简要总结
Randomized controlled trial comparing haloperidol combined with conventional therapy and conventional therapy alone in patients with symptomatic gastroparesis.
详细描述
Study Design This study is a prospective, double-blind randomized placebo controlled trial involving adult emergency department (ED) patients who present with an acute exacerbation of gastroparesis. This study design will have two arms in the clinical trials. An experimental arm will receive an intravenous dose of haloperidol 5 mg in addition to conventional therapy, and the control arm will receive conventional therapy. Patients will be randomized as described below. Neither the physician nor the patient will be aware of the group to which the patient was randomized.
Methods Upon arrive at to the ED at the Memorial Hermann Hospital located in the Texas Medical Center; patients with gastroparesis (GP) exacerbation will be assessed for eligibility for enrollment in this trial by the clinicians on duty. Informed consent will be obtained from eligible patients that meet inclusion and exclusion criteria by trained ED residents. A 12 lead electrocardiogram will be performed to evaluate the presence of QT segment prolongation. Enrolled patients will be given 5 mg of intravenous haloperidol or equivalent volume of placebo pre-packaged and coded with a study ID number provided by the investigational pharmacy.
No unique identifiers or other PHI will be collected on enrolled patients. Information will also be recorded on the time elapsed from the time it took to provide the study medication and the time of the decision on disposition (admit or discharge). A record will be maintained if any additional medications including analgesics and antiemetics given to the patient before and after the study vial are given. Data will be collected on any adverse effects or complications the patients may experience (i.e. dystonic reactions, allergies etc.). After the data is collected at one hour for the primary outcome the trial will end and the physician will be unblended so they can choose subsequent medication.
All completed data collection forms will be dropped off in a secure locked mailbox and collected on a weekly basis by research staff. Collected forms will be housed in the ED office located in the Jesse Jones Library (JJL) 4th floor in a locked cabinet. Data will be entered electronically and analyzed using statistical package for the social sciences (SPSS) version 19.0. This database will be housed on a rights-protected research drive with limited access for viewing.
Informed Consent Patients will be notified of this study and they will be asked if they are interested in participating. If they are interested in participating, they will have the informed consent (IC) explained to them in either English or Spanish (Beaudoin, Nagdev, Merchant & Becker, 2010). The patient will sign, date, and put the time on the IC. The consenter will also do the same. A copy of the IC will be made in the ED and given to the patient for their records. The original copy will be housed in the regulatory binder located in JJL.

研究组 & 干预措施
Haloperidol plus Conventional Therapy
Intravenous dose of haloperidol 5 mg in addition to conventional therapy. Conventional Therapy includes hydration via IV fluids, pain control with analgesics (usually opiates) frequently requiring multiple doses, also antiemetics (often requires multiple doses and different agents in attempts to control nausea and vomiting within this population), in addition to electrolytes abnormalities corrections as needed.
干预措施: Haloperidol (Drug)
Conventional Therapy alone
Conventional Therapy includes hydration via IV fluids, pain control with analgesics (usually opiates) frequently requiring multiple doses, also antiemetics (often requires multiple doses and different agents in attempts to control nausea and vomiting within this population), in addition to electrolytes abnormalities corrections as needed.
干预措施: Conventional Therapy (Drug)
