Randomized Controlled Trial
Anterior Quadratus Lumborum block area comparison in the three different volumes of Ropivacaine: a double-blind, randomized controlled trial in healthy volunteers.
In abdominal surgery, ultrasound-guided anterior quadratus lumborum blocks (QLB) are performed to induce analgesia. However, no study reported suitable volumes of the anterior QLB for the different postoperative analgesia regions. Therefore, this prospective randomized controlled study assessed the dermatomal spread and analgesic effects of the three different volumes of a local anesthetic for anterior QLB. ⋯ No difference was observed in block duration with the various volumes of 0.375% ropivacaine. However, the larger volume for anterior QLB contributed to a larger area of cutaneous sensory blockade. Appropriate volumes in anterior QLB can create suitable postoperative analgesia levels for the different operative sites.

Observational Study
The effect of intraoperative lidocaine administration in a disrupted erector spinae fascial plane on intercostal transcranial motor evoked potentials.
Erector spinae plane (ESP) blocks have been recently described for postoperative pain management following spine surgery but their effects on intraoperative neuromonitoring are unknown. ⋯ The administration of a local anesthetic into a disrupted erector spinae fascial plane does not appear to interfere with intraoperative neuromonitoring of posterior spine fusion surgeries.

Is erector spinae plane (ESP) catheter insertion within 24 h of hospital admission for rib fractures associated with a lower incidence of respiratory complications compared to those having an ESP within 48 h or after 48 h of admission. ⋯ The performance of an ESP block after 48 h of admission was associated with an increased incidence of respiratory complications and ICU length of stay. There appears to be no added benefit associated with the provision of a prompt ESP within 24 h.
