Summary: This study examined the dye spread of an ultrasound-guided DPIP block in a human cadaveric model, finding that the block spread along the tissue plane above the transversus thoracis muscles to multiple levels, dyeing the intercostal nerves. This block may have clinical value for analgesia in anterior thoracic surgical procedures.

Summary: This study aimed to assess the cutaneous sensory block area (CSBA) after ultrasound-guided transversus abdominis plane block (TAP) using the subcostal approach. The researchers found that the subcostal TAP resulted in a heterogeneous non-dermatomal CSBA with varying size and distribution across the medial abdominal wall.

Summary: The distance from the sacrococcygeal membrane to the dural sac can be measured using ultrasound imaging, which helps to prevent dural puncture in caudal epidural analgesia.

Summary: Regional anesthesia (RA) is a valuable technique for pain control in different patient populations. During the COVID-19 pandemic, the demand for RA has increased due to its potential to reduce the risk of cross-infection. Perfusion index (PI), a non-invasive and objective parameter, has shown promise in early identification of RA effectiveness, offering timely decision-making for physicians.

Summary: This study proposed a simple clinical scoring system to predict the difficulty of lumbar spinal anesthesia, finding that the combination of multiple factors increased the chance of a second skin puncture success.

Summary: By injecting the dye solution into the interfascial plane between the infraspinatus and teres minor, the suprascapular and axillary nerves, which innervate the glenohumeral joint, can be reached.

Summary: Four patients with refractory rotator cuff disease underwent ultrasound-guided cryoablation of the capsular branches of the shoulder joint, leading to at least 60% pain relief and functional improvement for 6-12 months without any motor impairment.

Summary: This pilot cadaveric study aimed to determine the optimal injection techniques for parasternal intercostal plane (PIP) block. The study found that triple injections at the second, fourth, and fifth intercostal spaces for the superficial approach and double injections at the third and fifth intercostal spaces for the deep approach were the optimal techniques for PIP blocks. The distribution of dye was more localized in the superficial block.

Summary: This study investigated the dye spread of ultrasound-guided thoracic ESP block at two different needle locations using cadaveric models. The results showed that ESP injection administered between transverse processes exhibited more extensive spread compared to medial transverse process injection in a cephalocaudal direction.

Summary: This study found that increasing the injection volume can result in a wider spread of anesthetic in erector spinae plane (ESP) blocks. An injection volume of 30 mL may be optimal for ESP blocks requiring analgesia across 4-7 levels.

Summary: This research investigates the optimal animal species and needle configuration for extrapolating intraneural injection outcomes to human contexts. The findings indicate that using animal models with monofascicular or oligofascicular nerves (such as rats, rabbits, and dogs) may compromise the reliability of intraneural injection outcomes when the needle aperture dimensions exceed those of the fascicles.

Summary: This study compared the analgesic effects of pre-operative and postoperative transversus abdominis plane (TAP) block after laparoscopic cholecystectomy. The findings suggest that postoperative TAP block may be slightly more effective in reducing opioid consumption and postoperative nausea and vomiting (PONV) compared to pre-operative TAP block, but there is no significant difference in postoperative pain.

Summary: Peripheral nerve injury or post-block neurological dysfunction (PBND) is a recognized complication of peripheral nerve blocks (PNB). This review provides insights into the incidence of PBND and its association with different PNBs. The study finds that PBND incidence decreases over time, and the use of ultrasound guidance may lower the incidence. Standardized reporting of PBND and its association with PNB is needed for future studies.

Summary: This international consensus study aimed to provide specific information for designing a non-fellowship regional anesthesia curriculum, with strong consensus reached on core peripheral and neuraxial blocks, as well as learning objectives and skills assessment. Participants from 66 countries highlighted the importance of practicing 16-20 peripheral blocks per anatomical region and a minimum of 50 neuraxial blocks to improve patient care through better training and quality of nerve blocks.

Summary: This study investigated the effects of hydrodissection on anesthesia characteristics in infraclavicular brachial plexus blockade. The results showed significant differences in sensory and motor block onset times and postoperative VAS scores between the hydrodissection and normal groups, indicating that hydrodissection can result in safer and more successful anesthesia. However, there were no significant differences in block application times, postoperative block removal times, and complications between the two groups.
