Objective: To determine which method is more effective – cranial halo traction or temporary internal distraction – in staged surgeries for patients with severe (≥ 100°) and stiff (<25% flexibility) scoliosis. Methods: A sample of 12 patients with traction and 7 patients without traction, operated on between January 2013 and December 2017. The patients’ demographic data, the type of surgery performed, complications, and coronal and sagittal alignment parameters were recorded before surgery and in the final follow-up. The data were processed in SPSS 20.0. Comparisons were made between the means (Student's t-test) and the clinical and procedure-related characteristics (likelihood ratio and Fisher's Exact tests), at a confidence level of 0.05. Results: There were no significant intergroup differences for clinical characteristics, complications or degree of correction. However, more patients in the group submitted to temporary internal distraction required vertebral resection osteotomies during definitive surgery (p<0.05). Conclusions: Based on the results, it was not possible to establish which is the most effective method, but it is suggested that staged traction may be more effective, and safer, particularly when the surgeon is less experienced, during surgery on patients with severe and stiff scoliosis. Level of evidence IV; Vase series.

Objetivos: Identificar o perfil microbiológico da Unidade de Terapia Intensiva de um Hospital Geral de referência para síndrome respiratória aguda grave causada pelo coronavírus (SARS-CoV-2) Recife – Pernambuco. Métodos: Trata-se de um estudo descritivo e retrospectivo, com abordagem quantitativa. Resultados: Observou-se uma predominância de infecção da corrente sanguínea. Quanto aos microorganismos detectados, foram identificadas 18 espécies isolados, com maior representatividade do Sthaphylococcus haemolyticus, Sthaphylococcus epidermidis, Acinetobacter baumannii e Sthaphylococcus spp, respectivamente. As cepas se mostraram mais resistentes a ciprofloxacina, levofloxacina, penicilina, oxacilina e eritromicina, respectivamente. Conclusão: Os resultados apresentados corroboram com os achados da literatura sobre o perfil microbiológico nas unidades de terapia intensiva do País. Recomenda-se a utilização das informações na melhoria das políticas de prevenção de controle de infecção hospitalar, por meio de padronização de antimicrobianos, atividades educativas para controle de infecção e elaboração de protocolos institucionais.
