High compression leg bandaging prevents seated postural hypotension among elderly hospitalized patients

Postural hypotension (PH) is a very common and often symptomatic disorder among elderly hospitalized patients. Little is known about measures for preventing previously unknown PH in this population. We evaluated the effectiveness of high compression leg bandaging in preventing seated PH during the initial phase of ambulation, among elderly inpatients without a history of PH. We compared the occurrence of seated PH between patients who were bandaged (n = 100) and unbandaged (n = 100). The rate of seated PH was significantly lower in the bandaged than the unbandaged group (27% vs. 51%, p < 0.001, relative risk reduction 47%, and the number of patients needed to treat 4.2). On multivariate analysis, not wearing leg bandaging was one of the variables most significantly associated with eventual occurrence of PH (p = 0.002, odds ratio 2.65, and 95% confidence interval 1.42−4.97). We conclude that during ambulation of elderly inpatients, high compression leg bandaging is beneficial to prevent seated PH.
