TOMASICH, Flávio Daniel Saavedra et al. Experimental model obstructive jaundice: assessment by bioimpedance. Rev. Col. Bras. Cir. [online]. 2006, vol.33, n.1, pp. 15-18. ISSN 0100-6991.

BACKGROUND: The bioimpedance is method that has been used for body mass, liquid volume and body fat volume’s measurements. The authors observe the utilization and performance of the impedance in experimental research model of obstructive jaundice. METHODS: Eight Wistar rats were divided in two groups with four animals: experiment (1) and control (2). In the group (1) the rats underwent a ligated choledoco bile duct surgery, and in the group (2) the rats underwent laparotomy only. The resistance and reactance measurements had been accomplished by bioelectrical impedance analysis equipment in preoperative and postoperative procedures. RESULTS: The work denoted that the resistance’s mean values for group (2) were statistically significant higher than group (1). Also, the capacitive reactance’s average values were higher in the group (2) with p<0,0001. CONCLUSION: We conclude that in rats there are differences in the impedance’s values between groups, the resistance and capacitive reactance’s average values are lower in the experimental group.
