“…This suggests that, despite the high volume used, in a clinical context, a single injection of local anaesthetic would not be able to adequately cover all abdominal sensory branches in the TAP. Moreover, in agreement with the results of Zoff et al and Romano et al [16,23], we found a significant dorsoventral diffusion (44.48 ± 9.26 mm). This showed that the use of large volumes probably does not improve the craniocaudal spread (48.91 ± 7.56 mm) but induces diffusion of local anaesthetic evenly over the entire abdominal wall.…”

“…Compared to classic neuraxial techniques, fascial plane blocks are considered at low risk of nerve injury and relatively easy to perform; however, it should be emphasised that the TAP block only provides somatic analgesia (from the ventrolateral skin of the abdomen to the peritoneum); therefore, during surgery involving visceral pain, systemic drugs are needed to achieve adequate analgesia [15,23]. Either way, according to the current literature in human and veterinary medicine, the TAP block has been demonstrated to produce great results as part of a multimodal approach in the management of perioperative abdominal pain [15][16][17]24].…”

The aims of the study were to describe the ultrasonographic-guided lateral TAP block in rabbit cadavers and evaluate the spread of a lidocaine/methylene blue solution through a single fascial infiltration. The US-guided block and anatomical dissections were performed in 17 New Zealand rabbit cadavers. The probe was placed perpendicular to the column, one centimetre ventrally to the transverse processes, halfway between the iliac crest and the costal margin. External oblique (EO), internal oblique (IO), and transversus abdominis (TA) muscles were visualised, and 1 mL/kg of lidocaine 2% plus methylene blue 1% was injected. After dissection, the branches of spinal nerves stained were measured. Moreover, the percentage of length and height of the area marked were calculated. A good visualisation of the TAP was obtained in all 34 hemiabdomens. T11 nerve eminence was successfully stained in 52% of cases. T12, L1, and L2 were stained in 75%, 95%, and 100% of cases, respectively. L3 and L4 were stained in 60% and 40% of cases, respectively. The lateral TAP block with a single point of injection can be easily performed in rabbits, but it is not sufficient to cover the nerve eminences of the cranial abdomen. The two-point TAP block (lateral and subcostal) could represent a better option, particularly when large surgical incisions are required.

“…Conflicting evidence about the effect of the injected volume on the spread of the solution have been reported in both humans (Carney et al 2011;Moeschler at al. 2013;Forero et al 2015) and dogs (Bruggink et al 2012;Zoff et al 2017b).…”

TAP injections were easy to perform with both techniques in calf cadavers. The volume of injectate did not influence spread. The authors conclude that a combination of the two approaches is necessary, but perhaps not sufficient, to stain all of the nerves innervating the ventral abdominal wall. Further studies are required to refine the technique and evaluate its efficacy in preventing nociception in calves.

“…Injection in the TAP without optimal visualisation has been shown to correlate with inadvertent intra‐abdominal injection (Frigon and others 2006). Inadvertent puncture of abdominal organs has been described in humans undergoing a TAP block (Farooq and Carey 2008, Lancaster and Chadwick 2010, Zoff and others 2017) and thus this should be considered a risk that can be minimised by the use of ultrasound guidance and by avoiding the advancement of the needle without ultrasound visualisation of the tip. Inadvertent intra‐abdominal injection has been previously described in human medicine and was also seen in up to 25 per cent of the injections in canine cadavers (Zoff and others 2017).…”

A transversus abdominis plane (TAP) block was performed in two calves undergoing umbilical hernia repair. Both calves were in good health and body condition and were anaesthetised using standard anaesthesia protocols. After placement in dorsal recumbency, the abdomen was scanned with an 11-MHz linear array probe from the last rib to the iliac crest to identify the abdominal musculature comprising the external and internal abdominal oblique muscles and the transversus abdominis (TA). The needle (SonoTAP cannula 22G×50 mm; Pajunk) was advanced using an in-plane technique, and a volume of 0.3 ml/kg was injected after a test dose. No obvious reduction of isoflurane requirements was apparent and one of the calves required rescue analgesia. The calves recovered uneventfully from anaesthesia.This case report discusses the advantages of the TAP block over the paravertebral block, discusses the risks associated with TAP blocks and highlights the importance of training in ultrasound-guided techniques.

Comparison of the spread of two different volumes of contrast medium when performing ultrasound‐guided transversus abdominis plane injection in dog cadavers

Abstract: Injection of 1 mL/kg of diluted contrast did not result in wider cranio-caudal spread in the transversus abdominis muscle plane of dog cadavers when compared with 0 · 5 mL/kg. Intraperitoneal injection is a risk and might be reduced with good needle visualisation.
