OBJECTIVES: To assess the physician’s knowledge on intubation techniques and to identify the common practices. METHODS: This was a prospective study, involving three different intensive care units within a University hospital: Anesthesiology (ANEST), Pulmonology (PULMO) and Emergency Department (ED). All physicians working in these units and consenting to participate in the study completed a questionnaire with their demographic data and questions on orotracheal intubation. RESULTS: 85 completed questionnaires were retrieved (90.42% of the physicians). ANEST had the higher mean age (p=0.001), being 43.5% of them intensivists. The use of hypnotic and opioid association was reported by 97.6%, and pre-oxygenation by 91.8%, but only 44.6% reported sub-occipital pad use, with no difference between the ICUs. On ANEST an increased neuromuscular blockade use was reported (p<0.000) as well as increased caution with full stomach (p=0.002). The rapid sequence knowledge was restricted (mean 2.20 ± 0.89), p=0.06 between the different units. The Sellick maneuver was known by 97.6%, but 72% used it inappropriately. CONCLUSIONS: Physicians knowledge on orotracheal intubation in the intensive care unit is unsatisfactory, even among qualified professionals. It is necessary to check if the responses to the questionnaire and actual clinical practices agree.

INTRODUCTION: Central venous oxygen saturation (SvcO2) has been proposed as an alternative for mixed venous oxygen saturation (SvO2), with a variable level of acceptance according to available data. This study aimed to evaluate possible differences between SvO2 and SvcO2 or atrial venous saturation (SvaO2), with emphasis on the role of cardiac output and their impact on clinical management of the septic patient. METHODS: This is an observational, prospective study of patients with septic shock monitored by pulmonary artery catheter. Blood was obtained simultaneously for SvcO2, SvO2 and SvaO2 determination. Linear correlation (significant if p<0.05) and agreement analysis (Bland-Altman) were performed with samples and subgroups according to cardiac output. Moreover, agreement about clinical management based on these samples was evaluated. RESULTS: Sixty one measurements from 23 patients were obtained, median age of 65.0 (49.0-75.0) years and mean APACHE II of 27.7±6.3. Mean values of SvO2, SvcO2 and SvaO2 were 72.20±8.26%, 74.61±7.60% and 74.64±8.47%. Linear correlation test showed a weak correlation between SvO2 and SvcO2 (r=0.61, p<0.0001) and also between SvO2 and SvaO2 (r=0.70, p<0.0001). Agreements between SvcO2/SvO2 and SvaO2/SvO2 were -2.40±1.96 (-16.20 and 11.40) and -2.40±1.96 (-15.10 and 10.20), respectively, with no difference in the cardiac output subgroups. No agreement was found in clinical management for 27.8% of the cases, both for SvcO2/SvO2 and for SvaO2/SvO2. CONCLUSION: This study showed that the correlation and agreement between SvO2 and SvcO2 is weak and may lead to different clinical management.
