Current status of variations in in-hospital cardiac arrest call numbers in Japan: a nationwide survey.
The use of standardized internal hospital phone numbers for cardiac arrest is advocated in Europe. We evaluated the current status of variations in medical emergency call numbers for in-hospital patients in Japan and whether anesthesiologists would approve a standardized number. From June 2018 to August 2018, a questionnaire survey was mailed to anesthesiologists in 1373 Japanese Society of Anesthesiologists (JSA)-accredited hospitals. ⋯ Finally, 423/776 (55%) respondents approved standardizing a hospital telephone number for summoning help. Multivariate analysis showed that facilities where the anesthesiologists already memorized the call number were the only reason identified for opposition to the standardization. Although 96% of JSA-accredited hospitals had a response system for in-hospital cardiac arrests, discussions for standardization of a unified number need to be encouraged for improved emergency response.

Case ReportsMalignant hyperthermia in a 16-day-old infant with congenital diaphragmatic hernia: a case report.
Malignant hyperthermia (MH) is a severe hypermetabolic disorder associated with dysregulation of calcium homeostasis and is triggered by inhalational anesthetics (isoflurane, sevoflurane, desflurane) and a depolarizing muscle relaxant (succinylcholine). We report the case of a 16-day-old infant undergoing laparoscopic surgery. The patient developed hyperthermia and hypercarbia with muscle rigidity. ⋯ Arg530His and c.1841G > T p. Arg614Leu, which are known to be associated with MH. This was a rare case of MH in a 16-day-old infant that might be related to two RYR1 mutations inherited from the parents.

Dermatomal coverage of single-injection ultrasound-guided parasagittal approach to anterior quadratus lumborum block at the lateral supra-arcuate ligament.
The subcostal quadratus lumborum (QL) block is used in postoperative analgesia for abdominal surgery. However, only a small portion of local anesthetic can spread into the thoracic paravertebral space from the injection site via the lateral arcuate ligament, due to the barrier action of the ligament. In this study, we determined the effectiveness of a new ultrasound-guided parasagittal approach to anterior QL block at the lateral supra-arcuate ligament. ⋯ Four patients (16.7%) developed quadriceps weakness after the blocks. The parasagittal technique provides a new choice for postoperative analgesia of abdominal surgery with rapid onset and reliable dermatomal coverage.
