Randomized Controlled TrialGreater occipital nerve block modulates nociceptive signals within the trigeminocervical complex.
The pharmacological block of the greater occipital nerve has been proven effective in numerous headache and facial pain syndromes. This clinical effect supports the hypothesis of a strong functional interaction between the occipital and trigeminal nerves which has been proposed in neurophysiological in vivo experiments in rodents. Although it is likely that the interaction has to occur in the central nervous system, the exact site and the mechanisms of the interaction remain largely unknown. ⋯ These data suggest that the functional inhibition of the occipital nerve block on trigeminal nociceptive activity is likely to occur at the C2 level where the occipital nerve enters the trigeminocervical complex and converges on the same central nuclei before the signal crosses the midline at that level and is then transmitted to higher processing centres.

Randomized Controlled TrialRandomized trial comparing the spread of erector spinae block with the combination of erector spinae block and retrolaminar block in soft embalmed Thiel cadavers.
Erector spinae plane (ESP) and retrolaminar (RL) blocks show unreliable spread. We hypothesize that the combination of ESP and RL blocks provides more extensive and reliable spread of dye than single ESP blocks. Our primary objective was to compare the spread of dye to the paravertebral spaces after the combination block and ESP block in Thiel embalmed cadavers. Spread, the primary end point, was defined as the number of paravertebral spaces colored with dye per injection. ⋯ In conclusion, the combination of ESP and RL blocks was more extensive and reliable than ESP block alone.

Erector spinae plane block reduces pain after laparoscopic cholecystectomy.
After laparoscopic cholecystectomy patients have moderate pain in the early postoperative period. According to several studies an erector spinae plane (ESP) block can be a valuable part of multimodal analgesia. Our intention was to evaluate how ESP block influences postoperative pain scores and opioid consumption after laparoscopic cholecystectomy. ⋯ An ESP block can provide superior postoperative analgesia and reduction in opioid requirement after laparoscopic cholecystectomy.

This study aimed to identify the benefits of quadratus lumborum block (QLB) in terms of postoperative analgesic effects in adult participants undergoing hip surgery. ⋯ Our meta-analysis showed that QLB when compared to no block clinically decreased opioid requirements, reduced PONV, and improved participants' satisfaction. QLB also seems to be significantly superior to no block in terms of pain score, but its clinical importance remains unclear.
