在关节镜肘部手术中的射频切除 (RFA) 与灌是安全的. 没有灌的连续使用应限制在3秒内,以防止部神经附近的危险温度升高.
科学领域:
- 整形外科手术 整形外科手术
- 最少侵入性手术的方法
- 生物医学工程 生物医学工程
背景情况:
- 关节镜外科手术越来越多地被利用,因为它具有最小的侵入性益处.
- 肘部关节镜术带来了独特的挑战和潜在的风险.
- 在射频剥离过程中调查热效应对于患者安全至关重要.
研究的目的:
- 在关节镜外科手术中,在射频切除过程中评估肘部关节的温度发展.
- 评估无线电频率剥离对热传播的安全性.
- 为了确定在肘部关节镜术中射频切除的安全使用参数.
主要方法:
- 尸体肘部模型 (n=7) 经历了关节镜手术,用后侧,横侧和前侧方法进行.
- 双极无线电频率切除 (bRFA) 应用于特定位置,有或没有灌.
- 温度探针监测了关节温度,特别是在大脑沟和部神经附近.
主要成果:
- 无灌的射频剥离会在5秒内导致关节内温度迅速升高.
- 在没有灌的情况下,在olecranon fossa中观察到显著的温度升高 (p=0.0052).
- 在持续灌的情况下,神经附近的温度在30秒内保持在41°C以下 (p=0.0747).
结论:
- 无线电频率切除是安全的肘部关节镜检查,当使用连续灌.
- 不灌的射频除应仅限于3秒的应用.
- 射频除的热效应不太可能对部神经产生不利影响,尽管部神经靠近.

Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
