The Hemodynamic Response to Traction on the Abdominal Mesentery

Reflex bradycardia during surgery

“…The accompanying decrease in heart rate was only minor, apparently due to the compensatory effects of the Bainbridge reflex (an increase in heart rate resulting from an increase in the pressure within the large veins or the right atrium). 3 More recently, Seltzer et al 4 observed that traction on the abdominal mesentery resulted in a decrease (20 mmHg on average) in mean arterial pressure, which was attributed to vasodilatation, manifested as a decrease in systemic vascular resistance, as measured using invasive haemodynamic monitoring. This was often accompanied by an increased heart rate, although instances of bradycardia also occurred.…”

Comparison between endoscopic and surgical sampling for the measurement of potential doubling time in colorectal cancer

“…In particular, anesthetic and surgical conditions could influence kinetic parameters. Hemodynamic changes during anesthesia and the time from vascular ligature to tumoral sampling could decrease the energy supply in the tumor and slow kinetics (16). However, other parameters such as TIB could also influence the T pot determination.…”

Comparison of effects of rocuronium bromide versus vecuronium bromide on hemodynamic parameters during anaesthesia for elective surgical procedures

“…Anaesthesia has tendency to produce significant hemodynamic changes especially during induction and intubation. Also many of the factors like reflex vagal activity during surgeries like strabismus surgery, laparotomy 1,2 and concurrent use of various anaesthetic agents can significantly alter hemodynamics during the course of anaesthesia. So, hemodynamic effects of the drug remain important criteria while selecting neuromuscular blocking agent during anaesthesia especially in selected cases where maintaining hemodynamic parameters within specified range is critical.…”
