Abstract

Simple Summary: Orchiectomy is a common surgical procedure performed on small animals and postoperative analgesia is very important because pain causes various negative effects that prevent patient recovery. Our study aimed to compare the intraoperative ultrasound-guided funicular block with ropivacaine and general anaesthesia using hypnotic and/or analgesic drugs and the postoperative hemodynamic stability and pain scores. This study demonstrated that the use of ultrasound-guided funicular, using ropivacaine, guarantees long-lasting and high-quality analgesic coverage and minimises the post-surgical pain inevitably associated with orchiectomy. This study stemmed from a general trend towards increasing attention on postoperative pain after orchiectomy in dog. Since veterinarians are becoming more focused on relieving surgical pain, anaesthetists are expected to use better protocols that can minimise pain. In fact, acute postsurgical pain is of great interest due to potential risk of becoming chronic if not treated properly. The routine use of the intraoperative ultrasound-guided funicular block with ropivacaine block is considered a useful alternative for pain management for orchiectomy in dogs, which can be performed under sedation or superficial general anaesthesia. In addition, the intraoperative ultrasound-guided funicular block with ropivacaine block ensures satisfactory analgesic coverage that lasts for at least 6 h postoperatively. Orchiectomy is a common surgical procedure performed on small animals, and it requires postoperative pain management despite its relative simplicity. This study aimed to evaluate the hemodynamic stability, intraoperative administration of additional hypnotic and/or analgesic drugs, and postoperative pain scores following the combination of ultrasound-guided injection of ropivacaine hydrochloride into the spermatic cord and infiltration by the same anaesthetic of the incisional prescrotal line (ROP) or general anaesthesia. Dogs in the ROP group showed greater intraoperative hemodynamic stability and lower pain scores than the control group. The locoregional approach used in this study proved effective in minimising the responses to the surgical stimulus and ensured adequate analgesia intra- and postoperatively. This method, called ultrasound-guided funicular block, allows orchiectomy to be performed under deep sedation without general anaesthesia. [ABSTRACT FROM AUTHOR]

Abstract

Prostasome-like vesicles (PV) are components of the canine prostatic fluid during ejaculation and despite some enzymatic activities have been identified recently, their functions in the reproductive events in this species are still poorly understood. In this study, we evaluated at neutral or slightly alkaline pH, the effects of different concentrations of purified PV on sperm cell motility characteristics and the impact on the short- and long-term preservation of preserved semen maintained at room temperature. Two different experiments were performed. In the first experiment, purified PV were added at increasing concentration (1.25, 2.5, 5, 10, and 20 μL equivalent to 1, 2, 4, 8, and 16 μg of protein, respectively) to aliquots of 100 μL of preserved semen maintained at 22 °C at the following time points: 0, 30, 60, 120, 240, and 480 min. Computer-assisted sperm motility characteristics and pH were assessed three times at each time points, for each sample and for every concentrations. In the second experiment, the purified PV were added with the same methods as described above but only at time 0. Sperm motility characteristics and pH were assessed over the time. This study showed how the addition of purified PV to preserved semen affects negatively (p < 0.05) at neutral and alkaline pH, both total and progressive motility in a concentration depending manner. Furthermore, prostasome addition was demonstrated to change the quality of sperm movement which may represent a mechanism facilitating sperm cells attachment to the uterine epithelium and facilitating energy preservation before fertilization.

Abstract

The work was carried out on a total of 26 male dogs that on the basis of clinical examination, prostate ultrasound and prostate biopsy, were divided prospectively into four groups: (1) normal dogs (control group; n ¼ 8); (2) dogs with benign prostatic hyperplasia (group BPH; n ¼ 8); (3) dogs suffering from prostatitis (group prostatitis; n ¼ 4); (4) dogs with prostatic tumors (group tumors; n ¼ 6). The examination of the prostate bymeans of contrast medium and dedicated ultrasound system allowed a detailed qualitative and quantitative analysis of prostatic vessels in normal and diseased conditions, enabling the detection and characterization of different disease states, and quantification of parameters such as peak intensity of perfusion (%), arrival time of the contrast medium to its maximum value of video intensity (time to peak [TTP; seconds]), regional blood volume, regional blood flow, and mean transit time (MTT [seconds]). The hemodynamic indices TTP (P < 0.01) and MTT (P < 0.001) of diseased prostate groups were significantly lower than those in the normal prostate group although there were no differences among diseases. Optimal cutoff values were 31 seconds (Sensitivity: 72%; Specificity: 88%) and 47 seconds (Sensitivity: 100%; Specificity: 88%) while area under receiver operating characteristic curveswere 0.86 (P< 0.01) and 0.97 (P
