Third-degree burns associated with transcutaneous pacing.

A 69-year-old severely obese diabetic woman developed nausea, vomiting and diarrhoea which caused multiple metabolic alterations leading to hypotension and bradycardia due to slow atrioventricular junctional rhythm. Transcutaneous pacing (TCP) was initiated and maintained until the underlying heart rate and blood pressure normalised. TCP gel pads were kept in place prophylactically after pacing was terminated. Gel pads remained attached to the anterior thorax and back for a total of 36 hours. During this time the patient developed third-degree burns at the side of gel pad attachment. With appropriate wound care and after a long hospitalisation, the patient was discharged in stable condition. This case demonstrates that prolonged use of TCP gel pads without frequent replacement may lead to third-degree burns. It also suggest that prophylactic use of TCP gel pads should be avoided.
