“…To minimize recovery complications from anesthesia, 1) proper positioning and providing adequate padding of the patient intra-operatively, 2) maintaining MBP above 70 mmHg during anesthesia, 3) providing adequate analgesia for safe recovery, 4) ensuring patency of airway after extubation, and 5) insufflating O 2 at a flow rate of 15 L/min are generally recommended in routine clinics (4). Improved recovery from anesthesia is associated with shorter, less invasive surgical procedures and slower recovery (18).…”

:This study was conducted to analyze the results of inhalation anesthesia performed at the equine hospital of Korea Racing Authority (KRA) and to find out the influencing factors on mortality during and/or after inhalation anesthesia. Among 585 cases of anesthesia, orthopedic surgery (410) was performed the most frequently, followed by colic surgery (85) and upper airway surgery (45). Twenty out of 585 horses were either euthanized or died during and/or after anesthesia. Among those twenty horses, fourteen horses received colic surgery, three received orthopedic surgery, and three others received upper airway surgery. The major causes of mortality were rupture of intestine in colic surgery and airway obstruction during recovery in upper airway surgery. Myopathy, refracture, laminitis were the causes of mortality in orthopedic surgery. Consequently, the horses that received colic and upper airway surgeries showed significantly high mortality rate rather than horses that received orthopedic surgery (p < 0.01). According to the results, horses that received colic surgery showed the highest mortality rate from euthanasia due to poor and grave prognosis. To reduce the perioperative mortality of horses, it is recommended to perform perioperative intensive care for colic surgery and careful monitoring for upper airway surgery during recovery.

Summary A 17‐month‐old Warmblood filly was referred to our clinic for evaluation of congenital facial nerve (FN) paralysis. Clinical examination revealed a right‐sided facial paralysis with mild masticatory muscle atrophy, mild dysphagia and exposure keratitis. Apart from the FN deficits, neurological examination of the remaining cranial nerves showed no abnormalities. Magnetic resonance imaging (MRI) examination using a 3.0 Tesla scanner showed that in comparison to the left FN, the intracranial section of the right FN between the pons and internal acoustic canal was thinner, whereas it appeared indistinct and thickened within the internal acoustic canal and facial canal. Signs of meningitis or encephalitis were not present on MRI. Cerebrospinal fluid analysis showed mild pleocytosis. The owner of the filly requested euthanasia due to the guarded prognosis. At necropsy, the intracranial section of the right FN was macroscopically thinner than the left side and within the facial canal, a 5 mm tissue stump could be identified with an absent extracranial part of the right FN. Histological examination of the brain stem showed different architecture of the left and right motor nuclei of the FN: in the left nucleus, motor neurons of a normal size and well stainable Nissl bodies were present, whereas in the right nucleus, neurons with Nissl bodies were decreased in number and size. Further, a cytoplasmic rich cell population with a nucleus size compatible with normal neurons was present. These cells were suspected to be atrophic neurons. The tissue stump within the facial canal was histologically identified as connective tissue. Unilateral malformation of the FN has not previously been described in the horse. This filly showed a right‐sided, intracranial hypoplasia accompanied by an extracranial aplasia of the FN causing complete, congenital facial nerve paralysis, which corresponded to a difference in the architecture of the affected motor nucleus of the FN.
