Randomized Controlled Trial Comparative Study
Comparison of the effects of perineural or intravenous dexamethasone on low volume interscalene brachial plexus block: a randomised equivalence trial.
There is no clinically significant difference in the duration of low-dose interscalene block between perineural and intravenous dexamethasone.

Randomized Controlled Trial
Quadratus lumborum block for analgesia after caesarean section: a randomised controlled trial.
Quadratus lumborum block has been shown to provide satisfactory analgesia after caesarean section performed under neuraxial anaesthesia. However, its efficacy has not been demonstrated in patients who have received intrathecal morphine. The aim of this study was to assess the efficacy of quadratus lumborum block as part of a multimodal analgesic regimen including intrathecal morphine. ⋯ There was a reduction in median (IQR [range]) visual analogue scale pain scores at 6 h with quadratus lumborum block compared with sham block both at rest (6 (0-14 [0-98]) mm vs. 14 (3-23 [0-64]) mm (p = 0.019); and on movement: 23 (10-51 [0-99]) mm vs. 44 (27-61 [2-94]) mm; (p = 0.014)). There was no difference in pain scores at any other time-point up to 48 h. When used in conjunction with intrathecal morphine and spinal anaesthesia, bilateral quadratus lumborum block does not reduce 24-h morphine consumption after caesarean section.

Finger injuries are commonly attended to in the emergency department, and digital nerve block is a frequently performed procedure for such injuries. This study compared the efficacy levels of the subcutaneous method according to the different injection sites. ⋯ Injection into the PIP joint showed the same anesthetic effect as injection into the MCP joint, but this effect occurred faster in the former.

Randomized Controlled Trial
The impact of ultrasound-guided continuous serratus anterior plane block versus intravenous patient-controlled analgesia on the incidence and severity of post-thoracotomy pain syndrome: A randomized, controlled study.
The aim of this randomized controlled trial was to evaluate U/S guided serratus anterior plane catheter block (SAPB) versus patient-controlled analgesia (PCA) on the emergence of post-thoracotomy pain syndrome (PTPS) after thoracotomies for thoracic tumours. ⋯ The current work hypothesized that SAPB for a week postoperatively, is a good loco-regional alternative for post-thoracotomy analgesia following thoracotomies for chest malignancies, it may reduce the emergence of PTPS and the demand for pain therapy in these patients.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of continuous transversus abdominis plane block, epidural or patient-controlled analgesia for patients undergoing laparoscopic colorectal cancer surgery.
The optimal analgesia regimen after laparoscopic colorectal cancer surgery is unclear. The aim of the study was to characterize the beneficial effects of continuous transversus abdominis plane (TAP) blocks initiated before operation on outcomes following laparoscopic colorectal cancer surgery. ⋯ Continuous TAP analgesia not only improved gastrointestinal motility but also shortened duration of hospital stay. A decreased opioid requirement and attenuating surgical stress response may be potential mechanisms. Registration number: ChiCTR-TRC-1800015535 ( http://www.chictr.org.cn).
