Sympathovagal Balance Fluctuates During Colonoscopy

Abstract: Most changes in HRV components occurred during colonoscopy of the left side of the bowel. Analgesia/sedation and total intravenous anesthesia increased HRV by increasing the LF component.

“…In the present study, midazolam seemed to potentiate the dominance of the sympathetic nervous system induced by the bronchscopic procedure. In fact, the same phenomenon has been reported during colonoscopy as well . This interesting controversy derives probably from the complex action of midazolam on the cardiovascular system, which includes both direct and indirect effects.…”

“…Allein die endoskopische Intubation des Kolons erzeugt beim unsedierten Patienten ein Übergewicht des sympathischen autoregulativen Nervensystems [334] und erhöht damit die Wahrscheinlichkeit für kardiovaskuläre Ereignisse. Der Einfluss auf die Herzfrequenzvariabilität wird aber durch eine Sedierung noch verstärkt[335]. Kardiopulmonale Ereignisse können aber auch bei unsedierten Patienten während der Gastroskopie beobachtet werden[336,337].4.4.2.2.…”
