Anestesia epidural para realização de osteossíntese de fêmur e correção de luxação coxofemoral em tamanduá bandeira (Myrmecophaga tridactyla) : relato de caso

Abstract

Polytraumas in wild animals due to automobile accidents are increasingly frequent. Based on this, this study aimed to report the use of epidural anesthesia in a giant anteaters (Myrmecophaga tridactyla) for correction of femoral fracture and right hip dislocation for trans-operative analgesia. A female anteater, weighing 28.3kg and about two years old, with femur fracture and right hip dislocation due to a car accident was admitted to the Veterinary Hospital of the University Federal of Mato Grosso. The animal was submitted to anesthetic-surgical procedure to correct the lesions, for this we used as pre-anesthetic medication an association of ketamine (8mg/kg) and midazolam (0.2mg/kg), and analgesic support with tramadol (10mg/kg) and meloxicam (0.2 57 mg/kg). Right after, followed with anesthetic induction and maintenance through the supply of isoflurane, administered through a face mask. Loco-regional, epidural block was used with an association of lidocaine (4mg/kg) and morphine (0.1 mg/kg). During the entire anesthetic procedure, stability of cardiovascular and respiratory variables was observed, in addition to satisfactory anesthetic recovery at the end of the procedure. We concluded that the use of epidural anesthetic technique is safe and provides analgesia in 8 the trans-operative period in giant anteaters for fracture fixation and correction of right hip dislocation.
