Fatores associados ao insucesso no desmame ventilatório de crianças submetidas a cirurgia cardíaca pediátrica / Factors associated with failure in ventilatory weaning of children undergone pediatric cardiac surgery

OBJETIVO: Verificar os fatores associados ao insucesso no desmame de crianças submetidas a correção cirúrgica de cardiopatias congênitas. MÉTODOS: Estudo de coorte. A amostra foi composta de 29 crianças. As cardiopatias foram divididas em cianóticas (nove crianças) e acianóticas (20 crianças). Foram estudadas crianças de 0 a 5 anos, submetidas a cirurgia cardíaca com permanência em ventilação mecânica invasiva. RESULTADOS: O grupo insucesso apresentou valor menor na SpO2 e valores maiores nos dias de permanência em VMI e na FiO2 quando comparados ao grupo sucesso (P<0,05). Observou-se que quatro (14 por cento) crianças tiveram insucesso no desmame, sendo necessário retornar a prótese ventilatória antes de 48 horas após a extubação. CONCLUSÃO: Os dias de VMI, a SpO2 reduzida e a FiO2 elevada foram os principais fatores associados à falha na extubação neste grupo de pacientes.

OBJECTIVE: To assess factors associated with failure in ventilatory weaning of children undergone surgical correction of congenital heart diseases. METHODS: Cohort study with 29 children. The heart diseases were divided into cyanotic (nine children) and acyanotic (20 children). We studied children from 0 to 5 years who underwent heart surgery with invasive mechanical ventilation. RESULTS: The failure group presented smaller value in SpO2 and higher values during days of stay in IMV and FiO2 when compared to the success group (P<0.05). It was observed that 4 children (14 percent) had failed in weaning, being necessary to return the ventilatory prosthesis before 48 hours after extubation. CONCLUSION: The days of IMV, SpO2 and FiO2 were the main factors associated with failed extubation in this group of patients.

Aneurisma de canal arterial patente silencioso

Ductus arteriosus aneurysm, a rare and potentially fatal condition, has been reported as a complication after surgical ductus arteriosus closure. Its spontaneous appearance as a septic complication, which was common in the presurgical and preantibiotic era, has been rarely reported in the contemporary literature. Persistence of silent ductus arteriosus in healthy children and adults is a frequent condition that currently has an increasing diagnostic possibility due to the availability of more accurate investigative methods, especially echocardiography. We report the case of a 1-year-old child, in whom no previous heart disease was known, who developed a giant aneurysm of the ductus arteriosus during a staphylococcal infection. This complication appeared after craniotomy for emptying an accidental subdural hematoma. This report associates the persistence of ductus arteriosus with a complication considered rare, which has a rapidly fatal evolution
