“…Two different case series have investigated the analgesic efficacy of serratus plane block 18 and erector spinae plane block 19 in dogs submitted to lateral thoracotomy. More recently, another case series reported the use of erector spinae plane block in combination with a constant‐rate infusion of dexmedetomidine in dogs submitted to sternotomy 20 . In veterinary medicine, two different approaches for US‐guided blocks have been described in dogs 6–8 to provide analgesia during median sternotomy.…”

“…More recently, another case series reported the use of erector spinae plane block in combination with a constant-rate infusion of dexmedetomidine in dogs submitted to sternotomy. 20 In veterinary medicine, two different approaches for US-guided blocks have been described in dogs [6][7][8] to provide analgesia during median sternotomy. These techniques consist of injecting local anaesthetic (LA) in the vicinity of the distal portion of the intercostal nerves, between the internal intercostal muscle and the transversus thoracis muscle, either via a parasagittal approach 6 or via a transversal approach.…”
A 3.25-kg, 1-year-old, European shorthair cat was referred for acute respiratory distress. A thoracic computed tomography revealed the presence of multiple pulmonary abscesses, and a median sternotomy for pulmonary lobectomy was scheduled. The cat was premedicated with methadone and dexmedetomidine, anaesthesia was induced with alfaxalone and maintained with isoflurane in 100% oxygen. Ultrasound-guided parasternal block was performed before surgery with ropivacaine 0.5% (total dose 3 mg/kg). Rescue analgesia was needed only during abscess debridement and lung lobectomy. Postoperative pain was assessed every hour, using the short-form Glasgow Feline Composite Measure Pain Scale. The cat required rescue analgesia (0.2 mg/kg methadone) 7 hours after the completion of the block. This case report describes the feasibility of ultrasound-guided parasternal block in a cat undergoing median sternotomy, suggesting that it can usefully be added to a multimodal analgesic plan in the perioperative period.

“…One of the great advantages of local anesthetic (LA) use is the blockage of sodium channels in order to prevent the "memory of the nociceptive stimuli and pain" [4]. In recent years, clinical studies on loco-regional anesthesia in dogs have focused on interfascial plane (IFP) techniques such as the Trasversus Abdominis plane (TAP) block, Erector Spinae plane (ESP) block, the Serratus plane (SP) block, and the Quadratus Lumborum (QL) block [20][21][22][23][24][25]. The IFP blocks are relatively simple to perform, with a high rate of success.…”
In veterinary medicine, the use of loco-regional anesthesia techniques is increasing. The Quadratus Lumborum block (QL) is an interfascial loco-regional technique that involves the release of local anesthetic (LA) between the Quadratus Lumborum and the Small Psoas (Pm) muscle. The study aims to evaluate the effect of the QL block on reducing the total amount of opioids in dogs undergoing pre-scrotal orchiectomy. A group of 36 dogs was enrolled in a randomized blinded study. The animals were divided into two groups: 18 in the experimental group (QL) and 18 in the control group (C). The QL group received 0.4 mL kg−1 of ropivacaine 0.5% for each hemiabdomen (total amount of 3 mg kg−1 of ropivacaine, 1.5 mg kg−1 per side). The C group was brought into the operating room (OR) after receiving the same clipping as the QL group. In the intraoperative period, opioid consumption in the QL group was significantly lower than in the C group. No differences were found in the post-operative phase. No side effects were reported when performing the QL technique. The QL block performed at the level of L6 appears to be a valid approach to reducing opioid use in dogs undergoing orchidectomy with a pre-scrotal surgical approach.
“…The thoracic epidural anaesthesia has also been reported, although it carries technique-and drug-related risks of severe complications. 1 Other local anaesthetic techniques have been clinically described in veterinary medicine to provide analgesia to the ventral chest wall, including thoracic paravertebral block, 6 erector spinae plane block 7 and pecto-intercostal block. 8 The transversus thoracic muscle plane (TTP) block is a regional anaesthesia technique used in human medicine with the main objective of providing perioperative analgesia in patients undergoing procedures such as sternotomy, sternal retraction, internal mammary artery harvesting, chest tubes placement and cardiac surgery.…”

A 12‐year‐old, neutered, male, domestic shorthair cat presented for investigation of acute‐onset respiratory distress and cough. Computed tomography scan showed bilateral pleural effusion and dorsal elevation of the trachea compatible with a mass effect. A median sternotomy was performed. Anaesthetic protocol consisted of premedication with intravenous methadone (0.2 mg/kg), induction with alfaxalone to effect and maintenance with isoflurane in oxygen. Transversus thoracic muscle plane block was performed injecting 0.4 mL/kg of 0.25% bupivacaine per side. Fentanyl (2 μg/kg) was administered as rescue analgesia once during surgery. The Glasgow Composite Pain Scale was assessed postoperatively. Methadone was given as rescue analgesia postoperatively when Glasgow pain score was greater than 5/20. The first administration of methadone was required at 8 hours after the transversus thoracic muscle plane block was performed. This case showed that the ultrasound‐guided transversus thoracic muscle plane block is a feasible technique in feline patients as part of a multimodal analgesia plan in a cat undergoing sternotomy.
