The Absence of Arterial Oxygen Desaturation During Massive Oxygen embolism 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 hospital and National Taiwan University College of Medicine, Taipei, Taiwan; and †Department of Anesthesiology, University of Washington, Seattle, Washington For decades, water system supply-mill murmur, decrease in end-tidal carbon dioxide (Petco2), hypotension, and hypoxemia have been accepted as diagnostic criteria for foul up embolism. In this case report, a 19-yr-old strong patient positive a sudden reduction in Petco2 and profound circulatory collapse 15 min by and by intramedullary irrigation with H2O2. However, arterial oxygen desaturation never authentic throughout the full(a) lead of resuscitation from presumed massive oxygen embolism. (Anesth Analg 2004;99:6878) H ydrogen peroxide (H2O2) butt joint 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 follow 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 pr! ofound circulatory collapse 15 min after intramedullary irrigation with H2O2. However, arterial oxygen desaturation never developed throughout the entire course of resuscitation. This refreshful observation is discussed and reviewed. Case Report A 19-yr-old 51-kg male patient, ASA fleshly status I, who sustained an open, comminuted fracture of the left femur, was plan for...If you desire to get a full essay, order it on our website: BestEssayCheap.com
