Randomized comparison of hemostasis techniques after invasive cardiovascular procedures.

Background: The arterial access required during most invasive vascular procedures provides a common source of complications and morbidity. This problem has been made worse by recent trends in earlier ambulation and more aggressive antihemostatic drug regimens. Despite these trends, no randomized trials have been reported comparing the 3 most commonly used techniques in achieving hemostasis at the arterial puncture site.

Behavioral measurement of temperament in male nursery-raised infant macaques and baboons.

We define temperament as an individual's set of characteristic behavioral responses to novel or challenging stimuli. This study adapted a temperament scale used with rhesus macaques by Schneider and colleagues [American Journal of Primatology 25:137-155, 1991] for use with male pigtailed macaque (Macaca nemestrina, n = 7), longtailed macaque (M. fascicularis, n = 3), and baboon infants (Papio cynocephalus anubis, n = 4).

Maintenance of hemostasis after invasive cardiac procedures: implications for outpatient catheterization.

Objectives: This study investigated the efficacy of four different methods of arterial puncture site management during recovery from invasive cardiac procedures. The primary goals were less patient discomfort and improved clinical outcome.

Background: The increasing use of outpatient catheterization, large interventional devices and potent periprocedural anticoagulation regimens has made the reduction of groin complications a high priority.
