| Anesthetics for toy dogs My cousin put all this info together for me. So I only wish I knew this before my Lexie died!! http://www.yorkietalk.com/forums/gen...oflourine.html Isoflurane is the anesthetic of choice. Don't use Halothane or any of the barbituates . Some vets will "mask" a tiny dog with Isoflurane rather than use the injectable and some vets will not intubate at all, but this depends on the type of surgery being performed. This is an excellent method whenever possible. Last but not least, DO NOT ALLOW YOUR VET TO USE ANY KIND OF BARBITUATES TO ANESTHESIZE YOUR TOY DOG. MOST PARTICULARLY NOT PENTABARB. Many toy dogs have died needlessly because of UNINFORMED VETS WHO ARE DECADES BEHIND IN USE OF ANESTHETICS FOR TOY DOGS. If your vet thinks Isoflurane is too expensive and refuses to use it, then FIND ANOTHER VET THAT will use it. It could and probably will save your dog's life. Do not let your vet use this anesthesia. Isoflurane and Sevoflurane are much more expensive for the vet to use, but dogs come out of anesthesia very quickly. If you let your vet use the barbituate anesthesia there is a strong possibility that your dog will not wake up!

| I think that the most important thing is to ask your vet lots of questions first. Make sure they have experience with the smaller dogs. Know ahead of time if you are going to use pain meds, use the IV drip, heated table, Do that pre-op bloodwork. If your dog is smaller try to be the first appointment of the day, they will not have to go as long with out eating as the dogs who are done later.

| I just want to add, masking only, is good when there is high risk. However, there is a very fine line between awake and asleep when done like this, the gas has to be even more carefully monitered than when an injection is used first. Many times when the animal is masked only, they can start to wake and move, even panic while still opened up. When you use the injection to initiate anesthesia and then gas the vet is able to keep them more evenly under anesthesia than with the gas only.

| Do not use halothane and this is what they used on my lexie! Alex's Yorkie Care Frequently Asked Questions. Page 3. My Yorkie needs surgery. What should I know about anesthesia and intubating? There are a couple of different dangers in surgery for toy dogs and they are not insurmountable, but they are VERY SERIOUS. 1) DON'T ever allow the vet technician to intubate your toy dog. Too many small toy breeds have had TRACHEAL INJURY and suffered and DIED because of collapsing tracheas from injury to the trachea during intubation. Make sure that the vet knows that you expect him/her to use the smallest possible tracheal tube to intubate your toy dog. Speak up! It could mean saving the life of your little dog. If the vet treats you like an "overprotective" Mom, find another vet that will understand. 2) Proper use of Ace Promezaine as a pre-anesthetic injection is ok so that the dog can be intubated. 3) Isoflurane is the anesthetic of choice. Don't use Halothane or any of the barbituates (see number 4, below). Some vets will "mask" a tiny dog with Isoflurane rather than use the injectable and some vets will not intubate at all, but this depends on the type of surgery being performed. This is an excellent method whenever possible. 4) Last but not least, DO NOT ALLOW YOUR VET TO USE ANY KIND OF BARBITUATES TO ANESTHESIZE YOUR TOY DOG. MOST PARTICULARLY NOT PENTABARB. Many toy dogs have died needlessly because of UNINFORMED VETS WHO ARE DECADES BEHIND IN USE OF ANESTHETICS FOR TOY DOGS. If your vet thinks Isoflurane is too expensive and refuses to use it, then FIND ANOTHER VET THAT will use it. It could and probably will save your dog's life.

| Halothane and Iso were used on my Lexie This is what they used on my yorkie. Halothane. THE HAEMODYNAMIC EFFECTS OF HALOTHANE IN DOGS http://bja.oxfordjournals.org/cgi/co...tract/45/5/416 Analogue techniques were applied to measurements of phasic aortic blood flow and pressure to obtain continuous recordings of peripheral vascular resistance and circulatory function in open-chest dogs during basal narcosis with chloralose. Whereas the hypotension following hexamethonium 1 and 3 mg/kg i.v. was associated with a marked fall in peripheral vascular resistance and some reduction of maximum acceleration and cardiac output, the hypotension during ventilation with 1 and 2% halothane was associated with a large reduction in maximum acceleration (i.e. cardiac depression) and cardiac output with a relatively small fall in peripheral vascular resistance. In closed-chest dogs 1–2% halothane caused falls in arterial blood pressure and heart rate similar to those after hexamethonium 1–3 mg/kg i.v. without comparable impairment of either vagally-induced bradycardia or the contractions of the nictitating membrane due to sympathetic nerve stimulation. Ganglion blockade did, however, become prominent with concentrations of 4% halothane. It is thought that diminished central vasomotor tone, a reduction of the effects of the sympathetic mediator on blood vessels and a direct relaxant effect of halothane on vascular smooth muscle also contribute importantly to the peripheral vascular depression. SORRY BUT ALL VETS SHOULD KNOW THIS!!! __________________ Quote:

| yes the safest way to do anesthesia is first get blood and urine checked then make sure they use isoflurine as sevo can cause hypothermia in toy breed. Also they need to do iv fluids and catheterization. also they need to have one person monitering the procedure and one doing the procedure this is the safest way - so sorry about your little one - i would not have known this myself as my two were spay and neutered and i had no clue back then. I only learned this as researched it before they had to have dentals and why i go to a board certified specialist for dentals as he does everything i am comfortable with and he actually does the dental himself |

| sevo has no smell and that is what they use for humans and why it is so expensive and iso is a little less expensive but it has an odor to it. I would not mask down as that is very stressful on a dog from what i have learned. If the vet is use to small dogs they have tiny tubes or they use cat tubes as i asked this as well as you want a small tube. Both my malt and yorkie had dentals and never coughed after being under with dentist. |

| don't beat yourself up once you know better you do better and most of us would not have known this either when we first had our dogs and we have learned from others such as yourself sadly - I almost lost my dog at 2 as i did not know about pancreatitis in yorkies so that is why it is so important to help others and learn from each other so this is great that you posted this as it will help others - i use to be much more trusting but have learned sadly the hard way I need to educate myself and why i try to help others and learn for my little ones as well |

| i always cringe when people say they get dentals for $100 etc as if the vet is doing all the proper things that is way too cheap as iso is not cheap and all of the things necessary is not cheap so I think some vets cut corners to lower costs and this is where the problems occur in toy breeds |

| Also, be aware of pre-meds that are administered prior to Iso.
