Randomized Controlled TrialOral melatonin, dexmedetomidine, and midazolam for prevention of postoperative agitation in children.
Several studies have reported that sevoflurane was associated with a relatively high incidence of emergence agitation in children even in the absence of any surgical intervention. The aim of this study was to compare early agitation characteristics of oral melatonin, dexmedetomidine, and midazolam premedication in children who were given sevoflurane anesthesia for esophageal dilatation. ⋯ We found that oral melatonin, dexmedetomidine, and midazolam reduced the incidence of emergence agitation in children after sevoflurane anesthesia.

ReviewAnesthetic management of noncardiac surgery for patients with single ventricle physiology.
Patients with congenital heart diseases are a growing population, and noncardiac surgeries will become an important health care issue. Patients with single ventricle physiology are a particularly challenging population who will undergo staged, palliative repair toward a final step of Fontan circulation. Although Fontan surgery creates a serial circulation in which the ventricle pumps blood to the systemic circuit, pulmonary blood flow occurs without a dedicated ventricle. ⋯ Health care professionals must prepare for these patients to present to noncardiac surgery at any stage of intervention, possibly with complications. Given that staged, palliative repair has undergone multiple modifications, patients who present for surgery can vary in types and timing of the repair. Anesthesiologists who care for them must be familiar with perioperative issues to optimize outcomes, especially because congenital heart disease is a risk factor for increased mortality for noncardiac surgery.

Scientific publications in anesthesiology journals from East Asia: a 10-year survey of the literature.
The scientific publications in anesthesiology research from East Asian authors have not been reported yet. The present study was designed to analyze the contribution of articles from East Asia to anesthesiology research. Articles published in 17 journals in anesthesiology originating from Japan, China, and South Korea from 2000 to 2009 were retrieved from the PubMed database and Web of Science. ⋯ Our analysis showed that Japan was the most productive region in East Asia, but there was a notable decrease in publications from Japan in 2000-2009. The impact factor of the articles suggests similar levels of scholarship. Anesthesia & Analgesia was the most popular journal in East Asia.

Case ReportsEpiglottic prolapse induced by lighted stylet tracheal intubation.
We report a case of epiglottic prolapse induced by lighted stylet tracheal intubation perceived by following upper gastrointestinal endoscopy. A 68-year-old male was to undergo endoscopic mucosal resection (EMR) under general anesthesia for a superficial orolarynx cancer spreading over the root of the tongue. Because the mucosal change was so minimal, intubation was performed with a lighted stylet instead of a direct laryngoscope, to prevent its metal blade spoiling the delicate endoscopic findings. ⋯ The postoperative course was uneventful and he was discharged on the sixth postoperative day. Retrospective evaluation of preoperative gastrointestinal endoscopy showed the epiglottis was flat and thin enough to have a tendency to become attached to the posterior pharynx wall, even though the procedure was performed in the decubitus position. Epiglottic prolapse induced by lighted stylet tracheal intubation is a quite rare complication but we should be aware of it as a potential injury which could cause upper airway obstruction if not recognized before extubation.

The effect of one-lung ventilation upon pulmonary inflammatory responses during lung resection.
One-lung ventilation (OLV) is commonly used during thoracic surgery. Clinical studies using bronchoalveolar lavage fluid analysis have demonstrated that OLV induces pulmonary inflammatory reactions in the ventilated dependent lung. However, few clinical studies have investigated such inflammatory reactions in the dependent lung compared with the collapsed nondependent lung. Here we used a bronchoscopic microsampling method to obtain epithelial lining fluid (ELF) from each lung, and then compared the inflammatory reactions in the dependent lung and the nondependent lung during thoracic surgery. ⋯ One-lung ventilation induced inflammatory responses of the bronchial epithelia in the dependent lung and the nondependent lung during thoracic surgery. In addition, these inflammatory responses were more augmented in the dependent lung than in the nondependent lung.
