Meperidine need not be proscribed during sphincter of Oddi manometry.
Meperidine is routinely proscribed during sphincter of Oddi manometry because narcotics have been associated with spasm of the sphincter of Oddi. We have performed a prospective study of the effect of meperidine on sphincter of Oddi manometry in 18 patients undergoing manometry for suspected sphincter dysfunction. After diagnostic manometry using only intravenous diazepam sedation, the endoscope remained in the duodenum while 1 mg/kg intravenous meperidine was given. ⋯ Baseline sphincter pressure is generally the only manometric criteria used to diagnose sphincter dysfunction and this did not change after meperidine. We conclude that meperidine may be used for additional analgesia during sphincter manometry. This may improve patient tolerance and the success rate of this procedure.
