Manual of equine anesthesia and analgesia 2nd edition Pdf Book Description:

The second edition of the Manual of Equine Anesthesia & Analgesia has been updated and rearranged. Most topics have been expanded and new chapters added. Chapters devoted to the sedation and anesthesia of horses undergoing imaging procedures, anesthesia of donkeys and mules, and recognition of pain in horses and donkeys are now included. Case examples of the pharmacologic control of pain are provided, and information on non-pharmacologic treatment of acute and chronic pain using acupuncture and physical rehabilitation techniques have also been added. In addition, a suggested reading list is included for the reader who wishes to seek further information on the topic. This edition of the Manual of Equine Anesthesia & Analgesia strives to deliver relevant information on the physiologic and pharmacologic principles underpinning the anesthesia of equids, in addition to providing useful information on the clinical practice of anesthesia. The Manual has retained the same easily accessible format of the first edition, and we believe that it will be a useful guide to all those involved in the anesthesia of equids.The risk increases with age, and horses aged 12 years or older are at an increased risk of mortality. Older horses may be more prone to fracture of a long bone in the recovery period, which could result in euthanasia. Foals have an increased risk of fatality and this is probably associated with unfamiliarity with neonatal anesthesia, an immature cardiovascular system, and presence of systemic illness.

Pregnant mares have increased risk of mortality in the last trimester of pregnancy and this is probably associated with a need for emergency surgery. Otherwise, there is no difference between sexes. Horses with a high ASA physical status have increased risk of mortality.In otherwise healthy horses, the risk of mortality (euthanasia) following fracture repair is highest from repair failure or from fracture of another bone. However, long periods of anesthesia typical of fracture repair have also been associated with increased mortality, and horses presented for fracture repair may be dehydrated and stressed. Emergency surgery (non-colic) carries a 4.25 times higher risk of mortality compared with elective surgery, and for emergency abdominal surgery the risk of fatality is 11.7%. Colic surgery is associated with increased mortality because of a higher ASA physical status, emergency procedure with less time for stabilization, and use of dorsal recumbency possibly with episodes of hypotension. Eye surgery, in one institution, resulted in longer recovery times and risk of complications and were associated with long anesthesia time compared to non-ophthalmic procedures. Fluconazole (microsomal P450 enzyme inhibitor) use was associated with increased risk of postoperative colic and longer recovery time. The use of the lowest effective volume of local anesthetic for a retrobulbar block was also recommended (10ml/500kg horse). Ophthalmic procedures have been associated with unsatisfactory recovery quality. Assisted recovery with ropes can decrease the risk of fracture and dislocation, although the benefit of assisted-recovery is still debatable. Performing anesthesia outside of normal working hours carries an increased risk for horses. This increase in risk is separate from the fact that most of these cases are emergency in nature. Surgeries performed between midnight and 6a.m. carry the highest risk of mortality. This may be due to the nature of the emergency, as well as to staff shortages and personnel fatigue
