When Treating Hypotension In The Anesthetized Horse What Drug Is Commonly Used?

Dobutamine—a β1-adrenergic agonist—is the standard “go to” positive inotropic agent for treating equine hypotension. This drug acts on the myocardium to increase the strength of contraction.

How do you treat hypotension in horses?

Dobutamine is the standard positive inotropic agent for treating equine hypotension during anaesthesia. It increases cardiac contractility and therefore stroke volume and cardiac output resulting in an increase in blood pressure. Care must been taken when the patient is severely hypovolaemic.

Which of the following drugs is used to treat hypotension during surgery?

Hypotension during anesthesia and surgery is commonly treated with vasopressors such as phenylephrine (PE), a synthetic pure vasoconstrictor, or norepinephrine (NE), which has both inotropic and vasoconstrictor activity.

Which drug is used as an anesthetic for horses?

1 More than 90% of equine veterinarians use ketamine as the primary anesthetic drug for short-term anesthesia, with many incorporating diazepam to augment mus- cle relaxation.

What actions can you take to address the hypotension seen during anesthesia?

Ephedrine and phenylephrine
Ephedrine is the first-line treatment of intraoperative hypotension during general anesthesia. Ephedrine is an indirect alpha and beta-adrenergic agonist, whereas phenylephrine is a direct alpha-agonist of the sympathetic system. These drugs have been well studied in the obstetrics setting.

What is the first line treatment for hypotension?

Fludrocortisone is recommended as first-line drug therapy. This is a drug that prevents dehydration by causing the kidneys to retain water. This drug boosts the blood volume, which raises the blood pressure.

How is hypotension shock treated?

Initial goal‐directed resuscitation for hypotensive shock usually includes administration of intravenous fluids, followed by initiation of vasopressors. Despite obvious immediate effects of vasopressors on haemodynamics, their effect on patient‐relevant outcomes remains controversial.

What sedative would you use in a hypotensive patient?

I like a dilaudid push of 1mg after hemodynamics have settled out followed by a drip 0.5-2mg/hr. The sedation choice for me is between low dose propofol (10-30 mcg/kg/min) and dexmedetomidine.

What are hypotensive drugs used for?

Hypotensive drugs, particularly nitroglycerine tablets and calcium channel blockers, are often used to relieve angina pectoris. Angina often is the result of partial occlusion of the coronary vessels by fatty deposits (atheroma) or blood clots. Hypotensive drugs reduce arterial blood pressure and cardiac output and…

How is hypotension treated after surgery?

Stand up slowly: Take time to move around and stretch before standing. This will help get blood flowing in your body. Stay away from caffeine and alcohol: Both can cause dehydration. Eat small, frequent meals: Some people experience low blood pressure after eating, and smaller meals help reduce your risk.

What is epinephrine used for in horses?

For emergency use only in treating anaphylactoid shock in sheep, swine, cattle, horses, dogs and cats.

What is the most common drug used in horse racing?

What drugs are likely to be abused—and why? One of the most contentious drugs in horse racing is furosemide, commonly known as Lasix. In humans, it’s used to prevent fluid retention for patients with heart failure, liver disease, or kidney problems.

What is oxytocin used for in horses?

Oxytocin is a small protein hormone that is routinely administered to mares for evacuation of uterine fluid and treatment of retained placenta. It may also be used for induction of labor in late term mares. Mares with a clinically ‘normal’ uterus should not have any significant amount of fluid in their uterus.

What is the solution to hypotension?

Fluids increase blood volume and help prevent dehydration, both of which are important in treating hypotension. Wear compression stockings. Also called support stockings, these elastic stockings are commonly used to relieve the pain and swelling of varicose veins. They improve blood flow from the legs to the heart.

Is atropine used for low BP?

Atropine is the drug of choice for management of patients with SB and hypotension and is effective in the treatment of ventricular arrhythmias as well as conduction disturbances in patients with inferior myocardial infarction.

Which of the following is the best drug for management of hypotension caused by spinal anesthesia?

Ephedrine is also the most appropriate choice for treating the noncardiac sequelae of spinal anesthesia, that is, increased arteriolar dilatation and venous capacitance. Ephedrine is the preferred treatment of hypotension in patients with relatively low heart rate.

Which IV fluid is best for hypotension?

Isotonic crystalloid solutions are typically given for intravascular repletion during shock and hypovolemia. Colloid solutions are generally not used. Patients with dehydration and adequate circulatory volume typically have a free water deficit, and hypotonic solutions (eg, 5% dextrose in water, 0.45% saline) are used.

What is the most popular medication for low blood pressure?

Several drugs are used to treat low blood pressure. The most commonly prescribed of them are fludrocortisone and midodrine. Midodrine works by tightening blood vessels, which increases blood pressure.

What type of drug is used to elevate the blood pressure in shock and hypotension?

Epinephrine (Adrenalin)
Epinephrine is used for hypotension that is refractory to dopamine or norepinephrine. It stimulates alpha- and beta-adrenergic receptors, resulting in relaxation of bronchial smooth muscle, increased cardiac output, and increased blood pressure.

Why is dopamine used to treat hypotension?

Dopamine is traditionally used as the initial agent for treatment of neonatal hypotension because of its inotropic and vasoconstrictive actions. Additional vasopressors and/or hydrocortisone are often administered to increase blood pressure (BP) to the desired range.

How is dopamine used to treat hypotension?

Dopamine is a peripheral vasostimulant used to treat low blood pressure, low heart rate, and cardiac arrest. Low infusion rates (0.5 to 2 micrograms/kg per minute) act on the visceral vasculature to produce vasodilation, including the kidneys, resulting in increased urinary flow.
