超前视听分散干预在PPH术中的应用研究

Application of Advanced Audio-visual Dispersion Intervention in PPH

目的:研究超前视听分散干预痔上黏膜环切术(PPH)中血管迷走神经反射(VVR)的临床作用。方法:将本院2017年9月至2019年9月收集到的100例进行PPH的患者采取简单随机分组方式分为两组:试验组50例,对照组50例。试验组采用超前视听分散术干预,各组术中均给予阿托品和视听分散预防术中血管迷走神经反射发生。对比试验组和对照组预防术中发生血管迷走神经反射的数据。结果:试验组2%(1/50)发生VVR,低于对照组16%(8/50),比较结果显示差异有统计学意义(P<0.05)。记录术前30min两组平均心率(HR)、动脉压(MAP)等数据,水平比较结果显示差异无统计学意义(P>0.05)。PPH击发时对照组MAP、HR水平较进术前明显下降(P<0.05),而且相比于试验组降幅得更大(P<0.05)。术后30min两组MAP和HR水平及组间比较,结果显示差异无统计学意义(P>0.05)。结论:超前视听分散技术能减少PPH患者围手术期的VVR。

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.
