Intraindividual variation of the transversus abdominis plane block: an exploratory study in healthy volunteers.
The transversus abdominis plane block is widely used in postoperative pain management after abdominal surgery. However, large interindividual variation in the cutaneous distribution area of the block has been demonstrated. The purpose of the present study was to explore the reproducibility of the block by determining the intraindividual variation when repeating the block on two separate days. ⋯ We found a moderate-to-good reproducibility for lateral abdominal muscle thickness during maximal voluntary contraction, but a moderate-to-poor reproducibility for all other block characteristics. However, the cutaneous distribution of the block was still located primarily inferior to a horizontal line through the umbilicus and lateral relative to a vertical line through the anterior superior iliac spine.

Randomized Controlled Trial
Randomized Controlled Trial Comparing Landmark and Ultrasound-Guided Glossopharyngeal Nerve in Eagle Syndrome.
The glossopharyngeal nerve lies posterior to the internal carotid artery at the submandibular region. The primary objective of this study was to compare ultrasound-guided glossopharyngeal nerve block (UGPNB) and landmark glossopharyngeal nerve block (GPNB). ⋯ UGPNB with 1.5 mL of 0.5% ropivacaine and 20 mg of methylprednisolone injected posterior to the ICA in the submandibular region provides better pain relief for at least a week compared with an extraoral landmark technique when three weekly consecutive blocks are given. In most patients, a curvilinear probe and out-of-plane needle trajectory are most suitable for ultrasound block.

Liposomal bupivacaine (LipoB), delivered via intercostal nerve blocks (ICNBs), is increasingly being used for postoperative pain control in thoracic surgery patients, but there is limited data on its effectiveness when compared to standard bupivacaine. ⋯ Intercostal nerve block, liposomal bupivacaine, RATS, regional anesthesia, robotic-assisted thoracoscopic surgery, thoracotomy, VATS, video-assisted thoracoscopic surgery.

The efficacy of quadratus lumborum muscle block (QLB) in abdominal surgery is known; however, the efficacy of different QLB types is unclear. The objective of this study was to investigate the effects of ultrasound-guided QLB type 2 and type 3 on postoperative opioid consumption and pain scores in patients undergoing inguinal hernia surgery. ⋯ The use of QLB2 and QLB3 decreased postoperative opioid consumption and pain scores in patients undergoing inguinal hernia surgery. Furthermore, QLB3 provided more effective and longer lasting postoperative analgesia and lower opioid consumption compared to QLB2.

Intrathecal morphine administration at the time of neuraxial anesthesia performance is the gold standard for post-cesarean delivery (CD) analgesia. When intrathecal morphine administration is inappropriate or contraindicated, the use of systemic analgesic options increase side effects and risks to both the parturient and the breastfeeding neonate. Moreover, systemic analgesia is often inadequate. ⋯ Some may prove to be superior to the TAP block. These techniques include: ilioinguinal/ilio-hypogastric nerve blocks (II-IH), the quadratus lumborum (QL) blocks and the erector spinae plane (ESP) block. In this review, we will discuss and assess these techniques regarding analgesia following CD.
