RESUMO A população de cães e gatos errantes é um problema ABSTRACT Stray dogs and cats is a serious problem to public health and animal welfare. Prepubertal gonadectomy from six weeks of age is a solution to effective pet overpopulation control.The benefits and adverse effects of this procedure are discussed in this paper, allowing the veterinarians to obtain knowledge and scientific basis to critical analysis to the topic, practice spread and owner awareness.
In order to use and study minimally invasive techniques to reduce side effects of ovarian-hysterectomy (OHE) in bitches, the aim of this study was to compare time, surgical complications, pain and postoperative inflammatory response, caused by single port videolaparoscopic OHE and traditional miniceliotomy with snook hook. Twenty-four healthy bitches were randomly divided in two groups: videolaparoscopy (Video) and miniceliotomy (MiniLap). Surgical time and complications, pain, need for analgesic rescue, C-reactive protein concentration, glycaemia and voluntary food ingestion were evaluated during 24 hours following the procedure and compared statistically. Surgical time (38±7min), surgical complications (17%), postoperative pain intensity, need for analgesic rescue and C-reactive protein concentration were similar between groups (P>0.05). Glycaemia was lower in Video group (P=0.03), animals fed faster and in greater proportion (P=0.02). Thus, it is concluded that both OHE techniques result in similar complications, surgical time and inflammatory response; however, animals on Video group fed more readily and presented lower glycaemia, which point to lower stress levels. These findings validated the indication of this technique.

Analgesia preventiva con tramadol o metadona para mastectomia y ovario histerectomía en perrasAnalgesia preventiva com tramadol ou metadona para mastectomia e ováriohisterectomia em cadelas Abstract Background: mastectomy and ovariohysterectomy (OVH) in bitches are critical surgeries and pain control can be challenging. Objective: to evaluate the efficacy of pre-emptive analgesia with methadone (MET) or tramadol (TRA) in postoperative pain intensity, cardiorespiratory effects, and anaesthetic/analgesic consumption in female dogs undergoing mastectomy and OVH. Methods: a prospective randomized blind clinical trial was used to evaluate 48 bitches of various breeds, aged 10 ± 3.7 years, weighing 16 ± 12 Kg, and with multiple mammary tumours. The animals were distributed in two groups: TRA group received 5 mg/Kg tramadol and MET group 0.5 mg/Kg methadone intramuscularly, 10 min prior to anaesthesia induction with propofol followed by maintenance with isoflurane. Heart (HR) and respiratory (RR) rates, mean arterial pressure (MAP), propofol induction dose (PID), oxyhemoglobin saturation (SpO 2 ), end-tidal isoflurane concentration (EtISO), and carbon dioxide pressure (EtCO 2 ) were measured during the intra-operative period. Post-operative pain was evaluated for 12 h and rated according to the Melbourne scale. Rescue analgesia (0.5 mg/Kg methadone, 2 mg/Kg lidocaine, or 0.01 mg/Kg/min ketamine IV) was given when necessary and post-operative analgesic consumption recorded. Statistical tests were used to compare treatments. Results: rescue analgesia requirements, pain score, PID and analgesic consumption were significantly lower (p<0.05) in MET group. The HR was higher in TRA group, while EtCO 2 and MAP were higher in MET group (p<0.05). Conclusion: methadone was more effective than tramadol in pre-emptive analgesia but not completely adequate on controlling pain in bitches subjected to
SILSTM via an umbilical hernia opening was used in the correction of an abdominal cryptorchidism in a dog. The SILSTMport was inserted through a 2.5 cm skin incision on the umbilical hernia and pneumoperitoneum was established with CO2. A 10mm telescope, 5mm laparoscopic Babcock clamp, and a clamp with combined cutting and coagulation features were used for the dissection and removal of the testicle through the SILSTM port. The treatment proved to be effective, easy, and quick to perform. However, the lack of triangulation between clamps and telescope limited the movement of the instruments, making it more laborious than a multiple-trocar approach. It can be concluded that the use of a SILSTM port through a pre-existing opening of the abdominal wall enables a reduction of the risks associated with multiple incisions; such as injury and manipulation of internal organs, pain, bleeding, and development of new hernias.
