Hydrogen peroxide (H2O2) is used by surgeons due to its oxygen releasing effervescent properties to locate internal openings in fistulous tracts. The oxygen released is known to cause embolism when it enters venous circulation, particularly when it is forced into a closed cavity. The obstruction it causes to the blood flow can cause circulatory and ventilatory failure. It manifests clinically by rapid fall in EtCO2, hypotension, rise in central venous pressure (CVP), and fall in oxygen saturation. We present a case of a male patient who underwent fistulectomy under a saddle block and later developed air embolism when H2O2 was forcefully pushed at the site of surgery.
