RESUMO
OBJECTIVE: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. METHODS: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. RESULTS: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. CONCLUSION: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.
OBJETIVO: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. MÉTODOS: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. RESULTADOS: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. CONCLUSÃO: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.

OBJECTIVES: Critically ill cancer patients are at increased risk for acute kidney injury, but studies on these patients are scarce and were all single centered conducted in specialized intensive care units. The objective was to evaluate the characteristics and outcomes in a prospective cohort of cancer patients admitted to several intensive care units with acute kidney injury. METHODS: Prospective multicenter cohort study conducted in intensive care units from 28 hospitals in Brazil over a two-month period. Univariate and multivariate logistic regression were used to identify factors associated with hospital mortality. RESULTS: Out of all 717 intensive care unit admissions, 87 (12%) had acute kidney injury and 36% of them received renal replacement therapy. Kidney injury developed more frequently in patients with hematological malignancies than in patients with solid tumors (26% vs. 11%, P=0.003). Ischemia/shock (76%) and sepsis (67%) were the main contributing factor for and kidney injury was multifactorial in 79% of the patients. Hospital mortality was 71%. General and renal-specific severity-of-illness scores were inaccurate in predicting outcomes for these patients. In a multivariate analysis, length of hospital stay prior to intensive care unit, acute organ dysfunctions, need for mechanical ventilation and a poor performance status were associated with increased mortality. Moreover, cancer-related characteristics were not associated with outcomes. CONCLUSIONS: The present study demonstrates that intensive care units admission and advanced life-support should be considered in selected critically ill cancer patients with kidney injury.
RESUMO
OBJETIVOS: Pacientes com câncer criticamente enfermos têm maior risco de lesão renal aguda, mas estudos envolvendo estes pacientes são escassos, e todos em centros únicos e realizados em unidades de terapia intensiva especializadas. O objetivo deste estudo foi avaliar as características e desfechos em uma coorte prospectiva de pacientes de câncer internados em diversas unidades de terapia intensiva com lesão renal aguda. MÉTODOS: Estudo prospectivo multicêntrico de coorte realizado em unidades de terapia intensiva de 28 hospitais brasileiros em um período de dois meses. Foram utilizadas regressões logísticas univariada e multivariada para identificar os fatores associados a mortalidade hospitalar. RESULTADOS: Dentre todas as 717 internações a unidades de terapia intensiva, 87 (12 por cento) tiveram lesão renal aguda e 36 por cento deles receberam terapia de substituição renal. A lesão renal se desenvolveu mais frequentemente em pacientes com neoplasias hematológicas do que em pacientes com tumores sólidos (26 por cento x 11 por cento; p=0,003). Isquemia/choque (76 por cento) e sepse (67 por cento) foram os principais fatores associados à lesão renal, e esta foi multifatorial em 79 por cento dos pacientes. A letalidade hospitalar foi de 71 por cento. Os escores de gravidade gerais e específicos para pacientes com lesão renal, foram imprecisos para predizer o prognóstico nestes pacientes. Na análise multivariada, a duração da internação hospitalar antes da unidade de terapia intensiva, disfunções orgânicas agudas, necessidade de ventilação mecânica e um performance status comprometido associaram-se à maior letalidade. Mais ainda, características relacionadas ao câncer não se associaram com os desfechos. CONCLUSÕES: O presente estudo demonstra que internação na unidade de terapia intensiva e suporte avançado à vida devem ser considerados em pacientes selecionados de câncer criticamente enfermos com lesão renal.
