Objective Evaluation of a New Epidural Simulator by the CompuFlo^® Epidural Instrument

Table 1

Differences in the mean values of false and true LOR (loss of resistance) between the drop of pressure observed with the simulator when compared to those of the controls.

Mean % of drop of pressure (mean, CI)	False LOR	True LOR (epidural space)
Simulator	9 (0.04–23)	97 (96–98)	0.04
Control	5.5 (2–13)	65 (63–75)	0.03
