Review Meta Analysis
Efficacy of pregabalin in acute postoperative pain: a meta-analysis.
Multimodal treatment of postoperative pain using adjuncts such as gabapentin is becoming more common. Pregabalin has anti-hyperalgesic properties similar to gabapentin. In this systematic review, we evaluated randomized, controlled trials (RCTs) for the analgesic efficacy and opioid-sparing effect of pregabalin in acute postoperative pain. ⋯ Pregabalin reduced opioid-related adverse effects such as vomiting [risk ratio (RR) 0.73; 95% confidence interval (CI) 0.56-0.95]. However, the risk of visual disturbance was greater (RR 3.29; 95% CI 1.95-5.57). Perioperative pregabalin administration reduced opioid consumption and opioid-related adverse effects after surgery.

Review Multicenter Study
Complications related to less-invasive haemodynamic monitoring.
The aim of this study was to evaluate the type and incidence of complications during insertion, maintenance, and withdrawal of central arterial catheters used for transpulmonary thermodilution haemodynamic monitoring (PiCCO™). ⋯ In this series of patients, central arterial catheters used for PiCCO™ monitoring were demonstrated to be a safe alternative for advanced haemodynamic monitoring.

As ropivacaine and its metabolites are excreted by the kidneys, we studied their disposition in subjects with renal dysfunction. ⋯ The pharmacokinetics of ropivacaine is not affected by renal failure. Although the renal clearance of PPX correlates with CL(CR), non-renal elimination seems to compensate for reduced renal clearance in most patients. PPX may accumulate in plasma during long-term postoperative infusions, in particular in patients with co-existing low non-renal elimination. Systemic toxicity is still unlikely because PPX is markedly less toxic than ropivacaine.
