Authors report a case of air-embolism and subsequent ischaemic damage to the brain following intra-operative irrigation with hydrogen peroxide within a closed cavity of a spinal cold abscess of tuberculous origin. Copious amount of undiluted hydrogen peroxide irrigation was deployed under moderate pressure to clean-up the abscess cavity. Post-operatively, the patient developed seizures followed by clinical and radiological features of brain ischaemia ultimately resulting in a fatal outcome. The authors reflect on the events, review the relevant literature regarding intra-operative use of hydrogen peroxide in cranio-spinal procedures, outline mechanism of its actions, and highlight its disadvantages and potential complications.
