A one-year study in a teaching hospital shows that dogs and cats typically experience a 1 in 9 chance of anesthetic complications, with a 1 in 233 risk of death. [12] A larger-scale study states the risk of death in healthy dogs and cats as 1 in 1849 and 1 in 895 respectively. For sick dogs and cats, it was 1 in 75 and 1 in 71 respectively.
MAC is used to compare the strengths, or potency, of anaesthetic vapours. [1] The concept of MAC was first introduced in 1965. [2] MAC actually is a median value, not a minimum as term implies. The original paper proposed MAC as the minimal alveolar concentration, [3] which was shortly thereafter revised to minimum alveolar concentration. [4]
More current studies, however, have failed to show a positive association between use of acepromazine and seizure activity [9]: 116 [16] and show a possible role for acepromazine in seizure control: in a retrospective study at University of Tennessee, acepromazine was administered for tranquilization to 36 dogs with a prior history of seizures ...
The ACVAA serves as the only recognized organization in North America granting board certification in veterinary anesthesia and analgesia. Members of the ACVAA are sought for their expert opinion on matters related to veterinary anesthesia and analgesia. They may be employed in private or academic veterinary hospitals, research institutions, or ...
[3] [4] If an anesthetic has a high coefficient, then a large amount of it will have to be taken up in the body's blood before being passed on to the fatty (lipid) tissues of the brain where it can exert its effect. The potency of an anesthetic is associated with its lipid solubility, which is measured by its oil/gas partition coefficient. [5]
The surgery may be performed via the animal's mouth, with a portion of the vocal folds removed using a biopsy punch, cautery tool, scissor, or laser. The procedure may also be performed via an incision in the throat and through the larynx, which is a more invasive technique. [1] All devocalization procedures require general anesthesia. [2]
In anesthesia, the Mallampati score or Mallampati classification, named after the Indian anaesthesiologist Seshagiri Mallampati, is used to predict the ease of endotracheal intubation. [1] The test comprises a visual assessment of the distance from the tongue base to the roof of the mouth, and therefore the amount of space in which there is to ...
The Meyer-Overton correlation for anaesthetics. A nonspecific mechanism of general anaesthetic action was first proposed by Emil Harless and Ernst von Bibra in 1847. [9] They suggested that general anaesthetics may act by dissolving in the fatty fraction of brain cells and removing fatty constituents from them, thus changing activity of brain cells and inducing anaesthesia.
