Randomized Controlled Trial Comparative Study
Comparison of the anesthetic effects of remimazolam tosilate and remimazolam besylate in daytime hysteroscopic surgery.
The purpose of this study is to observe whether there is a difference in the anesthetic effect of remimazolam tosilate and remimazolam besylate in daytime hysteroscopic surgery, so as to provide reference for clinical application. ⋯ Chinese Clinical Trial Registry, ChiCTR2400081688.

Randomized Controlled Trial Comparative Study
The effect of combined pudendal nerve and spermatic cord block or caudal epidural block on postoperative analgesia after posterior urethroplasty: a randomized trial.
Postoperative pain management remains a significant challenge for patients undergoing posterior urethroplasty (PU). In a previous study, we proposed a novel technique of combined pudendal nerve (PN) and spermatic cord (SC) block to manage pain after PU. The present trial was conducted to test the hypothesis that this technique is effective for pain control after PU and provides longer-lasting analgesia than caudal epidural block (CB). ⋯ PN combined with SC block is an effective technique for postoperative analgesia in PU. This technique can achieve a longer duration of analgesia and lower pain scores, especially 12 h after surgery, than a CB.

Meta Analysis Comparative Study
The impact of epidural ropivacaine versus levobupivacaine for labor analgesia on maternal and fetal outcomes: a meta-analysis.
Newer neuraxial local anesthetic agents which have been used as epidural analgesia have shown to provide reliable pain relief during labor. Ropivacaine and levobupivacaine are newer agents now used for labor analgesia. However, even though few studies have made their comparison with bupivacaine, ropivacaine and levobupivacaine have seldom systematically been compared. Therefore, in this analysis, we aimed to systematically show the impact of epidural ropivacaine versus levobupivacaine for labor analgesia on maternal and fetal outcomes. ⋯ To conclude, our analysis showed both epidural ropivacaine and levobupivacaine to be equally effective for labor analgesia in terms of maternal and fetal outcomes. No major adverse maternal and fetal outcome was observed in this analysis. However, considering the several limitations of this analysis, further larger studies should be able to solve and clarify this issue.

IV access is a commonly performed procedure that is often taught based on tradition rather than evidence. The effect of arm retroflexion on vein width, either alone or in combination with a tourniquet or general anesthesia (GA), remains unclear. In this case, the sonographically measured vein width is a surrogate parameter for the success of the puncture. ⋯ This study provides evidence that retroflexion of the arm in supine patients, whether alone or in addition to a tourniquet or general anesthesia, does not have any additional effect on vein width as a surrogate parameter for successful IV success. It shows for the first time that general anesthesia effectively increases vein diameter.

The effectiveness of the quadratus lumborum block (QLB) for postoperative pain management depends on the injection pathway used. There is limited research on the block area produced by intramuscular injection of local anesthesia in the quadratus lumborum muscle. This study aimed to determine the cutaneous sensory blockade area produced by an intramuscular quadratus lumborum block (QLBi) at the L2 level. ⋯ June 2, 2018; ChiCTR1800016457.
