Answer:
a) Moist gangrene
Explanation:
Gangrene is the death of body tissue due to insufficient blood supply in a particular region or bacterial infection. The disease is most common in the extremities of the body, including feet, toes, arms and legs, but can also occur in muscles and internal organs.
There are two types of gagrena, dry and moist. Moist gangrene refers to gangrene tissue where there is bacterial infection. Swelling, sores with no demarcation line, unpleasant odor, blisters and "wet" appearance are common in cases of wet gangrene. It usually develops after severe burns, frostbite, or injury. It also often occurs when people with diabetes have foot or toe sores. Moist gangrene should be treated immediately as it spreads quickly and can be fatal.
The symptoms presented by the patient, exposed in the question, show that they are experiencing a case of moist gangrene.
Local anesthetics inhibit nerve conduction in a reversible manner without altering the nerve. The inhibition appears rapidly and for a longer or shorter duration depending on the products and the concentrations used. The extent of the territory rendered insensitive to pain depends on the modes of administration of the local anesthetic, either at the level of the nerve endings, or at the level of a nervous trunk, for example.
They act at the level of the neuronal membrane by interfering with the process of excitation and conduction. The anesthetic crosses the axon membrane, rich in lipids, in the form of base before taking up a cationic form on the internal face of the neuron where the pH is more acidic.
At this level, there is a blockage of nerve conduction by decreasing the membrane permeability to sodium ions that occurs during the depolarization phase. As the progression of the anesthetic action along the nerve increases, the threshold of excitability increases and the conduction time increases. This is completely blocked from a certain concentration of local anesthetic.
The nerve fibers are unequally sensitive to the action of local anesthetics: they disappear in order: the painful, thermal, tactile sensations.
