Abstract

fetched live from OpenAlex

Jeune Syndrome or Asphyxiating Thoracic Dystrophy is a recessive autosomal disease. This syndrome is characterized by a bone dysplasia with varied abnormalities: thoracic, pancreatic, cardiac, hepatic, renal and retinal. Patients’ age when the clinical condition is experienced correlates with the disease severity. These patients experience polychondrodystrophy with large, short, horizontal ribs and irregular costochondral junctions resulting in a rigid and reduced thoracic cage with varied respiratory injury level. Male patient, 4 months-old, 7 kg, suffering with Asphyxiating Thoracic Dystrophy, intubated and presented with reduced thoracic cage. Echocardiogram: mild pulmonary hypertension. Chest tomography: pulmonary hypoplasia. Patient submitted to bilateral thoracoplasty and thoracotomy with general anesthesia. Anesthesia maintenance: sufentanil e sevoflurane continuous infusion. Ventilation parameters: pressurecycled mechanical ventilation. Thorax opening provided improvement of the ventilation parameters, but after thoracic prosthesis placement, ventilation was limited. Reduction of the thoracic prosthesis was considered with consequent improvement of ventilation. Diagnosis of all present abnormalities is essential for the correct anesthetic management. Observation was necessary to adequate pre- and post-thoracotomy/thoracoplasty ventilation and to maintain patient hemodynamically stable. Pressure-cycled mechanical ventilation is the most adequate type of ventilation to overcome the mechanical barrier. In the intraoperative setting, the ideal is to maintain the inspiratory pressure peak as low as possible to minimize the risk of barotrauma, venous return impairment and reduced cardiac output. Síndrome de Jeune, ou Distrofia Torácica Asfixiante, é uma doença autossômica recessiva. Esta síndrome é caracterizada por uma displasia óssea com variadas anormalidades: torácica, pancreática, cardíaca, hepática, renal e da retina. A idade em que o quadro clínico dos pacientes se apresenta está correlacionada com a gravidade da doença. Esses pacientes apresentam policondrodistrofia com costelas largas, curtas, horizontais e junções costocondrais irregulares levando a uma caixa torácica rígida e reduzida com grau de injúria respiratória variado. Paciente do sexo masculino, 4 meses, 7 kg, portador de Distrofia Torácica Asfixiante. Apresentava-se intubado e com caixa torácica reduzida. Ecocardiograma: hipertensão pulmonar leve. Tomografia de tórax: hipoplasia pulmonar. Submetido à toracoplastia bilateral e toracotomia sob anestesia geral. Manutenção da anestesia: infusão contínua de sufentanil e sevoflurano. Parâmetros ventilatórios: ventilação mecânica ciclada à pressão. Com a abertura do tórax, houve melhora dos parâmetros ventilatórios e, após o posicionamento da prótese torácica, observou-se limitação ventilatória. Decidiu-se pela diminuição da prótese torácica com consequente melhora da ventilação. É imprescindível o diagnóstico de todas as anormalidades presentes para o correto manejo anestésico. Foi necessária observação para adequar ventilação pré- e pós-toracotomia/toracoplastia e para manter o paciente hemodinamicamente estável. A forma mais adequada para ventilação mecânica é a ciclada à pressão para vencer a barreira mecânica. No intraoperatório, é desejável manter o pico de pressão inspiratória o mais baixo possível para minimizar o risco de barotrauma, de impedimento do retorno venoso e diminuição do débito cardíaco.

Con la abertura del tórax, se notó una mejoría de los parámetros ventilatorios y después del posicionamiento de la prótesis torácica, se observó una limitación ventilatoria.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
