Review Meta Analysis
Effect of perioperative systemic α2 agonists on postoperative morphine consumption and pain intensity: systematic review and meta-analysis of randomized controlled trials.
Systemic α2 agonists are believed to reduce pain and opioid requirements after surgery, thus decreasing the incidence of opioid-related adverse effects, including hyperalgesia. ⋯ Perioperative systemic α2 agonists decrease postoperative opioid consumption, pain intensity, and nausea. Recovery times are not prolonged. Common adverse effects are bradycardia and arterial hypotension. The impact of α2 agonists on chronic pain or hyperalgesia remains unclear because valid data are lacking.

High-volume hemofiltration is an extracorporeal therapy that has been available in the intensive care unit for more than 10 yr. Recent improvements in technology have made its clinical application easier and safer. ⋯ For patients with acute kidney injury requiring renal replacement therapy, the two largest multicenter studies performed to date established that high ultrafiltration flow rates are not necessary. Conversely, much experimental and some clinical evidence suggest that high-volume hemofiltration can be beneficial for the subset of critically ill patients with severe inflammatory states such as septic shock.
