[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."

We report anesthetic management of patients undergoing single-lumen tracheal tube ventilation with artificial pneumothorax in thoracolaparoscopic esophagectomy in prone position. No adverse effect against respiratory and circulatory management was found during esophagectomy. Single-lumen tracheal tube ventilation with artificial pneumothorax potentially is a feasible method for thoracolaparoscopic esophagectomy in prone position.

Perioperative delirium increases the morbidity and mortality in elderly patients. The present retrospective study was carried out to evaluate whether desflurane or sevoflurane has influence on the incidence of perioperative delirium. ⋯ Desflurane anesthesia is same as sevoflurane regarding perioperative delirium in elderly patients. Shorter hospitalization in group D was achieved for 10 days compared with those in group S, due to the lower incidence of delirium on POD 3 and 5 in group D.

Comparative Study
[Comparison of Postoperative Analgesic Effects between 0.25% Levobupivacaine and 0.5% Levobupivacaine Local Instillation in Inguinal Hernia Repair].
We compared retrospectively postoperative analgesia of two concentrations of levobupivacaine by local spraying in radical repair of inguinal hernia. ⋯ In inguinal hernia repair, it is possible that local spraying of 0.25% levobupivacaine exerts the same effect as 0.5% levobupivacaine.

Epidural anesthesia is a useful tool for postoperative pain control. However, inappropriate fixing of the catheter not only hinders the analgesic effect, but could lead to serious accidents as a result of the untoward removal of the epidural catheter. ⋯ The group using the Steri-Strip, was able to significantly reduce the untoward removal (P = 0.002).
