Meta AnalysisPeripheral Nerve Block Combined with Low-Dose General Anaesthesia in Elderly Patients Receiving Hip Arthroplasty.
The study assessed the effectiveness and safety of nerve block combined with low-dose general anaesthesia in elderly hip arthroplasty patients, conducted by a meta-analysis of RCTs. Six trials involving 403 patients were identified from databases such as Cochrane, MEDLINE, and PubMed. The results demonstrated a statistically significant difference in pain scores at postoperative 12hours (95% CI, -2.39 to -0.35, p = 0.008) and 24hours (95% CI, -1.86 to -0.50, p = 0.0007). ⋯ However, between the two groups, there was no statistically significant difference in the 48hour pain score (95% CI, -2.58 to 0.62, p = 0.23). Essentially, this approach effectively reduces early post-surgical pain and it minimises anaesthetic use, whilst simultaneously lowering the risk of complications. Key Words: Nerve block, Elderly patients, Hip arthroplasty, Pain, Postoperative complication.

A brachial plexus block plays an important role in providing perioperative analgesia for shoulder surgery; however, the inherent risk of phrenic nerve block and resulting hemidiaphragmatic paralysis may limit its use in patients with compromised pulmonary function. This study aimed to evaluate the safety, efficacy, maximum tolerated volume, and optimal biologic volume of 0.5% ropivacaine used in a single-injection retroclavicular brachial plexus block for arthroscopic shoulder surgery. ⋯ A single-injection retroclavicular brachial plexus block using 25 ml of 0.5% ropivacaine produced consistent block success with a minimal hemidiaphragmatic paralysis rate, suggesting the need for further studies to confirm this result in arthroscopic shoulder surgery.

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.
