question:
Question: Is preoperative prolonged steroid use associated with intraoperative blood transfusion in noncardiac surgical patients?
Answer: The effect of prolonged steroid use on bleeding, if any, thus seems likely to be small and is probably of limited clinical consequence. In contrast, corticosteroid use augments the risk of both systemic and wound infections.
answer:
no

answer:
no


question:
Question: Is reverse rate dependency an intrinsic property of canine cardiac preparations?
Answer: RRD of APD modulation is shared, although with differences in magnitude, by interventions of very different nature. RRD can be interpreted as a consequence of the relationship between I(m) and APD and, as such, is expected in all species having positive APD-CL relationship. This implies that the development of agents prolonging APD with direct rate dependency, or even completely devoid of RRD, may be difficult to achieve.
answer:

yes
