Cardiovascular reflexes elicited by passive gastric distension in anesthetized cats

alpha-chloralose anesthetized cats

Passive gastric distension with 37 degrees C fluid at slow (50 ml/min) and rapid (250 ml/min) infusion rates before and after laparotomy, and with vagus or splanchnic nerve section

Baseline (before distension)

Hemodynamic responses including mean arterial pressure (MAP), dP/dt at 40 mmHg developed pressure, systemic vascular resistance (SVR), heart rate, aortic flow, and left ventricular end-diastolic pressuresurrogate
