Special Issue Information

Dear Colleagues,

Veterinary anaesthesiology is one of the most recognized and in-demand specialties of the veterinary profession. It touches on both the provision of anaesthesia and analgesia in medical and surgical procedures, as well as the recognition and management of pain, including chronic and neuropathic pain.

In parallel with the clinical development of the specialty, in recent years, there has been a notable increase in the scientific information available in the field of small-animal anaesthesia and analgesia. Particularly noteworthy are topics such as the description of new locoregional anaesthesia techniques, as well as the evaluation of their effectiveness in clinical contexts, which have undergone numerous developments. In recent years, special attention has been paid to the development of monitoring and life support techniques, the species and type of pain, as well as specific tools used for pain assessment. Finally, other highly important trending topics are environmental sustainability, climate change, and the well-being of the veterinary anaesthesia team.

This Special Issue on “Research on Small Animal Anaesthesia and Analgesia” addresses the need to continue increasing scientific knowledge in the numerous expanding areas of the specialty. It is expected that this Special Issue will help strengthen the exchange of relevant and innovative research for the veterinary anaesthesia community.

Dr. Susana Canfrán

This study aimed to describe an ultrasound-guided technique for implanting catheters for local anesthetic administration into the quadratus lumborum (QL) inter-fascial plane in canine cadavers and assessing the spread along the vertebral bodies (VBs) by computed tomography (CT). Phase 1: eight canine cadavers received one catheter per hemiabdomen, followed by injection of contrast media solution [low volume (LV) 0.3 mL kg−1 or high volume (HV) 0.6 mL kg−1]. Phase 2: postoperative pain of five dogs was managed by injecting 0.3 mL kg−1 of ropivacaine 0.5% through QL catheters every eight hours, up to 72 h after abdominal surgery. Pain was assessed using the Short Form of the Glasgow Composite Measure Pain Scale, and methadone 0.2 mg kg−1 was administered intravenously when the pain score was ≥6. The number of VBs stained by the contrast solution between the QL and psoas minor muscles was significantly higher in group HV than group LV. The catheter tip was visualized in the retroperitoneal space in 1/16 and 2/10 hemiabdomens in phases 1 and 2, respectively. Rescue analgesia was required in 3/5 dogs during the postoperative period. The QL catheter placement technique appears feasible and may be included in a multimodal analgesic approach for dogs undergoing abdominal surgeries. Full article

The aim of this prospective, randomized clinical trial was to evaluate the use of the pleth variability index (PVi) to guide the rate of intraoperative fluid therapy compared to a traditional fixed-fluid-rate approach in ASA 1–2 dogs undergoing surgery. Twenty-seven dogs met the inclusion criteria and were randomly assigned to the conventional fluid management group (CFM, n = 12) or the PVi-guided group (PVi, n = 15). The CFM group received a fixed rate of 5 mL kg−1 h−1 of crystalloid solution, while in the PVi group the rate was continuously adjusted based on the PVi: PVi < 14% = 3 mL kg−1 h−1; 14% ≤ PVi ≥ 20% = 10 mL kg−1 h−1; and PVi > 20% = 15 mL kg−1 h−1. Hypotension (MAP < 65 mmHg) in the CFM was treated with a maximum of two fluid boluses (5 mL kg−1 in 10 min) and in the case of no response, dobutamine (1–3 mcg kg−1 min−1) was administered. In the PVi group, the treatment of hypotension was similar, except when the PVi > 14%, when dobutamine was started directly. Total fluid volume was significantly lower in the PVI group (0.056 ± 0.027 mL kg−1 min−1) compared to the CFM group (0.132 ± 0.115 mL kg−1 min−1), and the incidence of hypotension was lower (p = 0.023) in the PVi group (0%) compared to the CFM group (41%). The mean arterial pressure (MAP) was significantly higher in the PVi group during surgery. Dobutamine was never administered in either group. Preliminary data suggest that the PVi may be considered as a potential target to guide fluid therapy in dogs; larger studies are needed, especially in cases of cardiovascular instability.
