Views1See moreBACKGROUND AND OBJECTIVES: There is a growing tendency of looking for “dying with dignity”, rather than to prolong death and suffering of terminal patients on intensive care units (ICU). This study aims to evaluate medical practices that suggest therapeutic limitation (TL) in patients who died in an adult ICU. METHODS: A retrospective exploratory study was carried out to evaluate medical records of patients who died in a general adult ICU of a private hospital in Salvador-BA, between January and August of 2003, after at least 24 hours from the admission. The patients were classified, in relation to their deaths, in: “not responding to cardiopulmonary resuscitation”, “brain death”, “decision not to resuscitate” (DNR) and “withhold or withdrawal life-support measures”. RESULTS: Sixty seven patients were included, corresponding to 90.4% of the deaths occurred in this ICU during the referred period. The most of them (56.7%) were women and the patients’ mean age was 66.58 ± 17.86 years. Suggestive measures of TL were found in 59.7% of the patients, being “withhold of life-support measures” the most important (35.8%), followed by DNR (17.9%) and “withdrawal of life-support measures” (6%). The procedures most commonly omitted were use of vasoactive drugs and dialysis, while antibiotics were the most discontinued. The use of TL measures was more frequent in clinical patients. CONCLUSIONS: The results of the present study suggest high frequencies of medical conducts suggestive of TL in a general ICU in Northeast of Brazil. Therapeutic methods that could cause discomfort or suffering to the patients, as nutrition, sedation and analgesia, were rarely omitted or discontinued.

This study aims to evaluate the knowledge of a sample of Medical students on the Brazilian BD diagnosis protocol. METHODS: Descriptive cross-sectional survey that evaluated students from two medical schools in Salvador-BA. We used a questionnaire composed by questions about technical and ethical knowledge contained in the Federal Council of Medicine’s Resolution nº 1480/97 that establishes the criteria for BD diagnosis. RESULTS: We evaluated 115 Medical students. In 14 questions about the knowledge of BD criteria, the mean of right answers were 6.7 ± 1.8, which were higher among the students that had attended some presentation on BD. Most of the students (87.4%) knew how to identify the candidates to the BD diagnosis protocol. However, only 5.2% and 16.1% of the students answered right, respectively, the clinical and complementary tests that should be accomplished during the diagnosis protocol. Facing a no-donor patient with confirmed diagnosis of BD, 66.4% referred that artificial life support should be suspended. Only 15% of the interviewed students had already evaluated a patient with BD, being this percentage higher among those who had already frequented ICU (38.2% versus 5.1%; p < 0.001). CONCLUSIONS: The results of this study showed a limited knowledge of the evaluated students on BD diagnosis criteria, mainly in relation to the practical approach of this condition.

Views0See moreBACKGROUND AND OBJECTIVES: Currently, the reformulation of intensive care goals, often shifting from the search for a cure to offering comfort, has become more and more necessary. The intensivist is frequently confronted with the decision to suspend or not offer a specific therapy, despite its availability. The objective of this study was to estimate the developing risk of probability of death for individual ICU patients with respiratory failure, identify which life-sustaining therapies were administered, time of internment and outcome. Compare the death outcome in relation to UNICAMP II and APACHE II models, as well as verify if the life-sustaining therapies may be limited or suspended. METHODS: It is the observational, prospective cohort study of 150 patients with respiratory failure confined to the intensive care unit. Statistical analysis was carried out using Generalized Linear Models. RESULTS: Age, sex, race or morbidity did not reveal statistical significance in predicting outcome. This prediction was confirmed more accurately by means of changes in the individual prognostic index of death probability during the first seven days of ICU internment. A 10% worsening prognosis in patients who presented initial death risk of 70% to 80%, utilizing the UNICAMP II Model, showed a specificity of 97.4% – 98.6%. CONCLUSIONS: Prognostic changes in patients during the first seven days of ICU internment are of great aid, from an objective point of view, for ethical decision-making in relation to not-offering new life-sustaining therapies.

Views0See moreBACKGROUND AND OBJECTIVES: The chest physiotherapy (CP) in patients submitted to invasive support ventilation acts directly in the breathing system, and it could alter the lung mechanics through the dynamic lung compliance (DynC) and resistance of the breathing system (Rbs). However the alterations after the accomplishment of CP are still controversy. The objective of this study was to evaluate the alterations of the lung mechanics in patients in invasive mechanical ventilation (IMV). METHODS: It was a prospective, randomized, and controlled and crossover study, with patient with more than 48 hours in IMV. The protocol of chest physiotherapy and isolated tracheal aspiration they were randomized for the application order with a window of 24 hours among them. Data of lung mechanics and its varied cardiorespiratory were collected moments before the protocol, immediately after the application of the protocol, 30 minutes and 120 minutes after the application of the protocols. RESULTS: Twelve patients completed the study. Pneumonia was the mean cause respiratory failure (RF). There was not statistical difference among the groups in relation to Cdyn, volume tidal (Vt) and volume minute (Ve). Rbs decreased in a significant way immediately after (of 10.4 ± 3 cmH2O/L/seg for 8.9 ± 2 cmH2O/L/seg; p < 0.02), 30 minutes after (of 10.4 ± 3 cmH2O/L/seg for 9 ± 2 cmH2O/L/seg; p < 0.01) and 120 minutes after (of 10.4 ± 3 cmH2O/L/seg for 9 ± 2 cmH2O/L/seg; p < 0.03) application the protocol of chest physiotherapy. When compared with the protocol of isolated tracheal aspiration it was significantly smaller in the 30 (9 ± 2 cmH2O/L/seg versus10.2 ± 2 cmH2O/L/seg; p < 0.04) and 120 minutes (9 ± 2 cmH2O/L/seg versus 10.4 ± 3 cmH2O/L/seg; p < 0.04). CONCLUSIONS: The protocol of chest physiotherapy was effective in the decrease of Rsr when compared with the aspiration protocol. That decrease was maintained for two hours after its application, what did not happen when only the just accomplished the tracheal aspiration was performed isolated.

Views0See moreBACKGROUND AND OBJECTIVES: Actually, It’s doubtful if early tracheostomy (ET) can influence mechanical ventilation (MV) weaning time or the hospital length of stay in patients with traumatic brain injury (TBI). The main objective of this trial was to verify the influence of ET on weaning time of patients with severe TBI. METHODS: Prospective, observational study, including 33 patients with severe TBI (GCS < 10 at hospital admission), evaluated according to tracheostomy performance time (early: t < 6 days; intermediate: t = 7 to 11 days; and late: t > 12 days) and the weaning from MV. RESULTS: Total ventilation mechanical time has been reduced in the early tracheostomy group (n = 10; p < 0.0001). A lower GCS punctuation (mean 5.3 ± 2.5) in ET group has been negatively correlated with hospital length of stay (LOS) (p = 0.02). CONCLUSIONS: Early tracheostomy can decrease mechanical ventilation time, but does not influence hospital LOS in patients with severe traumatic brain injury.

Views0BACKGROUND AND OBJECTIVES: The adverse effects of intra-abdominal hypertension are known for many years. Only recently proper attention has been given to routine intra-abdominal pressure (IAP) monitoring. There is evidence that a quarter of intensive care units (ICU) do not measure IAP, due to a lack of knowledge of its importance or difficulty in results interpretation. The aim of this study is investigate the knowledge of ICU physicians about abdominal compartimental syndrome and its management. METHODS: A questionnaire with 12 questions about this issue was mailed to ICU physicians. RESULTS: The current knowledge of the international definitions of ACS does not seem to be linked to the number of years of medical practice, but was associated with the time spent working on intensive care. Although most physicians are aware of the existence of ACS, less than half know the present international definitions. The IAP monitoring is performed in patients at risk for ACS, by means of the intravesical filling with 25 to 100 mL of liquids, in intervals varying from of 4 to 8 hours. There was no consensus on the value of IAP values (with or without organ dysfunctions) for the clinical or surgical treatments of ACS in this survey. CONCLUSIONS: The knowledge of ACS is satisfactory when we consider only physicians that devote most of their time to ICU work. However, it is necessary to improve education and knowledge of most intensive care physicians regarding the presence and severity of intra-abdominal hypertension in Rio de Janeiro.

Views0See moreBACKGROUND AND OBJECTIVES: Organ transplantation has long been considered the treatment of choice for many end-stage organ diseases. As soon as transplantation turned to be a viable therapy, organ shortage became the major limitation for the procedures. Nowadays, there is an increasing imbalance between organ supply and demand. Apparently, the most promising way to increase organ supply is optimizing the care for the brain death organ donor. The objective of this manuscript was to review the pathophysiological aspects and therapeutic strategies for the optimized care of the potential organ donor. CONTENTS: Brain death causes a massive catecholamine release, inducing a variety of deleterious effects that can threat organ perfusion. Studies have documented a sudden decrease in cortisol, insulin, thyroid and pituitary hormones. In this scenario of hemodynamic and metabolic instability, a special attention to the multiple organ donor support is required. CONCLUSIONS: An extensive knowledge of the complex brain death pathophysiology is extremely important for the implementation of rational aggressive management protocols of the potential organ donor, aiming to increase the number of harvested organs and the number of organs harvested per donor.

Views0BACKGROUND AND OBJECTIVES: Sepsis is the expression of a complex network of mediators. Multiple organ dysfunction and septic shock indeed remain a major cause of death among ICU patients worldwide. Prompt recognition of both the diagnosis and the complicated evolution are essential, hence the importance of using biological markers. The main pro-inflammatory and anti-inflammatory cytokines as well as hundreds of others cellular markers, circulating bioactive molecules or coagulation products are potential biological markers that could help to characterize the presence of infection and sepsis. We aimed to review the main biological markers that could be used nowadays or possibly in the future, either in clinical or research fields. CONTENTS: A selective review of biologic markers of sepsis focusing on markers of the coagulation cascade, C-reactive protein and procalcitonin. CONCLUSIONS: Most of the available biological markers is still not a practical method to be used at the bed-side and is currently restricted to research works. Nowadays the determination of CRP or PCT serum levels can be of great help in the critically ill patient care along with the conventional parameters.

Views0See moreBACKGROUND AND OBJECTIVES: Myocardial contusion is often associated with blunt chest trauma. Its diagnosis is challenging to the professionals who work in emergency department due to nonspecific symptoms and the lack of auxiliary exams with enough accuracy to diagnose. Among the available diagnostic tools, the biomarkers of myocardial injury troponin I and troponin T have stood out. Troponins are proteins of the citocellular apparatus, released into the bloodstream only after the disruption of myocytes cellular membrane. Therefore they are highly specific to detect myocardial injuries. CONTENTS: We performed a clinical review using the electronic databases MedLine and LILACS from January 1980 to November 2006 about the importance of a serial measurement of troponin I and T as a diagnostic tool as well as predictor of unfavorable clinical outcome in patients with myocardial contusion after a blunt chest trauma. CONCLUSIONS: Although troponins I and T are more specific than usual biomarkers CKMB and CK, these two first biomarkers show a low sensitivity and positive predictive value to diagnosis myocardial contusion. Patients with ECG abnormalities, troponins elevations or both should remain in an intensive care unit (ICU) for at least 24 hours, period in which they cam develop most of the complications related to myocardial contusion.

Views0See moreBACKGROUND AND OBJECTIVES: Mechanically ventilated patients usually present larger amounts of pulmonary secretions because of impairment in mucociliary function and mucus transport. The manual resuscitator is considered a resource for pulmonary hyperinflation with the aim of preventing mucus retention and pulmonary complications, improving oxygenation and reexpanding collapsed areas. Alternatively, the hyperinflation by mechanical ventilator is a reliable and practical device to promote lung expansion and desobstruction. The objective of this study was to review the literature concerning manual and ventilator hyperinflation treatments for patients in the intensive care units (ICU) setting. CONTENTS: Literature searches were performed using the databases MedLine, CINAHL, SciElo and LILACS with appropriate keywords, including: intensive care units, manual hyperinflation, mechanical ventilator, physiotherapy, physical therapy and ventilator hyperinflation. CONCLUSIONS: Although there are few studies demonstrating the efficacy of ventilator hyperinflation as a physical therapy device, it can be a safety option to promote therapeutic hyperinflation in ICU, compared to manual hyperinflation.

Views1See moreBACKGROUND AND OBJECTIVES: Malaria is still considered a major global health problem. The severity form of the disease is caused, mainly by P. falciparum and may occur together with cerebral, kidney, pulmonary, hematologic, circulatory and hepatic complications. This report is about a patient with a case of severe imported malaria. CASE REPORT: A 30-years-old man, mulatto, Philippine, sailor, coming from a ship arriving from Nigeria, with a history of abdominal pain on the right hypochondrium, jaundice, fever, decreased in the consciousness. Lab tests made upon his admission showed hyperbilirubinemia at a level of 50 mg/dL, severe metabolic acidosis, thrombocytopenia, creatinine levels of 5.6 mg/dL and leukocytosis with deviation through metamyelocytes. The APACHE II score was 37, with death estimated risk of 88%. During his stay at the hospital, P. Falciparum Malaria was diagnosed through the thick drop test. And, even with the adequate anti-malaria therapy, the patient’s condition evolved to an acute renal failure requiring hemodialis; acute respiratory distress syndrome (ARDS); septic shock, and hematological disorders, forming a multiple organ dysfunction syndrome (MODS). After being discharged from the hospital, the patient did not present any cerebral, pulmonary or kidney sequel. CONCLUSIONS: From the criteria described in medical literature to define critical malaria, the patient fulfilled the following: acute renal failure, ARDS, metabolic acidosis, altered level of consciousness, macroscopic hemoglobinuria, hyperparasitism and hyperbilirubinemia, related to a lethality rate of over 10%, depending on early treatment and available resources. Severe malaria requires fast diagnosis allied to a quick access to an intensive care treatment, since any delay increases the morbid-mortality of the disease.

Views0See moreBACKGROUND AND OBJECTIVES: Amniotic fluid embolism is a rare complication of pregnancy whose physiopathology is not completely known and still not frequently remembered by intensive care physicians and obstetricians. The main aim of this case report was to emphasize the need of better knowledge of this disease by physicians. CASE REPORT: A 15 years old, primigravida, 35th week of gestation was admitted in our intensive care unit (ICU) with a sudden respiratory distress. Soon after admission she was intubated and put on mechanical ventilation. After stabilization she was transferred to the operating room and a cesarean section was undertaken. During the operation, instead of fluid reposition with crystalloids in large amounts, her hemodynamic status deteriorated and it was necessary to use vasoactive drugs. After three days on mechanical ventilation she was successfully weaned and discharged from the intensive care unit (ICU) after 6 days. She and her baby were discharged from hospital on13th day of hospitalization. CONCLUSIONS: Amniotic fluid embolism is a rare and catastrophic complication of pregnancy, at least in its classic presentation. It is characterized by acute respiratory distress, hemodynamic compromise and coagulopathy that occur during or within 30 min after labor. Diagnosis is by exclusion of other conditions of pregnancy or diseases that can be aggravated during pregnancy such as eclampsia, sepsis, pos-partum cardiomyopathy, anaphylaxis, pulmonary thromboembolism, transfusion reactions, anesthetic complications and mitral stenosis. There is growing evidence that we have a spectrum of manifestation which can be more common that in the classic ones. The treatment is supportive of vital functions, such as mechanical ventilation, fluid reposition, vasoactive drugs and fresh frozen plasma as necessary. The intensive care physicians and obstetricians should be aware of this disease in order to make early diagnosis and prompt treatment.

Views0See moreBACKGROUND AND OBJECTIVES: Sepsis during pregnancy is a rare complication. This potentially fatal disease often occurs due to maternal infectious and can lead to fetal loss. Therefore, any attempted treatment must be aimed at the mother’s well being. As a matter of fact, there are few recent medical publications about sepsis in pregnancy. In spite of this, the treatment based on Surviving Sepsis Campaign seems suitable and practical. The aim of this article is making a case report highlighting a very well succeeded treatment of a pregnant woman with urinary sepsis. CASE REPORT: A 22 year old in her 27th week of pregnancy is hospitalized with pyelonefhritis. One day later, she begins presenting signs of sepsis and unresponsive hypoxemia, resulting in intubation. Afterwards, she evolved with persistent low blood pressure that was unresponsive to volume expansion and had to be put on vasopressor medication. She received intensive care support based on Surviving Sepsis Campaign. The patient evolved with an important improvement of her ventilatory stats and was extubated. After completing antibiotic treatment, she was discharged and delivered a healthy baby after 42 weeks pregnancy. CONCLUSIONS: Sepsis in pregnancy is a rare and potentially fatal complication. The main treatment is based on Surviving Sepsis Campaign. The patient had an outstanding improvement and overcame her condition after intensive care support.
