Rehydration of diseased animals (commonly known as hanging saline) is a common method of treating diseases in livestock. When using, determine the amount of rehydration according to the degree of dehydration of diseased animals, and use drugs according to the nature of dehydration. Blind rehydration can have adverse consequences. First, determine the amount of fluid in accordance with the degree of dehydration 1. Mild dehydration: Loss of water accounted for about 4% of body weight, clinical symptoms are not obvious, only mental depression, dry mouth, desire to drink, reduced urine output, skin elasticity and other symptoms. Moderate dehydration: Loss of water is about 6% of body weight, sick animals dry mouth, obvious desire to drink water, sunken eye sockets, reduced skin elasticity, blood viscosity, oliguria or anuria, circulatory disorders, fatigue and weakness. Severe dehydration: Loss of water accounts for about 8% of body weight, sick body temperature, eye socket deep depression, corneal dry dull, mental depression or coma lying, thick blood, circulation height obstacles. 2. To determine the amount of fluid commonly used method: the body weight multiplied by the percentage of dehydration and then divided by 2, that is, the actual fluid intake. If the weight of 300 kilograms of cattle in moderate dehydration fluid volume: 3006% 2 = 9 (kilograms), that is 9000 ml, 1 day in two lost, then according to the condition decide whether additional fluid volume. Second, according to the nature of dehydration rational drug use 1. Water dehydration (hyperosmotic dehydration) mainly due to dehydration: When the drinking water is insufficient or difficult to swallow, the carcass still loses water from breathing, perspiration, urination, and faeces due to a decrease in the amount of intake, resulting in dehydration. More dehydration with less loss of sodium and less loss of water. Mainly to pay water, lose 5% glucose, or 5% glucose 2 plus normal saline 1 is appropriate. 2. Loss of salt-based dehydration (hypotonic dehydration): In the heat stroke, acute fatigue, or body sweating in the campaign, a large number of loss of body fluids, such as drinking only a large amount of water, without salt, will cause Loss of salt, loss of water, low permeability of dehydration. Rehydration to enter normal saline, or saline and 5% glucose is appropriate. 3. Mixed dehydration (Isospermic dehydration): When diarrhea, abdominal pain, and insufficient drinking water after sweating, the amount of water and sodium lost is approximately equal to isotonic dehydration. The rehydration solution is suitable for inputting compound sodium chloride solution or 5% glucose physiological saline, and it can also be transfused with a solution of normal saline and 5% glucose equal parts. The commonly used rehydration preparations include 5% isotonic glucose, normal saline, sugar saline, compound sodium chloride solution, 5% sodium bicarbonate solution, and mixed solutions. Rehydration methods include oral, enema and injection. For those who have a desire to drink, try to solve the problem of dehydration through drinking water, and pay attention to adding proper electrolytes in drinking water. If necessary, medications can be administered through the stomach tube or refilled with enema. The use of intravenous rehydration should pay attention to: Where added calcium, potassium, magnesium preparations, the infusion rate should be slow to prevent the sudden stop of heartbeat; liquid temperature should not exceed 40 °C; pay attention to observe the diseased animals with or without infusion Reactions, such as found disturbed, restless, rapid heartbeat and breathing, muscle tremors or sweating, should immediately stop the infusion, and the injection of epinephrine hydrochloride, diphenhydramine hydrochloride and other rescue.
