Conhecimento do enfermeiro para identificação precoce da Injúria Renal Aguda

OBJETIVO Avaliar o conhecimento do enfermeiro na identificação precoce da Injúria Renal Aguda (IRA) em Unidade de Terapia Intensiva, Unidade de Internação e Emergência. MÉTODO Estudo multicêntrico, prospectivo.Participaram do estudo 216 enfermeiros,por meio de questionário com 10 questões relacionadas à prevenção, ao diagnóstico e ao tratamento da IRA. RESULTADOS 57,2% não souberam identificar as manifestações clínicas da IRA, 54,6% não têm conhecimento da incidência de IRA em pacientes internados na UTI, 87,0% dos enfermeiros não souberam responder ao índice de mortalidade de IRA em pacientes internados na UTI, 67,1% responderam incorretamente que aumentos discretos da creatinina sérica não têm impacto na mortalidade, 66,8% responderam incorretamente à questão sobre as medidas de prevenção da IRA, 60,4% acertaram quando responderam que não é recomendada a utilização de diuréticos de alça na prevenção da IRA, 77,6% acertaram ao responder que IRA não caracteriza necessidade de hemodiálise e 92,5% disseram não conhecer a classificação AKIN. CONCLUSÃO Enfermeiros não têm conhecimento suficiente para a identificação precoce da IRA, mostrando a importância de programas de capacitação nesta área do conhecimento.OBJETIVO Evaluar el conocimiento del enfermero en la identificación precoz de la Insuficiencia Renal Aguda (IRA) en Unidad de Cuidados Intensivos, Unidad de Estancia Hospitalaria y Urgencias.

METHOD A prospective multi-center study was conducted with 216 nurses, using a questionnaire with 10 questions related to AKI prevention, diagnosis, and treatment. RESULTS 57.2% of nurses were unable to identify AKI clinical manifestations, 54.6% did not have knowledge of AKI incidence in patients admitted to the ICU, 87.0% of the nurses did not know how to answer as regards the AKI mortality rate in patients admitted to the ICU, 67.1% answered incorrectly that slight increases in serum creatinine do not have an impact on mortality, 66.8% answered incorrectly to the question on AKI prevention measures, 60.4% answered correctly that loop diuretics for preventing AKI is not recommended, 77.6% answered correctly that AKI does not characterize the need for hemodialysis, and 92.5% said they had no knowledge of the Acute Kidney Injury Networkclassification. CONCLUSION Nurses do not have enough knowledge to identify early AKI, demonstrating the importance of qualification programs in this field of knowledge

Hemodiálise estendida em lesão renal aguda

Cerca de 10% dos pacientes em unidade de terapia intensiva que desenvolvem injúria renal aguda irão depender de terapia renal substitutiva. Embora não existam dados que comprovem redução da mortalidade, quando comparadas às terapias intermitentes, as terapias contínuas fornecem maiores doses de diálise cumulativa e maior estabilidade hemodinâmica. Contudo, apresentam custos elevados e não estão disponíveis em vários centros. Nesse contexto, a Hemodiálise Estendida ganha espaço na prática clínica, pois combina a tolerabilidade hemodinâmica, o controle de soluto lento e sustentado e as doses efetivas de diálise das terapias contínuas associadas aos custos reduzidos e facilidades logísticas das terapias intermitentes

Impact of an Electronic Alert in Combination with a Care Bundle on the Outcomes of Acute Kidney Injury

Early diagnosis is essential for the appropriate management of acute kidney injury (AKI). We evaluated the impact of an electronic AKI alert together with a care bundle on the progression and mortality of AKI. This was a single-center prospective study that included AKI patients aged ≥ 18 years, whereas those in palliative care, nephrology, and transplantation departments were excluded. An AKI alert was issued in electronic medical records and a care bundle was suggested. A series of classes were administered to the multidisciplinary teams by nephrologists, and a clinical pharmacist audited prescriptions. Patients were categorized into pre-alert and post-alert groups. The baseline characteristics were comparable between the pre-alert (n = 1613) and post-alert (n = 1561) groups. The 30-day mortality rate was 33.6% in the entire cohort and was lower in the post-alert group (30.5% vs. 36.7%; p < 0.001). Age, pulmonary disease, malignancy, and ICU admission were associated with an increase in 30-day mortality. The electronic AKI alert together with a care bundle and a multidisciplinary education program was associated with a reduction in 30-day mortality in patients with AKI

Involvement of Opioid System, TRPM8, and ASIC Receptors in Antinociceptive Effect of Arrabidaea brachypoda (DC) Bureau

Arrabidaea brachypoda (DC) Bureau is a medicinal plant found in Brazil. Known as "cipó-una", it is popularly used as a natural therapeutic agent against pain and inflammation. This study evaluated the chemical composition and antinociceptive activity of the dichloromethane fraction from the roots of A. brachypoda (DEAB) and its mechanism of action. The chemical composition was characterized by high-performance liquid chromatography, and this fraction is composed only of dimeric flavonoids. The antinociceptive effect was evaluated in formalin and hot plate tests after oral administration (10-100 mg/kg) in male Swiss mice. We also investigated the involvement of TRPV1 (transient receptor potential vanilloid 1), TRPA1 (transient receptor potential ankyrin 1), TRPM8 (transient receptor potential melastatin 8), and ASIC (acid-sensing ion channel), as well as the opioidergic, glutamatergic, and supraspinal pathways. Moreover, the nociceptive response was reduced (30 mg/kg) in the early and late phase of the formalin test. DEAB activity appears to involve the opioid system, TRPM8, and ASIC receptors, clearly showing that the DEAB alleviates acute pain in mice and suggesting the involvement of the TRPM8 and ASIC receptors and the opioid system in acute pain relief
