What are the 3 main problems associated with general anesthesia in the horse?

General Anaesthesia Risks
All anaesthesia procedures have the following potential complications: cardiac arrest, tissue damage, bone fractures, iatrogenic injury.

How do you anesthetize a horse?

Induce anesthesia using drugs and techniques that are familiar to you. The intravenous combination of diazepam or mida- zolam and ketamine administered to horses fully sedated with xylazine or detomidine is use- ful.

Which phase of anesthesia is the greatest risk for horses?

The heavy weight of the horse and its poor tolerance to depression of cardiovascular and respiratory functions could explain a higher rate of complications in this species (4). The recovery phase is described as the riskiest phase of equine anesthesia.

When should you Extubate a horse?

Extubation is performed when the horse begins to swallow and attempts to chew. Prolonged anesthesia in dorsal recumbency can lead to congestion of the nasal folds and mucosa of the turbinates.

What is the most serious complication of anesthesia?

Hypotension (Low Blood Pressure)
While most healthy patients tolerate this transient hypotension, there are reports of cardiac arrest occurring following the placement of spinal or epidural anesthetics. Extra care must be taken in patients receiving neuraxial anesthesia that have a cardiac history.

What is the most common cause of anesthetic mishaps?

Three Common Causes of Anesthesia Injuries or Death

• Unavoidable injury. There is inherent risk in medical procedures, especially those that include anesthesia.
• Lack of communication. Anesthesiologists need to have excellent communication with patients, their families, and medical colleagues.
• Negligence.

How do vets sedate a horse?

Xylazine is a common equine sedative. It can be given iv, im or (less commonly) sq and acts on alpha 2 receptors. It also provides analgesia and is synergistic with opioids for both sedation and analgesia. Doses range from 100-200 mg iv (1-2cc of 100mg/ml) for most horses.

What is horse anesthesia called?

Ketamine. Ketamine is a dissociative anesthetic agent used to induce recumbency in horses after sedation. It is commonly combined with diazepam to prolong the anesthetic duration and to enhance relaxation.

What is the number one killer in horses?

The number one killer of horses is colic. Colic is not a disease, but rather a combination of signs that alert us to abdominal pain in the horse. Colic can range from mild to severe, but it should never be ignored. Many of the conditions that cause colic can become life threatening in a relatively short period of time.

Why is sufficient padding required for recumbent horses in the operating room?

Recumbency in equine patients leads to atelectasis and ventilation-perfusion mismatch which ultimately results in hypoxemia. Additionally, horses in recumbency without adequate padding can suffer myopathies or neuropathies making it difficult for them to recover to standing.

How long does it take a horse to recover from anesthesia?

The timing depends on many factors, however, and some horses will “come around” after 30 minutes, while other remain stupefied for an hour and a half. During that time, you’ll want to keep him from eating, moving around or interacting with other horses. A stall is the safest place for a sedated horse to recover.

What is the 20% rule horse?

The 20% Rider Weight Rule
The 20% weight rule (ride and saddle) is a good starting point for considering how much weight a horse can safely carry. Generally, ponies will be able to carry a bit more than 20%. While tall horses will only be comfortable carrying a bit less.

How Long Can horses gallop before they get tired?

In full flight (in a gallop) a horse can cover up to just over 3km before it begin’s feeling fatigued. However if gaits are varied with canters and trotting, a well-conditioned horse can cover 30 to 50km in a day (while giving the horse multiple breaks in between to regain strength).

How long can you haul a horse without stopping?

Horses are fine for up to 9 hours in a trailer as long as they have food and water, and unloading during the trip just adds to your end time considerably. Rather, get to where you are going and let them –and you- have a long rest.

How do they wake you up from anesthesia?

After the procedure
When the surgery is complete, the anesthesiologist reverses the medications to wake you up. You’ll slowly wake either in the operating room or the recovery room. You’ll probably feel groggy and a little confused when you first wake.

Do you pee under general anesthesia?

General anesthesia paralyzes the bladder muscles. This can make it not only hard to pee, but impact your ability to recognize you have to urinate altogether. Additionally, many surgeries involve the placement of a Foley catheter—a tube put in the body to drain urine from the bladder.

What is the risk of not waking up from anesthesia?

First and foremost, both cases are extremely, extremely rare. In fact, the likelihood of someone dying under anesthesia is less than 1 in 100,000. This is the same as 0.0001% of a chance.

How common are anesthesia mistakes?

Anesthesia errors happen every day, sometimes with fatal consequences. If a mistake happens, it is important to determine if the medical care provider can be held accountable for the anesthesia error.

What is the most serious toxic reaction to local anesthetics?

However, with more potent local anesthetics, cardiac toxicity has been found to arise concurrently with seizures or even precede them. Hypotension and bradycardia are often the first signs of cardiac toxicity. However, arrhythmias are responsible for most reported cases, with bradyarrhythmias being the most common.

What happens if an anesthesiologist makes a mistake?

Injuries – even death – can result from too much, too little, or the wrong type of anesthesia. Mistakes made during or after the administration of anesthesia may be grounds for a medical malpractice lawsuit against the anesthesiologist and the hospital or medical facility where the error occurred.
