IVPure-transvaginal natural orifice transluminal endoscopic surgery (NOTES) ovariohysterectomy in bitches: a preliminary feasibility study

PURPOSE:To describe video-assisted ovariohysterectomy (OHE) with two portals access in adult intact queens. METHODS:Fifty-two females cats were used. A 4 mm cannula was positioned in the abdomen through an incision close to the umbilicus (first portal), and a pneumoperitoneum was established. A second portal was positioned in the midline of the pre-pubic region. Females were positioned in right lateral recumbency to locate the left ovarian pedicle, and the uterine horn was held by a transcutaneous suture.The pedicle was cauterized and incised. The procedure was then performed on the contralateral ovary. The ovaries were exteriorized from the abdomen, along with the uterus, through the second access point. The uterine body was exposed, fixed and sectioned, and the abdominal incisions were sutured. RESULTS:Surgeries were performed in an average of 41.4±14.2 minutes. The main complications included hypotension (7.7%) and subcutaneous emphysema (7.7%), and 13.5% of the surgeries were converted to laparotomy. CONCLUSION:Ovariohysterectomy using a video-assisted technique and two access portals is safe, has minimal risks and is effective for the spaying of queens.

Constant rate infusion (CRI) shows several advantages in balanced anesthesia, such as reduction of requirement for inhaled anesthetics and control of pain. The most commonly used drugs in these protocols are local anesthetics, dissociative, and opioids, which may be administered alone or in combinations. We evaluated the records of 200 dogs that underwent various surgical procedures with anesthetic or analgesic CRI in the perioperative period during 2011 and 2012 at the Veterinary Hospital of Franca University (Unifran), and identified possible complications during the transoperative period. Records evaluated included clinical state, laboratory tests, drugs used in premedication and induction, and CRI protocol. Acepromazine and morphine were the main drugs used in premedication. Propofol was used to induce anesthesia alone or in combination with other agents. We evaluated records of the 25 different CRI protocols. Fentanyl was the main drug employed in CRI, either alone or in combination. There were 128 episodes of anesthetic complications during CRI;the most common were hypotension, hypertension, and tachycardia, which occurred in 43 (32%), 35 (26.3%), and 19 (14.2%) dogs, respectively. Cardiac arrhythmia was reported in only 4 dogs. Signs of respiratory depression were present in dogs treated with 6 different CRI protocols. The consumption of isoflurane (vol %) reduced between 15.7% and 21.05% after 30minutes of the CRI in the fentanyl and fentanyl-lidocaine-ketamine CRI groups (p<0.05). In conclusion, CRI is a valid component of balanced anesthesia in dogs, safe, and has a low incidence of adverse effects. However, future studies are warranted to describe the results of the clinical use of CRI to better characterize and refine this technique.

Os fármacos mais comumente utilizados nestes protocolos são os anestésicos locais, dissociativos e opioides, que podem ser administrados isoladamente ou em associações. Foram avaliados os prontuários de 200 cães que foram submetidos a diversos procedimentos cirúrgicos com IC de anestésicos ou analgésicos no período perioperatório durante 2011 e 2012 no Hospital Veterinário da Universidade de Franca (Unifran). Foram identificadas possíveis complicações durante o período trans-operatório. Os registros avaliados incluíram estado clínico, exames laboratoriais, fármacos utilizados na pré-medicação e indução, e protocolos de IC. Acepromazina e morfina foram os principais fármacos usados na pré-medicação. O propofol foi utilizado para induzir a anestesia, isolado ou em associação com outros agentes. Foram avaliados os registros de 25 protocolos diferentes de IC. O fentanil foi o principal fármaco utilizado na IC, isoladamente ou em associação. Houve 128 episódios de complicações anestésicas durante a IC; os mais ...
