Abstract Objective: To study the clinical effect of advanced audio-visual dispersion on vasovagal reflex (VVR) in hemorrhoidectomy (PPH). Methods: 100 patients with HHP from September 2017 to September 2019 were randomly divided into two groups.Both groups were given atropine and VVR during the operation, and the experimental group was intervened by advanced audio-visual dispersion. The preventive effect of the two groups on intraoperative VVR was compared. Results: VVR occurred in 2% (1 / 50) of the experimental group, which was lower than 16% (8 / 50) of the control group. The comparison results showed that the difference was statistically significant (P<0.05). The average heart rate (HR), arterial pressure (map) and other data of the two groups 30 minutes before operation were recorded. The level comparison results showed that there was no significant difference (P>0.05). The levels of map and HR in the control group were significantly lower than those before operation (P<0.05), and the decrease was greater than that in the experimental group (P<0.05). There was no significant difference in map and HR levels between the two groups 30 minutes after operation (P>0.05). Conclusion: Advanced audio-visual dispersion technology can reduce the VVR in the perioperative period of PPH patients.
