Retrospective study of the prevalence of postanesthetic hypothermia in cats
A retrospective study of 275 anaesthetic records of cats was undertaken to examine the prevalence of postanaesthetic hypothermia, its clinical predictors and consequences. Temperature was recorded throughout anaesthesia. The temperature reached at the end was classified as hyperthermia (>39.50 °C), normothermia (38.50 to 39.50 °C), slight hypothermia (38.49 to 36.50 °C), moderate hypothermia (36.49 to 34.00 °C) or severe hypothermia (<34.00 °C). Statistical analysis consisted of multiple regression to identify the factors that affect the temperature at the end of the procedure. Before premedication, the mean (sd) temperature was 38.2 (1.0) °C. At 60, 120 and 180 minutes from induction, the temperature was 35.4 (1.4) °C, 35.0 (1.5) °C and 34.6 (1.5) °C, respectively. The prevalence of hypothermia was slight 26.5 per cent (95 per cent CI 21.7 to 32.0 per cent), moderate 60.4 per cent (95 per cent CI 54.5 to 66.0 per cent) and severe 10.5 per cent (95 per cent CI 7.4 to 14.7 per cent). The variables associated with a decrease in the temperature recorded at the end of anaesthesia were the duration of anaesthesia, the reason for anaesthesia (abdominal and orthopaedic surgeries significantly reduced the temperature when compared with minor procedures) and the anaesthetic risk (high-risk cats showed lower temperatures than low-risk cats). The temperature before premedication was associated with an increase in the final temperature.Ciencias Experimentale
Use of a Customized Device for Correction of Antebrachial Angular Deformity in a Dog
Angular deformity is a common condition in dogs that can cause serious malformations and is a challenge for surgeons to correct. A 15-month-
old male Saint Bernard was evaluated due toright foreleg lameness. Orthopedic examination revealed a valgus deformity with external rotation and
anteversion of the forelimb. Carpal examination revealedthe decreased range of motion with slight disturbances in carpal flexion. Radiography of
both forelimbs showed angular deviation because of possible premature physeal closure of the distal ulnar growth plate.Surgical intervention was
selected to correct the angular deformity. A closed-wedge osteotomy was planned using 3D reconstruction, obtained via computed tomography
(CT). In order to accomplish this, a custom-made device was developed to aid the surgeon in establishing the position and orientation of the cutting
planes during the intervention.Long-term follow-up obtained 3 years after surgery revealed the correct ossification of the osteotomy and complete
resolution of lameness. The main advantages of using a customized device obtained from 3D CT include the predictability and accuracy of the method.
The device allows for correction of atriple-axis angular long bone deviation, with full opposition between the bone fragments after osteotomy and
minor loss of length of the limb.Ciencias Experimentale
Proximal Abduction Ulnar Osteotomy (PAUL): Short- and Long-Term Evaluation in Dogs Presenting Medial Compartment Disease
Developmental elbow disease is one of the main causes of lameness in the canine
species and occurs often in large and giant breed dogs. The most frequent manifestation of this
pathology is known as medial compartment disease due to a physiological overload in the medial
region of the elbow. It is considered as a complex disease and the treatment is focused on relieving
the pain and slowing the progression of osteoarthritis. The Proximal Abduction Ulnar Osteotomy
(PAUL) technique is one of the newest techniques whose purpose is the transmission of loads from
the medial to the lateral compartment. In this prospective case series, the authors use the combination
of elbow arthroscopy and the PAUL technique and report a significant improvement in clinical signs,
showing a low major complications rate with a high degree of owner satisfaction.Ciencias Experimentale
Retrospective study of the prevalence of postanesthtic hypotermia in dogs
The anaesthetic records of 1525 dogs were examined to determine the prevalence of
postanaesthetic hypothermia, its clinical predictors and consequences. Temperature was
recorded throughout the anaesthesia. At the end of the procedure, details coded in were:
hyperthermia (>39.50°C), normothermia (38.50°C–39.50°C), slight (38.49°C–36.50°C),
moderate (36.49°C–34.00°C) and severe hypothermia (<34.00°C). Statistical analysis
consisted of multiple regression to identify the factors that are associated with the
temperature at the end of the procedure. Before premedication, the temperature was
38.7±0.6°C (mean±sd). At 60, 120 and 180 minutes from induction, the temperature was
36.7±1.3°C, 36.1±1.4°C and 35.8±1.5°C, respectively. The prevalence of hypothermia
was: slight, 51.5 per cent (95 per cent CI 49.0 to 54.0 per cent); moderate, 29.3 per cent
(27.1–31.7 per cent) and severe: 2.8% (2.0–3.7%). The variables that associated with a
decrease in the temperature recorded at the end of the anaesthesia were: duration of the
preanesthetic time, duration of the anaesthesia, physical condition (ASA III and ASA IV dogs
showed lower temperatures than ASA I dogs), the reason for anaesthesia (anaesthesia
for diagnostic procedures or thoracic surgery reduce the temperature when compared
with minor procedures), and the recumbency during the procedure (sternal and dorsal
recumbencies showed lower temperatures than lateral recumbency). The temperature before
premedication and the body surface (BS) were associated with a higher temperature at the
end of the anaesthesia, and would be considered as protective factors.Ciencias Experimentale
Estudio experimental comparativo de la analgesia intraoperatoria con remifentanilo en el perro
En este artĂculo se comparan las propiedades analgĂ©sicas del remifentanilo y el fentanilo y se estudian la estabilidad cardiovascular, respiratoria y calidad d ela recuperciĂłn en perros anestesiados 11 Beagle con medetomidina, propofol, isoflurano y atracurio. Los analgĂ©sicos empleados fueron fentanilo, remifentanilo y un placebo. Los resultados muestran menores necesidades de anestĂ©sico con ambos opiodes, mejor estabilidad cardiovascular y menores tiempos de recuperaciĂłn con remifentanilo. Ambos fármacos proporcionan buena calidad analgĂ©sica y recuperaciĂłn.Veterinari
