Veterinary anaesthesia and analgesia
-
To determine the analgesic and systemic effects of epidural administration of ketamine, lidocaine or a combination of ketamine/lidocaine in standing cattle. ⋯ Further research is necessary to determine whether this combination using this technique provides sufficient analgesia for flank surgery in standing cattle.
-
To evaluate the efficacy of ultrasound-guidance in nerve blockade of the sciatic and saphenous nerves in dogs and to determine if this technique could allow lower anaesthetic doses to be used with predictable onset and duration of effect. ⋯ None of the bupivacaine doses was significantly superior, though there was a tendency for a better block with the high bupivacaine dose. Either the technique or the doses used need further modification before this method will be useful in clinical practice.
-
To compare the postoperative analgesic effects of intravenous (IV), intramuscular (IM), subcutaneous (SC) or oral transmucosal (OTM) buprenorphine administered to cats undergoing ovariohysterectomy. ⋯ IV and IM administration of buprenorphine provided better postoperative analgesia than SC or OTM administration of the drug and these routes of administration should be preferred when buprenorphine is administered to cats.
-
To evaluate the cardiopulmonary effects of two different constant rate infusions (CRI) of dexmedetomidine (1 and 1.75 microg kg(-1 )hour(-1)) in experimental ponies. ⋯ Although significant, cardiopulmonary effects of the dexmedetomidine CRIs in isoflurane anaesthetized ponies were small, without differences between the two dose rates.
