Effect of different anesthetic agents on left ventricular systolic function assessed by echocardiography in hamsters BJMBR
Tanaka,D.M.; Romano,M.M.D.; Carvalho,E.E.V.; Oliveira,L.F.L.; Souza,H.C.D.; Maciel,B.C.; Salgado,H.C.; Fazan-Júnior,R.; Simões,M.V..
Determination of left ventricular ejection fraction (LVEF) using in vivo imaging is the cardiac functional parameter most frequently employed in preclinical research. However, there is considerable conflict regarding the effects of anesthetic agents on LVEF. This study aimed at assessing the effects of various anesthetic agents on LVEF in hamsters using transthoracic echocardiography. Twelve female hamsters were submitted to echocardiography imaging separated by 1-week intervals under the following conditions: 1) conscious animals, 2) animals anesthetized with isoflurane (inhaled ISO, 3 L/min), 3) animals anesthetized with thiopental (TP, 50 mg/kg, intraperitoneal), and 4) animals anesthetized with 100 mg/kg ketamine plus 10 mg/kg xylazine injected...

Can course format influence the performance of students in an advanced cardiac life support (ACLS) program? BJMBR
Garrido,F.D.; Romano,M.M.D.; Schmidt,A.; Pazin-Filho,A..
Advanced cardiac life support (ACLS) is a problem-based course that employs simulation techniques to teach the standard management techniques of cardiovascular emergencies. Its structure is periodically revised according to new versions of the American Heart Association guidelines. Since it was introduced in Brazil in 1996, the ACLS has been through two conceptual and structural changes. Detailed documented reports on the effect of these changes on student performance are limited. The objective of the present study was to evaluate the effect of conceptual and structural changes of the course on student ACLS performance at a Brazilian training center. This was a retrospective study of 3266 students divided into two groups according to the teaching model:...

Minor segmental wall motion abnormalities detected in patients with Chagas' disease have adverse prognostic implications BJMBR
Pazin-Filho,A.; Romano,M.M.D.; Almeida-Filho,O.C.; Furuta,M.S.; Viviani,L.F.; Schmidt,A.; Marin-Neto,J.A.; Maciel,B.C..
Recent data from our laboratory have shown that patients with the indeterminate form of Chagas' disease can have impairment of left ventricular contractility, as evaluated by the slope of the left ventricle end-systolic pressure-dimension relationship. We also showed that Chagas' disease patients with minimal baseline wall motion abnormalities detected by two-dimensional echocardiography have more intense contractility impairment when compared to patients with the indeterminate form of the disease without this abnormality. The prognostic implications of these findings have not been established. We evaluated 59 patients (37-76 years, mean = 55 years) with different clinical forms of Chagas' disease, who had normal left ventricular global systolic function...
