Metoclopramide for Gastric Visualization in Active Upper GI Bleeding
- Conditions
- Upper GI Bleeding
- Interventions
- Drug: Normal Saline 10 mL Injection
- Registration Number
- NCT06167837
- Lead Sponsor
- King Chulalongkorn Memorial Hospital
- Brief Summary
This study aim to evaluate the efficacy of metoclopramide for gastric visualization in patients with active UGIB. This is a double-blinded, multicenter RCT. Patients with 'active' UGIB (hematemesis or presence of fresh blood in the nasogastric tube) were enrolled. The eligible patients were randomly assigned in a concealed 1:1 allocation to received either intravenous metoclopramide or placebo before endoscopy. The primary outcome was 'adequate visualization' by objective endoscopic visualized scores(EVS). Secondary outcomes included mean difference in total EVS and EVS at each location , duration of EGD, immediate hemostasis, need for a second look EGD, units of blood transfusion, length of hospital stay and 30-day rebleeding rate.
- Detailed Description
* This is double-blinded, multicenter RCT including six hospitals in Thailand.
* The participated endoscopists had work experience for endoscopy more than three years.
* All endoscopists at six participating sites attended the pre-study meeting for standardization of the protocol and scoring system.
* The primary outcome was 'adequate visualization' by objective endoscopic visualized scores(EVS). ; To assess overall endoscopic visualization, we estimated the coverage of a blood clot on mucosa in four locations including 1) gastric fundus, 2) corpus, 3) antrum and 4) duodenal bulb, according to the reference endoscopic views in protocal.
* All photos, including the reference endoscopic views, were taken and internally validated by another endoscopist who was blinded to the randomization allocation.
* This study includes pre-specified subgroup analysis by location of bleeding including gastric subgroup analysis.

- Primary Outcome Measures
Name Time Method Percentage of patients with 'adequate visualization' Through study completion, estimate 2 years 'adequate visualization' is determined by objective scoring method (endoscopic visualized scores (EVS) to estimate the coverage of a blood clot on mucosa in four locations including 1) gastric fundus, 2) corpus, 3) antrum and 4) duodenal bulb; At each location was assessed and scored between 0 and 2: 0, blood clot cover more than 75% of the surface ; 1, 25-75% blood clot coverage ; 2, blood clot coverage less than 25%. ; score \>=6 considered as adequate visualization
- Secondary Outcome Measures
Name Time Method Length of hospital stays 1day - 30days Length of hospital stays of participants
Duration of esophagogastroduodenoscopy 10minutes to 2 hours Immediate hemostasis Through study completion, estimate 2 years Rate of succession of hemostasis (bleeding stop) at first EGD
The mean difference in EVS Through study completion, estimate 2 years total of four locations and at each location including fundus, corpus, antrum and duodenal bulb
The need for a second look EGD within 72 hours after initial endoscopy Up to 72 hours Rate of need for a second look EGD within 72 hours after initial endoscopy The 72-hour recurrent GI bleeding was documented and re-EGD was performed to confirm rebleeding if the following conditions were met: I) hematemesis or bloody nasogastric tube (NG) \> 6 hours after endoscopy; II) melena after normalization of stool color; III) hematochezia after normalization of stool color or melena; IV) development of tachycardia (HR ≥ 110 bpm) or hypotension(SBP ≤ 90 mmHg) after ≥ 1 hour of vital sign stability without other cause; V) hemoglobin drop of ≥ 2 g/dL after two consecutive stable hemoglobin values ( \< 0.5 g/dL decrease) ≥ 3 hours apart; VI) tachycardia or hypotension that does not resolve within 8 hours after index endoscopy despite appropriate resuscitation (in the absence of an alternative explanation), associated with persistent melena or hematochezia or; VII) persistently dropping hemoglobin of \> 3 g/dL in 24 hours associated with persistent melena or hematochezia.
30-day rebleeding rate Up to 30 days rate of 30-day rebleeding of upper GI tract
Number of unit of red blood cell transfusion during first 24 hours Up to 24 hours Number of of unit of red blood cell transfusions during first 24 hours
