[Automatic monitoring of the myoelectric activity of the small intestine in peritonitis].
To monitor small intestinal myoelectrical activity in patients with peritonitis, the authors used direct electromyography. While processing the electromyograms, they calculated the frequency and amplitude of complexes, the standard deviation of complex duration, the amplitude of spike potentials and spike activity. Data on 41 patients were analyzed by using statistical methods. Normal value ranges and their variations in good- and poor- prognosis peritonitis were established. The findings were used to develop an automatic system which may enter an electromyogram, process it in automatic and semi-automatic modes, store the numbered curve and calculations in special files, construct a chart of the power spectrum density of a signal by the fast Fourier transform.
