Metoclopramide for Gastric Visualization in Active Upper GI Bleeding

Phase 4
Recruiting
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
NameTimeMethod
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
NameTimeMethod
Length of hospital stays1day - 30days

Length of hospital stays of participants

Duration of esophagogastroduodenoscopy10minutes to 2 hours
Immediate hemostasisThrough study completion, estimate 2 years

Rate of succession of hemostasis (bleeding stop) at first EGD

The mean difference in EVSThrough 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 endoscopyUp 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 rateUp to 30 days

rate of 30-day rebleeding of upper GI tract

Number of unit of red blood cell transfusion during first 24 hoursUp to 24 hours

Number of of unit of red blood cell transfusions during first 24 hours
