Irrigation Solution

Hydrogen peroxide, an over the counter irrigation solution used in infected and dirty wounds, has been reported mainly in the anesthesia literature to have life threatening complications. We report a case of near fatal gas embolism during an orthopedic procedure of irrigating the wound of a 30 year old female with chronic osteomyelitis of the femur using hydrogen peroxide solution.

Venous Gas Embolism

Gas embolism to the portal venous system is a well-recognized radiographic sign in infants with necrotizing enterocolitis. It also has been seen after colonic irrigation with hydrogen peroxide solution.1,2 We present what we believe is the first reported patient with radiographic evidence of portal venous gas embolism after ingestion of hydrogen peroxide solution. This finding is important because gas embolism to the portal venous system after colonic irrigation with hydrogen peroxide has been associated with gangrenous and perforated bowel.1,2 CASE REPORT A 2-year-old boy ingested an unknown amount of 3% hydrogen peroxide solution. The child was found with foam around his mouth.

The mechanism of the enzymatic iodination process of diethylmaleate and diethylfumarate (which present no miscibility with water) in the presence of lactoperoxidase, both in diluted hydrogen peroxide solution and in a generating system of hydrogen peroxide using ammonium and calcium iodides as halide sources in disperse system (after an ultrasonic pretreatment) was studied. The obtained sole product (diethyl-2, 3-diiodosuccinate) after the enzymatic iodination process was directly hydrolyzed to a tartaric acid present in an optically inactive form. The mechanism of obtaining the intermediate and final products and respectively, the existence of both D, L-tartaric acid and meso-tartaric acids (as lithium bitartrates) were also investigated.

Therapeutic Value

A 52-year-old male accidentally ingested approximately 100 mL of 35% hydrogen peroxide (H2O2), resulting in the sudden onset of gastrointestinal and neurologic symptoms. Non-contrast abdominal CT revealed extensive portal venous gas and gastric pneumatosis. The patient was treated with hyperbaric oxygen therapy which resulted in complete resolution of symptoms. The case highlights the therapeutic value of hyperbaric oxygen therapy in the treatment of vascular gas embolism and mitigation of concentrated H2O2 ingestion toxicity.

Abstract The usage of the low-cost catalysts for methylene blue removal from wastewater was investigated. Heterogeneous Fenton-like process consists of the use of a hydrogen peroxide solution, and an iron-rich catalyst, red mud and black nickel mud were used for that purpose. The factors such as the catalyst dose and the hydrogen peroxide solution volume were monitored. The results of experiments showed that the degradation of methylene blue dye in Fenton-like oxidation process using selected catalysts can be described by a pseudo-second-order kinetic model. The highest dye removal efficiency (87.15 %) was achieved using the black nickel mud catalyst after 30 minutes of reaction.

Possible Cause

Toxic epidermal necrolysis (TEN) is a rare life-threatening drug-induced mucocutaneous skin disease with a mortality rate of approximately 30%. Nimesulide is a preferential cyclo-oxygenase (COX-2) inhibitor which is frequently used for its antipyretic, anti-inflammatory and analgesic activity. Here, we report a case of nimesulide induced toxic epidermal necrolysis in a 57 years old male patient. This patient was admitted in the hospital with symptoms of epidermal sloughing and fluid filled blisters all over the body following over the counter intake of nimesulide for fever. The drug was promptly stopped, and patient was managed with steroids, antibiotics and other adequate supportive measures. The patient showed significant recovery following stoppage of drug and adequate management. This case highlights the importance of nimesulide and other NSAIDs as possible cause of TEN.
