Ultrasound-based clinical profiles for predicting the risk of intradialytic hypotension in critically ill patients on intermittent dialysis: a prospective observational study.

BACKGROUND: Intradialytic hypotension, a complication of intermittent hemodialysis, decreases the efficacy of dialysis and increases long-term mortality. This study was aimed to determine whether different predialysis ultrasound cardiopulmonary profiles could predict intradialytic hypotension. METHODS: This prospective observational single-center study was performed in 248 critically ill patients with acute kidney injury undergoing intermittent hemodialysis. Immediately before hemodialysis, vena cava collapsibility was measured by vena cava ultrasound and pulmonary congestion by lung ultrasound. Factors predicting intradialytic hypotension were identified by multiple logistic regression analysis. RESULTS: Intradialytic hypotension was observed in 31.9% (n = 79) of the patients, interruption of dialysis because of intradialytic hypotension occurred in 6.8% (n = 31) of the sessions, and overall 28-day mortality was 20.1% (n = 50). Patients were classified in four ultrasound profiles: (A) 108 with B lines > 14 and vena cava collapsibility > 11.5 mm m-2, (B) 38 with B lines < 14 and vena cava collapsibility ≤ 11.5 mm m-2, (C) 36 with B lines > 14 and vena cava collapsibility Di ≤ 11.5 mm m-2, and (D) 66 with B lines < 14 and vena cava collapsibility > 11.5 mm m-2. There was an increased risk of intradialytic hypotension in patients receiving norepinephrine (odds ratios = 15, p = 0.001) and with profiles B (odds ratios = 12, p = 0.001) and C (odds ratios = 17, p = 0.001). CONCLUSION: In critically ill patients on intermittent hemodialysis, the absence of hypervolemia as assessed by lung and vena cava ultrasound predisposes to intradialytic hypotension and suggests alternative techniques of hemodialysis to provide better hemodynamic stability.

Clinical impact of sepsis at admission to the ICU of a private hospital in Salvador, Brazil.

OBJECTIVE: To describe the clinical characteristics, laboratory data, and clinical outcomes of patients with and without sepsis admitted to the ICU of a private hospital in the city of Salvador, Brazil, and to identify clinical variables related to a worse prognosis in those with sepsis. METHODS: This was a longitudinal study including all patients admitted to the general ICU of the Hospital Português, in the city of Salvador, Brazil, between June of 2008 and March of 2009. At ICU admission, two groups of patients were identified: with sepsis and without sepsis. Epidemiological, clinical and laboratory data were collected, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score was calculated. RESULTS: Of the 144 patients in the study, 29 (20.1%) had sepsis. Among the patients with sepsis, males accounted for 55.2%, the mean age was 73.1 ± 14.6 years, and the mean APACHE II score was 23.8 ± 9.1, compared with 36.3%, 68.7 ± 17.7 years, and 18.4 ± 9.5, respectively, among those without sepsis. There were significant associations between a diagnosis of sepsis and the following variables: APACHE II score; in-hospital mortality; ICU mortality; HR; mean arterial pressure; hematocrit level; white blood cell count; and antibiotic use. The use of life support measures and lower hematocrit levels were associated with a worse prognosis in the patients with sepsis. CONCLUSIONS: The patients diagnosed with sepsis presented worse clinical outcomes, probably due to their greater severity. Hematocrit level was the only variable that was a predictor of mortality risk in the patients with sepsis.

Impacto clínico do diagnóstico de sepse à admissão em UTI de um hospital privado em Salvador, Bahia / Clinical impact of sepsis at admission to the ICU of a private hospital in Salvador, Brazil

OBJETIVO: Descrever as características clínicas, os dados laboratoriais e o desfecho clínico de pacientes sépticos e não sépticos admitidos em UTI de um hospital privado na cidade de Salvador, Bahia, e identificar variáveis clínicas relacionadas ao pior prognóstico dos pacientes sépticos. MÉTODOS: Foi realizado um estudo longitudinal que incluiu todos os pacientes admitidos na UTI geral do Hospital Português, Salvador (BA), entre junho de 2008 e março de 2009. Na admissão na UTI, dois grupos de pacientes foram identificados: sépticos e não sépticos. Foram coletados dados epidemiológicos, clínicos e laboratoriais, e o escore Acute Physiology and Chronic Health Evaluation II (APACHE II) foi calculado. RESULTADOS: Dos 144 pacientes do estudo, 29 (20,1 por cento) eram sépticos. Entre os pacientes sépticos, 55,2 por cento eram do sexo masculino, a média de idade foi de 73,1 ± 14,6 anos, e a média do escore do APACHE II foi de 23,8 ± 9,1. No grupo não séptico, 36,3 por cento eram do sexo masculino, a média de idade foi de 68,7 ± 17,7 anos, e a média do escore do APACHE II foi de 18,4 ± 9,5. Houve associações estatisticamente significantes entre o diagnóstico de sepse e as seguintes variáveis: escore do APACHE II, mortalidade na UTI, mortalidade hospitalar, FC, pressão arterial média, valor de hematócrito, contagem de leucócitos e uso de antibioticoterapia. O uso de medidas de suporte e valores reduzidos de hematócrito se relacionaram com um pior prognóstico entre os pacientes sépticos. CONCLUSÕES: Os pacientes diagnosticados com sepse apresentaram piores desfechos clínicos, provavelmente por causa de sua maior gravidade. O nível de hematócrito foi a única variável capaz de predizer o risco de morte entre pacientes sépticos.

Análise da satisfação dos familiares em unidade de terapia intensiva / Analysis of family satisfaction in intensive care unit

OBJETIVOS: Conhecer as necessidades e o grau de satisfação dos familiares de pacientes internados em unidades de terapia intensiva é uma parte essencial dos cuidados dos profissionais de saúde. O objetivo deste trabalho foi identificar o grau de satisfação dos familiares de pacientes internados em unidades de terapia intensiva. MÉTODOS: Foi realizado um estudo descritivo na unidade de terapia intensiva Geral Adulto do Hospital Português (Salvador-BA) durante o período de novembro de 2007 a janeiro de 2008. Para avaliação da satisfação dos familiares foi utilizada a versão modificada por Jonhson (1998) do Inventário de Necessidades de Familiares em Terapia Intensiva . RESULTADOS: Foram avaliados 53 familiares, com média de idade de 44 anos, sendo 68 por cento do sexo feminino. A mediana do nível de satisfação dos familiares foi de 11 (IIQ:9-13), numa escala de um a quatorze. As questões do Inventário de Necessidades de Familiares em Terapia Intensiva com maiores índices de satisfação foram as que afirmavam que os familiares sentiam que o melhor cuidado possível estava sendo oferecido ao paciente (96 por cento) e que as informações dadas foram honestas (96 por cento). As questões com índices menores de satisfação foram as que afirmavam que os familiares acreditavam que alguém da unidade de terapia intensiva demonstrou interesse em saber como estavam se sentindo (45 por cento) e que os funcionários do hospital explicaram como os equipamentos estão sendo usados (41 por cento). CONCLUSÕES: A maioria dos familiares avaliou positivamente os profissionais da unidade de terapia intensiva nas questões relacionadas à comunicação, atitude e cuidado médico com o paciente. No entanto, houve um percentual menor de satisfação nas questões relacionadas com a capacidade dos profissionais de confortar os familiares.

OBJECTIVES: To know the needs and level of family members' satisfaction is an essential part of the care provided to critically ill patients in intensive care units. The objective of this study was to identify the level of family members' satisfaction in an intensive care unit. METHODS: A descriptive survey was carried out in the general adult intensive care unit of the Hospital Português (Salvador - BA) from November 2007 to January 2008. Jonhson's 14-question modified version of the Critical Care Family Needs Inventory was used to evaluate satisfaction of family members. RESULTS: Fifty three family members were included, mean age was 44 years and 68 percent were female. The median of family members satisfaction level was 11 (IQI = 9-13). Critical Care Family Need Inventory, questions with higher percentiles of satisfaction were those stating that family members felt that the patient was receiving the best possible care (96 percent) and that the information provided was honest (96 percent). The questions with lower percentiles of satisfaction were those stating that family members believed that someone in the intensive care unit had shown interest in their feelings (45 percent) and that a healthcare professional had explained how the intensive care unit equipment was used (41 percent). CONCLUSIONS: Most family members positively evaluated the intensive care unit professionals in the questions related to communication, attitude and patient care. However, there was a lower level of satisfaction in the questions related to the intensive care unit professionals' ability to comfort family members.

Funçäo pulmonar na gravidez: o volume de isofluxo no último trimestre de gestaçäo / Pulmonary function in pregnancy: isoflow volume in the last trimester of pregnancy

A funçäo pulmonar foi testada em dezoito mulheres sadias näo-fumantes, no último trimestre da gestaçäo e em nove controles. A funçäo das vias aéreas periféricas foi enfatizada tendo sido avaliada através da determinaçäo do volume de isofluxo. Constatou-se discreta reduçäo da capacidade vital, ao passo que a capacidade residual funcional esteve bastante diminuída. O volume de isofluxo manteve-se dentro dos valores normais para ambos os grupos, sugerindo que o comportamento dos pequenos brônquios é normal nesta fase da gestaçäo
