ABSTRACT: Although the choice to study medicine implies some knowledge of the current working situation of practitioners, medical students' expectations regarding their future professional practice have been rarely investigated in Argentina. The aim of this work was to collect data about the expectations of senior medical students regarding their future professional practice. One hundred and twenty-five senior medical students were surveyed between September and December 2008. By using an anonymous survey, information regarding the expectations about their future professional practice was collected. The survey was answered by 82.4% (103/125) of the students and 98.0% (101/103) expressed their desire to enter a residence programme. Regarding specialty, pediatrics and psychiatry were the most chosen by women (27% vs. 8%, p=0.029 and 27% vs. 3%, p=0.004), and orthopedic surgery was the predominant choice in men (18% vs. 2%, p=0.019). Median of expected income at 5 years post graduation was $ 4.000 (minimum: $1,500, maximum: $10.000), at 10 years $7.000 (minimum: $3.000, maximum: $ 20.000) and at 20 years $10.000 (minimum: $3.000, maximum: $30,000), according to money value adjusted to December 2008 ($3.0 = US$ 1.0). In conclusion, chosen specialties seem to be dependent on the increasing number of female students, the expected income would exceed the current remuneration of physicians. Noteworthy finding out the students' willingness to be involved in teaching and the less interest in research.Medicina 01/2009; 69(6):607-11. · 0.47 Impact Factor
Article: [Operating room extubation (ultra fast-track anesthesia) in patients undergoing on-pump and off-pump cardiac surgery].[show abstract] [hide abstract]
ABSTRACT: The potential benefit of immediate operating room extubation after cardiac surgery remains controversial. Since safety and effectiveness of ultra fast-track anesthesia is mandatory, we developed this work to identify preoperative and operative variables associated to failed extubation after on-pump and off-pump cardiac surgery. Three hundred ninety eight consecutive patients undergoing coronary, valve or combined surgery were included in a prospective observational study of ultra fast-track anesthesia. Primary outcome was failed tracheal extubation, defined as the impossibility to extubate in the operating room immediately after surgery. Secondary outcomes evaluated need for postoperative tracheal reintubation, morbidity and mortality. Univariate analysis and multivariate logistic regression were done over 24 preoperative and operative variables to determine factors associated with failed tracheal extubation after on-pump and off-pump surgery. Sixty eight per cent of patients undergoing on-pump surgery, and 87.1% of those undergoing off-pump coronary revascularization were successfully extubated in the operating room. Univariate analysis in the on-pump group found that heart failure, left ventricular dysfunction, urgency, cross-clamping time, pacemaker requirement and difficult cardiopulmonary by-pass weaning were related to failed tracheal extubation; while heart failure and difficult cardiopulmonary bypass weaning were variables associated in the multivariate analysis. In the off-pump coronary surgery group, univariate analysis showed that pulmonary disease, urgency, pacemaker requirement and hemodynamic compromise during 'heart dislocation' were associated to failed extubation in the operating room. In this case, logistic analysis found obesity, pacemaker usage and hemodynamic compromise as factors related to failed extubation. Preoperative and operative factors associated to failed extubation could be used as guidelines to improve safety in ultra fast-track cardiac anesthesia. Especially, patients undergoing on-pump surgery with antecedents of heart failure or difficult cardiopulmonary by-pass weaning should not be extubated in the operating room. In the same way, immediate extubation should be avoided in obese patients with hemodynamic compromise during off-pump coronary surgery.Archivos de cardiología de México 76(4):383-9.

ABSTRACT: Although usage of variable life-adjusted display (VLAD) in medicine was proposed a decade ago, there is only little experience in mortality and morbidity monitoring with this method. The work objective was to study the utility of VLAD for continuous monitoring of cardiac surgery quality indicators. A continuous monitoring of morbidity and mortality with VLADs, was performed in a prospective series of 502 cardiac surgeries. VLAD plots for mortality, reopening for bleeding, deep sternal wound infection, stroke, myocardial infarction and need for postoperative dialysis were done. Mortality was risk-adjusted with Euro-SCORE, while postoperative complications were adjusted with a morbidity risk score. Additionally, internal thoracic artery graft usage in coronary surgery was plotted. VLADs based on risk-adjusted morbidities and mortality could identify several clusters of adverse results, occurring at different periods of time, as well as its temporal relations. In the same way, it could be determined along the series, the net lives saved, the complications avoided and the internal thoracic artery graft usage. Continuous monitoring with VLAD plots would provide on-line control of cardiac surgery outcomes. This method would be, not only useful for mortality supervision, but to check risk-adjusted morbidity and to control other quality indicators, such as internal thoracic artery usage.Archivos de cardiología de México 77(4):275-83.
