The use of antispasmodic drugs during barium enemas

Abstract

In 1958, Welin recommended the routine use of atropine before a barium enema to reduce mucus secretion and make the examination more comfortable. Currently, many radiologists believe that smooth-muscle spasmolysis is a useful adjunct during a barium enema and use such a spasmolytic agent. One survey found that spasmolytic agents were administered more frequently in 1987 than in 1976. The use of glucagon had increased 20% between 1976 and 1987. Among 34 foreign institutions responding to the survey, 37% used glucagon and 45% used scopolamine butylbromide (Buscopan). Nevertheless, it is still controversial whether spasmolytic agents play a significant role in the performance and interpretation of a barium enema. Some radiologists routinely use a spasmolytic agent; others do so only selectively.
