= "3492nsf3"> Cardiovascular emergencies have the characteristics of urgency, complicated condition, and critical danger. It is important to be skilled in the use of cardiovascular first aid drugs in clinical practice.adrenaline, , and norepinephrine are 3 commonly used first aid drugs.Woolen cloth?The small medicine in the world will summarize the following:
adrenaline [1]
adrenaline has a stronger excitable effect on the beta receptor on coronary vascular and skeletal muscle vascular, manifested as vascular dilation.Because of the excitement of the heart, the blood vessels of the skin, mucous membranes, and internal organs (such as the kidneys) are contracted; it can increase the systolic blood pressure and have no significant impact on diastolic pressure.Table 1 The usage of adrenaline
Alien CAdrenaline [2]
isop propypeninine can be used for cardiac shock, infectious shock and bronchial asthma acute attack;Tachyfilers at the end of the ventricular.Severe , sinus house blocking, sinus stop, and complete room conduction block can also be used.
Table 2 Table 2 The Dosage of Actinine in isopropypes
[3]
Reymarking tidaline can cause extreme contraction of vascular blood vessels, which causes blood pressure to cause coronary arteries.Blood flow increases; the excitement of adrenaline alpha receptor is strong.In addition, it also has an exciting effect on the beta receptor, which can enhance myocardial contraction function and increase the amount of blood emoticons. Varic veins can be used for shock caused by various reasons. Pay attention to external leakage prone to local tissue necrosis.
Usage and dosage: When doses of small doses of 0.4 μg/kg per minuteExcitement α receptor is the main.After the administrate vein is administered quickly, the effect is fast after taking the administration, and the efficiency of the drug is maintained for 1-2min after stopping the injection.
By the patients weight (KG) by the total norepinein dose of 0.03 or 0.3, the dosage of the adrenaline of the adrenaline of 0.03 or 0.3 is matched with 50ml liquid.0.01 μg/kg/min or 0.1 μg/kg/min [1].
What is the difference between the three?
These three medicines belong to the adrenaline receptor excitement drug, which can excite the heart, cannot be taken orally, and can cause fast tolerance.They are combined with adrenaline receptors to produce adrenaline -like effects by excitement receptor.
adrenaline is an α, β receptor agonist, which acts on the myocardial, conducting system and sinus node β1 and β2 receptors.medicine.Opopropine has almost no effect on the α receptor, mainly exciting β receptors, and low selectivity for β1 and β2.
The norepinephrine is an alpha receptor excitement drug, which has a weak effect on the heart beta1 receptor, and has almost no effect on the beta2 receptor. It is often used as a heximal drug application.
The big department of the department every week is the most tense moment of the border medicine. This is not just asked by the director:
