Use of a portable syringe pump for glucagon administration in abdominal computed tomography

A portable syringe pump was used to administer glucagon by intravenous infusion in order to achieve bowel paresis during abdominal computed tomography. This technique produced a reduction in glucagon dosage and an improvement in scan quality when compared with intermittent intravenous injection. A smaller reduction in dosage with little change in scan quality was achieved with intramuscular infusion.
