Product Details

Anesthesia of experimental animals is a complex and systematic task. Correct anesthesia treatment is a powerful guarantee for the success of animal experiments. Improper anesthesia treatment can lead to errors in the experimental results that are difficult to analyze.Small animal anesthesia machineTo achieve good anesthesia results, in addition to mastering the basic knowledge and techniques of animal anesthesia and following scientific anesthesia procedures, it is also necessary to understand various factors that affect animal anesthesia, such as animal factors, environmental factors, etc.

1. Age and weight

The response of animals to * * varies with age. Someone divided rats and mice into three groups based on age: juvenile, adult, and elderly, and observed the effect of age on acute toxicity of ethanol, pentane, and dichloroethane. According to the LD50 and anesthesia concentration observation, the sensitivity shows as juvenile>adult>elderly. The age difference in response to toxic substances may be related to the activity of toxic enzymes. Juvenile animals are sensitive to toxins due to the lack of these enzymes. Newborn rats do not reach the enzyme levels of adult rats until about 8 weeks after birth. The glucuronide converting enzyme in rats reaches the level of adult rats around 30 days after birth. In addition, young animals, especially newborn animals, have underdeveloped liver and kidney function and low elimination ability, which increases the amount of free drugs and drugs entering tissues, making them prone to accumulation poisoning.

Animals with smaller body weight have a higher basal metabolic rate per unit body weight compared to animals with larger body weight. Therefore, the smaller the animal, the higher the dose required per unit body weight. For some chronic experiments with longer observation time, young and smaller weight animals can be selected for the experiment.

2. Gender

Experimental results have shown that animals of different genders have different sensitivities and responses to various stimuli. Female animals have significant changes in their responsiveness during different stages of their sexual cycle, as well as during pregnancy and lactation. Therefore, male animals or an equal number of males and females are generally preferred for experiments. The basal metabolic rate of male animals is higher than that of females, and the metabolic rate of females increases during pregnancy, making them more sensitive to * *. If administered to male rats aged 5-6 weeks, a analgesic effect can be observed, but if given to female rats, there is no analgesic effect. Three month old Wistar rats consume and excrete more ethanol per unit body weight, with females consuming more ethanol than males.

The small animal respiratory anesthesia machine adopts a new main structure, which is more compact in size and saves experimental table space. The gas path conversion of the face mask and induction box is easy to switch with one click operation
