Modified thoracoabdominal nerve block through perichondrial approach (M-TAPA): an anatomical study to evaluate the spread of dye after a simulated injection in soft embalmed Thiel cadavers.
There is still no consensus on the analgesic range and mechanisms of action of modified thoracoabdominal nerve block through perichondrial approach (M-TAPA). This cadaveric study aimed to determine the spread of an injectate following simulated M-TAPA. ⋯ Our findings suggest that M-TAPA most likely involves the T9, T10 and T11 segmental nerves and that the local anesthetic may not spread to the intercostal space in the thoracic cage in M-TAPA. Further studies are required to confirm the precise mechanism of action and efficacy of M-TAPA in a large sample of human participants.

Ultrasound-guided scalp nerve block in anesthesia of children receiving cranial suture reconstruction.
Analgesia is very important for children with craniosynostosis who are undergoing cranial suture reconstruction. This study investigated the effectiveness and safety of an analgesic technique based on scalp nerve block combined with general anesthesia versus general anesthesia alone. ⋯ Preoperative scalp nerve block can reduce hemodynamic fluctuation and postoperative pain in children undergoing cranial suture reconstruction for craniosynostosis. Thus, it can be safely and effectively applied in the anesthesia of these children.

Serum concentrations of local anesthetics after unilateral interpectoral-pectoserratus plane block in breast cancer surgery: a pharmacokinetic study.
The ultrasound-guided interpectoral-pectoserratus plane block is a fascial plane block for superficial surgery of the anterolateral chest wall. This technique involves injecting a relatively large volume of local anesthetics (typically 30 mL of 0.25%-0.50%, ie, 75-150 mg ropivacaine) underneath the major and minor pectoral muscles of the anterior thoracic wall. There is a potential risk of toxic serum concentrations of local anesthetics due to systemic absorption. ⋯ This pharmacokinetic study demonstrated that a 2.5 mg/kg ropivacaine interpectoral-pectoserratus plane block may result in exceeding the threshold for local anesthetic systemic toxicity.
