The risk of electrical micro-shock is recognised in patients undergoing cardiac catheterisation or connected to electronic equipment instruments. The work reported here investigates the possibility of injury by electrical micro-shock when monitoring the central venous pressure as commonly done during surgical procedures. The studies were done on dogs catheterised for the measurement of central venous pressure with the catheter advanced into the right ventricle. It was found that currents less than 500 micro-amperes caused interference with heart rhythm, and in some of the dogs ventricular fibrillation developed. In view of these findings it appears that greater consideration should be given to the risk of electrical micro-shock in patients in whom the central venous pressure is measured.
接受心导管插入术或连接到电子设备仪器的患者存在微电击风险。本文报道的研究探讨了在外科手术过程中像通常那样监测中心静脉压时发生微电击损伤的可能性。研究是在通过插入导管测量中心静脉压且导管已推进到右心室的狗身上进行的。结果发现，小于500微安的电流会干扰心律，并且在一些狗身上出现了心室颤动。鉴于这些发现，似乎对于测量中心静脉压的患者，应更多地考虑微电击风险。
