Among the 130 Holstein cattle scheduled for flank surgery 90 cattle received a mixed anesthetic consisting of 1 ml of xylazine hydrochloride and 3 ml of lidocaine hydrochloride by modified dorsolumbar epidural anesthesia. Eighteen cattle with dehydration and or lameness received a mixed anesthetic containing ml of xylazine and 3 ml of lidocaine. Infiltration anesthesia was performed in 22 cattle whose epidural space could not be reached in order to perform the flank surgery. The surgeries began about 12 min after the administration of the anesthetic and lasted for about 36 min. The modified method using a fixed volume of anesthetic was successfully introduced and effectively used in a bovine referral center. This modified method will allow veterinarians to save time and effort thus lowering the cost of each surgery. Key words anesthesia cattle dorsolumbar epidural flank surgery Introduction Several methods of anesthesia for flank laparotomy in standing cattle have been described 2 11 These methods include infiltration line block and inverted L-block paravertebral proximal and distal epidural and subarachnoid with or without a catheter anesthesia. Each method has some advantages .
