“…Regional analgesic methods are a very attractive form of perioperative analgesia, as many of the side effects of systemic opioid analgesics can be avoided or decreased (Carpenter et al., 2004 ; Wolfe et al., 2006 ; Abelson et al., 2009 ; Lemke & Dawson, 2000 ). Opioids have traditionally been the analgesic class used most commonly for orthopaedic surgery but are known to cause undesirable postoperative side effects such as dysphoria (Becker et al., 2013 ; Kongara, 2018 ), gastrointestinal dysfunction such as ileus (Brock et al., 2012 ; Johnson, 1981 ), disruption of temperature regulation (Adler et al., 1988 ) and even adverse immunomodulatory effects (Odunayo et al., 2010 ). Consequently, efficacious and safe alternatives for postoperative analgesia are continuously sought in veterinary medicine.…”
