Evaluation of a laparoscopically assisted ovariectomy technique in cats.

OBJECTIVE: To describe a laparoscopically assisted ovariectomy (LAO) technique in the cat with a bipolar vessel sealing device (BVSD) or suture ligation and to compare the outcomes to open ovariohysterectomy (OO). STUDY DESIGN: Randomized prospective study ANIMALS: Healthy, adult, sexually intact female cats (n = 30). METHODS: Ten cats were assigned to each group: LAO with BVSD (group A), LAO with ligation (group B), and OO with ligation (group C). Surgical times and complications were assessed. Serum glucose and cortisol were measured prior to surgery and at 1, 2, 4, 6, 12, and 24 hours after surgery. Pain was scored by using an interactive visual analog scale (IVAS) at 0, 1, 2, 4, 6, 8, 12, 18, 24, 36, and 48 hours after surgery. Rescue analgesia was provided when IVAS score was 4 or more. Physiological and serum values and IVAS scores were compared among groups with area under the curve (AUC) by using a 1-way ANOVA. RESULTS: Surgical time was shortest for group C (19.1 ± 5.2 minutes; P < .0002); there was no significant difference between groups A (27.7 ± 6.6 minutes) and B (33.2 ± 8.2 minutes). All procedures were completed successfully. No significant differences among groups were found in IVAS scores (P = .36), rescue analgesia (P = .22), glucose AUC (P = .53), or cortisol AUC (P = .27). CONCLUSION: The LAO technique was accomplished as described in all cats with no complications or failures. Pain scores were not different from cats undergoing OO. LAO can be performed efficiently to maximize the benefits of minimally invasive surgery and is amenable to clinical practice.

Use of skin stretching techniques before bilateral caudal superficial epigastric axial flaps in a dog with severe burns.

This report describes how 2 days of skin stretching facilitated a tension-free closure of single event bilateral caudal superficial epigastric flaps in a dog with severe hindquarter burns. Full healing at all surgical sites with only minor dehiscence and without further treatment or abnormalities of gait or coat regrowth was achieved.

Usage des techniques d'étirement de la peau avant des lambeaux de peau axiaux épigastriques caudaux bilatéraux chez un chien atteint de graves brûlures. Ce rapport décrit comment deux jours d'étirement de peau ont facilité la fermeture sans tension d'un événement unique de lambeaux épigastriques superficiels caudaux bilatéraux chez un chien souffrant de graves brûlures à la cuisse. Une guérison complète a été obtenue à tous les sites chirurgicaux, avec seulement une déhiscence mineure, sans aucun autre traitement ni anomalie de la démarche ou de la repousse de la fourrure.(Traduit par Isabelle Vallières).

Quantification and characterization of pleural fluid in healthy dogs with thoracostomy tubes.

OBJECTIVE To quantify and characterize pleural fluid collected from healthy dogs after placement of a thoracostomy tube (TT). ANIMALS 8 healthy Coonhound-cross dogs (mean ± SD weight, 27.2 ± 1.6 kg). PROCEDURES Thoracic CT of each dog was performed before placement of a TT and daily thereafter for 7 days. Thoracic fluid volume was calculated from CT images. Effusion was aspirated when detected; volume was recorded, and cytologic analysis and bacterial culture were performed. RESULTS Mean ± SD volume of pleural effusion detected by CT was 1.43 ± 0.59 mL/kg (range, 0.12 to 3.32 mL/kg). Mean volume collected via aspiration was 0.48 ± 0.84 mL/kg (range, 0 to 2.16 mL/kg). Cytologic analysis yielded results consistent with an exudate, characterized by septic suppurative inflammation in 6 dogs and mixed inflammation in 1 dog; there was insufficient volume for analysis in 1 dog. Sufficient volume was obtained for bacterial culture for 6 dogs, which yielded pure growths of Staphylococcus pseudintermedius (n = 3) and Streptococcus equi subspecies zooepidemicus (2) and mixed growth of both of these species (1). The TT was removed before day 7 in 4 dogs because of pyothorax (n = 3) and irreversible damage to the TT (1). CONCLUSIONS AND CLINICAL RELEVANCE Presence of a TT induced a minimal volume of pleural effusion in healthy dogs. Pyothorax developed in most dogs between 4 and 6 days after TT placement. On the basis of these findings, a TT should be removed by the fourth day after placement, unless complications are detected sooner.
