Factors associated with prevention of postural hypotension by leg compression bandaging.

Aim. We evaluated the eventual effects of leg compression on seating-induced postural hypotension (PH) in the context of various relevant clinical variables. Methods. Included were 73 hospitalized patients with various acute conditions, aged >= 60 years, bedridden for >= 8 h, with diagnosed PH [>= 20 mmHg systolic and/or >= 10 mmHg diastolic blood pressure (BP) falls] at the first seating. BP, heart rhythm, dizziness and palpitations were recorded before and during 5 min of sitting. The next day, the patients were reevaluated, this time using compression bandages applied along both legs before seating. Results. Compared with the non-bandaged state, PH was registered in only 53% of bandaged patients (p < 0.001). Moreover, the appearance of PH symptoms decreased (p < 0.001). On the second day (bandaged), supine diastolic BP values were higher in the persisting vs non-persisting PH group (p = 0.027). In the bandaged state, PH symptoms were significantly reduced in the non-persisting PH group (p = 0.003). Even in patients with persistent PH, the magnitude of BP decline and appearance of PH symptoms were decreased while wearing bandages (p - 0.004 and 0.002, respectively). Conclusion. During mobilization of inpatients, leg compression seems to reduce the seating-induced PH and relevant symptoms. Even in patients with persisting PH, bandaging may improve hemodynamics and attenuate associated symptoms.
