Radiculography: is routine bed rest really necessary?

Clin Radiol. 1983 May;34(3):325-6. doi: 10.1016/s0009-9260(83)80350-x.


After undergoing metrizamide radiculography, 119 patients were randomly allocated to two groups, one group remaining ambulant and the other being kept in bed for 24 h. A member of staff who did not know the category allocation questioned each patient regarding the occurrence of side-effects 24 and 48 h after the procedure. It was found that the incidence and severity of complications was neither increased nor decreased by allowing the patient to remain ambulant.
