STUDY OBJECTIVE: Obese patients seem to have worse outcomes and more complications during intensive care unit (ICU) stay. This study describes the clinical course, complications and prognostic factors of obese patients admitted to an intensive care unit compared to a control group of nonobese patients. DESIGN: Retrospective observational study. SETTING: A 10-bed adult intensive care unit in a university-affiliated hospital. METHODS: All patients admitted to the intensive care unit over 52 months (April 01/2005 to November 30/2008) were included. Obese patients were defined as those with a body mass index (BMI) ≥ 30 Kg/M2. Demographic and intensive care unit related data were also collected. An clinical and demographical matching group of eutrophic patients selected from the data base as comparator for mortality and morbidity outcomes. The Mann-Whitney test was used for numeric data comparisons and the Chi Square test for categorical data comparisons. RESULTS: Two hundred nineteen patients were included. The obese group (n=73) was compared to the eutrophic group (n= 146). Most of this group BMI ranged between 30 - 35 Kg/M2. Only ten patients had body mass index ≥40 Kg/M2. Significant differences between the obese and eutrophic groups were observed in median APACHE II score (16 versus 12, respectively; p<0.05) and median intensive care unit length of stay (7 versus 5 days respectively; p<0,05). No significant differences were seen regarding risk of death, mortality rate, mechanical ventilation needs, days free of mechanical ventilation and tracheostomy rates. The observed mortality was higher than the APACHE II-predicted for both groups, but the larger differences were seen for morbid obese patients (BMI ≥40 Kg/M2). CONCLUSIONS: Obesity did not increase the mortality rate, but improved intensive care unit length of stay. The current prognostic scoring systems do not include BMI, possibly underestimating the risk of death, and other quality of care indexes in obese patients. New studies could be useful to clarify how body mass index impacts the mortality rate.

BACKGROUND: The elderly population is increasing all over the world. The need of intensive care by the elderly is also increasing. There is a lack of studies investigating the risk factors for death among critically ill elderly patients. This study aims to investigate the factors associated with death in a population of critically ill elderly patients admitted to an intensive care unit in Brazil. METHODS: This is a retrospective cohort study including all elderly patients (>60 years) admitted to an intensive care unit in Fortaleza, Brazil, from January to December 2007. A comparison between survivors and nonsurvivors was done and the risk factors for death were investigated through univariate and multivariate analysis. RESULTS: A total of 84 patients were included, with an average age of 73 ± 7.6 years; 59% were female. Mortality was 62.8%. The main cause of death was multiple organ dysfunction (42.3%), followed by septic shock (36.5%) and cardiogenic shock (9.7%). Complications during intensive care unit ICU stay associated with death were respiratory failure (OR=61, p<0.001), acute kidney injury (OR=23, p<0.001), sepsis (OR=12, p<0.001), metabolic acidosis (OR=17, p<0.001), anemia (OR=8.6, p<0.005), coagulation disturbance (OR=5.9, p<0.001) and atrial fibrillation (OR=4.8, p<0.041). Independent risk factors for death were age (OR=1.15, p<0.005), coma (OR=7.51, p<0.003), hypotension (OR=21.75, p=0.003), respiratory failure (OR=9.93, p<0.0001) and acute kidney injury (OR=16.28, p<0.014). CONCLUSION: Mortality is high among critically ill elderly patients. Factors associated with death were age, coma, hypotension, respiratory failure and acute kidney injury.

OBJECTIVE: To identify risk factors associated with death of infants admitted to neonatal intensive care unit of Taubaté University Hospital. METHODS: It is a longitudinal study with information obtained from medical records of newborns admitted to the neonatal intensive care unit of Taubaté University Hospital. Type of outcome, discharge or death, was dependent variable. The independent variables were maternal and gestational variables: maternal age, hypertension, diabetes, corticosteroid therapy and delivery; variables of the newborn: birth weight, gestation length, Apgar score in the first and fifth minutes of life, multiple birth, congenital malformations and sex; hospitalar variables: report of mechanical ventilation, positive pressure ventilation, reports of prolonged parenteral nutrition, sepsis, intubation, cardiac massage, phototherapy, hyaline membrane disease, oxygen and fraction of inspired oxygen. It was built a model in three hierarchical levels for the survival analysis by the Cox model; it was used the software Stata v9 and the final model contained variables with p <0.05. The risks were estimated by measure effect known as hazard ratio (HR) with confidence intervals of 95%. The newborns transferred during hospitalization to another service were excluded from the study. RESULTS: There were admitted during the study period 495 newborns, with 129 deaths (26.1%). In the final model, only the variables of steroid use (HR 1.64, 95% CI 1.02-2.70), malformation (HR 1.93, CI 95% 1,05-2,88), very low birth weight (HR 4.28, 95% CI 2,79-6,57) and Apgar scores lower than seven of no1 min (HR 1.87, 95% CI 1,19-2,93) and 5 min (HR 1.74, 95% CI 1,05-2,88) and the variables phototherapy (HR 0.34; 95% CI 0,22-0,53) and endotracheal intubation (HR 2.28, 95% CI 1 .41-3, 70). CONCLUSION: Factors related primarily to the newborn and the hospitalar internment (except therapy with corticosteroids) were identified as associated to mortality highlighting a possible protective factor of phototherapy and the risk of infants with very low birth weight.

OBJECTIVE: To verify if the maximal inspiratory pressure values with 40 seconds occlusion time are greater than with the 20 seconds occlusion time, and the impacts on the following patient's physiological variables: respiratory rate, pulse oxygen saturation, heart rate and blood pressure, before and after the measurements. METHODS: This was a transversal prospective randomized study. Fifty-one patients underwent maximal inspiratory pressure measurement, measured by one single investigator. The manometer was calibrated before each measurement, and then connected to the adapter and this to the unidirectional valve inspiratory branch for 20 or 40 seconds. RESULTS: The values with 40 seconds occlusion (57.6 ± 23.4 cmH2O) were significantly higher than the measurements taken with 20 seconds occlusion (40.5 ± 23.4 cmH2O; p=0.0001). The variables changes between the before and after measurement respiratory and hemodynamic parameters monitoring showed: heart rate variation for the 20 seconds occlusion 5.13 ± 8.56 beats per minute and after 40 seconds occlusion 7.94 ± 12.05 beats per minute (p = 0.053), versus baseline. The mean blood pressure change for 20 seconds occlusion was 9.29 ± 13.35 mmHg and for 40 seconds occlusion 15.52 ± 2.91 mmHg (p=0.021). The oxygen saturation change for 20 seconds occlusion was 1.66 ± 12.66%, and for 40 seconds 4.21 ± 5.53% (p=0.0001). The respiratory rate change for 20 seconds occlusion was 6.68 ± 12.66 movements per minute and for 40 seconds 6.94 ± 6.01 (p=0.883). CONCLUSION: The measurement of maximal inspiratory pressure using a longer occlusion (40 seconds) produced higher values, without triggering clinically significant stress according to the selected variables.

Post-traumatic stress disorder has been detected in patients after treatment in intensive care unit. The main goal of this study is to review the psychological aspects and therapeutic interventions on those patients after their treatment on intensive care unit. Thirty eight articles have been included. The prevalence of post-traumatic stress disorder has varied from 17% up to 30% and the incidence from 14% to 24%. The risk factors were: previous anxiety historic, depression or panic, having delusional traumatic memories (derived from psychic formations as dreams and delirium), belief effects, depressive behavior, stressing experiences and mechanical ventilation. High doses of opiates, symptoms caused by sedation or analgesia reduction and the use of lorazepam were related with the increase of delirium and delusional memory. The disorder sintomatology can be reduced with hydrocortisone administration, with daily sedation interruption. No other effectiveness psychological intervention study was found.

OBJECTIVE: This study aimed to evaluate the outcome of cirrhotic patients admitted to Intensive Care Unit. METHODS: We conducted a prospective cohort of cirrhotic patients admitted to two intensive care unit between June 1999 to September 2004. We collected demographic, comorbid conditions, diagnosis, vital signs, laboratory data, prognostic scores and evolution in intensive care unit and hospital. The patients were divided in groups: non surgical, non liver surgery, surgery for portal hypertension, liver surgery, liver transplantation, and urgent surgery. RESULTS: We studied 304 patients, which 190 (62.5%) were male. The median of age was 54 (47-61) years. The mortality rate in intensive care unit and hospital were 29.3 and 39.8%, respectively, more elevated than in the other patients admitted critically ill patients (19.6 and 28.3%; p<0.001). Non surgical patients and those submitted to urgent surgery presented high mortality rate in the intensive care unit (64.3 and 65.4%) and in the hospital (80.4 and 76.9%). The variables related to hospital mortality were [Odds ratio (confidence interval 95%)]: mean arterial pressure [0.985 (0.974-0.997)]; mechanical ventilation in the first 24 h [4.080 (1.990-8.364)]; confirmed infection in the first 24 h [7.899 (2.814-22.175)]; acute renal failure [5.509 (1.708-17.766)] and APACHE II score (points) [1.078 (1.017-1.143)]. CONCLUSIONS: Cirrhotic patients had higher mortality rate compared to non cirrhotic critically ill patients. Those admitted after urgent surgery and non surgical had higher mortality rate.

OBJECTIVE: To correlate the RIFLE classification with mortality and length of stay both in the intensive care unit and hospital. METHODS: A prospective, observational, longitudinal cohort study, approved by the Institution's Ethics Committee. Data were collected for all patients staying longer than 24 hours in the intensive care unit of Hospital Universitário Polydoro Ernani de São Thiago - Universidade Federal de Santa Catarina from September 2007 to March 2008, followed-up either until discharge or death. Patients were divided in two groups: with or without acute kidney injury. The acute kidney injury group was additionally divided according to the RIFLE and sub-divided according to the maximal score in Risk, Injury of Failure. Loss and End-stage classes were not included in the study. APACHE II and SOFA were also evaluated. The t Student and Chi-Square tests were used. A P<0.05 was considered statistically significant. RESULTS: The sample included 129 patients, 52 (40.3%) with acute kidney injury according to RIFLE. Patients were more severely ill in this group, with higher APACHE and SOFA scores (P<0.05). Compared to the without kidney injury group, the kidney injury severity caused increased intensive care unity (Risk 25%; Injury 37.5%; Failure 62.5%) and in-hospital (Risk 50%; Injury 37.5%; Failure 62.5%) mortality, and longer intensive care unit stay (P<0.05). CONCLUSION: The RIFLE system, according to the severity class, was a marker for risk of increased intensive care unit and in-hospital mortality, and longer intensive care unit stay. No relationship with in-hospital length of stay was found.

BACKGROUND: The anemia is a common problem upon admission of the patients in the intensive care unit being the red blood cell transfusion a frequent therapeutic. The causes of anemia in critical patients who under go red blood cell transfusion are several: acute loss of blood after trauma, gastrointestinal hemorrhage, surgery amongst others. Currently, few studies are available regarding the use of blood components in patients at intensive care unit. Although blood transfusions are frequent in intensive care unit, the optimized criteria for handling are not clearly defined, with no available guidelines. OBJECTIVES: To analyze the clinical indications of the use of the red blood cell in the intensive care unit. METHODS: The clinical history of the patients admitted in the intensive care unit were analyzed, revisiting which had have red blood cell transfusion in the period between January 1st 2005 and December 31 2005. The study was accepted by the Research Ethics Committee - Comitê de Ética em Pesquisa (CEP) - of the University of South of Santa Catarina (UNISUL). RESULTS: The transfusion rate was 19,33, and the majority of the patients were of the male gender. Their age prevalence was of 60 years old or older. The mortality rate among patients who under went red blood cell transfusion died was of 38,22%. The transfusions criterias were low serum hemoglobin (78%) and the hemoglobin pre - transfusion was 8,11 g/dL. CONCLUSIONS: Politrauma and sepsis/sepsis chock were the pre diagnosis criteria. A low hemoglobin level is the main clinical criteria with average hemoglobin pre - transfusion was 8,11 g/dL.
