Acute Gastrointestinal Bleeding Peripheral Pulse Volume Changes

Mayo Clinic

Status: Completed

Conditions: GastroIntestinal Bleeding

Treatments: Diagnostic Test: Pulse flowmeter

Study type: Observational

Identifiers

NCT06441201

Details and patient eligibility

About

The purpose and aim of this study are to compare changes in pulse volume to non-invasively predict active bleeding or high-risk stigmata in patients undergoing a gastrointestinal endoscopy to assess feasibility of the flow meter clinically.

Full description

The maximum change in volume of a limb segment during the cardiac cycle - pulse volume - will be monitored non-invasively along with standard vitals in patients with a suspected gastrointestinal bleed undergoing endoscopy. Pulse volume and vitals will be collected prior to and following endoscopy up to the point of dismissal from the endoscopy unit so that the data may be correlated with the endoscopic and clinical findings.

Enrollment: 13 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

- Adults (age >18yr) undergoing emergent endoscopy for active GI bleeding.

Exclusion criteria

• Patients with pre-existing heart failure (ejection fraction <40%), cardiac rhythm abnormalities and peripheral vascular disease.
• Patients with underlying implanted cardiac electrical devices and spinal cord stimulators.

13 participants in 1 patient group

Gastrointestinal Bleeding Peripheral Pulse Volume

Description:

Subject undergoing an emergency endoscopic evaluation for active gastrointestinal bleeding will have their peripheral pulse volumes monitored using a pulse flowmeter throughout the procedure and 2 hours after the procedure.

Treatment:

Diagnostic Test: Pulse flowmeter
