Research lines and projects

Description: Experimental studies in animals or clinical research to study the factors that influence the pain perception and the anesthetic or analgesic action of different forms of pharmacological or non-pharmacological treatment. The anesthetic technique may interfere in the outcome of the surgical patient and the pharmacokinetic/pharmacodynamic modeling study applied to the drugs used in the perioperative period allows a better understanding of the mechanism of action, the monitoring of the concentrations in different organic sites and the optimization of the therapeutic regimens used.

Description: The surgical patient has a risk of volemic and hemodynamic changes that may contribute to perioperative morbidity and mortality. There is great controversy regarding ideal techniques for monitoring blood volume, the best fluid for volume replacement, indications for transfusion of blood components and also the consequences of hypovolemia and excessive volemic replacement. Experimental and clinical models allows the critical analysis of the evidence on protective measures in situations of risk for renal failure and other organic lesions in response to hypovolemia, the use of crystalloid solutions, colloids and blood components, as well as the excessive use of these therapeutic options.

Description: Andragogy and teaching-learning processes related to the perioperative are dynamic and require directed actions so that the student deepens and amplifies the meanings elaborated through active participation that must lead to the acquisition of specific skills, abilities and attitudes. On the other hand, the teacher should carry out continuous reflective work and be available to monitor the evolution of the learner. Specific projects aim at the critical analysis of the tools used for teaching and student evaluation. Methodologies such as theoretical classes, practical learning, training workshops, simulation and the use of crisis and conflicts management tools should be analyzed together in the search for greater efficiency in teaching. Presentation, discussion and improvement of the methodological concepts on teaching, strategies and use of simulators, with evaluation of their results for undergraduate students, resident physicians, anesthesiologists, surgeons and intensivists can contribute to the optimization of teaching in the area.
