Electrodermal screening of biologically active points for upper gastrointestinal bleeding

Area of Science:

• Integrative Medicine
• Biophysics
• Gastroenterology

Background:

• Upper gastrointestinal bleeding (UGIB) is a significant clinical concern.
• Traditional diagnostic methods for UGIB can be invasive.
• Exploring non-invasive diagnostic markers is crucial.

Purpose of the Study:

• To investigate the relationship between skin electrical resistance at biologically active points (BAPs) and UGIB.
• To assess the diagnostic potential of electrodermal screening (EDS) for UGIB.

Main Methods:

• A case-control study involving 100 patients (with and without UGIB).
• Measurement of electrical resistance at 20 BAPs using electrodermal screening (EDS).
• Statistical analysis including ANOVA, ROC curve analysis, and logistic regression.

Main Results:

• Lower initial skin electrical resistance readings were observed in the UGIB group.
• Significant differences in indicator drop values were found at nine BAPs, particularly on the stomach and small intestine meridians (p < 0.05).
• Logistic regression indicated that increased indicator drop on the left stomach meridian significantly increased UGIB risk (1.545-3.523 times).

Conclusions:

• Changes in skin electrical resistance measured by EDS at BAPs on the stomach and small intestine meridians correlate with UGIB.
• EDS shows potential as a non-invasive diagnostic tool for identifying UGIB.
