Abstract
FUNDAMENTO: Hiponatremia e fenômenos congestivos indicam mau prognóstico na insuficiência cardíaca descompensada. A ocorrência de insuficiência renal está associada a aumento do risco de morte. OBJETIVO: Avaliar a segurança e a eficácia da solução hipertônica em pacientes com insuficiência cardíaca descompensada para prevenção de insuficiência renal. MÉTODOS: Participaram do estudo pacientes com insuficiência cardíaca descompensada, congestão e hiponatremia. Além do tratamento padrão, os pacientes receberam solução salina hipertônica, e foram submetidos a avaliação tanto clínica como laboratorial. RESULTADOS: Foram incluídos 9 pacientes. A média das idades dos pacientes foi de 55 + 14,2 anos, sendo 5 (55,5%) do sexo masculino e 4 (44,5%), do feminino. Todos apresentavam classe funcional III-IV da New York Heart Association (NYHA), e 5 (55,5%) recebiam dobutamina. Todos apresentaram creatinina inicial acima de 1,4 mg/dl. A tonicidade média da solução foi de 4,39% + 0,018% (2,5% a 7,5%) e a duração do tratamento foi de 4,9 dias + 4,1 dias (1 dia a 15 dias). Não houve efeitos adversos graves; em nenhum caso houve piora clínica ou distúrbios neurológicos; hipocalemia ocorreu em 4 (44,5%) casos. A comparação das variáveis pré- e pós-tratamento demonstrou queda da uréia (105 mg/dl + 74,8 mg/dl vs. 88 mg/dl + 79,4 mg/dl; p = 0,03) e aumento do volume urinário (1.183 ml/dia vs. 1.778 ml/dia; p = 0,03); houve tendência a redução da creatinina (2,0 mg/dl + 0,8 mg/dl vs. 1,7 mg/dl + 1,0 mg/dl; p = 0,08). Apesar da elevação do valor do sódio (131 mEq/l + 2,8 mEq/l vs. 134 mEq/l + 4,9 mEq/l) e da redução do peso (69,5 kg + 18,6 kg vs. 68,2 kg + 17,1 kg), não houve diferença estatisticamente significante. CONCLUSÃO: O uso de solução salina hipertônica em pacientes com insuficiência cardíaca descompensada pode ser método terapêutico seguro e potencialmente relacionado a melhora clínica e de prevenção da insuficiência renal.
BACKGROUND: Hyponatremia and congestive phenomena indicate a bad prognosis in decompensated heart failure. The occurrence of renal failure is associated to an increased death risk. OBJECTIVE: To evaluate the safety and efficacy of the hypertonic saline solution in patients with decompensated heart failure for renal failure prevention. METHODS: Patients with decompensated heart failure, congestion and hyponatremia participated in the study. In addition to the standard treatment, the patients received hypertonic saline solution and were submitted to clinical as well as laboratory assessment. RESULTS: Nine patients were enrolled in the study. Mean age was 55 + 14.2 years, being 5 male (55.5%) and 4 (44.5%) female patients. All of them presented functional class III-IV of the New York Heart Association (NYHA), and 5 (55.5%) received dobutamine. All of them presented initial creatinine > 1.4 mg/dl. The mean tonicity of the solution was 4.39% + 0.018% (2.5% to 7.5%) and the duration of treatment was 4.9 days + 4.1 days (1-15 days). There were no severe adverse effects; none of the patients presented clinical worsening or neurologic disorders; hypokalemia occurred in 4 cases (44.5%). The comparison of the variables before and after treatment showed a decrease in urea (105 mg/dl + 74.8 mg/dl vs. 88 mg/dl + 79.4 mg/dl; p = 0.03) and increase in the urinary volume (1,183 ml/day vs. 1,778 ml/day; p = 0.03); there was no tendency to creatinine decrease (2.0 mg/dl + 0.8 mg/dl vs. 1.7 mg/dl + 1.0 mg/dl; p = 0.08). Despite the elevation in sodium levels (131 mEq/l + 2.8 mEq/l vs. 134 mEq/l + 4.9 mEq/l) and weight decrease (69.5 kg + 18.6 kg vs. 68.2 kg + 17.1 kg), there was no statistically significant difference. CONCLUSION: The use of hypertonic saline solution in patients with decompensated heart failure can be a safe therapeutic method and potentially related to clinical improvement and renal failure prevention.
