Making post-mortem implantable cardioverter defibrillator explantation safe

Aims The aim of this study is to investigate whether protection with rubber or plastic gloves during post-mortem explantation of an implantable cardioverter defibrillator (ICD) offers enough protection for the explanting operator during a worst-case scenario (i.e. ICD shock). Methods and results We investigated the insulating properties of rubber and plastic gloves (double layer) within the first 60 min exposure (mimicking the maximum time of an explantation procedure) to saline (simulating the effects of body fluids on the gloves). For latex gloves, we measured an increase in voltage up to 68.1 V ( P < 0.0001), for neoprene a maximum voltage of 5.3 V ( P = 0.245), and for plastic a voltage of 2.3 V within the first hour. If the exposure time to fluid did not exceed 50 min, a double pair of intact gloves made of latex, neoprene, or plastic constituted such a large resistance that the resting voltage over the operating person would not exceed 50 V. Conclusion The use of intact medical gloves made of latex, neoprene, or plastic eliminates the potential electrical risk during explantation of an ICD. Two gloves on each hand offer sufficient protection. We will recommend the use of neoprene gloves.
