COVID-19 lockdown led to fewer ingestion cases but a higher percentage of more serious cases needed hospitalisation

Button battery taping prevents oesophageal injury

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.

Disc battery ingestion in paediatric age

AIM

The aim of the present study was to analyse clinical data of children referred for disc battery ingestion in order to assess short- and long-term reported injuries and to identify outcome predictors and trends, define the urgency of intervention and refine treatment guidelines.

METHODS

The records of all children admitted to Santobono-Pausilipon Children's Hospital, Naples, Italy for disc battery ingestion from January 2016 to December 2020 were retrospectively reviewed. Odds ratio were computed to assess the association between the different study variables and the rate of complications.

RESULTS

We enrolled 118 children. Mild to major complications related to the ingested disc batteries were reported in 12/118 (10.2%) patients. Disc battery oesophageal retention, disc battery diameter >20 mm, together with age below 1 year and symptomatic presentation were the most important factors associated with poor clinical outcome.

CONCLUSION

Our data confirm that ingested disc batteries are a serious health hazard and require a timely and qualified medical evaluation. We have identified three predictors of outcome severity: oesophageal retention, large-diameter cells and symptom onset. Disc batteries lodged beyond the oesophagus appear substantially harmless and we may support a more conservative approach.
