Immediate first aid: Remove patient from contact with the material. Available from, as of October 4, 2011: http://www.inchem.org/pages/sids.html, Wijburg FA et al; Ann Otol Rhinol Laryngol 94 (4 Part 1): 337-41; 1985. https://www.ncbi.nlm.nih.gov/pubmed/4026118, The protective effect of erythropoietin on the acute phase of corrosive esophageal burns in a rat model. This example confirms that sodium hydroxide is not expected to be systemically available in the body under normal handling and use conditions. Fatal ingestion and fatal dermal exposure has been reported for humans. Following ingestion of a small amount the injury is usually limited to the oropharyngeal region and the esophagus. Get medical attention as soon as possible. Lower pH means a higher concentration of H, The formula for calculating pH is pH = -log. Six animals from Group sodium hydroxide and six from Group erythropoietin-treated were killed at 4, 24, 48, and 72 hours after application of sodium hydroxide to the esophagus. An X-ray showed perforation of the stricture. Skin Contact: CORROSIVE. Sodium hydroxide can pass freely through the cornea and cause damage to all layers of the cornea and to the anterior segment structures in severe cases 20). Thirty-two patients with deep circular burns had nasogastric tubes inserted immediately. They are rapidly transformed due to an uptake of carbon dioxide from the atmosphere resulting in the formation of sodium bicarbonate and sodium carbonate. The area of the right cheek had a bronze discoloration. The greater the volume the greater the risk of duodenal and gastric damage. Pain and irritation are evident within 3 minutes, but contact with dilute solutions may not cause symptoms for several hours. Since neither the presence nor the severity of esophageal burns is predictable, an endoscopy should be performed in all suspected cases. The role of injury to blood vessels remains unclear, as with other chemical burns to the eye the blood vessels of the conjunctiva and episclera are seen to be thrombosed immediately after exposure. A chemical reaction is initiated that produces nitrogen gas from the sodium azide. Although main quantities are used by the industry (large enterprises) it is also widely used by small and medium sized enterprises. The patient died on the operating table. Manitoba OELs (Reg. It is generally used as a solid or a 50% solution. He drank some milk and water and vomited. If sodium hydroxide contacts the skin, immediately flush the skin with large amounts of water. It fails to coagulate protein which would serve to prevent further penetration. Comparison of titratable acid/alkaline reserve and pH in potentially caustic household products. (1989), Wiener Klin Wschr, 101, 318-322, Casasnovas et al. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Eye contact. Part 1: The Chemistry Behind Soap Making, Clean Beauty Is Wrong and Won’t Give Us Safer Products, Should you avoid aluminium in deodorants? Knopp 16) reported that in patients with oral burns approximately one third had significant esophageal injury, whereas 2-15% of patients with esophageal injury had no oral burns. Methylprednisolone was given by retrobulbar and subconjunctival injection. A 20 year old patient presented 2 hours after accidentally spraying herself in the face with an oven cleaner containing 4% sodium hydroxide 45). Sodium hydroxide is approved as a food additive (E 524) 1) for use as an acidity regulator without limitation (quantum satis) in jams, jellies, marmalades, sweetened chestnut purée, other similar fruit and vegetable spreads, processed cereal-based foods and baby foods, other foods for young children, dietary foods for infants for special medical purposes and special formulas for infants. CAS #: 1310-73-2. Mutagenic for mammalian somatic cells. Depending on the concentration, solutions of sodium hydroxide are non-irritating, irritating or corrosive and they cause direct local effects on the skin, eyes and gastrointestinal tracts. In 17 cases the accident happened during work, while 6 cases occurred at home using sodium hydroxide/potassium hydroxide as drain cleaner. When the protective sheath around collagen is damaged, collagenases produced by polymorphonuclear leucocytes infiltrate the damaged area and degrade the corneal collagen causing melting or ulceration of the stroma, formation of descemoteceles (herniation of Descemet’s membrane) and perforation of the cornea.
