Randomized Controlled Trial
Ultrasound-guided Double-point Versus Single-point Serratus Anterior Plane Block for Modified Radical Mastectomy: A Randomized Controlled Trial.
The double-point serratus anterior plane block (SAPB) covers more area, including the axilla, than the single-point approach, potentially offering better pain relief after modified radical mastectomy (MRM). The objective of this study were to evaluate the clinical outcomes of these 2 procedures for patients treated with MRMs. ⋯ Double-point SAPB offers wider anesthetic spread but shows no significant clinical advantage in pain or axillary comfort over single-point SAPB after MRM.

A randomized clinical trial comparing different combination of peripheral nerve blocks for intraoperative analgesia in patients on antithrombotic drugs undergoing hip fracture surgery: pericapsular nerve group (PENG) block versus femoral and obturator nerve block.
Locoregional anesthesia is commonly used in orthopedic trauma surgery, particularly in elderly patients. We conducted a prospective, monocentric, randomized controlled trial to evaluate the anesthetic and analgesic efficacy of pericapsular nerve group (PENG) block in patients on antithrombotic drugs undergoing hip fracture surgery, comparing it with femoral and obturator nerve block (FNB+ONB). ⋯ Our results suggest that PENG block is not inferior to FNB + ONB as anesthetic and analgesic technique in patients on antithrombotic drugs undergoing hip fracture surgery.

New insights into the use of dexamethasone-dexmedetomidine as perineural adjuvants in peripheral nerve and fascial blocks: an up-to-date narrative review.
The discovery of the mechanism of action of local anesthetics, involving the blocking of sodium ion channels is considered a milestone in anesthesia. Potentially lethal toxic effects occur in the case of intravascular injection of local anesthetic (LA) or in case of exceeding dosages, as a result of systemic reabsorption. Attempts to prevent these life-threatening events have been made by developing novel LA and by adding adjuvants. ⋯ The addition of perineural dexamethasone-dexmedetomidine combination has shown a faster onset, longer duration of action and increased intensity of neuronal blockade of regional anesthesia compared to perineural single adjunct. This is consistent with clinical studies (trials, observational studies and reports) of a marked prolongation of the local anesthetic effect. Nevertheless, further studies are needed to ascertain the full potential of this technique and all possible associated risks.
