Punch resection alaplasty technique in dogs and cats with stenotic nares: 14 cases.
Punch resection alaplasty is a previously unreported surgical technique for the management of stenotic nares. Nine dogs underwent the procedure in conjunction with soft palate resection and/or laryngeal sacculectomy. ⋯ Symmetrical resection was achieved, providing excellent cosmesis. Good to excellent results were achieved in all cases, with owners feeling that their pet's overall well being was improved following surgery.

Ivermectin is a commonly used veterinary drug that may cause serious problems in overdose situations. A retrospective study was completed, which evaluated canine exposures to ivermectin from 1998 to 2005. ⋯ Some dogs may have p-glycoprotein defects or other reasons for increased susceptibility to ivermectin toxicosis. The clinician should be aware that clinical signs may develop even at dosages previously thought to be of little risk (e.g., 0.2 to 2.5 mg/kg in breeds historically considered to have normal p-glycoprotein function).

Effects of carprofen and morphine on the minimum alveolar concentration of isoflurane in dogs.
The minimum alveolar concentration (MAC) of isoflurane in dogs was determined following carprofen (2.2 mg/kg per os) alone, morphine (1 mg/kg intravenously) alone, carprofen and morphine, and no drug control in eight healthy adult dogs. Isoflurane MAC following administration of morphine alone (0.81%+/-0.18%) or carprofen and morphine (0.68%+/-0.31%) was significantly less than the control MAC (1.24%+/-0.15%). ⋯ Results indicated that administration of morphine alone or in combination with carprofen significantly reduced the MAC of isoflurane in dogs. The isoflurane MAC reduction was additive between the effects of carprofen and morphine.

This study evaluated two methods of endotracheal tube selection using 28 fresh canine carcasses of various ages, weights, and genders. The two selection methods were 1) nasal septal width pairing with outer diameter of an endotracheal tube, and 2) digital palpation of the tracheal outer diameter to determine the endotracheal tube size. All dogs were dolichocephalic breeds. ⋯ However, evidence shows that the digital palpation method is slightly more effective than the nasal width method in selecting the best-fitting endotracheal tube. The percentage of the best-fit tube selection for the nasal septal width method was 21%, while the digital palpation method was 46%. With these two methods, selecting an endotracheal tube that is too small is possible, especially when the tube internal diameter is > or =7 mm.

Randomized Controlled TrialIncisional block with bupivacaine for analgesia after celiotomy in dogs.
A blind, placebo-controlled clinical trial was performed to evaluate the postoperative analgesic effect of preoperative infiltration of the incision site with bupivacaine in dogs undergoing celiotomy. Sixty dogs were randomly allocated into four groups: preoperative bupivacaine, postoperative bupivacaine, preoperative saline, and postoperative saline. All dogs were premedicated with acepromazine and meperidine; then they were anesthetized with thiopentone and isoflurane. ⋯ After surgery, pain scores were assigned using a numerical rating scale. Preoperative bupivacaine was associated with significantly lower pain scores and a significantly lower need for opioid administration. The authors conclude that a preoperative incisional block with bupivacaine seems to be a useful adjunct for controlling pain after celiotomy in dogs.
