title: Hemodynamic parameters of anesthetized pigs: a comparative study of farm piglets and Göttingen and Yucatan miniature swine.
abstract: We studied the evolution in time of the main hemodynamic parameters in farm piglets and Göttingen and Yucatan miniature swine anesthetized with droperidol, flunitrazepam, and alpha-chloralose. Measurements included arterial pressure, heart rate, intraventricular pressure, and maximum rate of increase during contraction (dp/dt max). For each parameter and each strain of swine, we determined the mean stability period defined as the longest period of time during which the observed values ranged between their mean value +/- 15% and the mean absolute values during the stability period. In our experimental conditions, the parameters remained constant for 2 to 3.5 hours. Only minor interstrain variations were noticed.
