The evidence supporting the benefit of femoral nerve block (FNB) for positioning before spinal anesthesia (SA) in patients suffering from a femur fracture remains inconclusive. In the present study, the authors intended to determine the efficacy and safety of FNB versus an intravenous analgesic (IVA) for positioning before SA in patients with a femur fracture. ⋯ Compared to IVA, FNB was an effective and safe strategy for the positioning of femur fracture patients for a spinal block, particularly patients who received SA in the sitting position.

Total knee arthroplasty is a treatment option for debilitating arthritis. In the postoperative period, patients experience moderate to severe pain affecting the rehabilitation, hospital stay, and patient satisfaction. This study aims at utilizing current best evidence to determine whether adductor canal block (ACB) or periarticular injection (PAI) is a better modality for managing short-term postoperative pain and opioid consumption. ⋯ PAI could significantly improve postoperative pain and opioid consumption when compared with ACB. Additional, high-quality studies are required to further address this topic.

Fascia iliaca compartment block (FICB) provides an analgesic option for positioning before spinal anesthesia in patients suffering from a femur fracture. The evidence supporting FICB is still not well established. The aim of our study is to assess the efficacy and safety of FICB comparing with intravenous analgesic (IVA) on the quality for positioning before spinal anesthesia in participants with a femur fracture. ⋯ Three studies comprising 141 participants showed that FICB compared to IVA led to a significant between-group standard mean differences in quality during positioning within 30 minutes before spinal anesthesia (standardized mean difference (SMD) -2.02, 95% confidence interval (CI): -2.43 to -1.61, I = 0%) and time for spinal anesthesia (pooled mean difference (PMD) -2.86 minutes, 95% CI -3.70 to -2.01, I = 0%). Two studies with 101 participants suggested that FICB is superior to IVA on opioid requirements 24 hours postoperatively (pooled odds ratio (POR): 0.11, 95% CI: 0.03 to 0.35, I = 13%). There were no significant differences in complications or hemodynamic effects CONCLUSIONS:: Comparing with IVA, FICB can provide significantly better quality during positioning of femur fracture patients for a spinal block and a shorter time for spinal anesthesia. FICB is safe method.

Meta Analysis
The efficacy of thoracic paravertebral block for thoracoscopic surgery: A meta-analysis of randomized controlled trials.
The efficacy of thoracic paravertebral block for thoracoscopic surgery remains controversial. We conduct a systematic review and meta-analysis to explore the impact of thoracic paravertebral block on thoracoscopic surgery. ⋯ Thoracic paravertebral block can substantially enhance pain management for thoracoscopic surgery.

Dexmedetomidine has been used as an adjuvanty added to local anesthetics to prolong analgesia following peripheral nerve blockade. The aim of this meta-analysis was to investigate the effect and safety of dexmedetomidine added to ropivacaine in brachial plexus block (BPB). ⋯ Dexmedetomidine added to ropivacaine in BPB has a better analgesia effect (shorter onset time and longer duration) compared to ropivacaine alone. At the same time, there was no difference in the incidence of bradycardia and hypotension.
