Comparative StudyDifferences in tip visibility and nerve block parameters between two echogenic needles during a simulation study with inexperienced anesthesia trainees.
Needle tip visualization during ultrasound-guided regional anesthesia (UGRA) is necessary for safety and efficacy. However, disruption of the image of the needle tip driven toward the target is a general problem, especially for beginners. The purpose of this study was to compare performance parameters between using the Sonoplex and Stimuplex D-Plus echogenic needles in a simulated ultrasound-guided interventional task by inexperienced anaesthesia residents. ⋯ The procedures that used the Sonoplex echogenic needle had significantly better tip visibility and shorter total procedure time at insertion angles between 42° and 64° relative to the phantom surface. We have demonstrated that inexperienced users who used the Sonoplex echogenic needle were able to complete the procedure more quickly. Needles with improved visibility would be a very useful addition to UGRA for inexperienced users.

Anesthetic management of peroral endoscopic myotomy for esophageal achalasia: a retrospective case series.
Peroral endoscopic myotomy (POEM) is a newly developed, less invasive treatment for esophageal achalasia that requires general anesthesia under positive pressure ventilation. In this retrospective case series, we describe the anesthetic management of 28 consecutive patients who underwent POEM for esophageal achalasia. Anesthesia was maintained with sevoflurane and remifentanil under positive pressure ventilation through a tracheal tube. ⋯ Minor subcutaneous emphysema around the neck was observed in one patient. POEM was successfully completed, and tracheas were extubated immediately after the procedure in all patients. Our findings suggest that prevention of aspiration pneumonia during anesthesia induction, preparation for carbon dioxide insufflation-related complications, and treatment of scopolamine butylbromide-induced tachycardia play important roles in safe anesthesia management of POEM for esophageal achalasia.

ReviewRegional anesthesia for laparoscopic surgery: a narrative review.
Laparoscopic surgery has advanced remarkably in recent years, resulting in reduced morbidity and shorter hospital stay compared with open surgery. Despite challenges from the expanding array of laparoscopic procedures performed with the use of pneumoperitoneum on increasingly sick patients, anesthesia has remained largely unchanged. ⋯ This narrative review is an attempt to critically summarize current evidence on regional anesthesia for laparoscopic surgery. Because most available data come from large, retrospective studies, large, rigorous, prospective clinical trials comparing regional vs. general anesthesia are needed to evaluate the true value of regional anesthesia in laparoscopic surgery.

Randomized Controlled TrialSlow injection of nefopam reduces pain intensity associated with intravenous injection: a prospective randomized trial.
We aimed to investigate the frequency and severity of pain associated with intravenous injection of nefopam and to determine whether a slow rate of administration can effectively reduce such pain. ⋯ At the slower rate of infusion (60 ml/h) of the 1.5 mg/ml nefopam solution, injection pain intensity was attenuated to a significantly greater degree than at the faster rates.
