The costotransverse foramen (CTF) is a space continuous with the paravertebral space. We hypothesized that injections passing through the CTF will result in a successful injectate spread to the paravertebral space. ⋯ Thoracic vertebrae, rib cage, paraspinal muscle, nerve block, joints.

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.

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.
