Review Meta Analysis
Effectiveness of Peripheral Nerve Blocks for the Treatment of Primary Headache Disorders: A Systematic Review and Meta-Analysis.
Primary headache disorders are prevalent and account for 2% of all emergency department visits. Current treatment options are effective; however, time to pain relief is suboptimal. Alternatives such as peripheral nerve blocks have shown promising results. The objective of this systematic review is to examine the effectiveness of peripheral nerve blocks for timely pain relief. ⋯ Our review shows peripheral nerve blocks are effective as a rapid treatment option when compared to placebo; however, we were unable to assess effectiveness against standard treatment. Emergency physicians should consider peripheral nerve blocks as an adjunct therapy for patients with primary headache disorders.

This study was designed to evaluate the efficacy of analgesia and incidence of postoperative nausea and vomiting (PONV) of several widely used clinical treatments for postoperative analgesia following abdominal surgery through network meta-analysis (NMA) based on published randomized controlled trials (RCTs). ⋯ The findings from our work provide evidence that preoperative paravertebral block was superior to continuous or postoperative wound infiltration to provide postoperative analgesia, nausea and vomiting after abdominal surgery.

Effect of superior trunk block on diaphragm function and respiratory parameters after shoulder surgery.
The interscalene brachial plexus block has been used effectively for intraoperative and postoperative analgesia in patients undergoing shoulder surgery, but it is associated with high rates of diaphragmatic dysfunction. Performing the block more distally, at the level of the superior trunk, may reduce the incidence of phrenic nerve palsy. We hypothesized that superior trunk block would result in diaphragmatic paralysis rate of less than 20%. ⋯ Although injection of local anesthetic at the superior trunk level is associated with less diaphragmatic paralysis compared with traditional interscalene block, a significant portion of patients will continue to have ultrasonographic and clinical evidence of diaphragmatic weakness or paralysis.
