11. Patient Profiles:
What about hemodynamic effects of preoperatively
administered atenolol? Well, there weren't any differences in
systolic or diastolic blood pressure. Anesthesiologists worry
that giving a beta blocker prior to induction is going to have
some catastrophic effect. There is NO evidence of such a problem.
The heart rates are lower in the atenolol treated patients that
is the only identifiable hemodynamic difference.
