摘要

Objective: Rabbits are more prone to hypotension under anesthesia causing high mortality. Effectively monitoring blood pressure has been shown to reduce such anesthesia‐related mortality. The median auricular artery may be an appropriate artery for monitoring invasive blood pressure. However, there are still few studies on evaluating the practicality of monitoring blood pressure by median auricular artery. Our study is to determine the efficacy of monitoring blood pressure by this artery and to investigate the normal range of blood pressure in rabbits. Methods: A 24 G intravenous catheter was placed in the median auricular artery of rabbits after anesthesia, and invasive arterial blood pressure was measured by a calibrated pressure transducer. Results: Vital signs measured at different times show no statistical difference in repeated measures of anova. Under anesthesia, the normal range of central auricular artery blood pressure is 77.74(63.61 ~ 91.87)/58.57(45.22 ~ 70.69)mmHg. Conclusion: The median auricular artery is a reliable and feasible method for monitoring invasive arterial blood pressure.
