RESUMO
Transfusion-Related Acute Lung Injury (TRALI) is an immune-inflammatory lung pathology that manifests within the first 6-72 hours after administration of blood products. However, due to reduced awareness of TRALI, it continues to be an underreported and often underdiagnosed complication of transfusion therapy. We report a case of a 6-year-old girl with myelodysplastic syndrome and TRALI developed in the first hour after platelet transfusion. Diagnosis of TRALI is based on the exclusion of etiologic factors such as volume overload and cardiogenic pulmonary edema following transfusion. Symptoms responded to high-flow oxygen therapy, so intubation was not attempted and full recovery was achieved.
RESUMO
BACKGROUND AND OBJECTIVES: This is a prospective, randomized, single-blind study. We aimed to compare the tracheal intubation conditions and hemodynamic responses either remifentanil or a combination of remifentanil and lidocaine with sevoflurane induction in the absence of neuromuscular blocking agents. METHODS: Fifty intellectually disabled, American Society of Anesthesiologists I-II patients who underwent tooth extraction under outpatient general anesthesia were included in this study. Patients were randomized to receive either 2µg/kg remifentanil (Group 1, n=25) or a combination of 2µg/kg remifentanil and 1mg/kg lidocaine (Group 2, n=25). To evaluate intubation conditions, Helbo-Hansen scoring system was used. In patients who scored 2 points or less in all scorings, intubation conditions were considered acceptable, however if any of the scores was greater than 2, intubation conditions were regarded unacceptable. Mean arterial pressure, heart rate and peripheral oxygen saturation (SpO2) were recorded at baseline, after opioid administration, before intubation, and at 1, 3, and 5 min after intubation. RESULTS: Acceptable intubation parameters were achieved in 24 patients in Group 1 (96%) and in 23 patients in Group 2 (92%). In intra-group comparisons, the heart rate and mean arterial pressure values at all-time points in both groups showed a significant decrease compared to baseline values (p=0.000) CONCLUSION: By the addition of 2µg/kg remifentanil during sevoflurane induction, successful tracheal intubation can be accomplished without using muscle relaxants in intellectually disabled patients who undergo outpatient dental extraction. Also worth noting, the addition of 1mg/kg lidocaine to 2µg/kg remifentanil does not provide any additional improvement in the intubation parameters.

JUSTIFICATIVA E OBJETIVOS: este é um estudo prospectivo, randômico e duplo-cego. Nosso objetivo foi comparar as condições de intubação endotraqueal e as respostas hemodinâmicas com o uso de remifentanil ou combinação de remifentanil e lidocaína em indução anestésica com sevoflurano sem agentes bloqueadores neuromusculares. MÉTODOS: cinquenta pacientes intelectualmente deficientes, estado físico ASA I-II, submetidos à extração dentária sob anestesia geral em ambulatório foram incluídos neste estudo. Os pacientes foram randomizados para receber 2 μg kg-1 de remifentanil (Grupo 1, n = 25) ou uma combinação de 2 μg kg-1 de remifentanil e 1 mg kg-1 de lidocaína (Grupo 2, n = 25). Para avaliar as condições de intubação, o sistema de pontuação de Helbo-Hansen foi usado. Em pacientes com 2 ou menos pontos em todas as pontuações, as condições de intubação foram consideradas aceitáveis, porém, se qualquer uma das pontuações fosse superior a 2, as condições de intubação seriam consideradas inaceitáveis. Pressão arterial média, frequência cardíaca e saturação periférica de oxigênio (SpO2) foram registradas no início do estudo, após a administração de opiáceos, antes da intubação e nos minutos 1, 3 e 5 após a intubação. RESULTADOS: parâmetros aceitáveis de intubação foram obtidos em 24 pacientes do Grupo 1 (96%) e em 23 pacientes do Grupo 2 (92%). Nas comparações intragrupo, os valores da frequência cardíaca e pressão arterial média em todos os momentod em ambos os grupos mostraram uma redução significativa em relação aos valores basais (p = 0.000). ...
