RU2319442C2 - Method for recording gastrointestinal tract motor activity - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: method involves placing human body into bath and recording acoustic oscillations of anterior abdominal wall in liquid by means of sensor unit held 0.05-0.15 times L far from body surface, where L is the bath length. Low frequency oscillations are recorded. The oscillations having frequency of 0.04-0.06 Hz, stomach motor activity is stated. The frequency being equal to 0.1=0.3 Hz, thin intestine activity is stated, the value being equal to 0.4-0.6 Hz, large intestine activity is stated.

EFFECT: high accuracy in recording motor activity.

Description

The invention relates to medicine and can be used as a method of recording motor activity of the gastrointestinal tract.

There is a method of intragastric pH metering with the possibility of detecting movements of the stomach (Pantsyrev Yu.M. et al. Intragastric pH meter in a surgical clinic. M., 1972.) (1). This method is taken as an analog.

A known method for assessing the motor activity of the organs of the gastrointestinal tract by recording electromotor activity in an acute and chronic experiment using implanted immersion electrodes (Vasiliev V.A. et al. Assessment of the motor activity of the organs of the gastrointestinal tract. Ross. Gastroenterol. Hepatol. Coloproctol. 1995, No. 4, p. 48-54.). - (2) - prototype.

The known method has relatively limited accuracy in registering the motor activity of the gastrointestinal tract in humans.

The aim of the invention is to improve the accuracy of registration of motor activity of the gastrointestinal tract.

The technical result is achieved by the fact that a person’s body is immersed in a bath and acoustic vibrations of the anterior abdominal wall are recorded in the fluid volume using a sensor placed at a distance of 0.05-0.15 L from the body surface, where L is the length of the bath, and low-frequency signals are recorded fluctuations and with the value of these fluctuations 0.04-0.06 Hz indicate the motor activity of the stomach, with a frequency of 0.1-0.3 Hz - of the small intestine and with a frequency of 0.4-0.6 Hz - of the colon.

The method is implemented as follows.

After hygiene procedures, the patient is placed in a bathtub filled with water at a temperature of 32-35 ° C. Water completely covers the subject's chest, abdomen, and thighs. The patient is brought into a state of psycho-emotional rest. In the bath, at a distance of 0.05-0.15 L from the surface of the body, where the L-linear dimension of the length of the bath, an acoustic vibration sensor is placed. The sensor is connected to blocks of filtering, amplification, registration, computer processing of the recorded signal and video monitoring. The vibrations associated with the contraction of the heart and lungs are filtered out.

Carry out mathematical processing of the recorded signal according to the Fourier transforms.

Low-frequency oscillations are recorded. The vibrations associated with the contraction of the heart and lungs are filtered out. Record the received data on the hard disk of the computer and on paper. With a value of low-frequency fluctuations of 0.04-0.06 Hz, the motor activity of the stomach is observed, with a frequency of 0.1-0.3 Hz - of the small intestine and with a frequency of 0.4-0.6 Hz - of the colon.

The method is further explained by examples of its implementation.

Example 1

Patient M., 32 years old, was admitted with complaints of periodically occurring constipation, followed by diarrhea. Objectively: the abdomen is painless on palpation, coprological examinations - without features. After performing hygienic procedures, the patient is placed in a bathtub filled with water at a temperature of 32 ° C. Water completely covers the subject's chest, abdomen, and thighs. The patient is in a state of psycho-emotional rest. In the bath at a distance of 0.05 L from the surface of the body, where the L-linear dimension of the length of the bath, place the sensor of acoustic vibrations. The sensor is connected to blocks of filtering, amplification, registration, computer processing of the recorded signal and video monitoring. The vibrations associated with the contraction of the heart and lungs are filtered out.

Carry out mathematical processing of the recorded signal according to the Fourier transforms.

Low-frequency oscillations are recorded. The vibrations associated with the contraction of the heart and lungs are filtered out. With a value of low-frequency fluctuations of 0.04 Hz, the motor activity of the stomach is ascertained, with a frequency of 0.1 Hz — of the small intestine, and with a frequency of 0.4 Hz — of the colon.

Example 2

Patient K., 39 years old, upon admission complains of abdominal pain, periodically occurring constipation. The patient is placed in a bathtub filled with water at a temperature of 33 ° C. Water completely covers the subject's chest, abdomen, and thighs. The patient is in a state of psycho-emotional rest. In the bath at a distance of 0.1 L from the surface of the body, where the L-linear dimension of the length of the bath, place an acoustic vibration sensor. The sensor is connected to blocks of filtering, amplification, registration, computer processing of the recorded signal and video monitoring. The vibrations associated with the contraction of the heart and lungs are filtered out.

Low-frequency oscillations are recorded. The vibrations associated with the contraction of the heart and lungs are filtered out. Carry out mathematical processing of the recorded signal according to the Fourier transforms. Oscillations are recorded with a frequency of 0.05 Hz, which indicates the motor activity of the stomach, a frequency of 0.2 Hz for the small intestine and a frequency of 0.5 Hz for the colon. The results obtained are used in the appointment of prokinetics. After a course of treatment, a study of the motor activity of the patient’s gastrointestinal tract is repeated. The following indicators were obtained: the motor activity of the stomach increased after treatment to 0.06 Hz, the small intestine to 0.25 Hz, the colon to 0.6 Hz. There are no complaints of constipation, pain disappeared.

Example 3

Patient Z., 45 years old, was admitted with complaints of recurring diarrhea. According to an objective examination, the abdomen is painless on palpation, the analysis of feces for dysbiosis is without features. The patient is placed in a bath filled with water at a temperature of 35 ° C. The patient is in a state of psycho-emotional rest. In the bath at a distance of 0.15 L from the surface of the body, where the L-linear dimension of the length of the bath, place the sensor of acoustic vibrations. The sensor is connected to blocks of filtering, amplification, registration, computer processing of the recorded signal and video monitoring. The vibrations associated with the contraction of the heart and lungs are filtered out.

Low-frequency oscillations are recorded. The vibrations associated with the contraction of the heart and lungs are filtered out. With a value of low-frequency fluctuations of 0.06 Hz, the motor activity of the stomach is ascertained, with a frequency of 0.3 Hz - of the small intestine and with a frequency of 0.6 Hz - of the colon.

The results obtained are used in the selection of drug therapy. After a course of treatment, a study of the motor activity of the patient’s gastrointestinal tract is repeated. The following indicators were obtained: the motor activity of the stomach decreased after treatment to 0.05 Hz, the small intestine to 0.2 Hz, the colon to 0.5 Hz. There are no complaints of diarrhea. The conclusion is drawn about the success of the treatment.

In 17 patients, the inventive method for registering the motor activity of the gastrointestinal tract was reproduced and an increase in the accuracy of registration was confirmed.
