Relevance of routine testing in low-risk patients undergoing minor and medium surgical procedures.

BACKGROUND AND OBJECTIVES: Preoperative tests aim to reduce morbidity and mortality of surgical patients, cost of perioperative care, and preoperative anxiety. Clinical evaluation allows defining the need for additional tests and strategies to reduce the surgical-anesthetic risk. The aim of this study was to evaluate the benefit of routine preoperative testing of low-risk patients undergoing minor and medium surgical procedures. METHODS: A descriptive cross-sectional study of 800 patients seen at the preanesthetic assessment department of Hospital Santo Antonio, Salvador, BA. Patients with physical status ASA I, aged 1-45 years and scheduled to undergo elective minor and medium surgeries were include in the study. We evaluated changes in blood count, coagulation profile, electrocardiogram, chest X-ray, blood sugar, kidney function, sodium and potassium levels, and eventual change in clinical approach occurring due to these changes. RESULTS: Of 800 patients evaluated, a blood count was performed in 97.5%, coagulation in 89%t, electrocardiogram in 74.1%, chest X-ray in 62%, fasting glucose in 68%, serum urea and creatinine in 55.7%, and plasma levels of sodium and potassium in 10.1%. Of these 700 patients, 68 (9.71%) showed changes in preoperative routine tests and only 10 (14.7%) of the patients with abnormal tests had a preoperative modified approach (i.e., new tests ordered, referral to a specialist or surgery postponement). No surgery was suspended. CONCLUSION: We found that preoperative additional tests are excessively ordered, even for young patients with low surgical risk, with little or no interference in perioperative management. Laboratory tests, besides generating high and unnecessary costs, are not good standardized screening instruments for diseases.

Relevância de exames de rotina em pacientes de baixo risco submetidos a cirurgias de pequeno e médio porte / Relevance of routine testing in low-risk patients undergoing minor and medium surgical procedures / Relevancia de los exámenes de rutina en pacientes de bajo riesgo sometidos a cirugías menores

JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória tem como objetivos diminuir a morbimortalidade do paciente cirúrgico, o custo do atendimento perioperatório e a ansiedade pré-operatória. A partir da avaliação clínica deve-se definir a necessidade de exames complementares e estratégias para reduzir o risco anestésico-cirúrgico. O objetivo deste trabalho foi avaliar o benefício de exames de rotina pré-operatório de pacientes de baixo risco em cirurgias de pequeno e médio porte. MÉTODOS: Trata-se de um estudo descritivo, transversal, com 800 pacientes atendidos no consultório de avaliação pré-anestésica do Hospital Santo Antonio, Salvador, BA. Foram incluídos pacientes de 1 a 45 anos, estado físico ASA I, que seriam submetidos a cirurgias eletivas de pequeno e médio porte. Avaliaram-se alterações no hemograma, coagulograma, eletrocardiograma, RX de tórax, glicemia, função renal e dosagem de sódio e potássio e as eventuais mudanças de conduta que ocorreram decorrentes dessas alterações. RESULTADOS: Dos 800 pacientes avaliados, 97,5% fizeram hemograma, 89% coagulograma, 74,1% eletrocardiograma, 62% RX de tórax, 68% glicemia de jejum, 55,7% dosagens séricas de ureia e creatinina e 10,1% dosagens de sódio e potássio séricos. Desses 700 pacientes, 68 (9,71%) apresentaram alteração nos exames pré-operatórios de rotina e apenas 10 (14,7%) dos considerados alterados tiveram conduta pré-operatória modificada, ou seja, solicitação de novos exames, interconsulta ou adiamento do procedimento. Nenhuma das cirurgias foi suspensa. CONCLUSÃO: Observou-se que excessivos exames complementares são solicitados no pré-operatório, mesmo em pacientes jovens, de baixo risco cirúrgico, com pouca ou nenhuma interferência na conduta perioperatória. Exames aboratoriais padronizados não são bons instrumentos de screening de doenças, além de gerar gastos elevados e desnecessários.

OBJETIVOS Y JUSTIFICATIVA: La evaluación preoperatoria tiene el objetivo de disminuir la morbimortalidad del paciente quirúrgico, el coste de la atención perioperatoria y la ansiedad preoperatoria. A partir de la evaluación clínica debemos definir la necesidad de exámenes complementarios y de estrategias para reducir el riesgo anestésico-quirúrgico. El objetivo de este trabajo fue el de evaluar el beneficio de exámenes de rutina preoperatorio de pacientes de bajo riesgo en las cirugías menores. MÉTODOS: Se trata de un estudio descriptivo, transversal con 700 pacientes atendidos en la consulta de evaluación preanestésica del Hospital Santo Antonio, Salvador, BA. Fueron incluidos pacientes de 1 a 45 años, estado físico ASA I, que serían sometidos a cirugías electivas menores. Se evaluaron las alteraciones en el hemograma, el coagulograma, el electrocardiograma, RX de tórax, glucemia, función renal y dosificación de sodio y potasio, y los eventuales cambios de conducta que se suscitaron provenientes de esas alteraciones. RESULTADOS: De los 800 pacientes evaluados un 97,5% realizaron hemograma, 89% coagulograma, 74,1% electrocardiograma, 62% RX de tórax, 68% glucemia en ayunas, 55,7% dosificaciones séricas de urea y creatinina y un 10,1% dosificaciones de sodio y potasio séricos. De esos 800 pacientes, 68 (9,71%) tuvieron alteración en los exámenes preoperatorios de rutina y solo 10 (14,7%) de los considerados alterados tuvieron una conducta preoperatoria modificada, o sea, una solicitación de nuevos exámenes, interconsulta o la postergación del procedimiento. Ninguna de las cirugías se suspendió. CONCLUSIONES: Observamos que los excesivos exámenes complementarios se solicitaban en el preoperatorio, aunque fuese en los pacientes jóvenes y de bajo riesgo quirúrgico, con poca o ninguna interferencia en el conducta perioperatoria. Los exámenes laboratoriales estándares no son buenos instrumentos de screening de enfermedades y pueden generar gastos elevados e innecesarios.

The effect of 6% Hydroxyethyl starch vs. Ringer's lactate on acute kidney injury after renal ischemia in rats.

PURPOSE: To compare fluid replacement therapy with Hydroxyethyl starch 6% (HES) versus Ringer's lactate (RL) in a rodent model of non-septic renal ischemia. METHODS: Forty male Wistar rats were randomized to receive HES 2 ml.kg(-1).hr(-1) or RL 5 ml.kg(-1).hr(-1) that underwent 30 minutes of renal ischemia followed by reperfusion. Twelve hours after kidney ischemia, the kidneys were evaluated for histological changes. Serum NGAL levels were obtained at different times of the experimental protocol. RESULTS: Rodents in the HES group had a median (IQR) grade of renal injury 3 (3 to 5) compared to 2 (2 to 4) in the RL group (p=0.03). NGAL levels were not associated with the severity of kidney injury. CONCLUSION: Hydroxyethyl starch administration caused more kidney injury than Ringer's lactate in a non-infectious model of renal hypoperfusion.

NGAL como marcador precoce de lesão renal em ratos submetidos à isquemia renal sob anestesia geral balanceada / NGAL as an early marker of renal injury in rats submitted to renal ischemia under general balanced anesthesia

A lesão renal aguda (LRA) caracterizada como redução abrupta da função renal tem incidência variável, dependendo dos critérios utilizados para sua definição. Atualmente, o mais empregado para avaliação de função renal é a dosagem de creatinina plasmática, porém, por sofrer interferência de vários fatores faz com que a mesma não seja o marcador ideal. Um novo biomarcador da função renal, a lipocalina associada à gelatinase dos neutrófilos (NGAL), tem sido estudado como um dos mais precoces e sensíveis marcadores de lesão de rins após isquemia/reperfusão ou lesão nefrotóxica, sendo facilmente identificada no sangue e na urina. A classificação RIFLE para LRA com a validação da NGAL é uma nova perspectiva para o diagnóstico precoce da LRA e instituição de medidas preventivas e protetoras em situações de risco. O objetivo dessa pesquisa foi avaliar a LRA por meio da dosagem plasmática da NGAL em ratos submetidos à isquemia renal sob anestesia geral balanceada e hidratados com Ringer lactato ou com hidroxietilamido e correlacionar a dosagem da NGAL plasmática com a lesão histológica renal. Em trinta ratos Wistar machos (>350g) distribuídos aleatoriamente em três grupos de dez animais, induzidos com isoflurano a 4%, foi realizada intubação orotraqueal e colocados sob ventilação mecânica. Foram cateterizadas a artéria carótida esquerda e a veia jugular direita para monitorização e coletas sanguíneas. ETCO2, PAMI, T foram continuamente monitorizados (Datex, AS3)...

Acute renal injury (ARI), characterized by abrupt renal function decline, has variable incidence, depending on the criteria used for its definition. Presently, the criterion most often used for kidney function evaluation is plasma creatinine dosing; however, because it suffers interference, it is not an ideal marker. A new renal function biomarker, neutrophil gelatinase-associated lipocalin (NGAL) has been studied as one of the earliest and most sensitive kidney injury marker following ischemia/reperfusion or nephrotoxic injury, and it is easily identified in blood and urine. The RIFLE classification for ARI with NGAL validation is a new perspective for early ARI diagnosis and institution of preventive and protective measures in risk situations. This study aimed at evaluating ARI by means of NGAL plasma dosing in rats submitted to renal ischemia under general balanced anesthesia and hydrated with ringer lactate or hydroxyethylamide and at correlating plasma NGAL dosing with histological renal injury. Thirty male Wistar rats (>350g) were used. They were randomly distributed into three groups with ten animals each and induced by 4% isoflurane. Orotracheal intubation was performed and the animals were placed under mechanical ventilation. The left carotid artery and the right jugular vein were catheterized for monitorization and blood collection. ETCO2, PAMI, T were continuously monitorized (Datex, AS3)...

Uso do tramadol venoso e subcutâneo em herniorrafia inguinal: estudo comparativo / Intravenous and subcutaneous tramadol for inguinal herniorrhaphy: comparative study / Uso del tramadol venoso y subcutáneo en herniorrafía inguinal: estudio comparativo

JUSTIFICATIVA E OBJETIVOS: A herniorrafia inguinal é uma das cirurgias mais realizadas no homem. O bloqueio do neuroeixo é a técnica anestésica comumente utilizada e, na maioria das vezes, o paciente se encontra em condições para alta domiciliar algumas horas após o procedimento, desde que apresente analgesia satisfatória e ausência de náuseas e vômitos. O tramadol é um fármaco analgésico que pode ser utilizado para a analgesia pós-operatória, porém apresenta, como importantes efeitos colaterais, a presença de náuseas e vômitos, cuja incidência pode variar de 0 por cento a 50 por cento associada ao seu uso. O objetivo deste estudo foi comparar a incidência de náuseas e vômitos e a qualidade da analgesia pósoperatória do tramadol pela via subcutânea e endovenosa em pacientes submetidos à herniorrafia inguinal. METÓDO: Estudo prospectivo com 30 pacientes submetidos à herniorrafia inguinal. Foram divididos em dois grupos: Grupo C (n = 15) recebeu Tramadol 1,5 mg.kg-1 subcutâneo e Grupo V (n = 15) recebeu Tramadol 1,5 mg.kg-1 endovenoso. Para todos os pacientes, fez-se anestesia peridural contínua com levobupivacaína a 0,5 por cento. Foram registrados os dados antropométricos, qualidade de analgesia e ocorrência de náuseas e vômitos nas primeiras 8 horas do pós-operatório. RESULTADOS: Não houve diferença estatística entre os grupos com relação aos dados antropométricos, qualidade da analgesia e ocorrência de náuseas e vômitos. CONCLUSÕES: Conclui-se, neste estudo, que não existe diferença estatisticamente significante quanto à incidência de náuseas e vômitos e à qualidade da analgesia quando se utiliza o tramadol por via venosa e subcutânea.

BACKGROUND AND OBJECTIVES: Inguinal herniorrhaphy is one of the most common surgeries in men. Neuroaxis block is the anesthetic technique used more often and in the majority of the cases the patient is ready to be discharged from the hospital a few hours after the procedure, as long as satisfactory analgesia is present and nausea and vomiting are absent. Tramadol is an analgesic drug that can be used in postoperative analgesia, but it has important side effects, such as nausea and vomiting whose incidence can range from 0 percent to 50 percent. The objective of the present study was to compare the incidence of nausea and vomiting and the quality of postoperative analgesia of subcutaneous and intravenous tramadol in patients undergoing inguinal herniorrhaphy. METHODS: This is a prospective study with 30 patients undergoing inguinal herniorrhaphy. Patients were divided into two groups: Group C (n = 15) received 1.5 mg.kg-1 of subcutaneous Tramadol, and Group V (n = 15) received 1.5 mg.kg-1 of intravenous Tramadol. All patients underwent continuous epidural anesthesia with 0.5 percent levobupivacaine. Anthropometric data, quality of analgesia, and the development of postoperative nausea and vomiting in the first eight hours were recorded. RESULTS: Statistically significant differences were not observed between both groups for anthropometric data, quality of analgesia, and the development of nausea and vomiting. CONCLUSIONS: The present study demonstrates the absence of statistically significant differences regarding the incidence of nausea and vomiting and quality of analgesia when using intravenous and subcutaneous Tramadol.

Fueron registrados los datos antropométricos, la calidad de la analgesia y la incidencia de náuseas y vómitos en el postoperatorio (en las primeras ocho horas). RESULTADOS: No hubo diferencia estadística entre los grupos con relación a los datos antropométricos, calidad de la analgesia e incidencia de náuseas y vómitos. CONCLUSIONES: En este estudio llegamos a la conclusión de que no existe diferencia estadísticamente significante cuanto a la incidencia de náuseas y vómitos y a la calidad de la analgesia cuando se utiliza el tramadol por vía venosa y subcutánea.

Estratégia anestesiológica para cesariana em paciente portadora de deficiência de fator XI: relato de caso / Anesthetic strategy for cesarean section in a patient with factor XI deficiency: case report / Estrategia anestesiológica para cesárea en paciente portadora de discapacidad de factor XI: relato de caso

JUSTIFICATIVA E OBJETIVOS: A deficiência do fator XI é uma doença hematológica rara na população. A hemofilia C (deficiência do fator XI) ocorre em ambos os sexos e normalmente não apresenta qualquer sintomatologia, podendo manifestar-se apenas como hemorragia pós-cirúrgica. É uma doença autossômica recessiva, homozigótica ou heterozigótica, e sua gravidade depende dos níveis de fator XI. O objetivo desse relato foi apresentar a estratégia anestésica em paciente portadora de hemofilia C. RELATO DO CASO: Paciente com 32 anos, gesta I/para 0, 39 semanas de gestação programada para cesariana eletiva. Paciente portadora de deficiência de fator XI. Exame clínico e laboratorial sem alterações. Conforme orientação do hematologista, no dia da cesárea a paciente usou prometazina 25 mg; hidrocortisona 500 mg, devido a reações transfusionais prévias, e plasma 10 mL-1.kg-1 num total de 700 mL. Após 2 horas foi submetida ao bloqueio subaracnóideo sob monitorização de rotina. Hidratação com RL 2000 mL. Procedimento anestésico-cirúrgico sem intercorrências. A paciente evoluiu no pós-operatório sem intercorrências, sendo que no 3º DPO fez uso de plasma fresco congelado (PFC) 10.mL-1.kg-1 com o objetivo de evitar sangramento pós cirúrgico tardio. CONCLUSÕES: O objetivo do caso foi apresentar o protocolo anestésico para pacientes portadores de hemofilia C e alertar para a necessidade de investigação em caso de antecedente de sangramento pós-operatório, quando um estudo da coagulação deve ser realizado antes de qualquer procedimento invasivo e, se um TTPA prolongado for encontrado, torna-se imperativo pesquisar a deficiência desse fator.

BACKGROUND AND OBJECTIVES: Factor XI deficiency is a rare hematologic disorder. Hemophilia C (factor XI deficiency) affects both genders and it is usually asymptomatic, manifesting only as postoperative hemorrhage. It is an autosomal recessive, homozygous or heterozygous, disorder, and its severity depends on the levels of factor XI. The objective of this report was to present the anesthetic strategy in a patient with hemophilia C. CASE REPORT: This is a 32 years old female, gravida 1/para 0, on the 39th week of pregnancy, scheduled for elective cesarean section. Physical and laboratorial exams did not show any abnormalities. According to the recommendations of the hematologist, on the day of the procedure, the patient was given promethazine, 25 mg, hydrocortisone, 500 mg, due to prior transfusion reaction, and plasma, 10 mL.kg-1 for a total of 700 mL. Two hours later, the patient underwent subarachnoid block under routine monitoring. Ringer's lactate, 2000 mL, was administered for hydration. The anesthetic-surgical procedure proceeded without intercurrences. Postoperatively, the patient was doing well when, on the 3rd PO day, fresh frozen plasma (FFP), 10 mL.kg-1, was administered to prevent late postoperative bleeding. CONCLUSIONS: The objective of this report was to present the anesthetic protocol for patients with hemophilia C and to alert for the need of investigation in patients with a history of postoperative bleeding, when a coagulation study should e be done before any invasive procedure and, in the case of prolonged aPTT, one should investigate the presence of factor XI deficiency.
