Valutazione comparativa degli effetti clinici ed analgesici dell’infusione endovenosa costante di Fentanyl o Lidocaina, in cani anestetizzati con Isoflurano e sottoposti a chirurgia spinale

Anaesthesia for spinal surgery must take into account lesion position, surgical procedure, preoperative anti-inflammatory therapy, existing and postoperative pain. Aim of the present study is to compare the clinical and analgesic effects of either Fentanyl or Lidocaine administered by CRI in two groups of six dogs undergoing spinal surgery under inhalation anaesthesia. Dogs were randomly assigned to one of two analgesic protocols consisting of a loading dose and a CRI either of Fentanyl or of Lidocaine HCl administered just before surgery and throughout the procedure. Vital signs monitoring and postoperative pain score confirmed an anaesthetic sparing effect on ET isoflurane % of both protocols and failed to reveal significant differences among the two groups of dogs
