During a coronary artery bypass operation arterial blood pressure measured with a Bentley Trantec model 800 transducer increased erroneously while continuous electrocautery was being used. This phenomenon has recurred infrequently, with fictitious hypotension being observed in one patient. To reproduce the problem of pressure offset during electrosurgery a bench test demonstrated that with peak to peak voltage of 20 volts from the electrosurgical unit, three of seven Bentley transducers had offsets as much as +/- 50 mmHg. It is important for anaesthetists to determine if electrosurgery units are functioning before treating apparent pressure drifts.
在冠状动脉搭桥手术期间，使用Bentley Trantec 800型传感器测量动脉血压时，在使用连续电灼术期间血压出现错误升高。这种现象偶尔会再次出现，有一名患者出现了假性低血压。为了重现电外科手术期间压力偏移的问题，一项台架试验表明，当电外科设备的峰峰值电压为20伏时，七台Bentley传感器中有三台的偏移量高达±50 mmHg。麻醉医生在处理明显的压力漂移之前，确定电外科设备是否正常工作非常重要。
