OBJECTIVE: This article tests the protective effect of a commercially available mixture of hyaluronic acid, chondroitin sulfate, and poloxamer 407 on the damage caused by the exposure of esophageal mucosa to button batteries in an animal model.
METHODS: Experimental study. Sixty porcine esophageal samples were distributed in three groups: control (CG), exposure (EG), and exposure-protection (EPG). In EG and EPG, one CR2032 button battery per sample was inserted, both were subdivided into 2-, 4-, 6-, and 24-hour exposure subgroups, with subsequent battery removal. EPG samples were irrigated with the solution 1 hour after battery exposure. Esophageal pH and final voltage of the battery were measured.
RESULTS: pH in CG remained stable. No significant differences in pH at 1 hour were found between EG and EPG. In EPG, the pH of the mucosa exposed to the anode was lower than in GE at 2 hours (12.44 vs. 11.89, p = 0.203) and 4 hours (13.78 vs. 11.77, p < 0.0001). In the cathode pH was significantly higher in EG at 2 hours (2.5 vs. 4.11, p < 0.0001), 4 hours (2.33 vs. 4.78, p < 0.0001), and 6 hours (2.17 vs. 2.91, p < 0.0001). Significant voltage reduction at 1 hour was found in EG compared to EPG (0.48 vs. 1.08 V, p = 0.004).
CONCLUSION: Exposure to hyaluronic acid solution buffers the acidification on the side exposed to the cathode and basification on the anode. This effect can be maintained up to 3 to 5 hours, even after stopping its application. Our results suggest that a solution containing hyaluronic acid could be used as an esophageal protector after accidental ingestion of button batteries.
