A “Light Meal” Three Hours Preoperatively Decreases the Incidence of Gastro-Esophageal Reflux in Dogs (Original Study)

AbstractEmerging evidence from veterinary and medical clinical research shows that reducing preoperative fasting time may reduce the incidence of gastro-esophageal reflux (GER) intraoperatively. In order to evaluate the effect of two different preoperative fasting times on the incidence of GER during general anesthesia, 120 dogs were randomly assigned to two groups: administration of canned food 3 h before premedication (group C3, n = 60) and administration of canned food 10 h before...

Postoperative Analgesia Provided by Liposomal Hydromorphone in Client-Owned Dogs Undergoing Limb Amputation (Original Study)

AbstractThe analgesic efficacy of liposomal hydromorphone (LE-hydro) was tested in dogs undergoing limb amputation. The positive controls (n = 10) received subcutaneous (SQ) hydromorphone (0.2 mg/kg) and 1.5 mL of blank liposomes before surgery; fentanyl continuous rate infusion (CRI), 5–10 μg/kg/hr IV, during and for 24 hr after surgery; and a fentanyl patch at extubation. The negative controls (n = 7) received SQ hydromorphone (0.2 mg/kg) and 1.5 mLs of blank liposomes SQ before surgery,...

Comparison of Morphine, Morphine-Lidocaine, and Morphine-Lidocaine-Ketamine Infusions in Dogs Using an Incision-Induced Pain Model (Original Study)

AbstractWe aimed to compare antinociceptive effects of IV infusions of morphine (M), morphine-lidocaine (ML), or morphine-lidocaine-ketamine (MLK) combined, in a mild-to-moderate pain model in dogs. Eighteen adult hounds were heavily sedated with IV morphine (0.2 mg/kg) and dexmedetomidine to undergo thoracic skin incisions. After reversal, dogs were randomly assigned to receive loading doses of lidocaine and ketamine (MLK), lidocaine and saline (ML), or equivalent volume of saline (M),...
