Randomized Controlled Trial Comparative Study Clinical TrialComparison of anesthetic effect between 0.375% ropivacaine versus 0.5% lidocaine in forearm intravenous regional anesthesia.
Ropivacaine was shown to provide superior postblock analgesia to lidocaine in intravenous regional anesthesia (IVRA) in voluntary studies. The objective of this study was to compare the anesthesia efficacy, postblock analgesia, and local anesthetic-related side effects between ropivacaine and lidocaine when forearm IVRA was used. ⋯ We conclude that 0.375% ropivacaine provides effective anesthesia and superior postoperative analgesia compared with 0.5% lidocaine when forearm IVRA is used.

Assessment of lower extremity nerve block: reprise of the Four P's acronym.
Successful performance of lower-extremity regional anesthesia includes sensory and/or motor block assessment of up to 4 major peripheral nerves. This brief report describes a methodology for the rapid evaluation of lower-extremity anesthesia before surgical incision. ⋯ Accurate assessment of lower-extremity regional anesthesia can be achieved rapidly using The Four Ps evaluation tool.

ReviewCardiac toxicity of local anesthetics in the intact isolated heart model: a review.
An editorial in 1979 by George Albright about sudden cardiac arrest after regional anesthesia spawned an era of intense research focusing on what local anesthetics do to the heart and how they do it. The ultimate goal of the research was to bring to the clinician long-acting local anesthetics that are less cardiotoxic than ones available before 1979, bupivacaine and etidocaine, in particular. In this article, I will review results of studies of local anesthetic cardiotoxicity using the intact mammalian heart in vitro published after the Albright editorial through 2001.
