In vitro evaluation of the effect of hypothermia on coagulation in dogs via thromboelastography.

Objective: To evaluate the effect of temperature alterations on in vitro coagulation in healthy dogs using thromboelastography (TEG).

Design: In vitro study.

Setting: University teaching hospital.

Imaging diagnosis--acquired pectus excavatum secondary to laryngeal paralysis in a dog.

A 13-year-old neutered female Labrador retriever had inspiratory dyspnea secondary to bilateral laryngeal paralysis. Radiographically, there was pectus excavatum with a mediastinal shift to the right. Arytenoid lateralization was performed, relieving the upper respiratory obstruction, and the sternal deformity also resolved.

Evaluation of dexmedetomidine and ketamine in combination with various opioids as injectable anesthetic combinations for castration in cats.

Objective: To compare the efficacy and cardiorespiratory effects of dexmedetomidine-ketamine in combination with butorphanol, hydromorphone, or buprenorphine with or without reversal by atipamezole in cats undergoing castration.

Design: Prospective, randomized, split-plot, blinded study.

Animals: 30 healthy male cats.

Evaluation of dexmedetomidine and ketamine in combination with opioids as injectable anesthesia for castration in dogs.

Objective: To compare efficacy and cardiorespiratory effects of dexmedetomidine and ketamine in combination with butorphanol, hydromorphone, or buprenorphine (with or without reversal by atipamezole) in dogs undergoing castration.

Design: Prospective, randomized, split-plot, blinded study.

Animals: 30 healthy client-owned sexually intact male dogs.

Effects of anesthetic protocol on normal canine brain uptake of 18F-FDG assessed by PET/CT.

The purpose of this study was to assess the effects of four anesthetic protocols on normal canine brain uptake of 2-deoxy-2-[18F]fluoro-D-glucose (FDG) using positron emission tomography/computed tomography (PET/CT). Five clinically normal beagle dogs were anesthetized with (1) propofol/isoflurane, (2) medetomidine/pentobarbital, (3) xylazine/ketamine, and (4) medetomidine/tiletamine-zolazepam in a randomized cross-over design. The standard uptake value (SUV) of FDG was obtained in the frontal, parietal, temporal and occipital lobes, cerebellum, brainstem and whole brain, and compared within and between anesthetic protocols using the Friedman test with significance set at P < 0.

Gallbladder agenesis in a Maltese dog.

This report describes the diagnostic evaluation of a 7-month-old, female Maltese dog with elevated liver enzymes. Marked elevations of alanine transferase were the significant clinical findings. A diagnosis of gallbladder agenesis was made, based on lack of a gallbladder on ultrasonography and on surgical exploration.

Buried tension sutures: force-tension comparisons of pulley, double butterfly, mattress, and simple interrupted suture patterns.

Objectives: To compare suture patterns (simple interrupted, modified pulley, horizontal mattress, double butterfly) by use of a novel in vitro model that quantifies force required for closure against tension.

Study Design: In vitro study.

Sample Population: Suture constructs.

Laparoscopic ovariohysterectomy in nine dogs.

Minimally invasive surgery has been found in humans to reduce pain, incidence of infections, and duration of hospitalization. Minimally invasive procedures are also being described in veterinary medicine. Laparoscopic ovariohysterectomy (OHE) was performed on nine, healthy, intact female dogs using a Harmonic scalpel.

Microvascular free tissue transfer of the rectus abdominis muscle in dogs.

Objective: To assess donor-site morbidity and survival of the rectus abdominis muscle with an overlying skin graft after free tissue transfer to a medial femorotibial defect in dogs.

Study Design: Experimental study.

Sample Population: Phase 1: 6 canine cadavers; phase 2: 7 adult mixed-breed dogs.
