Gas Embolism After Hydrogen Peroxide Use During Spine Surgery: Case Report and Literature Review.

Abstract

As an irrigant, an antiseptic, and a hemostatic agent, hydrogen peroxide (H₂O₂) is widely used in surgical treatment, but it has been surrounded by persistent controversy. Fatal or near-fatal embolic events caused by H₂O₂ have been reported sporadically in spine surgery. In this report, we present an 87-year-old man who underwent lumbar instrumentation removal and debridement consequent to surgical site infection in a prone position. H₂O₂ was used to irrigate the infected screw tracks and surrounding tissues during the procedures. Soon after irrigation, the patient suddenly developed tachycardia, hypotension, and rapid oxygen desaturation, followed by bradycardia. Transesophageal echocardiography indicated gas embolism. After prompt first aid treatment, the patient's condition improved and the gas embolus disappeared within a few minutes without any evidence of organ embolism. Spine surgeons should reconsider the pending results of using H₂O₂ during surgery. Prolonged prone positioning and semiclosed cavities may increase the risk of gas embolism. An early diagnosis and timely intervention may be the key measures to prevent the occurrence of fatal consequences caused by gas embolism.
