Review Meta AnalysisAnterior quadratus lumborum blocks for postoperative pain treatment following intra-abdominal surgery: A systematic review with meta-analyses and trial sequential analyses.
The anterior quadratus lumborum (QL) block may be used for postoperative pain management for intra-abdominal surgeries, but the evidence is uncertain. We aimed to investigate the benefit and harm of the anterior QL block compared to placebo/no block for intra-abdominal surgery. ⋯ The anterior QL block may reduce cumulative 24-h opioid consumption. Reported serious adverse events were few and the anterior QL block may have little to no effect on the number of SAEs, but the evidence was very uncertain.

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.

Observational Study
Analgesia-nociception index accurately predicts inadequate pectoralis muscle fascia block (PECS) in patients undergoing breast surgery: A prospective observational study.
Postoperative opioid administration has been largely replaced by regional anesthesia techniques. We aimed to determine whether intraoperative Analgesia-Nociception Index (ANI) can aid in early evaluation of the effectiveness of regional blocks such as the pectoralis muscle fascia block (PECS, pectoserratus and interpectoral plane blocks) and predicting the need for analgesics postoperatively. ⋯ The intraoperative ANI nadir <50 was strongly correlated with need for postoperative opioids. The ANI may aid in objectively evaluating the effectiveness of pectoralis muscle fascial blocks and predicting postoperative need for analgesics.
