The use of perioperative serial blood lactate levels, the APACHE II and the postoperative MELD as predictors of early mortality after liver transplantation
Why the surgical patients are so critical in their intensive care unit arrival? Porque os pacientes cirúrgicos chegam em estado tão crÃtico na unidade de terapia intensiva?
PURPOSE: To assess the ability of the Acute Physiology and Chronic Health Evaluation II (APACHE II) to stratify the severity of illness and the impact of delay transfer to an Intensive Care Unit (ICU) on the mortality of surgical critically ill patients. METHODS: Five hundred and twenty-nine patients (60.3% males and 39.7% females; mean age of 52.8 ± 18.5 years) admitted to the ICU were retrospectively studied. The patients were divided into survivors (n=365) and nonsurvivors (n=164). APACHE II and death risk were analysed by generation of receiver operating characteristic (ROC) curves. The interval time between referral and ICU arrival was also registered. The level of significance was 0.05. RESULTS: The mean APACHE II and death risk was 19.9 ± 9.6 and 37.7 ± 28.9%, respectively. The area under the ROC curve for APACHE II and death risk was 0.825 (CI = 0.765-0.875) and 0.803 (CI = 0.741-0.856). The overall mortality (31%) increased progressively with the delay time to ICU transfer, as also evidencied by the APACHE II score and death risk. CONCLUSION: This investigation shows that the longer patients wait for ICU transfer the higher is their criticallity upon ICU arrival, with an obvious negative impact on survival rates.<br>OBJETIVO: Investigar a habilidade do Acute Phisiologic and Chronic Health Evaluation II (APACHE II) na estratificação da gravidade e o impacto causado pelo tempo de transferência para a unidade de terapia intensiva (UTI) sobre a mortalidade de pacientes cirúrgicos em estado crÃtico. MÉTODOS: Foram estudados retrospectivamente 529 pacientes (60,3% homens e 39,7% mulheres, média de idade = 52,8 ± 18,5 anos) admitidos na UTI, divididos em sobreviventes (n=365) e não sobreviventes (n=164). O APACHE II e o risco de óbito (RO) foram analisados por curvas ROC (Receiver Operating Characteristics). O tempo decorrido entre a solicitação da vaga e a chegada do paciente na UTI foi verificado. Considerou-se um nÃvel de significância de 0,05. RESULTADOS: O APACHE II e o risco de óbito foram de 19,9 ± 9,6 e 37,7 ± 28,9%, respectivamente. A área sob a curva ROC para o APACHE II foi de 0,825 (IC = 0,765-0,875) e para o RO de 0,803 (IC = 0,741-0,856). A mortalidade geral (31%) cresceu progressivamente com o tempo decorrido entre a solicitação da vaga e a chegada do paciente na UTI, também evidenciado pelo APACHE II e o risco de óbito. CONCLUSÃO: Esta investigação mostra que quanto maior é a demora na transferência do paciente para a UTI mais aumenta a gravidade dos pacientes, cujo impacto na sobrevida é negativo
The use of perioperative serial blood lactate levels, the APACHE II and the postoperative MELD as predictors of early mortality after liver transplantation O uso da dosagem seriada do lactato sérico no perioperatório, do APACHE II e do MELD pós-operatório como preditores de mortalidade precoce após transplante hepático
PURPOSE: To evaluate the accuracy of different parameters in predicting early (one-month) mortality of patients submitted to orthotopic liver transplantation (OLT). METHODS: This is a retrospective study of forty-four patients (38 males and 10 females, mean age of 52.2 ± 8.9 years) admitted to the Intensive Care Unit of a tertiary hospital. Serial lactate blood levels, APACHE II, MELD post-OLT, creatinine, bilirubin and INR parameters were analyzed by receiver-operator characteristic (ROC) curves as evidenced by the area under the curve (AUC). The level of significance was set at 0.05. RESULTS: The mortality of OLT patients within one month was 17.3%. Differences in blood lactate levels became statistically significant between survivors and nonsurvivors at the end of the surgery (p<0.05). The AUC was 0.726 (95%CI = 0.593-0.835) for APACHE II (p = 0.02); 0.770 (95%CI = 0.596-0.849) for blood lactate levels (L7-L8) (p = 0.03); 0.814 (95%CI = 0.690-0.904) for MELD post-OLT (p < 0.01); 0.550 (95%CI = 0.414-0.651) for creatinine (p = 0.64); 0.705 (95%CI = 0.571-0.818) for bilirubin (p = 0.05) and 0.774 (95%CI = 0.654-0.873) for INR (p = 0.02). CONCLUSION: Among the studied parameters, MELD post-OLT was more effective in predicting early mortality after OLT.<br>OBJETIVO: Avaliar qual parâmetro é o mais eficiente na predição de mortalidade precoce (um mês) de pacientes submetidos a transplante ortotópico de fÃgado (OLT). MÉTODOS: Estudo retrospectivo em cinqüenta e oito pacientes adultos (44 homens e 14 mulheres, com uma idade média de 51,7 ± 10,1 anos) admitidos na Unidade de Terapia Intensiva de um hospital terciário. Os parâmetros como a dosagem seriada de lactato no sangue, APACHE II, MELD pós-OLT, creatinina, bilirrubina e INR foram analisados por curvas ROC (Receiver-operator characteristic), evidenciado pela área abaixo da curva (AUC). O nÃvel de significância foi definido em 0,05. RESULTADOS: A mortalidade dos pacientes OLT em até um mês foi de 17,3%. As diferenças no nÃvel de lactato no sangue tornaram-se estatisticamente significantes entre sobreviventes e não sobreviventes no final da cirurgia (p < 0,05). A AUC foi de 0,726 (95%CI = 0,593-0,835) para APACHE II (p = 0,02); 0,770 (95%CI = 0,596-0,849) para o lactato sérico (L7-L8) (p = 0,03); 0,814 (95%CI = 0,690-0,904) para MELD post-OLT (p < 0,01); 0,550 (95%CI = 0,414-0,651) de creatinina (p = 0,64); 0,705 (95%CI = 0,571-0,818) de bilirrubina (p = 0,05) e 0,774 (95%CI = 0,654-0,873) para INR (p = 0,02). CONCLUSÃO: Dentre os vários parâmetros estudados, o MELD pós-OLT foi o mais eficaz na predição de mortalidade precoce em pacientes submetidos à OLT

Ribeirão Preto, SP, BrasilVentilator-associated pneumonia (VAP) remains one of the major causes of infection in the intensive care unit (ICU) and is associated with the length of hospital stay, duration of mechanical ventilation, and use of broad-spectrum antibiotics. We compared the frequency of VAP 10 months prior to (pre-intervention group) and 13 months after (post-intervention group) initiation of the use of a heat and moisture exchanger (HME) filter. This is a study with prospective before-and-after design performed in the ICU in a tertiary university hospital. Three hundred and fourteen patients were admitted to the ICU under mechanical ventilation, 168 of whom were included in group HH (heated humidifier) and 146 in group HME. The frequency of VAP per 1000 ventilator-days was similar for both the HH and HME groups (18.7 vs 17.4, respectively; P = 0.97). Duration of mechanical ventilation (11 vs 12 days, respectively; P = 0.48) and length of ICU stay (11 vs 12 days, respectively; P = 0.39) did not differ between the HH and HME groups. The chance of developing VAP was higher in patients with a longer ICU stay and longer duration of mechanical ventilation. This finding was similar when adjusted for the use of HME. The use of HME in intensive care did not reduce the incidence of VAP, the duration of mechanical ventilation, or the length of stay in the ICU in the study population
Septic shock caused by Plesiomonas shigelloides in a patient with sickle beta-zero thalassemia
Invasive infection and extraintestinal complications are rarely caused by Plesiomonas shigelloides, a water-borne bacterium belonging to the Vibrionaceae family. We report a case of a 16-year-old female patient with sickle beta-zero thalassemia who survived septic shock caused by P. shigelloides associated with secondary acute respiratory distress syndrome and disseminated intravascular coagulation. Treatment with a carbapenem was successful, and the patient recovered without any sequelae. The previous reports of P. shigelloides sepsis are cited, and possible pathogenic mechanisms are discussed.
