Abstract

Aim: Most button battery (BB) ingestions in children are unwitnessed leading to prolonged exposures and severe complications. One third of ingestions occur from free BB, that are stored or awaiting disposal. Recommendations have been made to cover the terminals of discarded BB with adhesive tape; however, it is unclear if this practice prevents injury. Our aim was to determine if tape could prevent oesophageal injury in a cadaveric porcine model.

Methods: Electrical, masking, packing and duct tape were compared. One BB was left untaped. Taped BBs were placed in a cadaveric porcine oesophagus controlled for temperature and humidification. Specimens were assessed at 0, 0.5, and hourly for 6 h by visual inspection, temperature and pH. BB voltage was measured before and after testing. All tests were repeated in triplicate.

Results: Oesophageal specimens demonstrated burn prevention in the packing and duct tape trials. Burns were seen in 2/3 trials with electrical tape and 3/3 trials with masking tape. pH remained neutral throughout the study for all packing and duct tape specimens. pH remained neutral initially for masking tape but increased rapidly to 12 by 2 h. There was no change in battery voltage for the packing tape and duct tape trials. There was a 16.3% reduction in voltage for masking tape which was similar to controls.

Conclusions: Taping BB with packing tape and duct tape prevented oesophageal burns. This may provide a novel method of burn prevention for loose BB intended for disposal.
