Analysis of Incidence, Risk Factors and Outcomes Associated With Abdominal Hypertension in Major Burn Patients.

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.

Infectious complications in adult burn patients and antimicrobial resistance pattern of microorganisms isolated.

The objective of this study was to analyze the incidence of hospital acquired infections (HAIs) in burn patients, and to determine the principle infection sites and the sensitivity profile of the microorganisms to antimicrobials. This is a retrospective cohort study, conducted in a specialized centre for the treatment of burns from January 2009 to December 2013. The sample consisted of 404 patients, divided into two groups: the first group comprised 142 patients without infection, and the second group was made up of 262 patients who had acquired HAIs. There was a predominance of males in both groups. Mean age of the patients without infection was 37 years (SD 14.89), and 38 years (SD 15.78) for the patients with HAIs. Of the 523 infections observed in this study, pneumonia was the most frequent with 216 (41%) cases, followed by urinary tract infections with 137 (26%) episodes. The pathogens identified were Acinetobacter baumannii (93, 40%), Pseudomonas aeruginosa (50, 21%) and Klebsiella (pneumoniae/oxytoca) (23, 10%) and were resistant to most common antimicrobials. In the study population, no pathogens resistant to vancomycin were found. The present study describes high rates of infection in burn victims. Pneumonia was the most frequent site of infection, followed by urinary tract infections caused respectively by non-fermenting bacteria with a high frequency of antimicrobial resistance.

L'objectif de cette étude était d'analyser l'incidence des infections nosocomiales chez les patients brûlés, de déterminer les principaux sites infectés et d'analyser les profils de sensibilité des bactéries. Cette étude rétrospective a été conduite dans un CTB entre janvier 2009 et décembre 2013. L'échantillon de 404 patients a été réparti en 2 groupes: le premier, de 142 patients, sans infection (SI) et le second de 262 patients infectés (I). Les hommes prédominaient dans les 2 groupes. L'âge moyen des patients SI était de 37 +/- 14,89 ans, celui des patients I de 38 +/- 15,78 ans. Les 216 pneumonies représentaient la majorité (41%) des 523 infections relevées, suivies par les infections urinaires (137, 26%). Acinetobacter baumannii (93 isolats; 40%), Pseudomonas æruginosa (50; 21%) et Klebsiella sp. (23; 10%) étaient les plus fréquents et les plus résistants. Nous n'avons pas isolé de bactérie VAN R. On constate une prévalence élevée des infections chez les brûlés, principalement en sites pulmonaire et urinaire, souvent par des BGN non fermentants à résistance élevée.

The epidemiology of sepsis in a Brazilian teaching hospital.

OBJECTIVES: The objective of this study was to estimate disease incidence and mortality rate of sepsis in a tertiary public hospital. METHODS: Patients admitted to the Intensive Care Unit (ICU) in 2004 and 2005 were monitored for sepsis using an observational longitudinal study design. Patients were monitored daily for diagnostic criteria of sepsis, according to ACCP/SCCM Consensus Conference criteria, until either death or hospital discharge. RESULTS: During the study, we analyzed 1,179 patients. Systemic Inflammatory Response Syndrome (SIRS) was present in 1,048 (88.9%) patients on admission, and was associated with infection in 554 (47.0%) patients. Of these, sepsis was diagnosed in 30 (2.5%) patients, while severe sepsis was diagnosed in 269 (22.8%) patients, and septic shock was diagnosed in 255 (21.6%) patients. APACHE II and SOFA scores were higher in septic patients (p < 0.001), and the ensuing mortality rates were 32.8% (IC 95%: 21.6-45.7%) for patients with sepsis, 49.9% (IC 95%: 44.5-55.2%) for severe sepsis, and 72.7% (IC 95%: 68.1-76.9%) for septic shock. CONCLUSIONS: The data from our study revealed a high incidence of sepsis among hospitalized patients. Moreover, sepsis patients had a high rate of mortality.
