The erythrocyte sedimentation rate (ESR) is a routine marker of inflammation in human medicine, and it is influenced by erythrocyte features and the level of some plasma proteins. The Westergren method is the reference technique in humans; however, this manual technique has been scarcely used in animals and has not been validated. An automated veterinary in-clinic device (MINI-PET) is able to measure ESR on EDTA-blood tubes. This study aimed to evaluate the comparability of ESR values measured with two tests in cats and dogs admitted to a veterinary clinic and in anemic individuals. Analytical comparability and decision limits were calculated in both species and clinical groups. Comparisons were also made between the two species. The two ESR methods had different decision limits in the investigated population of dogs and cats, and a method-specific interpretation of their results is suggested. Healthy cats had significantly higher values than healthy dogs using both the Westergren and MINI-PET methods. By both methods, anemic individuals had higher ESR values than the matched subgroups with erythrogram values within the reference range, probably due to concurrent inflammation in most anemic animals studied. In general, ESR measures should be evaluated in conjunction with erythrogram values.

Background: Optimizing pain control and anesthesia stability is essential for surgical outcomes in dogs. This study evaluated the effects of preoperative tapentadol on anesthesia depth, recovery, and serotonin levels in dogs undergoing elective spaying. Methods: Sixty-six healthy female dogs were randomly assigned to three groups: standard pain relief, tapentadol alone, or tapentadol combined with standard pain relief. Anesthesia was induced with propofol and maintained with sevoflurane. Intraoperative heart rate, blood pressure, anesthetic depth, postoperative sedation, pain scores, and plasma serotonin concentrations were recorded. Results: Tapentadol-treated dogs showed deeper and more stable anesthesia during surgical stimulation, higher early postoperative sedation that resolved within two hours, and reduced postoperative serotonin levels compared with controls. All analgesic protocols maintained adequate pain control, and biochemical parameters remained within normal limits. Conclusions: Preoperative tapentadol enhances anesthetic stability, supports smoother early recovery, and modulates serotonin levels in dogs, suggesting benefits for perioperative pain management and overall surgical welfare.

Maintaining cardiovascular stability during anesthesia is essential, yet the routine use of atropine to prevent vagally induced low heart rate may impose additional stress on the heart. This randomized, controlled, observer-blinded, clinical study aimed to evaluate whether ondansetron, a selective 5-HT₃ receptor antagonist, could serve as an alternative anesthetic adjuvant to modulate autonomic activity while maintaining cardiovascular stability in dogs. A total of 66 female dogs, with a mean age of 1.5 years and a mean weight of 16–18 kg ASA I, undergoing elective surgery were assigned to three study groups to receive atropine, ondansetron, or no autonomic-modulating drug. Heart rate, arterial pressure, respiratory rate, and NT-proBNP were recorded before, during, and after anesthesia. Dogs treated with ondansetron maintained stable cardiovascular values throughout the procedure, with no episodes of low heart rate or excessive increases in heart rate. In contrast, atropine induced marked and sustained elevation in heart rate and higher arterial pressures. Concentrations of the cardiac biomarker NT-proBNP increased significantly 48 h after surgery in the atropine group but remained unchanged in the ondansetron group, indicating the absence of additional myocardial stress. These findings suggest that ondansetron may help preserve autonomic balance during anesthesia while minimizing myocardial stress. Ondansetron could represent a useful component of multimodal anesthetic protocols, particularly in dogs in which excessive cardiac stimulation should be avoided.

This study aimed to compare the physiological impact of open ovariectomy (the O group) and laparoscopic ovariectomy (the LA group) in dogs by evaluating intraoperative nociceptive responses, postoperative pain, inflammatory markers, and oxidative stress parameters. Sixty healthy dogs were randomly assigned to either technique or a control group (CNT). A standardized anesthetic protocol was used, and their vital signs, pain scores, and blood parameters were measured before, during, and after surgery. Pain was evaluated using the Colorado State University Canine Acute Pain Scale. Oxidative stress was measured by assessing levels of catalase (CAT), superoxide dismutase (SOD), myeloperoxidase (MPO), butyrylcholinesterase (BuChE), and malondialdehyde (MDA). Both techniques were safe and well tolerated, with no complications or need for rescue analgesia. However, the open surgery group exhibited significantly higher levels of inflammatory and oxidative stress markers postoperatively, including increased MPO and MDA levels and decreased BuChE. In contrast, the laparoscopic group showed only mild, transient changes, suggesting reduced tissue trauma. The higher glycemic levels observed in the open surgery group further suggest increased tissue trauma and systemic stress, reinforcing the conclusion that laparoscopy has a lower metabolic impact. Although the laparoscopic procedures require more time, their lower physiological impact may facilitate improved postoperative recovery. These results support laparoscopy as the preferred surgical approach in veterinary practice due to its association with improved metabolic stability and recovery outcomes.

Atlantoaxial subluxation (AAS) is a neurosurgical condition caused by joint hyperflexion and is characterized by the development of compressive cervical myelopathy. Various ventral fixation techniques have been described to permanently reduce the subluxation by long-term stabilization of the atlantoaxial joint. However, the rate of complications related to implant failure with these techniques remains high. The aim of this study was to describe a cervical distraction–stabilization technique using screws and PMMA to treat AAS and evaluate the clinical outcomes based on neurological and radiographic follow-up. Magnetic resonance imaging (MRI) was performed to confirm the diagnosis of AAS and identify any associated intraparenchymal lesions. Computed tomography (CT) scans were performed for surgical planning. No complications resulting in irreversible damage, surgical revision, or euthanasia protocol were observed. In the immediate postoperative period, the neurological scores showed an improvement of approximately two points from the preoperative values in all subjects. At the 6-month neurological examination (medium-term follow-up), 93% (13/14) of the dogs showed normal neurological function with no signs of pain. Based on clinical follow-up data, the cervical distraction–stabilization technique described in this study appears to be a valuable surgical alternative to treat AAS in toy-breed dogs.

Canine disc-associated cervical spondylomyelopathy (DA-CSM) is a form of caudal CSM, characterized by the compression of the spinal cord and nerve roots due to an intervertebral disc protrusion. It is more frequent in large canine breeds. A variety of surgical techniques has been proposed for DA-CSM. The aim of the study was to evaluate the outcomes of a cervical distraction–stabilization technique using an intervertebral anchored fusion device (C-LOX) combined with a locking compression plate (LCP plate) for the treatment of DA-CSM in dogs, based on clinical and radiographical follow-up data. Thirteen dogs affected by DA-CSM were included in the study. After the surgical procedure, an improvement in neurological status was documented in 9/13 cases. This cervical distraction–stabilization technique seems to be a valuable surgical alternative to treat this canine pathology.

The present clinical study was approved by the Review Board for Animals Care of the University of Parma prot N. 03/CESA /2023, which provided a consent to the clinical study: regulation (EU) no. 536/2014. (22A01712) (GU General Series n.65 of 18-03-2022); European Law (O.J. of E.C. L 358/1 12/18/1986), and USA Laws (Animal Welfare Assurance No A5594-01, Department of Health and Human Services, USA). The owners signed a voluntary informed consent form prior to the dogs’ enrollment in the study. Twenty female dogs, aged 1±1.5 months, and weighing 16± 0.5 kg were enrolled in the study. The inclusion criterion of the patients was to undergo ovariectomy surgery; dogs enrolled in this study had normal physiological, haematological and biochemical parameters.

Computed tomography (CT) is an advanced imaging technique that may lead to detect “incidentalomas”, unexpected asymptomatic lesions found during unrelated examinations. Their clinical meaning and management are not clear for veterinarians, who risk unnecessary investigations that harm the patients. This study is a retrospective analysis that aims to investigate incidentalomas in CT exams and to describe their prevalence, location, types and follow-up, their correlations and associations with the species, breed, sex, and age of patients examined and with the kind and number of sites scanned. The reports of 561 CT scans performed in 512 dogs and 49 cats in a veterinary facility over six years were reviewed and compared to the clinical records of the patients. Eighty incidentalomas were found in 57 dogs and four cats. A significant positive correlation was found in dogs between age and the prevalence of incidentalomas. In dogs, the prevalence of incidentalomas was significantly higher in Boxers and in neck, thoracic, and abdominal scans. Spinal incidentalomas were the most common typologies in dogs. This study can represent a tool that allows clinicians to acquire greater awareness about incidentalomas and to carry out the evidence-based clinical management of them.

Background: Umbilical hernia is one of the most common developmental defects in swine, producing large economic losses for farmers, forced to slaughter animals at a younger age and therefore at a lower weight to prevent fatal complications. This study describes a surgical technique to repair umbilical hernia through the use of autologous prostheses, allowing recovery of the affected animals; Methods: After a general examination of the swine and examination of the lesions, the swine were anesthetized and underwent surgery. The surgery was performed by combining the traditional herniorrhaphy with the inclusion and fixation of a peritoneal flap obtained from the incision of the same hernial sac; Results: Follow-ups were carried out at 7, 30 and 60 days and demonstrated healing in all of the treated subjects; Conclusions: The use of this surgical technique allows for providing resistance to herniorrhaphy performed through the use of a cost-free autologous biomaterial prosthesis, with excellent tissue compatibility. This might allow for reducing significantly the rate of relapses and eliminating the risk of rejection.

The purpose of the present study was to test whether the addition of cisatracurium in combination with propofol and sevoflurane would result in a change in doses of used anesthetic drugs. Ten dogs (Group A) undergoing elective unilateral mastectomy surgery were included in the study. To induce and maintain anesthesia, subjects received propofol and sevoflurane at varying doses; analgesia was performed with remifentanil. After three months, the same subjects (Group B) underwent contralateral mastectomy and received the same anesthetic protocol with the addition of cisatracurium at a dosage of 0.2 mg/kg⁻¹. The following parameters were monitored during anesthesia: heart rate, systolic blood pressure, end-tidal CO₂, oxygen saturation, halogenate requirement, and rectal temperature at baseline (T⁰), induction (T¹), 5 (T⁵), 10 (T¹⁰), 15 (T¹⁵), 20 (T²⁰), 25 (T²⁵), 30 (T³⁰), and 35 (T³⁵) time points. In Group A, halogenate requirement was reduced at all the time points other than T1 (p < 0.001); in Group B, the percentage of halogenate requirement was already reduced at T¹ and remained constant during the experimental period, showing no significant intragroup differences. The dose requirements of sevoflurane and propofol varied significantly between the two groups, with significantly lower dosages in the Group B (the cisatracurium-treated group). Moreover, patients treated with cisatracurium showed a stable anesthetic plan. The nondepolarizing-muscle-relaxant cisatracurium besylate could be considered a useful adjunct to anesthetic protocols.
