Does desmopressin improve hemostasis and reduce blood loss from aortic surgery?
Thrombocytopenia and mild platelet dysfunction are common after aortic operation, but DDAVP does not improve hemostasis or lessen transfusion requirements. This study does not rule out a beneficial effect of DDAVP in patients who are undergoing more complex aortic operations or who have major hemostatic aberrations.
PBL does not require an increase in number of faculty. The time spent by faculty on educational activities was similar in the two curriculum models. Although the cost of two strategies was similar, but the educational roles and the faculty engagement in education in a PBL curriculum is broader than in the traditional curriculum.
