A 74-year-old female patient underwent a coil embolization for an unruptured cerebral aneurysm. A routine anesthetic protocol was devised as there was no risk of a difficult airway. ⋯ We changed the stylet to a Parker Flex-IT™ Stylet (Parker Medical, CO, USA), which can be freely curved by pushing the sum button on the top of the stylet. As a result, easy intubation was possible, and the DLT was maneuvered at a proper angle while examining the vocal cords by using the Parker Flex-IT™ Stylet In conclusion, when a McGRATH® MAC laryngoscope cannot be operated freely in the oral cavity owing to a limited oral opening, we can instead intubate easily and effectively by using a combination of a Parker Flex-IT™ Stylet and the McGRATH® MAC video laryngoscope.

The McGRATH® MAC videolaryngoscope (McG) is a new device for tracheal intubation. Its utility has been reported in both tracheal intubation in children and difficult tracheal intubation for adults. Initially, the blade introduced was for adult use only, but the one for children was also in the market. We examined the usefulness of the McG for tracheal intubation in 100 children. ⋯ McG is useful in both routine and difficult airway management for children.

Non-invasive positive pressure ventilation (NPPV) reduces the incidences of ventilator-associated pneumonia, the duration of ICU stay and the mortality rate compared with conventional respiratory management of the patients with acute respiratory failure (ARF). Recently, helmet NPPV equipment became available. Because of the high tolerability, the helmet seems to be the best NPPV interface when prolonged and continuous assistance is needed. In this study, we analyzed several factors related to failure of helmet NPPV in ARF patients in intensive care unit (ICU), retrospectively. ⋯ Helmet NPPV improved oxygenation in ARF patients immediately after induction of NPPV. Although there were no significant predictable parameters of unsuccessful NPPV before induction of NPPV, a lot of excretion of sputum might be suggested as a risk factor.

[Seishu Hanaoka Did Not Describe His Anesthetic as Tsusensan--A Misunderstanding of the Terms Mafutsusan and Tsusensan].
It is widespread even among medical professionals as well as medical historians that the formal term of the general anesthetic that Hanaoka developed is Tsusensan and its alias name is Mafutsusan. Hanaoka himself, however, described it as Mafutsusan in his Nyugan Chikenroku, the case report of the first breast cancer excision under general anesthesia with the anesthetic, and a large number of his disciples all used the term Mafutsusan to denote the anesthetic in their manuscripts. The description of Tsusensan has not been found in the documents written in the Edo period, and this name is detected only in the epitaph of Hanaoka. Consequently, we should refer to Hanaoka's anesththetic as "Mafutsusan, another name Tsusensan" instead of "Tsusensan, another name Mafutsusan."

[McGRATH® MAC Is Useful to Learn Tracheal Intubation Using a Macintosh Laryngoscope].
Learning tracheal intubation using a Macintosh laryngoscope (McL) is important although video laryngoscope is becoming popular. The purpose of this study was to compare the usefulness as a training device for intubation technique using McL with three devices; McGRATH® MAC (MAC), Airwayscope® (AWS) and McL. ⋯ The McGRATH® MAC may possess advantages compared to Airwayscope® and Macintosh laryngoscope as a training device for learning intubation technique using Macintosh laryngoscope and understanding anatomy of the larynx.
