Evaluation of the systemic antiinflammatory effects of levosimendan in an experimental blunt thoracic trauma model.

BACKGROUND: Blunt thoracic injury often leads to pulmonary contusion and the development of acute respiratory distress syndrome, which carries a high risk of morbidity and mortality, originating from the local and systemic inflammatory states. This study aimed to investigate the local and systemic antiinflammatory effects of levosimendan in rat models of blunt chest trauma. METHODS: A total of 32 Wistar albino rats were randomly assigned to one of the following four groups: control, sham, low-dose levosimendan (LDL) (5 µg/kg loading dose for 10 min and 0.05 µg/kg/min intravenous infusion), and high-dose levosimendan (HDL) (10 µg/kg loading dose for 10 min and 0.1 µg/kg/min intravenous infusion). Blunt chest trauma was induced, and after 6 h, the contused pulmonary tissues were histopathologically and immunohistopathologically evaluated, serum TNF-α, IL-1ß, IL-6, and NO levels were biochemically evaluated. RESULTS: The mean arterial pressure was low throughout the experiment in the LDL and HDL groups, with no statistically difference between the groups. Levosimendan reduced the alveolar congestion and hemorrhage, which developed after inducing trauma. Neutrophil infiltration to the damaged pulmonary tissue was also reduced in both the LDL and HDL groups. In rats in which pulmonary contusion (PC) was observed, increased activation of nuclear factor kappa B was observed in the pulmonary tissue, and levosimendan did not reduce this activation. Both high and low doses of levosimendan reduced serum IL-1ß levels, and high doses of levosimendan reduced IL-6 and NO levels. TNF-α levels were not reduced. CONCLUSION: In conclusion, the results showed that in a rat model of PC, the experimental agent levosimendan could reduce neutrophil cell infiltration to damaged pulmonary tissues and the systemic expressions of some cytokines (IL-1ß, IL-6, and NO), thereby partially reducing and/or correcting pulmonary damage. Systemic inflammatory response that occurs after trauma could also be reduced.

Anesthesia for a child with Walker-Warburg syndrome.

BACKGROUND AND OBJECTIVES: Walker-Warburg Syndrome is a rare, autosomal recessive congenital muscular dystrophy manifested by central nervous system, eye malformations and possible multisystem involvement. The diagnosis is established by the presence of four criteria: congenital muscular dystrophy, type II lissencephaly, cerebellar malformation, and retinal malformation. Most of the syndromic children die in the first three years of life because of respiratory failure, pneumonia, seizures, hyperthermia and ventricular fibrillation. CASE REPORT: The anesthetic management of a two-months-old male child listed for elective ventriculo-peritoneal shunt operation was discussed. CONCLUSIONS: A careful anesthetic management is necessary due to the multisystem involvement. We reported anesthetic management of a two-months-old male child with Walker-Warburg Syndrome who was listed for elective ventriculo-peritoneal shunt operation.

Anestesia em criança com síndrome de Walker-Warburg / Anesthesia for a child with Walker-Warburg syndrome / Anestesia en niño con el síndrome de Walker-Warburg

Justificativa e objetivos: A síndrome de Walker-Warburg é uma distrofia muscular autossômica recessiva congênita rara, manifestada pelo sistema nervoso central com malformações oculares e possível envolvimento de vários sistemas. O diagnóstico é estabelecido pela presença de quatro critérios: distrofia muscular congênita, lisencefalia tipo II, malformação cerebelar e malformação da retina. A maioria das crianças com a síndrome morre nos primeiros três anos de vida por causa de insuficiência respiratória, pneumonia, convulsões, hipertermia e fibrilação ventricular. Relato de caso: É discutida a conduta anestésica em uma criança do sexo masculino, de dois meses, programada para cirurgia eletiva de derivação ventrículo-peritoneal. Conclusões: Uma abordagem anestésica cuidadosa é necessária por causa do envolvimento de vários sistemas. Relatamos a conduta anestésica em uma criança do sexo masculino de dois meses com síndrome de Walker-Warburg, que foi programada para cirurgia eletiva de derivação ventrículo-peritoneal. .
