Peptic Ulcer, Peptic Ulcer, Acute With Hemorrhage, Peptic Ulcer Hemorrhage, Proton Pump Inhibitor Overdose
Conditions
Brief summary
We prepare this study to compare the efficacy of intermittent intravenous PPI infusion (relatively low dose PPI therapy) than continous PPI infusion method. Our hypothesis is that intermittent (40mg as a bolus injection daily for 72 hours) PPI therapy is not inferior to conventional high dose therapy.
Detailed description
Background Current guidelines recommend an intravenous bolus dose of a proton pump inhibitor(PPI) followed by continuous PPI infusion after endoscopic therapy in patients with high-risk peptic ulcer bleeding. However, intermittent PPI have not been inferior to continuous PPI infusion regimens in recent studies. Objective The aim of this study was to compare the effect of intermittent (40mg as a bolus injection daily for 72hours) versus continuous (40mg as a bolus injection followed by continuous infusion at 8mg/hr for 72hours) intravenous pantoprazole for prevention of bleeding after endoscopic therapy of peptic ulcer bleeding. Also, the same comparison was performed in high-risk patients (Rockall scores ≥6). Methods This single center cross-sectional study was conducted from january 2010 through december 2013. Patients who presented with overt or suspected upper gastrointestinal bleeding based on hematemesis and/or melena were eligible. These eligible patients were required to have a peptic ulcer with bleeding on emergency endoscopy performed within 24 hours after hospitalization. Exclusion criteria were refusal of endoscopy, gastrointestinal malignancy, Mallory-Weiss syndrome, variceal bleeding, bleeding d/t endoscopic procedure, small bowel bleeding, serious medical disease, etc. Demographic and medical data were obtained from the patients' medical records. Current or past history of medical diagnosis and drug history were also recorded. Statistical analysis performed using SPSS 21.0 software.
Interventions
DRUGintermittent (40mg as a bolus injection daily for 72hours)
Current guidelines recommend an intravenous bolus dose of a proton pump inhibitor(PPI) followed by continuous PPI infusion after endoscopic therapy in patients with high-risk bleeding peptic ulcers. However, recent many studies suggests intermittent low dose PPI infusion might have equal efficacy at preventing peptic ulcer hemorrhage recurrence. So, the present investigator assumed that intermittent administration of proton pump inhibitor will not be different from administration of continuous proton pump inhibitor for the prevention of rebleeding in patients with peptic ulcer bleeding. Also, intermittent proton pump inhibitor administration in patients with high risk of rebleeding (Rockall score 6 points or more) will not be different from prevention of rebleeding compared with continuous proton pump inhibitor administration.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| rebleeding rates within 7 days | Within 7 days from enrollment of patient | Rebleeding was defined that endoscopy confirms that the bleeding is completely controlled and the following outcomes occur after initial vital signs are stabilized. 1. when a new hematemesis, hematochezia, occurs. 2. melena occurs and blood pressure decreases (less than 90 mmHg) or pulse rate increase (110 beats per minute) or hemoglobin decline (greater than 3 g / dL) within 24 hours. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Transfusion requirement | within 7 days from enrollment of patient | The amount of transfusion that occurred during the period when the patient was in hospital was recorded as unit. |
| Hospital stay | within 1 years from enrollment of patient | length of hospital stay - From the day the patient visits the emergency room to the day when the patient gets discharged |
| Death related with Upper GI bleeding | within 1 years from enrollment of patient | All-cause or bleeding-related mortality was observed within 1 year of patient enrollment. |
| Operation d/t Upper GI bleeding | within 1 years from enrollment of patient | This result is defined as exploratory laparatomy associated with peptic ulcer bleeding, gastric and duodenal resection anastomosis, and vagotomy. |
