with multiorgan failure, including acute kidney injury (AKI). This situation can require acute renal support and increase mortality. Therefore, it is essential to administrate antimicrobials in dosis to achieve adequate serum levels, preventing overdosis and drug toxicity or underdosing and risk for resistance to antibiotics and higher mortality. To date, there aren't validated guidelines on antibiotic dosis adjustment in septic patients with AKI and the recommendations are extrapolated from studies conducted in non-critical patients with chronic kidney disease in end stage receiving chronic renal replacement therapy. This study aimed to review and discuss the complexity of that issue, considering the several factors related to the drugs removal: critically ill patient characteristics, antimicrobial properties and dialysis method.
Resumo A sepse é a principal causa de óbito em pacientes críticos e pode cursar com falência de vários órgãos, entre eles os rins, requerendo, com frequência, suporte renal agudo e elevando a mortalidade. Assim, torna-se imprescindível a administração de antimicrobianos em dose que garanta nível sérico adequado para evitar superdosagem e toxicidade medicamentosa ou ainda subdosagem e risco de resistência microbiana, ambas as situações contribuindo para maior mortalidade. Até o momento, não há diretrizes validadas para auxiliar no ajuste de dose de antibióticos nos pacientes sépticos com lesão renal aguda em suporte renal, sendo as recomendações extrapoladas de estudos realizados em pacientes não críticos e com doença renal em estádio final recebendo terapia renal substitutiva crônica. Esse estudo teve como objetivo revisar e discutir a complexidade desse assunto, levando em consideração os vários fatores relacionados à remoção de drogas: características do paciente crítico, propriedades dos antimicrobianos e método dialítico utilizado.
