To study the effects of cardiovascular function in dental extraction on hypertensive patients by inhalation 50% nitrous oxide.
The 30 hypertensive patients were randomly allocated into two groups: A group inhalation the 50% nitrous oxide and oxygen, B group inhalation the air and O(2). To measured the HR, BP, and SpO(2) in dental extraction.
In a group the changes of blood pressure and heart rate are more smoother than B group. Two groups were significant in HR, BP and SpO(2) (P < 0.01).
Inhalation with 50% nitrous oxide can keep the stability of cardiovascular system and it is a valid method in dental extraction on hypertensive patients.
研究50%氧化亚氮吸入用于高血压患者拔牙时对心血管功能的影响。
将30例高血压患者随机分为两组：A组吸入50%氧化亚氮和氧气，B组吸入空气和氧气。在拔牙时测量心率（HR）、血压（BP）和脉搏血氧饱和度（SpO₂）。
A组血压和心率变化较B组更平稳。两组在HR、BP和SpO₂方面差异有统计学意义（P<0.01）。
50%氧化亚氮吸入可维持高血压患者拔牙时心血管系统的稳定，是一种有效的方法。
