Autonomic nervous system function tests in patients with so-called shock

During otolaryngological treatment, our patients sometimes experienced so-called shock, such as neurogenic shock and psychogenic shock. The autonomic nervous system function of 29 patients who had a history of shock were examined. Twenty-seven patients (93%) had positive Schellong's test results. Five out of 7 patients had abnormal RR intervals on the ECG during the Schellong's test. Therefore the test battery of the Schellong's test and the RR intervals on the ECG before the examinations and treatments may make it possible to predict the occurrence of the so-called shock.
