“…While a median of 25–26 min was required to perform the TAP and the intercostal blocks in the study by Paolini et al [ 19 ], accomplishing the four TAP blocks of this study took a mean of 12 min. This time is close to the range of time between 48 and 120 s required to complete a single TAP block described in a study on cadavers [ 25 ]. The operator’s experience seems decisive in shortening the completion time [ 26 ].…”

The transversus abdominis plane (TAP) block causes desensitization of the abdominal wall and peritoneum. Of all the approaches proposed to perform it, the two-injection-point TAP showed the best results in terms of the area reached by the anesthetic solution. However, to date, no clinical data exist. The aim of this study was to evaluate the intra- and postoperative analgesic efficacy of a two-injection-point TAP block in dogs undergoing laparoscopic ovariectomy. A total of 26 animals were assigned to receive general inhalation anesthesia (control group), and 26 dogs were assigned to general inhalation anesthesia combined with TAP block (TAP group). The ultrasound-guided TAP block was carried out with a subcostal and cranial-to-ilium injection per hemiabdomen. The end-tidal concentration of isoflurane (EtISO) was recorded at different moments during the surgery. Postoperative pain was assessed at different time points during the first 24 h after surgery. The control group required significantly higher EtISO concentration during the ovarian resection and showed higher postoperative pain scores than the TAP group. Fewer dogs in the TAP group required intra- or postoperative rescue analgesia. TAP block can be implemented to improve postoperative pain management after laparoscopy, reducing the dosage of the systemic drugs used and, hence, their possible side effects.

“…More recently, ultrasound-guided fascial plane blocks (injection of local anesthetic within a selected fascial plane to target nerves that run through that plane) are gaining popularity, [19][20][21][22][23] and a number of injection techniques are being described and successfully adapted from human anesthesia to be used in the dog. [24][25][26][27] Currently, there are no standards in veterinary anesthesia regarding ERAS protocols and locoregional anesthesia for individual surgical procedures; however, there is enough published literature and clinical information to make some informed recommendations. The use of long-acting local anesthetics such as bupivacaine or ropivacaine with the possible addition of coadjuvants such as dexmedetomidine is recommended since their prolonged analgesic effect will be carried over into the early postoperative period.…”

“…The TAP block is perhaps the best described and studied fascial plane infiltration in the dog to date and slight variations in the execution of this technique have been published. 27,34,[48][49][50] This block may be of particular interest in procedures involving the abdomen and abdominal wall, such as splenectomies, liver surgery as well as mass removals, herniorrhaphies, or laceration repairs among others. Its clinical use in dogs undergoing ovariohysterectomy has been recently reported.…”

Development of Enhanced Recovery After Surgery (ERAS) protocols in veterinary medicine through a one-health approach: the role of anesthesia and locoregional techniques

Enhanced Recovery After Surgery (ERAS) is a new and emerging concept in human medicine that involves rethinking the preoperative, intraoperative, and postoperative periods. The ultimate, overarching aim is to improve patient outcome following surgery and, thus, return to a normal daily routine as soon as possible. The development and implementation of locoregional anesthetic techniques in humans is one of the key elements driving these protocols. In veterinary medicine, we are no exception: the rapidly growing interest, development, and refinement of these techniques in our veterinary species is changing the way we think of anesthesia and analgesia. The potential real benefits are yet to be determined, as this concept is implemented into our veterinary hospitals in general, and our surgical patients in particular, in a more systematic and routine way. In this article, we will introduce the reader to the concept of ERAS protocols and the role of regional anesthesia in some common surgical procedures.

“…This technique involves positioning the patient in lateral recumbency while the US probe is placed in a transverse orientation to the spine, midway between the iliac crest and the last rib, lateral to the midline of the abdomen. This approach appears to be useful in the pain management of the caudal abdomen; however, the cranial spread of the LA does not appear to be sufficient to achieve the complete desensitization of the cranial abdominal wall [ 11 ]. Previous studies in human medicine have already shown that the use of the multi-point TAP block can guarantee a greater cranial and caudal spread compared to the single-point approach [ 12 ].…”

The aim of this study was to describe one-point (preiliac approach) and two-point (preiliac and retrocostal approach) blocks of the Transversus Abdominis Plane (TAP) on a cadaveric model. For this purpose, ultrasound-guided infiltration of the plane between the internal oblique and transversus abdominis muscles was performed and, after dissection of tissues, the areas and percentage of nerve fibers involved were analyzed. Injection into the TAP plexus of a 1 mL/kg solution of 2% lidocaine and 1% methylene blue (1:1) was performed in 30 rabbit cadavers. In fifteen rabbits (group S), the solution was inoculated at the preiliac level. In the other 15 rabbits (group D), the solution was divided into two inoculations (0.5 mL/kg at the retrocostal level and 0.5 mL/kg at the preiliac level). All cadavers were then dissected and stained spinal nerve branches were measured. Moreover, the percentage of length, height and the total area of the stained tissue were calculated. In the S group, T10, T11 and T12 nerve eminences were successfully stained in 18%, 52% and 75% of cases, respectively. Furthermore, L1, L2, L3 and L4 were stained in 95%, 100%, 60% and 40% of cases, respectively. In group D, the ventromedial eminence of T10, T11 and T12 were stained in 68.1%, 100% and 98% of cases, respectively, and L1, L2, L3 and L4 were stained in 88%, 100%, 62% and 31% of cases, respectively. In conclusion, a two-point TAP block is more effective in covering the nerve eminences of the cranial abdomen than the preiliac approach alone.
