Despite recent advances in diagnosis and care of critically ill patients sepsis related mortality rate remains unacceptably high. Therefore, new methods of evaluation are necessary to provide an earlier and more accurate characterization of septic patients. Based on the (oncologic) TNM system, the PIRO concept was introduced as a new staging system for sepsis in order to assess risk and predict prognosis, with potential to assist in inclusion of patients in clinical studies and estimate the probability of response of patients to specific therapeutic interventions.

During the last few years, technological development and acquired experience advanced and the echocardiogram has become an important and useful tool in intensive care unit environment. Data obtained from semi quantitative Doppler echocardiography (transthoracic and transesophageal) evaluation has contributed to an appropriate patient monitoring and management. Echocardiography as a diagnostic, prognostic and monitoring method for fluid responsiveness assessment has become available nowadays since hand-carried ultrasound devices are portable and cheaper. Adequate training and development of appropriateness criteria for use of echocardiography in intensive care unit may lead to a standard use as a bedside tool.

OBJECTIVE: The understanding of adverse events may simplify the inquiry regarding the quality of nursing care, presuming a foregrounding role in evaluating health services. The aim of the study was to identify adverse events in nursing care in an intensive care unit. METHODS: Data were collected using an appropriate form known as problem-oriented record (POR) over a 10-month period; patients were monitored throughout their intensive care unit stay. RESULTS: Over the study period, 550 adverse events were recorded as follows: 26 concerned the "five rights" related to drug administration; 23 to non-administered medication; 181 to inappropriate medication records; 28 to failure in infusion pump assembly; 17 to not performed inhalation; 8 to incorrect handling of needles and syringes; 53 to not performed nursing procedures; 46 to incorrect handling of therapeutic and diagnostic devices; 37 to alarms/warnings of devices used incorrectly; and 131 to failure in data recording by nurses. CONCLUSION: The occurrence of adverse events in the care given to patients by the nursing team are significant indicators that disclose the quality of nursing care. Therefore, these events should be analyzed to support in-service training of the nursing staff.

Anemia is a prevalent issue in intensive care units. It appears in the first days, and may continue or worsen during hospital stay. Its etiology is generally multifactorial. Red blood cell transfusion is the most common intervention for treating anemia. Approximately 12 million blood units are used for transfusions in the United States, 25% to 30% in the intensive care units. Due to reduction of transfusion infections the increased safety has allowed an expansion of clinical indications. However, transfusion therapy is associated with other adverse effects such as nosocomial infections, immunological impairment, lung injury, hemolytic reactions and higher cancer incidence. Various papers have tried to show an association between correction of anemia and mortality-morbidity, but no consensus has been reached in literature. One of the current World Health Organization's proposals is to reduce potentially unnecessary transfusions, promoting a rational transfusion attitude. The primary objective of this narrative review is to approach controversies regarding the transfusion threshold according to recent studies, and as a secondary objective, it aims to discuss iatrogenic anemia aspects and the different behaviors among intensivists on the best practices for implementation of transfusion practices. It is not within our objectives to discuss transfusion complications, although they are mentioned. A search was conducted on electronic literature databases (PubMed - Clinical Queries), and UpToDate 16.2, and additional consultation to textbooks. It became clear that transfusion practices are widely variable among intensive care units. Evidence is scarce that routine transfusion in non-hemorrhagic patients should be used in those with > 7 g/dL hemoglobin. There is no consensus on the transfusion threshold in critically ill patients. Cardiovascular disease patients seem to present a higher risk of death than non-cardiovascular patients, for any level of hemoglobin. Transfusion guided by hemoglobin levels and individual oxy-hemodynamic physiologic parameters and clinical context is apparently, the current best accepted strategy, rather than arbitrary and isolated hemoglobin correction.

Constipation is a common complication identified among critically ill patients. Its incidence is highly variable due to lack of definition of such patients. Besides the already known consequences of constipation, in recent years it was observed that this complication may also be related to worse prognosis of critically ill patients. This review endeavors to describe the main available scientific evidence showing that constipation is a prognostic marker and a clinical representation of intestinal dysfunction, in addition to eventually interfering in the prognosis with treatment. Ogilvie syndrome, a major cause of morbidity and mortality in intensive care units was also reviewed. Considering the above cases it was concluded that more attention to this disorder is required in intensive care units as well as development of protocols for diagnosis and management of critically ill patients.

Case report of a patient with 37-week gestational age admitted to an obstetric intensive care unit with an altered level of consciousness, related primarily to the pregnancy-induced hypertension. The patient presented a worsening clinical course characterized by, anemia and severe thrombocytopenia, Investigation led to a diagnostic of thrombotic thrombocytopenic purpura after the hematological profile was assessed. The authors emphasize the importance of the disease recognition as a prognostic marker for obstetric patients, in view of the similarity with other common morbidities during pregnancy and the importance of timely diagnosis and early treatment as determinant factors for the outcome.

OBJECTIVES: The aim of this study was to evaluate the level of knowledge of health care professionals in an emergency situation related to tracheostomy tube displacement METHODS: a descriptive and exploratory study was carried out with the intensive care unit health professionals of a university hospital in Salvador, Brazil, from July to September 2007. For this purpose, a questionnaire was translated and adapted from a previous study. Questions were: 1- Have you dealt with this emergency? 2 - What is the first thing you do? 3- Do you know what the stay sutures are for? 4 - How are they used in an emergency setting? 5 -Do you know what to do with the introducer? RESULTS: the sample comprised 41 professionals (nine physicians, 20 nurses and 12 physiotherapists). A descriptive analysis showed that 63% of professionals had never experienced such complications. Analysis of a subgroup showed that 42% of physiotherapists, 56% of physicians and 69% of nurses would act inappropriately. Analyzing the level of knowledge about the importance of stay sutures, the study showed that 78% of the sample did not know what they were or how to use them, and 63.4% did not know how to use the introducer correctly. CONCLUSIONS: , regarding the use of a tracheostomy tube in a situation of emergency, the level of knowledge of the professionals evaluated was insufficient. The greatest shortcoming was detected in the level of knowledge about stay sutures.

Use of ultrasound introduced as part of intensive care therapy makes viable bedside invasive procedures and diagnosis. Due to portability, combined with team training, its use guarantees less complications related to insertion, as well as patients' safety. It also reduces severe conditions related to the catheter, such as pneumothorax among others. Probably, in a near future, as purchase of ultrasound equipment becomes easier and team training more adequate, this tool will become essential in daily clinical practice.
