Abstract(s)
A ovariohisterectomia (OVH) é a cirurgia abdominal mais realizada em medicina veterinária. A
ovariohisterectomia e ovariectomia laparoscópicas bem como a ovariohisterectomia laparoscópica assistida
já foram descritas em pacientes veterinários.
Este trabalho teve por objetivo desenvolver competências na área de cirurgia laparoscópica.
Tentamos comparar os prós e contras das técnicas cirúrgicas em ovariohisterectomia de cadelas, pelo
método convencional e pela cirurgia mínimamente invasiva- laparoscopia e laparoscopia assistida. Para tal
foram definidos 3 grupos de cadelas, cada um com 6 animais, nos quais foram realizadas técnicas cirúrgicas
diferentes: no primeiro foi realizada a ovariohisterectomia “aberta”, no segundo, ovariohisterectomia
laparoscópica e no terceiro ovariohisterectomia laparoscópica assistida. Em todos os procedimentos foram
registados os dados dos animais, como peso, idade e raça e foram critérios incluidos apenas animais
saudáveis. A sedação, pré-anestesia e anestesia utilizada foi igual em todos os grupos. Foram registados
tempo de cirurgia, que se define como o intervalo de tempo desde a entrada à saída do animal na sala de
cirurgia e grau de hemorragia na cirurgia. Os scores de comportamento associados à dor foram registados na
escala de dor de Glasgow e na escala de dor de Melbourne, às 2h antes da cirurgia e às 0, 1, 2, 4, 8,12 e
24h depois da cirurgia. No pós-cirúrgico imediato foi avaliada a recuperação quanto à dor, utilizando escalas
de dor de Glasgow e Melbourne. Foi também registado qualquer complicação neste período. Foram
avaliadas as zonas de sutura às 48h, 72h e 8 dias após cirurgia.
The ovariohysterectomy (OVH) is the most commonly performed abdominal surgery in veterinary medicine. The laparoscopic ovariohysterectomy and ovariectomy as well as the laparoscopic-assisted ovariohysterectomy have been described in veterinary patients. This project aimed to develop skills in the field of laparoscopic surgery. We try to compare the pros and cons of surgical techniques in ovariohysterectomy of bitches, by conventional method (laparotomy) and minimally invasive surgery by laparoscopy and laparoscopic-assisted techniques. Three groups of bitches was defined, each with 6 animals, on each group different surgical techniques were performed: the first group underwent ovariohysterectomy, while in the second group we performed assisted laparoscopic ovariohysterectomy and in the third group laparoscopic ovariohysterectomy. In all procedures pertinent data of animals was recorded, such as weight, age and breed. The study only included healthy animals. Sedation, anesthesia and pre-anesthesia used was the same in all groups. We recorded surgical time, which is defined as the time from entrance until the exit of the animal in the operating room and degree of bleeding during surgery. The scores associated with pain behavior were recorded on the Glasgow pain scale and the Melbourne pain scale at 2 hours prior to surgery and at 0, 1, 2, 4, 8,12 and 24 hours after surgery. Immediately after surgery we assessed the patient for pain recovery, using pain scales of Glasgow and Melbourne. Any complications were also registered during this period. The suture was evaluated at 48 hours, 72 hours and 8 days after surgery.
