More than 25,000 chemical items have the aptitude to reason ocular burns. simply because such burns may end up in lack of sight or the necessity for corneal transplantation, they have to be taken very heavily. This ebook is the 1st to be dedicated completely to chemical ocular burns. All points of the topic are lined, together with background, epidemiology, chemical brokers and reactions, histology, pathophysiology, medical symptoms, clinical and surgical remedies, and emergency care. specific realization is paid to the mechanisms curious about ocular burns and to the hyperlinks among the chemical reactivity of corrosive brokers and the scientific manifestations. present rules of decontamination are totally defined and the newest therapy ideas are mentioned intimately. This publication stands on the interface of the chemical and scientific sciences. it is going to be of serious sensible worth to ophthalmologists and medical professionals in emergency scientific and burns devices, and may acquaint chemists with the medical effects of corrosivity.

Sample text

The heating produced during the contact of a concentrated corrosive and water can be experimentally observed in a beaker. The effect can be observed in statics or in dynamics during a simulation of wash. 72). 72 Sulfuric acid experimental washing Evolution of the temperature during the dosage of 1 ml 95% sulfuric acid by Tap water 60 50 T°C Water T (°C) 40 30 20 10 0 0 50 100 150 200 250 300 Time (s) If during a static dilution, the temperature is very high, it is no more the same there during a dynamic wash.

2). The intensity of reaction of the chemical aggressor can be represented on a scale of energy, the functioning of which is governed by a simple rule. 47). The reaction develops until equilibrium reaching a specific pH. Acid1 reacts on base2 when pK1 < pK2. The reaction will move even more to the right side when pK1–pK2 is big. 3 Constituents of the Tissues: Which Are the Biological and Biochemical Targets? 50 Acidic potential of an alcohol Irritant HD Corrosive Irritant 9 Without action 5 Irritant 4 Irritant Corrosive • For chelating agents, we will use the complexation constant.

68). 70). 71). On the contrary, the increasing addition of Hexafluorine® very quickly restores both the pH and the pF toward the physiologically acceptable level. Other types of chemicals, as concentrated corrosives and particularly the acids, may react with water by a release of heat. The heating produced during the contact of a concentrated corrosive and water can be experimentally observed in a beaker. The effect can be observed in statics or in dynamics during a simulation of wash. 72). 72 Sulfuric acid experimental washing Evolution of the temperature during the dosage of 1 ml 95% sulfuric acid by Tap water 60 50 T°C Water T (°C) 40 30 20 10 0 0 50 100 150 200 250 300 Time (s) If during a static dilution, the temperature is very high, it is no more the same there during a dynamic wash.
