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.

A 46-year-old man presented with severe refractory posterior shoulder pain due to a left scapular fracture sustained during a motor vehicle collision. Despite multimodal oral and intravenous analgesics, the patient's pain remained difficult to control. A continuous paravertebral nerve block was performed between the second and third thoracic vertebrae resulting in excellent analgesia of the scapular pain. This case suggests that a continuous thoracic paravertebral block placed between the second and third vertebrae may be considered as part of multimodal analgesia in patients with scapular fractures.

Cancer-related abdominal and pelvic pain syndromes can be debilitating and difficult to treat. The objective of this study was to evaluate the efficacy of superior hypogastric plexus blockade or neurolysis (SHPN) for the treatment of cancer-related pelvic pain. ⋯ SHPN was an effective and relatively safe procedure for pain associated with pelvic malignancies. There is a need for larger prospective trials.

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.

Population Pharmacokinetics of Levobupivacaine During Transversus Abdominis Plane Block in Children.
Levobupivacaine is commonly used during transversus abdominis plane (TAP) block in pediatric patients. However, the dosing regimen is still empirical, and the pharmacokinetic properties of levobupivacaine are not considered. Here, the pharmacokinetics of levobupivacaine during an ultrasound-guided TAP block were evaluated to optimize dosing regimen, regarding the between-subject variability (BSV) and the volume of levobupivacaine injected. ⋯ For improved efficiency in the pediatric population, the dose of levobupivacaine should be greater than 0.4 mg/kg. Children's weight should be considered to anticipate any risk of toxicity.
