RESUMO

The objective of this study is to analyze incidence and risk factors for intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in major burn patients. Aprospective cohort study was conducted at a Burns Treatment Center, including all patients with a burned body surface area ≥20% admitted from August 2015 to January 2018. Intra-abdominal pressure was measured periodically during the first week of ICU stay. Sixty-four patients were analyzed, with median age of 39 years (interquartile range ITQ: 28-53) and 66% were male. Median burned body surface area was 30% (ITQ: 20-46). Twenty-eight (56%) patients presented criteria for IAH and seven (14%) developed clinical signs compatible with ACS. Burn severity was greater in the group that developed IAH, represented by the ABSI score. This group also presented higher values of creatinine and positive fluid balance. The group of patients with ACS showed a higher frequency of alterations in renal and respiratory functions. The organ systems most frequently affected in groups with diagnostic criteria for IAH and ACS were renal, cardiovascular and respiratory. Mortality rate at hospital outcome was 56%. In conclusion, the incidence of IAH during the study period was high in patients with extensive burns. The occurrence of ACS was associated with organic dysfunctions of the respiratory, cardiovascular and renal systems. The factors associated with intra-abdominal hypertension were age, extension of burned body surface, inhalation injury, and need for mechanical ventilation.


Cette étude a pour objectifs d'analyser l'incidence de l'hyperpression abdominale (HPA) et du syndrome du compartiment abdominal (SCA) chez les brûlés graves. Il s'agit d'une étude monocentrique prospective conduite auprès des 64 patients admis avec une brûlure >20% SCT entre août 2015 et janvier 2018. La préssion intraabdominale (PIA) était régulièrement mesurée pendant la première semaine. L'âge médian des patients était de 39 ans (IQR 28-53) et les 2/3 d'entre eux étaient des hommes. La SCT médiane était de 30% (IQR 20-46). Vingt huit (56%) patients avaient des critères d'HPA et 7 (14%) ont présenté des signes de SCA. Le score ABSI et la créatininémie étaient plus élevés chez les patients avec HPA, qui avaient aussi un bilan entrées-sorties positif. Les patients avec un SCA avaient plus de défaillances rénale et respiratoire. Les défaillances les plus fréquemment observées chez les patients avec HPA/SCA étaient rénales, cardio-vasculaires et respiratoires. La mortalité était de 56%. En conclusion, l'incidence de HPA est élevée chez les patients gravement brûlés. La survenue de SCA est une cause de défaillances rénale, cardio-vasculaire et respiratoire. Les facteurs prédicitifs de HPA étaient l'âge, la surface brûlée, l'inhalation de fumées et le recours à la ventilation mécanique.

RESUMO

New benz[alpha]anthraquinone antibiotics (brasiliquinones A, B and C) with an ethyl group at C-3 were isolated. The producer was identified as Nocardia brasiliensis. The antibiotics were active against Gram-positive bacteria including Mycobacterium sp., but not active against Gram-negative bacteria or fungi. They were also active against multiple drug-resistant P388/ADR tumor cells.
