Large volumes of fluid have been recommended to aid rapid ipecac-induced emesis, however, large volume intake may also have deleterious effects. We prospectively studied 121 children treated at home by a regional poison center to determine if a relationship existed between fluid volume and time to emesis. These children were treated in the usual manner except that parents were asked to measure the volume of fluid given and to note the time that fluid was given and the time of first emesis. The time ranged from 6 to 58 minutes (mean 20.6) with two who failed to respond and the volume ranged from 0 to 28 ounces (mean 6.7 ounces). In children who respond to ipecac, there is no significant relationship between the amount of fluid given and the time until emesis. We conclude that the traditional recommendation of forcing fluid with syrup of ipecac does not hasten emesis in children.
