Active research fields in anesthesia: a document co-citation analysis of the anesthetic literature.
The expansion of science has resulted in an increased information flow and in an exponentially growing number of connections between knowledge in different research fields. In this study, we used methods of scientometric analysis to obtain a conceptual network that forms the structure of active scientific research fields in anesthesia. ⋯ Using co-citation analysis, we identified distinct homogenous clusters of highly cited documents representing 46 active current anesthetic research fields and determined multiple nets of knowledge among them.

Randomized Controlled Trial Comparative StudyIntraarticular injection of magnesium sulphate and/or bupivacaine for postoperative analgesia after arthroscopic knee surgery.
Intraarticular bupivacaine is often used for prevention of pain after arthroscopic knee surgery. Intraarticular magnesium, a N-methyl-D-aspartate receptor blocker, would be of particular interest in either producing postoperative analgesia or enhancing the analgesic effect of intraarticular bupivacaine. We designed this study to determine whether intraarticular magnesium sulfate or bupivacaine results in a decrease in visual analog scale (VAS) score followed by a decrease in analgesic requirement and whether their combination would provide more reduction in VAS, and subsequently less analgesic requirement, than either drug alone. ⋯ Magnesium combined with bupivacaine produces a reduction in postoperative pain when given intraarticularly in comparison to either bupivacaine or magnesium alone, or to saline placebo.

Randomized Controlled Trial Comparative StudyCombined ultrasound and neurostimulation guidance for popliteal sciatic nerve block: a prospective, randomized comparison with neurostimulation alone.
Ultrasound imaging, an effective tool to localize peripheral nerves, may facilitate block performance. However, its usefulness during popliteal sciatic nerve block has not been assessed. ⋯ Combined ultrasound and neurostimulation guidance does not decrease block time but increases the success rate of popliteal sciatic nerve block observed at 30 min.
