Abstract

The spinal surgeries are increasingly common in routine veterinary hospitals, requiring knowledge of different anesthetic possibilities for such procedures, in order to prevent morbidity and mortality in the peri-and post-surgery. Advanced age, prolonged immobility, multiple co-morbidities, as well as the risk of worsening neurological require that the anesthesiologist has special attention in the pre-operative, anesthetic induction and recovery phases. The aim of this study was to analyze the anesthetic records of 48 dogs operated between May 2011 and 2013, the Veterinary Hospital of the Federal University of Santa Maria, performing a retrospective analysis of anesthetic protocols used in patients undergoing spine surgery, noting the results obtained with its use, the occurrence of complications, as well as its relationship to the time of anesthesia. Through data analysis, it was observed that the main drugs used were morphine and midazolam premedication, propofol for induction and isoflurane for maintenance of anesthesia. This protocol maintained the anesthesia required for surgery and caused no complications during the anesthetic and postoperative in 81% of animals. The main complications in this study were in patients undergoing technique "slot" cervical, such as hypotension, which affected 18% of patients and death occurred in 10% of cases.
