Context:The performance of each ICU needs to be assessed within the overall context of medical care, as well as by the institution which the ICU forms part of. Evaluation mechanisms in the field of intensive care have been developed that are recognized worldwide within the scientific literature. Objective: To study outcomes from groups of critical patients and to compare their actual and estimated mortality rates. Design: Prospective study of patients' outcomes. Setting: A tertiary care unit for a period of 13 months (anesthesiology intensive care unit at the Escola Paulista de Medicina). Participants: 520 patients selected according to sex, age and nature of hospitalization. Diagnostic Test: The modified APACHE II prognostic index was applied in order to assess clinical severity and anticipation of mortality in three groups who had nonsurgical treatment, emergency surgery and elective surgery. Main measurements: The APACHE II index. Results: The application of this index allowed patients to be stratified and expected death risks for both subgroups and the entire sample population to be calculated. The observed mortality rate was greater than the expected rate (28.5% versus 23.6%, respectively), with a statistically significant difference. The standardized mortality rate was 1.20. Patients who obtained scores above 25 presented a significant outcome towards death. The most severe and worst evolving cases were, in decreasing order: non-surgical, emergency surgical and scheduled surgical patients; the actual general mortality rate was higher than the expected one. Conclusions: The use of the APACHE II index made it possible to stratify critical patient groups according to the severity of their condition.

A large proportion of patients have a limited knowledge about the education and role of anesthesiologists. Pre-anesthetic evaluation did not increase the proportion of answers that anesthesiologists have medical education.

This case series support the discussion on conducting surface peripheral nerve blocks and easy local knowledge as the axillary, interscalene, femoral, saphenous or popliteal in anticoagulated patients, on dual antiaggregation therapy and/or with other coagulation disorders, provided that guided by ultrasound and performed by an anesthesiologist with extensive experience in guided nerve blocks. However, larger series should be performed to prove the safety of the technique for these patients.

This study showed a broad individual variety of the RSI technique, a fact already reported by different authors. The difficulty in establishing a RSI protocol can be attributed to constant evidence that science provides us, where updating over the years becomes good medical practice.

Background and objectives: Modern international studies portray the lack of knowledge of patients regarding the education and role of anesthesiologists. There are no current data on this subject in the national scenario. The objective of this study was to assess the level of knowledge of patients about the education and areas of performance of these specialists.

Background and objectives:The induction of the general anesthesia in patients on "a full stomach" can result in regurgitation of the gastric content and pulmonary aspiration. The function of the rapid sequence induction (RSI) is to minimize the time interval between the loss of the airway protection reflexes and tracheal intubation tube balloon. The objective of this study was to evaluate the rapid sequence induction among the anesthesiologists of the São Paulo Hospital. Methods:The participants answered the questionnaire voluntarily and anonymously, after signed consent. The questionnaire consisted of 60 questions about the fundamental points of the RSI. The questions were divided in pre-oxygenation, circuits, drugs used in the induction (opioids, hypnotics, neuromuscular blockers), cricoid pressure techniques, intubation and difficult intubation.Results: Seventy-five questionnaires were applied and 22 were discarded due to incomplete answering. All anesthesiologists always declare doing pre-oxygenation and administering opioid, hypnotic, and neuromuscular blocker. Most use fentanyl (83%), propofol (74.5%) and succinylcoline (68.6%). All anesthesiologists apply cricoid pressure. Most did not know the correct pressure to be applied on the cricoid cartilage. Intubation failures have already occurred with 71.7% of anesthesiologists and with 40%, the regurgitation. When faced with an unexpected difficult intubation, anesthesiologists ask for the laryngeal mask (35.5%). Conclusions:This study showed a broad individual variety of the RSI technique, a fact already reported by different authors. The difficulty in establishing a RSI protocol can be attributed to constant evidence that science provides us, where updating over the years becomes good medical practice .
