Stress management training for hypertensives: cognitive and physiological effects.

The contribution of training procedures designed to alter individuals' psychological responses to stressful life stimuli to the reduction of blood-pressure levels of hypertensives was evaluated. The treatment consisted of a set of coping skill-building experiences. Forty-one black males, mildly to moderately hypertensive and under medical supervision in an outpatient cardiovascular unit of a veterans' hospital, participated. Subjects were randomly assigned to one of three groups: Cognitive Self-Management Training (CSM), Attention Placebo Control, and Current Clinic Conditions Control. The dependent measures were the State Anxiety Scale, Trait Anxiety Scale, Coping Strategic Inventory, systolic blood pressure, and diastolic blood pressure. Subjects in the CSM group reported significant increases in the use of cognitive coping strategies in their lives and demonstrated significant decreases in measured levels of state anxiety and systolic blood pressure. Promising reductions of diastolic blood pressure ratings were obtained as well.

Catheter infection. A comparison of two catheter maintenance techniques.

Incidence of catheter-related infections was studied using two techniques: changing catheters over a guide-wire or placing a new catheter at a new site every 3 days. Patients were randomized into two groups: Group 1 (new site) and Group 2 (guide-wire). Of the 105 catheterization sites (20 arterial and 85 central lines) in patients of Group 1, none were considered infected (i.e., having 15 or more colonies at the time of semi-quantitative microbiology analysis and clinical signs of infection at the catheter site). Of the 274 catheterization sites (56 arterial and 218 central) of patients of Group 2, eight (2.9%) were infected (chi 2 = 1.89, p greater than 0.05). Colonization (15 or more cultures without clinical signs of infection) occurred in three of 105 (2.9%) and in four of 274 (1.5%) of the catheterization sites of Groups 1 and 2, respectively (chi 2 = 0.23, p greater than 0.05). Study results indicate no significant difference in infection or colonization rates between the two methods of catheter replacement.
