    Abstract:
    STUDY OBJECTIVE: Ingestion of diatrizoate meglumine before abdominal computed tomography (CT) is time consuming. We hypothesized that pretreatment with metoclopramide or ondansetron would result in faster ingestion of diatrizoate meglumine than placebo. METHODS: The study was a double-blind, randomized controlled trial on adults requiring oral contrast abdominal CT. Patients were randomized to placebo, metoclopramide 10 mg, or ondansetron 4 mg intravenously 15 minutes before ingesting 2 L of diatrizoate meglumine. The primary outcome was time to complete diatrizoate meglumine ingestion. Secondary outcome measures included volume of diatrizoate meglumine ingested, 100-mm visual analog scale for nausea at 15-minute intervals, time to CT, vomiting, and use of rescue antiemetics. The study was powered to detect a 60-minute difference in diatrizoate meglumine ingestion time between saline and medication groups. RESULTS: One hundred six patients were randomized; placebo (36), metoclopramide (35), and ondansetron (35). Groups were similar in baseline characteristics. Median (interquartile range) times for diatrizoate meglumine ingestion were placebo 109 minutes (82 to 135 minutes); metoclopramide 105 minutes (75 to 135 minutes); and ondansetron 110 minutes (79 to 140 minutes) (P=.67). Vomiting was less frequent with metoclopramide (3%) than placebo (18%) or ondansetron (9%) (P=.11). The visual analog scale for nausea at each point was not significantly different between groups (P=.11). The need for rescue antiemetics was lowest for metoclopramide (3%) compared with placebo (27%) and ondansetron (12%) (P=.02). CONCLUSION: Pretreatment with ondansetron or metoclopramide does not reduce oral contrast solution ingestion time.
