“…Our results confirm the multi-segmental distribution of the methylene blue-lidocaine solution along the TTP using a transverse approach, and the staining of a greater number of nerves when increasing the injected volume, suggesting that the t-TTP described might decrease the number of injections necessary to desensitize the intercostal nerves involved in ventral chest wall innervation. Conversely, Ueshima and Otake [21] have reported a wider spread of the injectable solution by a sagittal approach than by a transverse approach in a human clinical study.…”

“…Traditionally in human medicine, parasternal block consists in multiple intercostal blocks just lateral to the sternal border, injecting an anaesthetic solution between the pectoralis profunda and the intercostal muscles [3,16,26]. Although the authors refer to this technique as a parasternal approach, we believe that corresponds to the sagittal TTP approach described in human literature [3,21]. In this study, Zublena et al [22] evaluated the spread of a dye solution along the TTP and the staining of the intercostal nerves when two different volumes (0.05 mL kg −1 and 0.1 mL kg −1 ) were injected.…”

“…Sagittal and transverse approaches to TTP block have been reported in human literature [21]. The sagittal approach was recently described in veterinary literature [22]; however, to our knowledge, there are no references to the ultrasound-guided transverse approach to the transversus thoracis plane (t-TTP).…”

Transversus thoracis plane (TTP) block has demonstrated to produce analgesia in humans undergoing median sternotomy. The objectives of the study were to describe an ultrasound-guided transverse approach to the transversus thoracis plane (t-TTP) and to evaluate the spread of two injectable volumes in canine cadavers. Two cadavers were used to describe relevant gross anatomy of the ventral thoracic area and sonoanatomy between the fifth and sixth costal cartilages. Then, eight cadavers were used to describe the ultrasound-guided injection into the TTP and were dissected to evaluate the injectate spread and the intercostal nerves staining with two different dye-lidocaine volumes: low volume (LV) 0.5 mL kg−1 and high volume (HV) 1 mL kg−1. To compare the spread between both volumes the Fisher’s exact test and Wilcoxon signed-rank test were used. The solution spread along the TTP after all injections, staining a median number (range) of 3 (2–4) and 4 (3–5) nerves with LV and HV, respectively (p = 0.014). The injection of HV versus LV increases the number of stained nerves. Ultrasound-guided t-TTP is a feasible technique that provides staining of several intercostal nerves with a single injection site, so it could be useful to provide analgesia to the ventral chest wall.

The transversus thoracis muscle plane block (TTP) block is a newly developed regional anesthesia technique which provides analgesia to the anterior chest wall. Since its introduction, this technique has been utilized for a wide range of surgical procedures as well as nonsurgical indications. Current evidence suggests that the TTP block provides effective analgesia for breast and cardiac surgeries, cardiac device implantation, pericardiocentesis, and acute and chronic pain management. To date, no major complications have been reported. Currently there is an urgent need to standardize the nomenclature of this technique to facilitate accurate communication amongst care providers, researchers, and authors. In this review, we describe the TTP block technique, review the indications and available evidence in clinical practice, and discuss alternative blocks and future prospects.
