ABSTRACT
In this report a 20-year-old male patient who had suffered tonic-clonic seizure after a single induction dose of etomidate until a bispectral index value of 60 is presented. Our best knowledge, this case is the first report of pure etomidate [with induction dose] induced generalized tonic clonic seizure proven with EEG. Anaesthesiologists should be careful against such a complication even in the induction stage of anaesthesia during etomidate use

We present a patient who developed visual loss after carbon monoxide [CO] poisoning and was treated with hyperbaric oxygen. Clinical Presentation and Intervention: A 21-year-old woman poisoned with CO [with coma lasting 4 h and carboxyhemoglobin level 46%] developed seizures and cortical blindness 3 days after poisoning. Four years later, her visual acuity was 0.2 in both eyes. An 18F-fluorodeoxyglucose positron emission tomography [PET] scan showed reduced metabolism in the bilateral posterior temporal and occipital lobes. The patient received a total of 50 hyperbaric oxygen sessions over 3 months for visual loss and the visual acuity improved to 0.5 in both eyes. In addition, increased metabolism was detected in the brain in post-treatment PET scans. PET documented brain hypoperfusion 4 years after CO poisoning and hyperbaric oxygen therapy improved visual acuity. However, we cannot endorse routine use of hyperbaric oxygen for such patients, until results of further clinical trials demonstrate efficacy of hyperbaric oxygen in CO-induced chronic brain injury
