ABSTRACT
OBJECTIVE:
To assess the effects of patient-controlled abdominal compression on postural changes in systolic blood pressure (SBP) associated with orthostatic hypotension (OH). Secondary variables included subject assessments of their preferences and the ease-of-use.DESIGN:
Randomized crossover trial.SETTING:
Clinical research laboratory.PARTICIPANTS:
Adults with neurogenic OH (N=13).INTERVENTIONS:
Four maneuvers were performed moving from supine to standing without abdominal compression; moving from supine to standing with either a conventional or an adjustable abdominal binder in place; application of subject-determined maximal tolerable abdominal compression while standing; and while still erect, subsequent reduction of abdominal compression to a level the subject believed would be tolerable for a prolonged period. MAIN OUTCOMEMEASURES:
The primary outcome variable included postural changes in SBP. Secondary outcome variables included subject assessments of their preferences and ease of use.RESULTS:
Baseline median SBP in the supine position was not affected by mild (10mmHg) abdominal compression prior to rising (without abdominal compression 146mmHg; interquartile range, 124-164mmHg; with the conventional binder 145mmHg; interquartile range, 129-167mmHg; with the adjustable binder 153mmHg, interquartile range, 129-160mmHg; P=.85). Standing without a binder was associated with an -57mmHg (interquartile range, -40 to -76mmHg) SBP decrease. Levels of compression of 10mmHg applied prior to rising with the conventional and adjustable binders blunted these drops to -50mmHg (interquartile range, -33 to -70mmHg; P=.03) and -46mmHg (interquartile range, -34 to -75mmHg; P=.01), respectively. Increasing compression to subject-selected maximal tolerance while standing did not provide additional benefit and was associated with drops of -53mmHg (interquartile range, -26 to -71mmHg; P=.64) and -59mmHg (interquartile range, -49 to -76mmHg; P=.52) for the conventional and adjustable binders, respectively. Subsequent reduction of compression to more tolerable levels tended to worsen OH with both the conventional (-61mmHg; interquartile range, -33 to -80mmHg; P=.64) and adjustable (-67mmHg; interquartile range, -61 to -84mmHg; P=.79) binders. Subjects reported no differences in preferences between the binders in terms of preference or ease of use.CONCLUSIONS:
These results suggest that mild (10mmHg) abdominal compression prior to rising can ameliorate OH, but further compression once standing does not result in additional benefit.Palabras clave
