BACKGROUND AND AIMS: Data concerning postural hypotension (PH) induced by transition from supine to sitting position are scarce and measures for its prevention have not been investigated. Our objective was to assess the preventive role of lower limb compression bandaging on PH and associated manifestations in older inpatients when seated from lying position. METHODS: In a randomized crossover study, 61 patients aged >65 years were enrolled. Following bed rest lasting >36 h, each patient was seated and studied for 2 consecutive days, unbandaged or bandaged. PH was defined as a fall of >/=20 mm Hg and/or >/=10 mm Hg in systolic/diastolic blood pressure, respectively. Compression bandages were applied along both legs before seating; the pressure was approximately 30 mm Hg. Blood pressure, heart rate, O(2) saturation, dizziness and palpitations were recorded prior to and 1, 3, and 5 min following seating. RESULTS: Prevalence of PH was identical in the unbandaged versus bandaged state (55.7%). However, dizziness, palpitations, accelerated heart rate and decreased O(2) saturation over 5 min were more prevalent in the unbandaged versus bandaged state (p < 0.01, <0.001, <0.05, <0.001, respectively). In the unbandaged state, presence versus absence of PH was associated with significantly greater incidence of palpitations, tachycardia and decline of O(2) saturation over time (p < 0.04, <0.03, <0.03, respectively). In the bandaged state, O(2) saturation over 5 min tended to rise irrespective of PH, but mean values were higher in patients without PH (p < 0.02). CONCLUSIONS: Lower limb compression bandaging does not reduce the incidence of PH. However, associated manifestations are largely prevented.
