BACKGROUND AND OBJECTIVES: This study is a case report of a patient that was submitted to implant of enteric tube (ET) in the ICU, being evidenced false passage in proximal esophagus during endoscopic procedure, demonstrating tunnel for the submucosa. CASE REPORT: A 77 years old woman, transferred to ICU, where ET was installed (due to difficulty of being carried through both nostrils) being confirmed its position through thoraco-abdominal x-ray. The patient remained around 10 days with the ET, receiving diet, without any alteration. In the 10th day she was evolved with melena and reduction of the values of Hb/Ht, without hemodynamic repercussion. Submitted to the high digestive endoscopic that evidenced ulcer injury to bulbar, of about 2.5 cm, with signals of former bleeding. During the examination, a false passage of the ET in proximal esophagus was visualized: 2 cm below of the crico-faring, tunnel for the submucosa possibly for all above-mentioned segments, following its habitual passage until gastric chamber. CONCLUSIONS: Patients of high risk for esophagus perforation for ET installation can be identified and well-taken care of adjusted they can be used. If to occur perforation, this must be identified how much so early possible, for adequate treatment. The adequate treatment depends of each case and same the clinical therapy can be appropriate in selected cases.

BACKGROUND AND OBJECTIVES: The aim of this study was to analyze the morbidity and the mortality of critically ill patients admitted to the intensive care unit in a teaching hospital, using the APACHE II score. METHODS: Descriptive and retrospective study, with analysis of 300 patients admitted to ICU from March 2004 to July 2005. RESULTS: Of the 300 patients admitted to ICU, 51.7% were men, average 54.2 ± 19.57 years and 78% from the wards of the teaching hospital itself. There was more prevalence of patients aged 60 years or older (43%). The main dysfunctions were from the respiratory and cardiocirculatory systems. Length of stay in ICU was 7.51 ± 8.21 days. The mean of APACHE II was 16.48 ± 7.67, with meaningful difference between survivors and deceased patients. The real mortality rate in ICU was 32.7%, without meaningful difference between patients that died before or after 48 hours. The standardized mortality ratio was 1.1. CONCLUSIONS: Despite the severity of the patients admitted to ICU, the standardized mortality ratio suggests a satisfactory quality in the service.

BACKGROUND AND OBJECTIVES: To correlate standard base excess (SBE) with serum lactate level and demonstrate the independent prognostic significance of each one. METHODS: In a retrospective study, we retrieved data from 333 patients of our prospectively collected database of 7-bed medical intensive care unit of a 1800-bed university hospital. RESULTS: The results have shown a poor correlation between SBE and lactate, r = - 0.358, p < 0.001, and an independent prognostic significance of each one when analyzed concomitantly, odds ratio (95% Confidence interval) = 0.996 (0.992 - 0.999) to standard base excess and 1.000 (1.000 - 1.002) to lactate at entrance; and odds ratio (95% Confidence interval ) = 0.990 (0.985 - 0.994) to standard base excess and 1.003 (1.001 - 1.005) to lactate after 24 hours. The accuracy of standard base excess was close to lactate to determine in-intensive care unit death. CONCLUSIONS: The lactic component of the metabolic acidosis is not the major determinant of standard base excess. Serum lactate and SBE are independent outcome predictors in critically ill patients.

BACKGROUND AND OBJECTIVES: Nosocomial infection represents a challenge in clinical practice involving hospitalized patients, as they considerably extend the hospitalization period and morbidity and mortality rates and, at the same time, increase hospital costs. Given their clinical conditions, which require invasive procedures and antimicrobial treatment, hospitalized patients, especially at the Intensive Care Unit, are particularly susceptible to hospital infection. This study aimed to evaluate the occurrence of multiresistant bacteria in patients hospitalized at the Intensive Care Unit of a Brazilian emergency hospital. METHODS: Our retrospective study was approved by the Ethics Committee and considered the period between October 2003 and September 2004. A database was developed through variable coding and double entry, and Statistical Package for Social Sciences (SPSS) software, version 10.0, was used for statistical analysis. RESULTS: Multiresistant bacteria were identified in 68 patients, 47 (69.1%) of whom were men, with 55 years as the mean age. All patients were submitted to endotracheal intubation and central venipuncture. The most frequent bacteria were coagulase-negative Staphylococcus sp. (36.4%), followed by Staphylococcus aureus (19%). Cephalosporin was the most frequently used (21.4%) antimicrobial agent. CONCLUSIONS: Knowledge on infection occurrence provokes reflections on multiresistance, directs educative actions and favors interventions to prevent and control problem situations.

BACKGROUD AND OBJECTIVES: The high frequency oral oscillation therapy (HFOO) is carried through a plastic device which promotes the clearance of pulmonary sputum. This possesses a metallic sphere which, oscillates during the expiration, generating oscillatory positive expiratory pressure. The aim of this study was to verify the performance of the national device of HFOO (Shaker, NCS, São Paulo) in relation to frequency of oscillation and expiratory pressure with variation of flow and inclination. METHODS: The device was imprisoned to a circuit that consisted of a pneumotacograph and a mechanical ventilator. This had the varied flow and during this variation the expiratory pressure and the frequency of oscillation of the device were measured in angulations which, varied of +40º to -40º. RESULTS: Significant correlation between flow and expiratory pressure in each level of inclination was found. A bigger frequency of oscillation and pressure was evidenced in the positive angulations with the biggest flows (50 and 60 L/min). CONCLUSIONS: The high frequency oral oscillation device can be used as an assist for the air way clearance therapy during mechanical ventilation.

BACKGROUND AND OBJECTIVES: The ventilator-associated pneumonia (VAP) is a severe infection that presents multiple causes which can vary depending on the type of intensive care unit, type of patients, emphasizing the needs for vigilance measures with local data. The aim of this study is to describe the incidence, risk factors and mortality of VAP in patients in a surgical ICU. METHODS: Prospective cohort conducted from January 2004 to January 2005. It was included all the patients in mechanical ventilation, followed daily to collect data about demographics, diagnostic, APACHE II and TISS 28 scores, duration of mechanical ventilation, length of stay, incidence of VAP and mortality. RESULTS: 462 patients were studied; age 57.2 ± 16.6 years, 55% men. The mean APACHE II score was 18.3 and the incidence of VAP was 18.8%. The TISS score at admission OR = 1.050 (IC 95%: 1.003-1.050) and the enteral nutrition OR = 5.609 (IC 3.351-9.388) were factors associated with VAP and the prophylactic use of antibiotics was a factor of protection OR = 0.399 (IC95%: 0.177-0.902). The patients with VAP had longer length of stay in ICU (10.3 ± 10.7 vs 4.9 ± 3.3 days), higher median of duration of mechanical ventilation (4 vs 1 days), higher mean of TISS 28 (24.4 ± 4.6 vs 22.8 ± 4.5), and higher crude mortality (46 vs 28.8%) when compared with the patients without VAP. CONCLUSIONS: VAP was a frequent infection in surgical patients in mechanical ventilation. Enteral nutrition and admission TISS were risk factors and the previous use of antibiotics was protection factor to develop VAP. In our sample the results demonstrate that VAP is associated with higher duration in mechanical ventilation, longer length of stay and higher mortality.

BACKGROUND AND OBJECTIVES: This study aims to describe the view of family members about the quality of care given in a general intensive care unit of a university hospital. METHODS: A questionnaire to evaluate the level of satisfaction with the care was elaborated. The study included family members of patients with a length of stay more than 48h who already had visited the patient one time or more during the period. The exclusion criterion was family of admitted patients with less than 48h of ICU stay, family members who had not visited the patient at all or family members who did not desire to answer the questionnaire for any personal reason. RESULTS: There were 100 relatives interviewed face to face. The most frequent complaint that had generated the greatest concern was the general status of the patient, present in 28% of the interviews. A total of 96% considered the quality of the medical team as excellent or good. However, 15% declared to be unsatisfied with the medical information given and the other 5%, although admitting satisfaction, complained about having to talk with different doctors each day. CONCLUSIONS: Imperfections in the communication appears as the main predictor of unsatisfactory quality of the service in the view of the family members. Although one cannot directly compare the degree of satisfaction between distinct studies due to different methodologies, we considered that in the presented sample the recognition of the most frequent factors of dissatisfaction can point out areas for improvement in the quality of care offered in the ICU.
