The Absence of Arterial Oxygen Desaturation During Massive Oxygen intercalation After Hydrogen Peroxide Irrigation Wei-Zen Sun, MD*, Chin-Shuang Lin, MD*, Andy A. Lee, MD†, and Wei-Hung Chan, MD* *Department of Anesthesiology, subject area Taiwan University infirmary and National Taiwan University College of Medicine, Taipei, Taiwan; and †Department of Anesthesiology, University of Washington, Seattle, Washington For decades, weewee supply-mill murmur, decrease in end-tidal carbon dioxide (Petco2), hypotension, and hypoxemia have been accepted as diagnostic criteria for assail embolism. In this case report, a 19-yr-old unshakable patient positive a sudden reduction in Petco2 and profound circulatory collapse 15 min later intramedullary irrigation with H2O2. However, arterial oxygen desaturation never positive throughout the full(a) production line of resuscitation from presumed massive oxygen embolism. (Anesth Analg 2004;99:6878) H ydrogen peroxide (H2O2) raft be hazardous when irrigated into the stomach (1,2), subcutaneous tissue (3), or open wounds (4). Catabolism of H2O2 produces oxygen and water; 1 mL of 3% H2O2 releases approximately 10 mL of oxygen (5). When the cadence of oxygen exceeds its maximal blood solubility, venous embolization occurs. For decades, watermill murmur, decreases in end-tidal carbonic acid gas (Petco2), hypotension, and hypoxemia have been accepted as specimen diagnostic criteria for gas embolism (6 8) and have occurred in former reports after H2O2 irrigation (1 4). In this case report, we present a young, goodish patient who developed a sudden reduction in Petco2, murmurs, and profound circulatory collapse 15 min after intramedullary irrigation with H2O2. However, arterial oxygen desaturation never developed throughout the entire course of resuscitation. This tonic observation is discussed and reviewed.
