Efeitos cardiovasculares e analgésicos da administração epidural de ropivacaína isolada ou associada à morfina, em felinos

Abstract

RESUMO Visando avaliar os efeitos cardiovasculares e analgésicos de dois protocolos epidurais em felinos submetidos à OSH, 16 gatas mestiças, adultas, que, após indução à anestesia geral, receberam anestesia epidural (L7 -S1) com 0,26mL kg -1 de ropivacaína 0,75%, isolada (GR) ou associada a 0,1mg kg -1 morfi na (GRM).

Effects of epidural anesthesia with tramadol, ropivacaine or tramadol-ropivacaine combination, in bitches undergoing ovariohysterectomy under anesthesia with isoflurane

“…Vettorato et al (2010) used tramadol at a dose of 2 mg·kg -1 , administered IV, and achieved satisfactory analgesia for 8 h in dogs undergoing orthopedic surgery (evaluated by the Glasgow scale). The differences in the duration of analgesia observed by different researchers can be attributed to the use of different scales for evaluation and surgical stimulus rather than the doses and routes (POHL et al, 2011;TEIXEIRA et al, 2013;REGALIN et al, 2014). Table 3.…”

“…Ropivacaine (0.3 ml·kg -1 , DI) combined with butorphanol (0.1 mg·kg -1 , DI) produced analgesia for an intermediate duration (308 min) in dogs subjected to OSH (ALBUQUERQUE et al, 2010). Analgesia was maintained for longer durations when combined at a higher dose (0.26 mL·kg -1 , ED) with morphine (0.1 mg·kg -1 , ED) in cats subjected to the same surgical procedure (evaluated using multidimensional scaling) (REGALIN et al, 2014). Table 4.…”

“…ED anesthesia is a safe and easy technique that provides adequate analgesia for retroumbilical surgical procedures. The duration of analgesia varies depending on the drug and the volume used (TONNER, 2005;REGALIN et al, 2014). This technique should be employed more frequently in veterinary medicine, particularly in patients with a higher risk under general anesthesia, since it reduces the doses of such drugs.…”

“…The combination of drugs for ED anesthesia tends to result in the potentiation of anesthetic and analgesic effects, reduction in the side effects from the isolated use of drugs, as well as a reduction in the required dose and toxicity (VALADÃO et al, 2002;CASSU et al, 2008;SILVA et al, 2008;ALBUQUERQE et al, 2010;REGALIN et al, 2014). Ropivacaine when combined with an opioid analgesic is efficient, but when administered alone is not able to provide adequate analgesia during an orthopedic surgical procedure (ADAMI et al, 2012).…”

“…Ropivacaine when combined with an opioid analgesic is efficient, but when administered alone is not able to provide adequate analgesia during an orthopedic surgical procedure (ADAMI et al, 2012). A small volume (0.2 ml·kg -1 ) does not provide the suitable blocking time required for conducting OSH and therefore requires intraoperative analgesic rescue (ALBUQUERQUE et al, 2010;REGALIN et al, 2014).…”
