Lidocaine (60 mg/100 ml) was added to contrast medium (120 ml of Conray-60) in an attempt to decrease pain associated with leg venography in 100 patients. No side effects were seen, and there was a marked reduction in pain as reported by four different examiners in two separate hospital populations.
