Intravenous haloperidol for the treatment of intractable vomiting, cyclical vomiting, and gastroparesis

Secondary outcomes of interest were opioid analgesic administration calculated using morphine equivalent doses of analgesia (http://www.medcalc.com/narcotics.html), the intensity of abdominal pain recorded on a scale of 1 to 10 at triage and at time of disposition, and ED length of stay. The outcome of reduced hospitalization rate in the IV HP group was prominent (odds ratio [OR] 0.083, 95% confidence interval [CI] 0.002-0.563, P=0.004). [14] In fact, the authors of a meta-analysis comprising 21 randomized controlled trials based on more than 3,000 patient visits calculated that cardiac dysrhythmias occurred in 0.21% of cases in which a dose of 5 mg of IV HP was administered. The study site is in a metropolitan area with a variety of secondary and tertiary hospitals, so it was possible that we did not capture all ED visits by the patients who met our inclusion criteria.
