Randomized Controlled Trial Comparative StudyRocuronium Bromide Intravenous Solution Maruishi® is more suitable than ESLAX Intravenous® during rapid-sequence induction of anesthesia.
Rocuronium Bromide Intravenous Solution® (Maruishi Pharmaceutical Co., Ltd, Osaka, Japan) is a newly developed generic drug and we have noticed that compared with conventional rocuronium formulations [e.g. Esmeron (Eslax), MSD Co. Ltd., Tokyo, Japan], rocuronium Maruishi appeared to cause less pain or withdrawal movement. The aim of this study was to assess the hypothesis that the injection of rocuronium Maruishi causes less body movement than rocuronium MSD does, during rapid-sequence induction of anesthesia. ⋯ Compared with rocuronium MSD, rocuronium Maruishi is more suitable than conventional rocuronium formulations, for rapid-sequence induction of anesthesia.

Randomized Controlled Trial Comparative StudyUse of a curved needle to facilitate lateral sagittal infraclavicular block performance: a randomized clinical trial.
Failed needle-tip positioning in an ultrasound-guided infraclavicular block can be due to improper needle insertion point and steep needle insertion angle. Needle pre-curving enables the user to pass the needle with different curved trajectories on approaching the brachial plexus. Aim of the study was to compare curved and non-curved needles as regards the time needed to perform the lateral sagittal infra-clavicular block. ⋯ The use of a curved needle reduces the time required to perform the lateral sagittal infraclavicular block. The curved needle provides less procedure pain and higher satisfaction levels among anesthetists than the non-curved needle.

A laser mount probe holder facilitates fixation of the optimized ultrasound image and needle alignment in-plane to the ultrasound beam during ultrasound-guided peripheral nerve block.
Laser guidance facilitates needle alignment in-plane to the ultrasound beam. Once the ultrasound image is optimized, there is no further need to maneuver the probe. ⋯ The needle brightness was quantitatively measured using an image analysis software. We found that the laser mount probe holder is useful, not only to visualize the needle tip in the ultrasound plane, but also to fix the best ultrasound image.

Clinical TrialResting pupil size is a predictor of hypotension after induction of general anesthesia.
Arterial hypotension is a major adverse effect of general anesthesia. Patients with pre-existing autonomic dysfunction are at greater risk of hypotension. This study was performed to examine whether objective measurement of the pupillary light reflex is predictive of intraoperative hypotension. ⋯ UMIN000023729 REGISTRY URL: https://www.umin.ac.jp.
