Summary
Optimal BICAP therapy for bleeding peptic ulcers involves high probe force and long coagulation times. Low generator output is recommended for effective arterial welding in this BICAP therapy application.
Area of Science:
- Gastroenterology
- Surgical Technology
- Biomedical Engineering
Background:
- Bleeding peptic ulcers are a significant clinical concern.
- BICAP therapy is an endoscopic hemostasis method.
- Optimizing BICAP parameters is crucial for effective treatment.
Purpose of the Study:
- To investigate the impact of various parameters on BICAP-induced arterial welds.
- To determine optimal settings for BICAP therapy in treating bleeding peptic ulcers.
Main Methods:
- In vitro study using rabbit arteries (3-5 mm hemicircumference).
- Varied probe force (94-491 g), coagulation time (2-20 secs), and generator output (5-10 W).
- Arterial welds tested to destruction via intraluminal pressure.
Main Results:
- Highest probe force and longest coagulation time yielded the strongest arterial welds.
- Increased BICAP generator output did not enhance weld strength.
- Optimal conditions involved high force, 20-second coagulation, and low generator output (≤5 W).
Conclusions:
- BICAP therapy for bleeding peptic ulcers should utilize maximal compression force.
- A minimum coagulation time of 20 seconds per site is recommended.
- Low BICAP generator output (≤5 W) is suggested for effective hemostasis.

Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.

785
Controlled current coulometry, also known as amperostatic coulometry, is a technique used in electrochemical analysis to measure the quantity of a substance through the controlled passage of current. It involves the application of a constant current to an electrochemical cell containing the analyte of interest. As the current flows through the cell, the analyte undergoes a redox reaction at the electrode surface, resulting in a charge transfer. By monitoring the time required for a certain...

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...
