氧化亚氮/氧吸入舒适化技术在老年高血压患者心电监护拔牙中的应用

目的: 探讨氧化亚氮/氧吸入舒适化技术在老年高血压患者心电监护拔牙中的应用价值。方法: 根据纳入、排除标准,将60例年龄>65岁的老年高血压拔牙患者随机分为2组（n=30）：试验组（氧化亚氮/氧吸入心电监护组）和对照组（常规心电监护组）,记录T0（术前基础值）、T1（局部麻醉）、T2（手术操作）、T3(术后5 min）4个时间点的平均动脉压（MAP）和心率（HR）。采用SPSS 25.0软件包对数据进行统计学分析。结果: 试验组组内MAP、HR各时间点比较均无统计学差异(P>0.05);对照组组内T0与T3时间点MAP、HR比较无统计学差异(P>0.05),其余各两两时间点MAP、HR比较均有统计学差异(P<0.05);组间比较,2组T0、T3时间点MAP、HR比较无统计学差异(P>0.05),2组T1、T2时间点MAP、HR比较,试验组显著小于对照组 (P<0.05)。结论: 氧化亚氮/氧吸入舒适化技术在老年高血压心电监护拔牙中能稳定患者情绪,维持患者血压、心率平稳,从而提高患者拔牙的安全性。

Application of nitrous oxide/oxygen inhalation comfort technique during tooth extraction of elderly hypertensive patients under electrocardiographic monitoring

PURPOSE: To investigate the application value of nitrous oxide/oxygen inhalation comfort technique during tooth extraction in elderly patients with hypertension under electrocardiographic(ECG) monitoring. METHODS: According to the inclusion and exclusion criteria, sixty elderly patients (over 65 years old) with hypertension for tooth extraction were randomly divided into 2 groups: the experimental group(nitrous oxide/oxygen inhalation combined with ECG monitoring group, n=30) and the control group (routine ECG monitoring group, n=30). Mean arterial pressure (MAP) and heart rate (HR) at T0 (baseline values before surgery), T1 (on local anesthesia), T2 (during operation) and T3(5 minutes after operation) were recorded. SPSS 25.0 software package was used for statistical analysis. RESULTS: There was no significant difference in MAP and HR at each time point in the experimental group(P>0.05). There was no significant difference in MAP and HR at T0 and T3 time points in the control group(P>0.05).At other time points, MAP and HR were significantly different (P<0.05). There was no significant differences in MAP and HR between the two groups at T0 and T3(P>0.05). MAP and HR at T1 and T2 in the experimental group were significantly less than those in the control group(P<0.05). CONCLUSIONS: Nitrous oxide/oxygen inhalation comfort technology can stabilize patients' emotions and maintain stable blood pressure and heart rate in elderly patients with hypertension during tooth extraction, thus improving the safety of tooth extraction.
