Characteristics and differences of inhalation anesthesia and injection anesthesia

来源:本站 作者:玉研仪器,生物学霸 Time: 2018-11-12 Source: Site Author: Jade research instruments, biology Pa

Animals who often do animal experiments will inevitably need to anesthetize small animals. If they want to be safe during the operation, do not suddenly wake up or die, and do not affect the relevant indicators of the experiment. How should this anesthetic method be chosen? With so many types of anaesthetics, what is the difference? What properties should an ideal anesthetic have?


In fact, anesthesia can be divided into injection anesthesia and inhalation anesthesia according to the type of drug. The ideal anesthetic should be easy to handle, provide fast and adequate anesthesia maintenance, have no side effects, be reversible, and harmless to animals and operators. However, there is currently no anesthetic that can meet the different experimental needs of different laboratories.


今天就来说一说麻醉的那些事儿。 However, in order to facilitate understanding and review, we have combed through the common anesthesia methods, the characteristics and application scenarios of related anesthetics, and today we will talk about those anesthesia.

Commonly used injectable anesthetics



Avertine, pentobarbital sodium and When ketamine is used as an injection anesthetic in animals, it is often used in combination with levulinazine, xylazine, diazepam, and some sedative drugs.

Commonly used inhaled anesthetics


也小于恩氟烷及氟烷 ,通过降低周围血管阻力而使血压下降,但不改变冠脉血流,心律稳定;对肝肾功能几乎没有影响;它还能产生足够的肌肉松弛,可增强去极化肌松药的作用。 The inhibition of the central nervous system by isoflurane inhalation anesthesia is related to the dosage and does not cause increased intracranial pressure; the inhibition of the myocardium is also less than that of enflurane and halothane , which reduces blood pressure by reducing peripheral vascular resistance, but not Change coronary blood flow, stable heart rhythm; almost no effect on liver and kidney function; it can also produce enough muscle relaxation, which can enhance the effect of depolarizing muscle relaxant.


Isoflurane inhalation anesthesia is widely used in animal anesthesia experiments. Isoflurane vaporizers on the anesthesia machine can be used to adjust the volatile concentration of isoflurane to induce general anesthesia and maintain general anesthesia. More than 80% of inhalation anesthesia machine equipment in scientific research laboratories at home and abroad use isoflurane anesthesia.


需要选择气体麻醉机、手术保温系统You can choose gas anesthesia machine and surgical insulation system according to your needs.

Small animal gas anesthesia machine


Animal insulation system


对手术中的动物和术后恢复的动物进行保温,并可进行动物体温测量。 The animal body temperature maintaining instrument (electric heating type) keeps warming the animals during and after the operation, and can also measure the body temperature of the animals.
